etbeRacism in the Office

Today I was at an office party and the conversation turned to race, specifically the incidence of unarmed Afro-American men and boys who are shot by police. Apparently the idea that white people (even in other countries) might treat non-white people badly offends some people, so we had a man try to explain that Afro-Americans commit more crime and therefore are more likely to get shot. This part of the discussion isn’t even noteworthy, it’s the sort of thing that happens all the time.

I and another man pointed out that crime is correlated with poverty and racism causes non-white people to be disproportionately poor. We also pointed out that US police seem capable of arresting proven violent white criminals without shooting them (he cited arrests of Mafia members I cited mass murderers like the one who shot up the cinema). This part of the discussion isn’t particularly noteworthy either. Usually when someone tries explaining some racist ideas and gets firm disagreement they back down. But not this time.

The next step was the issue of whether black people are inherently violent. He cited all of Africa as evidence. There’s a meme that you shouldn’t accuse someone of being racist, it’s apparently very offensive. I find racism very offensive and speak the truth about it. So all the following discussion was peppered with him complaining about how offended he was and me not caring (stop saying racist things if you don’t want me to call you racist).

Next was an appeal to “statistics” and “facts”. He said that he was only citing statistics and facts, clearly not understanding that saying “Africans are violent” is not a statistic. I told him to get his phone and Google for some statistics as he hadn’t cited any. I thought that might make him just go away, it was clear that we were long past the possibility of agreeing on these issues. I don’t go to parties seeking out such arguments, in fact I’d rather avoid such people altogether if possible.

So he found an article about recent immigrants from Somalia in Melbourne (not about the US or Africa, the previous topics of discussion). We are having ongoing discussions in Australia about violent crime, mainly due to conservatives who want to break international agreements regarding the treatment of refugees. For the record I support stronger jail sentences for violent crime, but this is an idea that is not well accepted by conservatives presumably because the vast majority of violent criminals are white (due to the vast majority of the Australian population being white).

His next claim was that Africans are genetically violent due to DNA changes from violence in the past. He specifically said that if someone was a witness to violence it would change their DNA to make them and their children more violent. He also specifically said that this was due to thousands of years of violence in Africa (he mentioned two thousand and three thousand years on different occasions). I pointed out that European history has plenty of violence that is well documented and also that DNA just doesn’t work the way he thinks it does.

Of course he tried to shout me down about the issue of DNA, telling me that he studied Psychology at a university in London and knows how DNA works, demanding to know my qualifications, and asserting that any scientist would support him. I don’t have a medical degree, but I have spent quite a lot of time attending lectures on medical research including from researchers who deliberately change DNA to study how this changes the biological processes of the organism in question.

I offered him the opportunity to star in a Youtube video about this, I’d record everything he wants to say about DNA. But he regarded that offer as an attempt to “shame” him because of his “controversial” views. It was a strange and sudden change from “any scientist will support me” to “it’s controversial”. Unfortunately he didn’t give up on his attempts to convince me that he wasn’t racist and that black people are lesser.

The next odd thing was when he asked me “what do you call them” (black people), “do you call them Afro-Americans when they are here”. I explained that if an American of African ancestry visits Australia then you would call them Afro-American, otherwise not. It’s strange that someone goes from being so certain of so many things to not knowing the basics. In retrospect I should have asked whether he was aware that there are black people who aren’t African.

Then I sought opinions from other people at the party regarding DNA modifications. While I didn’t expect to immediately convince him of the error of his ways it should at least demonstrate that I’m not the one who’s in a minority regarding this issue. As expected there was no support for the ideas of DNA modifying. During that discussion I mentioned radiation as a cause of DNA changes. He then came up with the idea that radiation from someone’s mouth when they shout at you could change your DNA. This was the subject of some jokes, one man said something like “my parents shouted at me a lot but didn’t make me a mutant”.

The other people had some sensible things to say, pointing out that psychological trauma changes the way people raise children and can have multi-generational effects. But the idea of events 3000 years ago having such effects was ridiculed.

By this time people were starting to leave. A heated discussion of racism tends to kill the party atmosphere. There might be some people who think I should have just avoided the discussion to keep the party going (really I didn’t want it and tried to end it). But I’m not going to allow a racist to think that I agree with them, and if having a party requires any form of agreement to racism then it’s not a party I care about.

As I was getting ready to leave the man said that he thought he didn’t explain things well because he was tipsy. I disagree, I think he explained some things very well. When someone goes to such extraordinary lengths to criticise all black people after a discussion of white cops killing unarmed black people I think it shows their character. But I did offer some friendly advice, “don’t drink with people you work with or for or any other people you want to impress”, I suggested that maybe quitting alcohol altogether is the right thing to do if this is what it causes. But he still thought it was wrong of me to call him racist, and I still don’t care. Alcohol doesn’t make anyone suddenly think that black people are inherently dangerous (even when unarmed) and therefore deserving of being shot by police (disregarding the fact that police can take members of the Mafia alive). But it does make people less inhibited about sharing such views even when it’s clear that they don’t have an accepting audience.

Some Final Notes

I was not looking for an argument or trying to entrap him in any way. I refrained from asking him about other races who have experienced violence in the past, maybe he would have made similar claims about other non-white races and maybe he wouldn’t, I didn’t try to broaden the scope of the dispute.

I am not going to do anything that might be taken as agreement or support of racism unless faced with the threat of violence. He did not threaten me so I wasn’t going to back down from the debate.

I gave him multiple opportunities to leave the debate. When I insisted that he find statistics to support his cause I hoped and expected that he would depart. Instead he came back with a page about the latest racist dog-whistle in Australian politics which had no correlation with anything we had previously discussed.

I think the fact that this debate happened says something about Australian and British culture. This man apparently hadn’t had people push back on such ideas before.

etbeWordPress Multisite on Debian

WordPress (a common CMS for blogs) is designed to be copied to a directory that Apache can serve and run by a user with no particular privileges while managing installation of it’s own updates and plugins. Debian is designed around the idea of the package management system controlling everything on behalf of a sysadmin.

When I first started using WordPress there was a version called “WordPress MU” (Multi User) which supported multiple blogs. It was a separate archive to the main WordPress and didn’t support all the plugins and themes. As a main selling point of WordPress is the ability to select from the significant library of plugins and themes this was a serious problem.

Debian WordPress

The people who maintain the Debian package of WordPress have always supported multiple blogs on one system and made it very easy to run in that manner. There’s a /etc/wordpress directory for configuration files for each blog with names such as config-etbe.coker.com.au.php. This allows having multiple separate blogs running from the same tree of PHP source which means only one thing to update when there’s a new version of WordPress (often fixing security issues).

One thing that appears to be lacking with the Debian system is separate directories for “media”. WordPress supports uploading images (which are scaled to several different sizes) as well as sound and apparently video. By default under Debian they are stored in /var/lib/wordpress/wp-content/uploads/YYYY/MM/filename. If you have several blogs on one system they all get to share the same directory tree, that may be OK for one person running multiple blogs but is obviously bad when several bloggers have independent blogs on the same server.

Multisite

If you enable the “multisite” support in WordPress then you have WordPress support for multiple blogs. The administrator of the multisite configuration has the ability to specify media paths etc for all the child blogs.

The first problem with this is that one person has to be the multisite administrator. As I’m the sysadmin of the WordPress servers in question that’s an obvious task for me. But the problem is that the multisite administrator doesn’t just do sysadmin tasks such as specifying storage directories. They also do fairly routine tasks like enabling plugins. Preventing bloggers from installing new plugins is reasonable and is the default Debian configuration. Preventing them from selecting which of the installed plugins are activated is unreasonable in most situations.

The next issue is that some core parts of WordPress functionality on the sub-blogs refer to the administrator blog, recovering a forgotten password is one example. I don’t want users of other blogs on the system to be referred to my blog when they forget their password.

A final problem with multisite is that it makes things more difficult if you want to move a blog to another system. Instead of just sending a dump of the MySQL database and a copy of the Apache configuration for the site you have to configure it for which blog will be it’s master. If going between multisite and non-multisite you have to change some of the data about accounts, this will be annoying on both adding new sites to a server and moving sites from the server to a non-multisite server somewhere else.

I now believe that WordPress multisite has little value for people who use Debian. The Debian way is the better way.

So I had to back out the multisite changes. Fortunately I had a cron job to make snapshots of the BTRFS subvolume that has the database so it was easy to revert to an older version of the MySQL configuration.

Upload Location

update etbe_options set option_value='/var/lib/wordpress/wp-content/uploads/etbe.coker.com.au' where option_name='upload_path';

It turns out that if you don’t have a multisite blog then there’s no way of changing the upload directory without using SQL. The above SQL code is an example of how to do this. Note that it seems that there is special case handling of a value of ‘wp-content/uploads‘ and any other path needs to be fully qualified.

For my own blog however I choose to avoid the WordPress media management and use the following shell script to create suitable HTML code for an image that links to a high resolution version. I use GIMP to create the smaller version of the image which gives me a lot of control over how to crop and compress the image to ensure that enough detail is visible while still being small enough for fast download.

#!/bin/bash
set -e

if [ "$BASE" = "" ]; then
  BASE="http://www.coker.com.au/blogpics/2018"
fi

while [ "$1" != "" ]; do
  BIG=$1
  SMALL=$(echo $1 | sed -s s/-big//)
  RES=$(identify $SMALL|cut -f3 -d\ )
  WIDTH=$(($(echo $RES|cut -f1 -dx)/2))px
  HEIGHT=$(($(echo $RES|cut -f2 -dx)/2))px
  echo "<a href=\"$BASE/$BIG\"><img src=\"$BASE/$SMALL\" width=\"$WIDTH\" height=\"$HEIGHT\" alt=\"\" /></a>"
  shift
done

etbeCompromised Guest Account

Some of the workstations I run are sometimes used by multiple people. Having multiple people share an account is bad for security so having a guest account for guest access is convenient.

If a system doesn’t allow logins over the Internet then a strong password is not needed for the guest account.

If such a system later allows logins over the Internet then hostile parties can try to guess the password. This happens even if you don’t use the default port for ssh.

This recently happened to a system I run. The attacker logged in as guest, changed the password, and installed a cron job to run every minute and restart their blockchain mining program if it had been stopped.

In 2007 a bug was filed against the Debian package openssh-server requesting that the AllowUsers be added to the default /etc/ssh/sshd_config file [1]. If that bug hadn’t been marked as “wishlist” and left alone for 11 years then I would probably have set it to only allow ssh connections to the one account that I desired which always had a strong password.

I’ve been a sysadmin for about 25 years (since before ssh was invented). I have been a Debian Developer for almost 20 years, including working on security related code. The fact that I stuffed up in regard to this issue suggests that there are probably many other people making similar mistakes, and probably most of them aren’t monitoring things like system load average and temperature which can lead to the discovery of such attacks.

etbeDell PowerEdge T30

I just did a Debian install on a Dell PowerEdge T30 for a client. The Dell web site is a bit broken at the moment, it didn’t list the price of that server or give useful specs when I was ordering it. I was under the impression that the server was limited to 8G of RAM, that’s unusually small but it wouldn’t be the first time a vendor crippled a low end model to drive sales of more expensive systems. It turned out that the T30 model I got has 4*DDR4 sockets with only one used for an 8G DIMM. It apparently can handle up to 64G of RAM.

It has space for 4*3.5″ SATA disks but only has 4*SATA connectors on the motherboard. As I never use the DVD in a server this isn’t a problem for me, but if you want 4 disks and a DVD then you need to buy a PCI or PCIe SATA card.

Compared to the PowerEdge T130 I’m using at home the new T30 is slightly shorter and thinner while seeming to have more space inside. This is partly due to better design and partly due to having 2 hard drives in the top near the DVD drive which are a little inconvenient to get to. The T130 I have (which isn’t the latest model) has 4*3.5″ SATA drive bays at the bottom which are very convenient for swapping disks.

It has two PCIe*16 slots (one of which is apparently quad speed), one shorter PCIe slot, and a PCI slot. For a cheap server a PCI slot is a nice feature, it means I can use an old PCI Ethernet card instead of buying a PCIe Ethernet card. The T30 cost $1002 so using an old Ethernet card saved 1% of the overall cost.

The T30 seems designed to be more of a workstation or personal server than a straight server. The previous iterations of the low end tower servers from Dell didn’t have built in sound and had PCIe slots that were adequate for a RAID controller but vastly inadequate for video. This one has built in line in and out for audio and has two DisplayPort connectors on the motherboard (presumably for dual-head support). Apart from the CPU (an E3-1225 which is slower than some systems people are throwing out nowadays) the system would be a decent gaming system.

It has lots of USB ports which is handy for a file server, I can attach lots of backup devices. Also most of the ports support “super speed”, I haven’t yet tested out USB devices that support such speeds but I’m looking forward to it. It’s a pity that there are no USB-C ports.

One deficiency of the T30 is the lack of a VGA port. It has one HDMI and two DisplayPort sockets on the motherboard, this is really great for a system on or under your desk, any monitor you would want on your desk will support at least one of those interfaces. But in a server room you tend to have an old VGA monitor that’s there because no-one wants it on their desk. Not supporting VGA may force people to buy a $200 monitor for their server room. That increases the effective cost of the system by 20%. It has a PC serial port on the motherboard which is a nice server feature, but that doesn’t make up for the lack of VGA.

The BIOS configuration has an option displayed for enabling charging devices from USB sockets when a laptop is in sleep mode. It’s disappointing that they didn’t either make a BIOS build for a non-laptop or have the BIOS detect at run-time that it’s not on laptop hardware and hide that.

Conclusion

The PowerEdge T30 is a nice low-end workstation. If you want a system with ECC RAM because you need it to be reliable and you don’t need the greatest performance then it will do very well. It has Intel video on the motherboard with HDMI and DisplayPort connectors, this won’t be the fastest video but should do for most workstation tasks. It has a PCIe*16 quad speed slot in case you want to install a really fast video card. The CPU is slow by today’s standards, but Dell sells plenty of tower systems that support faster CPUs.

It’s nice that it has a serial port on the motherboard. That could be used for a serial console or could be used to talk to a UPS or other server-room equipment. But that doesn’t make up for the lack of VGA support IMHO.

One could say that a tower system is designed to be a desktop or desk-side system not run in any sort of server room. However it is cheaper than any rack mounted systems from Dell so it will be deployed in lots of small businesses that have one server for everything – I will probably install them in several other small businesses this year. Also tower servers do end up being deployed in server rooms, all it takes is a small business moving to a serviced office that has a proper server room and the old tower servers end up in a rack.

Rack vs Tower

One reason for small businesses to use tower servers when rack servers are more appropriate is the issue of noise. If your “server room” is the room that has your printer and fax then it typically won’t have a door and you just can’t have the noise of a rack mounted server in there. 1RU systems are inherently noisy because the small diameter of the fans means that they have to spin fast. 2RU systems can be made relatively quiet if you don’t have high-end CPUs but no-one seems to be trying to do that.

I think it would be nice if a company like Dell sold low-end servers in a rack mount form-factor (19 inches wide and 2RU high) that were designed to be relatively quiet. Then instead of starting with a tower server and ending up with tower systems in racks a small business could start with a 19 inch wide system on a shelf that gets bolted into a rack if they move into a better office. Any laptop CPU from the last 10 years is capable of running a file server with 8 disks in a ZFS array. Any modern laptop CPU is capable of running a file server with 8 SSDs in a ZFS array. This wouldn’t be difficult to design.

Dave HallDrupal Puppies

Over the years Drupal distributions, or distros as they're more affectionately known, have evolved a lot. We started off passing around database dumps. Eventually we moved onto using installations profiles and features to share par-baked sites.

There are some signs that distros aren't working for people using them. Agencies often hack a distro to meet client requirements. This happens because it is often difficult to cleanly extend a distro. A content type might need extra fields or the logic in an alter hook may not be desired. This makes it difficult to maintain sites built on distros. Other times maintainers abandon their distributions. This leaves site owners with an unexpected maintenance burden.

We should recognise how people are using distros and try to cater to them better. My observations suggest there are 2 types of Drupal distributions; starter kits and targeted products.

Targeted products are easier to deal with. Increasingly monetising targeted distro products is done through a SaaS offering. The revenue can funds the ongoing development of the product. This can help ensure the project remains sustainable. There are signs that this is a viable way of building Drupal 8 based products. We should be encouraging companies to embrace a strategy built around open SaaS. Open Social is a great example of this approach. Releasing the distros demonstrates a commitment to the business model. Often the secret sauce isn't in the code, it is the team and services built around the product.

Many Drupal 7 based distros struggled to articulate their use case. It was difficult to know if they were a product, a demo or a community project that you extend. Open Atrium and Commerce Kickstart are examples of distros with an identity crisis. We need to reconceptualise most distros as "starter kits" or as I like to call them "puppies".

Why puppies? Once you take a puppy home it becomes your responsibility. Starter kits should be the same. You should never assume that a starter kit will offer an upgrade path from one release to the next. When you install a starter kit you are responsible for updating the modules yourself. You need to keep track of security releases. If your puppy leaves a mess on the carpet, no one else will clean it up.

Sites build on top of a starter kit should diverge from the original version. This shouldn't only be an expectation, it should be encouraged. Installing a starter kit is the starting point of building a unique fork.

Project pages should clearly state that users are buying a puppy. Prospective puppy owners should know if they're about to take home a little lap dog or one that will grow to the size of a pony that needs daily exercise. Puppy breeders (developers) should not feel compelled to do anything once releasing the puppy. That said, most users would like some documentation.

I know of several agencies and large organisations that are making use of starter kits. Let's support people who are adopting this approach. As a community we should acknowledge that distros aren't working. We should start working out how best to manage the transition to puppies.

Dave HallTrying Drupal

While preparing for my DrupalCamp Belgium keynote presentation I looked at how easy it is to get started with various CMS platforms. For my talk I used Contentful, a hosted content as a service CMS platform and contrasted that to the "Try Drupal" experience. Below is the walk through of both.

Let's start with Contentful. I start off by visiting their website.

Contentful homepage

In the top right corner is a blue button encouraging me to "try for free". I hit the link and I'm presented with a sign up form. I can even use Google or GitHub for authentication if I want.

Contentful signup form

While my example site is being installed I am presented with an overview of what I can do once it is finished. It takes around 30 seconds for the site to be installed.

Contentful installer wait

My site is installed and I'm given some guidance about what to do next. There is even an onboarding tour in the bottom right corner that is waving at me.

Contentful dashboard

Overall this took around a minute and required very little thought. I never once found myself thinking come on hurry up.

Now let's see what it is like to try Drupal. I land on d.o. I see a big prominent "Try Drupal" button, so I click that.

Drupal homepage

I am presented with 3 options. I am not sure why I'm being presented options to "Build on Drupal 8 for Free" or to "Get Started Risk-Free", I just want to try Drupal, so I go with Pantheon.

Try Drupal providers

Like with Contentful I'm asked to create an account. Again I have the option of using Google for the sign up or completing a form. This form has more fields than contentful.

Pantheon signup page

I've created my account and I am expecting to be dropped into a demo Drupal site. Instead I am presented with a dashboard. The most prominent call to action is importing a site. I decide to create a new site.

Pantheon dashboard

I have to now think of a name for my site. This is already feeling like a lot of work just to try Drupal. If I was a busy manager I would have probably given up by this point.

Pantheon create site form

When I submit the form I must surely be going to see a Drupal site. No, sorry. I am given the choice of installing WordPress, yes WordPress, Drupal 8 or Drupal 7. Despite being very confused I go with Drupal 8.

Pantheon choose application page

Now my site is deploying. While this happens there is a bunch of items that update above the progress bar. They're all a bit nerdy, but at least I know something is happening. Why is my only option to visit my dashboard again? I want to try Drupal.

Pantheon site installer page

I land on the dashboard. Now I'm really confused. This all looks pretty geeky. I want to try Drupal not deal with code, connection modes and the like. If I stick around I might eventually click "Visit Development site", which doesn't really feel like trying Drupal.

Pantheon site dashboard

Now I'm asked to select a language. OK so Drupal supports multiple languages, that nice. Let's select English so I can finally get to try Drupal.

Drupal installer, language selection

Next I need to chose an installation profile. What is an installation profile? Which one is best for me?

Drupal installer, choose installation profile

Now I need to create an account. About 10 minutes I already created an account. Why do I need to create another one? I also named my site earlier in the process.

Drupal installer, configuration form part 1
Drupal installer, configuration form part 2

Finally I am dropped into a Drupal 8 site. There is nothing to guide me on what to do next.

Drupal site homepage

I am left with a sense that setting up Contentful is super easy and Drupal is a lot of work. For most people wanting to try Drupal they would have abandoned someway through the process. I would love to see the conversion stats for the try Drupal service. It must miniscule.

It is worth noting that Pantheon has the best user experience of the 3 companies. The process with 1&1 just dumps me at a hosting sign up page. How does that let me try Drupal?

Acquia drops onto a page where you select your role, then you're presented with some marketing stuff and a form to request a demo. That is unless you're running an ad blocker, then when you select your role you get an Ajax error.

The Try Drupal program generates revenue for the Drupal Association. This money helps fund development of the project. I'm well aware that the DA needs money. At the same time I wonder if it is worth it. For many people this is the first experience they have using Drupal.

The previous attempt to have simplytest.me added to the try Drupal page ultimately failed due to the financial implications. While this is disappointing I don't think simplytest.me is necessarily the answer either.

There needs to be some minimum standards for the Try Drupal page. One of the key item is the number of clicks to get from d.o to a working demo site. Without this the "Try Drupal" page will drive people away from the project, which isn't the intention.

If you're at DrupalCon Vienna and want to discuss this and other ways to improve the marketing of Drupal, please attend the marketing sprints.

Stewart SmithFedora 25 + Lenovo X1 Carbon 4th Gen + OneLink+ Dock

As of May 29th 2017, if you want to do something crazy like use *both* ports of the OneLink+ dock to use monitors that aren’t 640×480 (but aren’t 4k), you’re going to need a 4.11 kernel, as everything else (for example 4.10.17, which is the latest in Fedora 25 at time of writing) will end you in a world of horrible, horrible pain.

To install, run this:

sudo dnf install \
https://kojipkgs.fedoraproject.org//packages/kernel/4.11.3/200.fc25/x86_64/kernel-4.11.3-200.fc25.x86_64.rpm \

This grabs a kernel that’s sitting in testing and isn’t yet in the main repositories. However, I can now see things on monitors, rather than 0 to 1 monitor (most often 0). You can also dock/undock and everything doesn’t crash in a pile of fail.

I remember a time when you could fairly reliably buy Intel hardware and have it “just work” with the latest distros. It’s unfortunate that this is no longer the case, and it’s more of a case of “wait six months and you’ll still have problems”.

Urgh.

(at least Wayland and X were bug for bug compatible?)

Stewart SmithAPI, ABI and backwards compatibility are a hard necessity

Recently, I was reading a thread on LKML on a proposal to change the behavior of the open system call when confronted with unknown flags. The thread is worth a read as the topic of augmenting things that exist probably by accident to be “better” is always interesting, as is the definition of “better”.

Keeping API and/or ABI compatibility is something that isn’t a new problem, and it’s one that people are pretty good at sometimes messing up.

This problem does not go away just because “we have cloud now”. In any distributed system, in order to upgrade it (or “be agile” as the kids are calling it), you by definition are going to have either downtime or at least two versions running concurrently. Thus, you have to have your interfaces/RPCs/APIs/ABIs/protocols/whatever cope with changes.

You cannot instantly upgrade the world, it happens gradually. You also have to design for at least three concurrent versions running. One is the original, the second is your upgrade, your third is the urgent fix because the upgrade is quite broken in some new way you only discover in production.

So, the way you do this? Never ever EVER design for N-1 compatibility only. Design for going back a long way, much longer than you officially support. You want to have a design and programming culture of backwards compatibility to ensure you can both do new and exciting things and experiment off to the side.

It’s worth going and rereading Rusty’s API levels posts from 2008:

Dave HallContinuing the Conversation at DrupalCon and Into the Future

My blog post from last week was very well received and sparked a conversation in the Drupal community about the future of Drupal. That conversation has continued this week at DrupalCon Baltimore.

Yesterday during the opening keynote, Dries touched on some of the issues raised in my blog post. Later in the day we held an unofficial BoF. The turn out was smaller than I expected, but we had a great discussion.

Drupal moving from a hobbyist and business tool to being an enterprise CMS for creating "ambitious digital experiences" was raised in the Driesnote and in other conversations including the BoF. We need to acknowledge that this has happened and consider it an achievement. Some people have been left behind as Drupal has grown up. There is probably more we can do to help these people. Do we need more resources to help them skill up? Should we direct them towards WordPress, backdrop, squarespace, wix etc? Is it is possible to build smaller sites that eventually grow into larger sites?

In my original blog post I talked about "peak Drupal" and used metrics that supported this assertion. One metric missing from that post is dollars spent on Drupal. It is clear that the picture is very different when measuring success using budgets. There is a general sense that a lot of money is being spent on high end Drupal sites. This has resulted in less sites doing more with Drupal 8.

As often happens when trying to solve problems with Drupal during the BoF descended into talking technical solutions. Technical solutions and implementation detail have a place. I think it is important for the community to move beyond this and start talking about Drupal as a product.

In my mind Drupal core should be a content management framework and content hub service for building compelling digital experiences. For the record, I am not arguing Drupal should become API only. Larger users will take this and build their digital stack on top of this platform. This same platform should support an ecosystem of Drupal "distros". These product focused projects target specific use cases. Great examples of such distros include Lightning, Thunder, Open Social, aGov and Drupal Commerce. For smaller agencies and sites a distro can provide a great starting point for building new Drupal 8 sites.

The biggest challenge I see is continuing this conversation as a community. The majority of the community toolkit is focused on facilitating technical discussions and implementations. These tools will be valuable as we move from talking to doing, but right now we need tools and processes for engaging in silver discussions so we can build platinum level products.

Dave HallMany People Want To Talk

WOW! The response to my blog post on the future of Drupal earlier this week has been phenomenal. My blog saw more traffic in 24 hours than it normally sees in a 2 to 3 week period. Around 30 comments have been left by readers. My tweet announcing the post was the top Drupal tweet for a day. Some 50 hours later it is still number 4.

It seems to really connected with many people in the community. I am still reflecting on everyone's contributions. There is a lot to take in. Rather than rush a follow up that responds to the issues raised, I will take some time to gather my thoughts.

One thing that is clear is that many people want to use DrupalCon Baltimore next week to discuss this issue. I encourage people to turn up with an open mind and engage in the conversation there.

A few people have suggested a BoF. Unfortunately all of the official BoF slots are full. Rather than that be a blocker, I've decided to run an unofficial BoF on the first day. I hope this helps facilitate the conversation.

Unofficial BoF: The Future of Drupal

When: Tuesday 25 April 2017 @ 12:30-1:30pm
Where: Exhibit Hall - meet at the Digital Echidna booth (#402) to be directed to the group
What: High level discussion about the direction people think Drupal should take.
UPDATE: An earlier version of this post had this scheduled for Monday. It is definitely happening on Tuesday.

I hope to see you in Baltimore.

Julien GoodwinMaking a USB powered soldering iron that doesn't suck

Today's evil project was inspired by a suggestion after my talk on USB-C & USB-PD at this years's linux.conf.au Open Hardware miniconf.

Using a knock-off Hakko driver and handpiece I've created what may be the first USB powered soldering iron that doesn't suck (ok, it's not a great iron, but at least it has sufficient power to be usable).

Building this was actually trivial, I just wired the 20v output of one of my USB-C ThinkPad boards to a generic Hakko driver board, the loss of power from using 20v not 24v is noticeable, but for small work this would be fine (I solder in either the work lab or my home lab, where both have very nice soldering stations so I don't actually expect to ever use this).

If you were to turn this into a real product you could in fact do much better, by doing both power negotiation and temperature control in a single micro, the driver could instead be switched to a boost converter instead of just a FET, and by controlling the output voltage control the power draw, and simply disable the regulator to turn off the heater. By chance, the heater resistance of the Hakko 907 clone handpieces is such that combined with USB-PD power rules you'd always be boost converting, never needing to reduce voltage.

With such a driver you could run this from anything starting with a 5v USB-C phone charger or battery (15W for the nicer ones), 9v at up to 3A off some laptops (for ~25W), or all the way to 20V@5A for those who need an extremely high-power iron. 60W, which happens to be the standard power level of many good irons (such as the Hakko FX-888D) is also at 20v@3A a common limit for chargers (and also many cables, only fixed cables, or those specially marked with an ID chip can go all the way to 5A). As higher power USB-C batteries start becoming available for laptops this becomes a real option for on-the-go use.

Here's a photo of it running from a Chromebook Pixel charger:

Stewart Smithj-core + Numato Spartan 6 board + Fedora 25

A couple of changes to http://j-core.org/#download_bitstream made it easy for me to get going:

  • In order to make ModemManager not try to think it’s a “modem”, create /etc/udev/rules.d/52-numato.rules with the following content:
    # Make ModemManager ignore Numato FPGA board
    ATTRS{idVendor}=="2a19", ATTRS{idProduct}=="1002", ENV{ID_MM_DEVICE_IGNORE}="1"
  • You will need to install python3-pyserial and minicom
  • The minicom command line i used was:
    sudo stty -F /dev/ttyACM0 -crtscts && minicom -b 115200 -D /dev/ttyACM0

and along with the instructions on j-core.org, I got it to load a known good build.

Julien GoodwinCharging my ThinkPad X1 Gen4 using USB-C

As with many massive time-sucking rabbit holes in my life, this one starts with one of my silly ideas getting egged on by some of my colleagues in London (who know full well who they are), but for a nice change, this is something I can talk about.

I have a rather excessive number of laptops, at the moment my three main ones are a rather ancient Lenovo T430 (personal), a Lenovo X1 Gen4, and a Chromebook Pixel 2 (both work).

At the start of last year I had a T430s in place of the X1, and was planning on replacing both it and my personal ThinkPad mid-year. However both of those older laptops used Lenovo's long-held (back to the IBM days) barrel charger, which lead to me having a heap of them in various locations at home and work, but all the newer machines switched to their newer rectangular "slim" style power connector and while adapters exist, I decided to go in a different direction.

One of the less-touted features of USB-C is USB-PD[1], which allows devices to be fed up to 100W of power, and can do so while using the port for data (or the other great feature of USB-C, alternate modes, such as DisplayPort, great for docks), which is starting to be used as a way to charge laptops, such as the Chromebook Pixel 2, various models of the Apple MacBook line, and more.

Instead of buying a heap of slim-style Lenovo chargers, or a load of adapters (which would inevitably disappear over time) I decided to bridge towards the future by making an adapter to allow me to charge slim-type ThinkPads (at least the smaller ones, not the portable workstations which demand 120W or more).

After doing some research on what USB-PD platforms were available at the time I settled on the TI TPS65986 chip, which, with only an external flash chip, would do all that I needed.

Devkits were ordered to experiment with, and prove the concept, which they did very quickly, so I started on building the circuit, since just reusing the devkit boards would lead to an adapter larger than would be sensible. As the TI chip is a many-pin BGA, and breaking it out on 2-layers would probably be too hard for my meager PCB design skills, I needed a 4-layer board, so I decided to use KiCad for the project.

It took me about a week of evenings to get the schematic fully sorted, with much of the time spent reading the chip datasheet, or digging through the devkit schematic to see what they did there for some cases that weren't clear, then almost a month for the actual PCB layout, with much of the time being sucked up learning a tool that was brand new to me, and also fairly obtuse.

By mid-June I had a PCB which should (but, spoiler, wouldn't) work, however as mentioned the TI chip is a 96-ball 3x3mm BGA, something I had no hope of manually placing for reflow, and of course, no hope of hand soldering, so I would need to get these manufactured commercially. Luckily there are several options for small scale assembly at very reasonable prices, and I decided to try a new company still (at the time of ordering) in closed trials, PCB.NG, they have a nice simple procedure to upload board files, and a slightly custom pick & place file that includes references to the exact component I want by Digikey[link] part number. Best of all the pricing was completely reasonable, with a first test run of six boards only costing my US$30 each.

Late in June I recieved a mail from PCB.NG telling me that they'd built my boards, but that I had made a mistake with the footprint I'd used for the USB-C connector and they were posting my boards along with the connectors. As I'd had them ship the order to California (at the time they didn't seem to offer international shipping) it took a while for them to arrive in Sydney, courtesy a coworker.

I tried to modify a connector by removing all through hole board locks, keeping just the surface mount pins, however I was unsuccessful, and that's where the project stalled until mid-October when I was in California myself, and was able to get help from a coworker who can perform miracles of surface mount soldering (while they were working on my board they were also dead-bug mounting a BGA). Sadly while I now had a board I could test it simply dropped off my priority list for months.

At the start of January another of my colleagues (a US-based teammate of the London rabble-rousers) asked for a status update, which prompted me to get off my butt and perform the testing. The next day I added some reinforcement to the connector which was only really held on by the surface mount pins, and was highly likely to rip off the board, so I covered it in epoxy. Then I knocked up some USB A plug/socket to bare wires test adapters using some stuff from the junk bin we have at the office maker space for just this sort of occasion (the socket was actually a front panel USB port from an old IBM x-series server). With some trepidation I plugged the board into my newly built & tested adapter, and powered the board from a lab supply set to limit current in case I'd any shorts in the board. It all came up straight away, and even lit the LEDs I'd added for some user feedback.

Next was to load a firmware for the chip. I'd previously used TI's tool to create a firmware image, and after some messing around with the SPI flash programmer I'd purchased managed to get the board programmed. However the behaviour of the board didn't change with (what I thought was) real firmware, I used an oscilloscope to verify the flash was being read, and a twinkie to sniff the PD negotiation, which confirmed that no request for 20v was being sent. This was where I finished that day.

Over the weekend that followed I dug into what I'd seen and determined that either I'd killed the SPI MISO port (the programmer I used was 5v, not 3.3v), or I just had bad firmware and the chip had some good defaults. I created a new firmware image from scratch, and loaded that.

Sure enough it worked first try. Once I confirmed 20v was coming from the output ports I attached it to my recently acquired HP 6051A DC load where it happily sank 45W for a while, then I attached the cable part of a Lenovo barrel to slim adapter and plugged it into my X1 where it started charging right away.

At linux.conf.au last week I gave (part of) a hardware miniconf talk about USB-C & USB-PD, which open source hardware folk might be interested in. Over the last few days while visiting my dad down in Gippsland I made the edits to fix the footprint and sent a new rev to the manufacturer for some new experiments.

Of course at CES Lenovo announced that this years ThinkPads would feature USB-C ports and allow charging through them, and due to laziness I never got around to replacing my T430, so I'm planning to order a T470 as soon as they're available, making my adapter obsolete.





Rough timeline:
  • April 21st 2016, decide to start working on the project
  • April 28th, devkits arrive
  • May 8th, schematic largely complete, work starts on PCB layout
  • June 14th, order sent to CM
  • ~July 6th, CM ships order to me (to California, then hand carried to me by a coworker)
  • early August, boards arrive from California
  • Somewhere here I try, and fail, to reflow a modified connector onto a board
  • October 13th, California cowoker helps to (successfully) reflow a USB-C connector onto a board for testing
  • January 6th 2017, finally got around to reinforce the connector with epoxy and started testing, try loading firmware but no dice
  • January 10th, redo firmware, it works, test on DC load, then modify a ThinkPad-slim adapater and test on a real ThinkPad
  • January 25/26th, fixed USB-C connector footprint, made one more minor tweak, sent order for rev2 to CM, then some back & forth over some tolerance issues they're now stricter on.


1: There's a previous variant of USB-PD that works on the older A/B connector, but, as far as I'm aware, was never implemented in any notable products.

Tim ConnorsNo trains for the corporatocracy

Sigh, look, I know we don't actually live in a democracy (but a corporatocracy instead), and I should never expect the relevant ministers to care about my meek little protestations otherwise, but I keep writing these letters to ministers for transport anyway, under the vague hope that it might remind them that they're ministers for transport, and not just roads.


Dear Transport Minister, Terry Mulder,

I encourage you and your fellow ministers to read this article
("Tracking the cost", The Age, June 13 2009) from 2009, back when the
Liberals claimed to have a very different attitude, and when
circumstances seemed to mirror the current time:
http://www.theage.com.au/national/tracking-the-cost-20090612-c67m.html

The eventual costs of building the first extensions to the Melbourne
public transport system in 80 years eventually blew out from $8M to
$500M over the short life of the South Morang project; despite being a
much smaller project than the entire rail lines built cheaper by
cities such as Perth in recent years.

The increased cost is explained away as a safety requirement - it
being so important to now start building grade separated lines rather
than level crossings regardless of circumstances. Perceived safety
trumps real safety (I'd much rather be in a train than suffer from one
of the 300 Victorian deaths on the roads each year), but more sinister
is that because of this inflated expense, we'll probably never see
another rail line like this built at all in Melbourne (although we'll
build at public expense a wonderful road tunnel that no-one but
Lindsay Fox will use at more than 10 times the cost, though).

I suspect the real reason for grade separation is not safety, but to
cause less inconvenience to car drivers stuck for 30 seconds at these
minor crossings. Since the delays at level crossings are a roads
problem, and collisions of errant motorists with trains at level
crossings is a roads problem, and the South Morang railway reservation
existed far before any of the roads were put in place, I'm wondering
whether you can answer why the blowout in costs of construction of
train lines comes out of the public transport budget, and not at the
expense of what causes these problems in the first place - the roads?
These train lines become harder to build because of an artificial cost
inflation caused by something that will be less of a problem if only
we could built more rail lines and actually improve the Melbourne
public transport system and make it attractive to use, for once (we've
been waiting for 80 years).


Yours sincerely,


And a little while later, the reply!

Tim ConnorsYarra trail pontoon closures

I do have to admit, I had some fun writing this one:

Dear Transport Minister, Terry Mulder (Denis Napthine, Local MP Ted Baillieu, Ryan Smith MP responsible for Parks Victoria, Parks Victoria itself, and Bicycle Victoria CCed),

I am writing about the sudden closure of the Main Yarra bicycle trail around Punt Road. The floating sections of the trail have been closed for the foreseeable future because of some over-zealous lawyer at Parks Victoria who has decided that careless riders might injure themselves on the rare occasion when the pontoon is both icy, and resting on the bottom of the Yarra at very low tides, sloping sideways at a minor angle. The trail has been closed before Parks Victoria have even planned for how they're going to rectify the problem with the pontoons. Instead, the lawyers have forced riders to take to parallel streets such as Swan St (which I took tonight in the rain, negotiating the thin strip between parked cars far enough from their doors being flung out illegally by careless drivers, and the wet tram tracks beside them). Obviously, causing riders to take these detours will be very much less safe than just keeping the trail open until a plan is developed, but I can see why Parks Victoria would want to shift the legal burden away from them.

I have no faith that the pontoon will be fixed in the foreseeable future without your intervention, because of past history -- that trail has been partially closed for about 18 months out of the past 3 years due to the very important works on the freeway above (keeping the economy going, as they say, by digging ditches and filling them immediately back up again).

Since we're already wasting $15B on an east-west freeway tunnel that will do absolutely nothing to alleviate traffic congestion because the outbound (Easterly direction) freeway is already at capacity in the afternoon without the extra induced traffic this project will add, I was wondering if you could spare a few million to duplicate the only easterly bicycle trail we have, so that these sorts of incidents don't reoccur and have so much impact on riders in the future.

I do hope that this trail will be fixed in a timely fashion before myself and all other 3000-4000 cyclists who currently use the trail every day resorting to riding through any of your freeway tunnels.

Yours sincerely,

Me

Julien GoodwinOn programming languages

One thing people might be surprised about my job is that although I'm in network operations I write a lot of code, mostly for tools we use to monitor and maintain the network, but I've also had a few features and bug-fixes get into Google-wide (well, eng-wide) internal tools. This has lead me to use a bunch of languages, quite probably more than most Google software engineers.

Languages I've used in the last three months:
  • C++
  • Java
  • Go
  • Python
  • bash
  • Javascript & HTML (Including several templating languages)


In the two years since I started there's also:
  • perl
  • tcsh
  • PHP
  • SLAX (An alernate syntax version of XSLT)


These end up being a fairly unsurprising mix of standard sysadmin, web and systems programmer faire, with the real outliers being Go, the new c-ish systems language created at Google (several of the people working on the language sit just on the other side of a wall from me), and tcsh & SLAX which come from working with Juniper's JunOS which is built on FreeBSD with an XML-based configuration.

April 30, 2013

Julien GoodwinWhy I care about the NBN

First of all, yes I'm a general Greens / Labour supporter so it's not surprising that I like the NBN. I work in a tech field (specifically datacomms) that also generally supports the NBN. I have plenty of reasons to support the NBN from those, but here's the "how it affects me" ones.

I live in inner-city Sydney, specifically Ultimo, literally in the afternoon shadow of (probably) the most wired building in the country, the GlobalSwitch datacenter, yet on a bad day I get 1Mb or so through my Internet connection.

I do have two basic options for a home Internet connection where I live, both through Telstra's infrastructure, either their HFC cable network, or classic copper. As Telstra (last time I tried) were unable to sell a real business-class service on HFC I use ADSL, and since I consider IPv6 support a requirement, I use Internode (there's other reasons I use them as well, but IPv6 sadly is still hard to get from other providers). Due to the location of my apartment 3/4g services aren't an option even if they were fast enough (or affordable).

Sadly the copper in Ultimo is in a sad state with high cross-talk and attenuation. I suspect this is likely due to passing underground through Wentworth Park[1] which is only a meter or two above sea level so water damage is highly likely.

Even on a good day I only barely sustain ~8Mb down, ~1Mb up, with no disconnects, on a bad day it can be as low as 1Mb down, with multiple disconnects per hour.

It's the last point I particularly care about, regular disconnects make the service unreliable and are the aspect that is most irritating.

Speed, although people often want it is of limited value to me, once I can do ~20Mb down and ~5Mb up that's enough for me, handles file uploads fast enough and offers a nice buffer for video conferencing (yes I really do join video conferences from home). I suspect I will subscribe to a 50/20 plan if/when NBN is available in my area. In theory NBNco should have commenced construction in the Pyrmont/Glebe/Ultimo/Haymarket area this month (per their map), but I'm not aware of anyone who has been contacted to confirm this.

Because I'm in an apartment complex it's likely that the coalition's plan would have a node in the basement (there's already powered HFC amps in the basement car parks so it wouldn't be unprecedented), this matches some versions of the NBN plan, although the current plan (last I saw) is fibre to each apartment. Once a node is within a building cable damage due to water is unlikely and I'd probably be able to sustain a decent service, but if I ever moved to a townhouse then I'd be back to potentially dodgy underground cable.

I don't believe forcing Telstra & Optus to convert their HFC networks into wholesale capable networks is a sensible idea for a variety of reasons, the two major being would they still be able to send TV, and the need to split the HFC segments into much smaller sections to be able to sustain throughput. Even with the current low take-up rate of cable Internet I know many people in Melbourne who find their usable throughput massively degrades at peak times, something that would almost certainly get worse, not better, if HFC became the sole method of high speed Internet in a region.

I also still maintain my server and Internet service at my old place in Melbourne, and will get at least 50/20 there, should it ever be launched, when I first got ADSL2+ service I managed to sustain 24/2 but now only 12/1, presumably due to degrading lines, which makes me wonder about how fast and reliable a VDSL based FTTN would actually be.

1: The only real alternate path would add a kilometre or more of cable to avoid that low lying area.

Tim Connors

Oh well, if The Age aren't going to publish my Thatcher rant, I will:

Jan White (
Letters, 11 Apr) is heavily misguided if she believes that Thatcher was one of Britain's greatest leaders. For whom? By any metric 70% of Brits cared about, she was one of the worst. Any harmony, strength of character and respect Brits may be missing now would be due to her having nearly destroyed everything about British society with her Thatchernomics. Her funeral should be privatised and definitely not funded by the state as it is going to be. Instead, it could be funded by the long queue of people who want to dance on her grave.

Tim ConnorsRagin' on the road

Since The Age didn't publish my letter, my 3 readers ought to see it anyway:


Reynah Tang of the Law Institute of Victoria says that road rage offences shouldn't necessarily lead to loss of licence ("Offenders risk losing their licence", The Age, Mar 21) . He misses the point -- a vehicle is a weapon. Road ragers demonstrably do not have enough self control to drive. They have already lost their temper when in control of such a weapon, so they must never be given a licence to use that weapon again (the weapon should also be forfeited). The same is presumably true of gun murderers after their initial jail time (which road ragers rarely are given). RACV's Brian Negus also doesn't appear to realise that a driving license is a privilege, not an automatic right. You can still have all your necessary mobility without your car - it's not a human rights issue.


It was less than 200 words even dammit! But because the editor didn't check the basic arithmetic in a previous day's letter, they had to publish someone's correction.

Ben McGinnesFixed it

I've fixed the horrible errors that were sending my tweets here, it only took a few hours.

To do that I've had to disable cross-posting and it looks like it won't even work manually, so my updates will likely only occur on my own domain.

Details of the changes are here. They include better response times for my domain and no more Twitter posts on the main page, which should please those of you who hate that. Apparently that's a lot of people, but since I hate being inundated with FarceBook's crap I guess it evens out.

The syndicated feed for my site around here somewhere will get everything, but there's only one subscriber to that (last time I checked) and she's smart enough to decide how she wants to deal with that.

This gorgeous photo of The Queen in Melbourne on the Royal Tram made me smile this morning.

I've long been a proponent of an Australian Republic - but the populist hysteria of politicians, this photo, and the Kingdom of the Netherlands is actually making me rethink that position.

At least for today.  Long may she reign over us.

THE law does treat race differently: it is not unlawful to publish an article that insults, offends, humiliates or intimidates old people, for instance, or women, or disabled people. Professor Joseph, director of the Castan Centre for Human Rights Law at Monash University, said in principle ''humiliate and intimidate'' could be extended to other anti-discrimination laws. But historically, racial and religious discrimination is treated more seriously because of the perceived potential for greater public order problems and violence.

Ahaaa. Now I get it! We've been doing it wrong. 

Racial villification is against the law because it might be more likely to lead to violence than villifying women, the elderly or the disabled.

Interesting debates and articles about free speech and discrimination are bobbing up and down in the flotsam and jetsam of the Bolt decision. Much of it seems to hinge on some kind of legal see-saw around notions of a bad law about bad words.

I've always been a proponent of the sticks and stones philosophy.  For those not familiar, it's the principle behind a children's nursery rhyme.

Sticks and Stones may break my bones
But  words will never hurt me

But I'm increasingly disturbed by the hateful culture of online comment.  I am a very strong proponent of the human right to free expression, and abhor censorship, but I'm seriously sick of "My right to free speech" being used as the ultimate excuse for people using words to denigrate, humiliate, intimidate, belittle and attack others, particularly women.

We should defend a right to free speech, but condemn hate speech when ever and where ever we see it.  Maybe we actually need to get violent to make this stop? Surely not.

The Qantas Pilot Safety culture is something worth fighting to protect. I read Malcolm Gladwell's Outliers whilst on board a Qantas flight recently. While Qantas itself isn't mentioned in the book, a footnote listed Australia as having the 2nd lowest Pilot Power-Distance Index (PDI) in the world. New Zealand had the lowest. The entire chapter "The Ethnic Theory of Plane Crashes" is the strongest argument I've seen which explains the Qantas safety record. The experience of pilots and relationships amongst the entire air crew is a crucial differentiating factor. Other airlines work hard to develop this culture, often needing to work against their own cultural patterns to achieve it. At Qantas, and likely at other Australian airlines too, this culture is the norm.

I want Australian Qantas Pilots flying Qantas planes. I'd like an Australian in charge too.

linux.conf.au ballarat 2012

I am right now, at this very minute, registering for linux.conf.au in Ballarat in January. Creating my planet feed. Yep. Uhuh.

I reckon the "book a bus" feature of rego is pretty damn cool.  I won't be using it, because I'll be driving up from Melbourne. Serious kudos to the Ballarat team. Also nice to see they'll add busses from Avalon airport as well as from Tullamarine airport if there's demand.

Too cool.
