Dear Santa, thank you for the dolls and pencils and the fish. It's Easter now, so I hope I didn't wake you but... honest, it is an emergency. There's a crack in my wall. Aunt Sharon says it's just an ordinary crack, but I know its not cause at night there's voices so... please please can you send someone to fix it? Or a policeman, or... Back in a moment. Thank you Santa.

Index and Railgun have shipped, ETA Wednesday. This makes for a lot of computers sitting around, so I'm also going to pick up a new 802.11ac router so that all my things can talk to each other.
Google fixed that stupid URL-mangling feature. I updated to the latest Chrome yesterday, and it works properly again.
Google being Google, they're also cancelling Inbox and forcing people to switch to an updated version of Gmail instead. The updated version of Gmail is not good.

After waiting nine years for a connection date, then six months for the connection date to arrive, then ten weeks for any updates after the connection date passed unconnected, NBNCo now informs me that there is "work to be done" and it will take another six to twelve months to connect me.
The connection point is so close that I could stand at my kitchen window and hit it with a medium-sized dog if the wind was right. Six to twelve months my arse.
In happier news, I found the product page for the laptop HP upgraded me to because the one I ordered was out of stock. (HP have an infinite number of different product codes and it's hard to find the exact details sometimes. That's how infinity works.)
It's the top-of-the-line maxed-out version with a 1TB SSD, and I'm getting two of them. Whee! And my order has passed out of processing and into production, so it looks like it's all happening this time. Which is good, because that model is now also out of stock.
Tomorrow, I'll get hit by a comet. But that's tomorrow.
It has a quad-core 8th generation Intel CPU, 13.3" FHD display, and a multiplicity of ports - not just USB-C but full-size USB-A, wired Ethernet, HDMI, and even VGA. In tablet mode it offers 8 hours of battery life, but the keyboard has its own battery (partly just to balance the weight) giving a total of 14 to 15 hours.
And it even has PgUp/PgDn/Home/End keys, though the arrangement is a bit haphazard, similar to Lenovo's smaller laptops.
Speaking of which, if you're in Australia and looking for a general-purpose laptop, Lenovo has been messing about with pricing on their ThinkPad E family again. With a quad-core Ryzen 2700U, 16GB RAM, 512GB SSD, and 1TB disk drive, the E485 currently works out to A$1374, which is a great price. If I hadn't just bought Index and Railgun I'd be strongly tempted.
The closest Intel model is A$1846, which is less attractive. By about A$472.
This is a known problem, and it can even be done with desktops and servers if you are very quick, but it's probably around #4718 on the list of security issues you should worry about.

The "cracking all encrypted laptops" thing was a real groaner. I'm sure one of our execs will read it and send a panicky email to my boss asking how we're going to deal with this crisis.

HP just called and uncancelled my order and even offered a free upgrade because their online store was showing stock they didn't really have. Unfuck.
I'm not certain exactly what I'll be getting, but it will either be a slightly newer model with the same specs, or the 1TB model from the same range, depending on availability.
So minus five points for inventory management, but plus twenty for customer service.
Based on how long it's taking 10GbE to roll out, this will arrive on desktops shortly after the heat death of the next universe after our own.
Google doubled down on stupid but decided against tripling down. The next patch release for Chrome no longer hides www. and m. in URLs.

HP sucks. 8 years ago I bought a Pavilion laptop, and it worked fine for 8 months, then wouldn't power on (the caps lock LED would flash three times, which indicates a CPU failure). Over the next 4 months, I returned it to them three times, and they claimed to have replaced the motherboard twice and the CPU twice, but it would quit again within days. They ran the clock out on my warranty, and when I called them the third time to return it again, I asked them at what point could we declare it a lemon and replace it, and they said I had to keep sending it back. Then the warranty ran out and I wasn't going to send them another couple hundred bucks to string me along another year.
Moral: don't by HP.

That kinda sucks. I did pay an extra $59 for two-year on-site service, which seemed well worth it.
Most of my hardware purchases the last few years have worked as expected, without problems, with some minor exceptions like the Bluetooth range on my keyboard. Oh, and don't buy Dell speakers. They're rubbish. Dell computers, just fine. Speakers, crap.

It's a good / bad / ugly kind of day, so let's get to it!
Good: That HP Spectre X2 sale for A$1275 (which works out to US$825 plus tax) is still on. While I was waiting for some funds to arrive (I sold one of my domain names - not one of the mee.* flotilla, another one - for a quite useful amount of money) it came into stock for next-day delivery, went to "hurry, limited stock" and sold out. But they have more on the way, I just need to wait a couple of weeks.
Remember me?
The specs again: Intel Core i7 7560U (2 core / 4 thread, 2.4GHz base, 3.8GHz peak); 16GB LPDDR3 1866MHz RAM, 512GB NVMe SSD, and a 3000x2000 12.3" display. Two USB-C ports supporting charging and DisplayPort 1.2 output, but not Thunderbolt; MicroSD; and headphone jack. Keyboard included in the price but not sure about the pen, though it works with any Windows Ink pen including HP's own and Wacom's Bamboo Ink. The CPU includes Iris Plus graphics, so double the usual number of graphics cores and a 64MB L4 cache.
This sale is Australia only, but given that the retail price of the next model down is over A$3000 it's a crazy bargain on a great computer. It has a couple of limitations: It's dual core rather than quad core, and it doesn't have all-day battery life like, say, a MacBook. But at about 70% off I don't care one iota. And it has USB-C charging so you should be able to use an external battery pack.
I bought two. Because I'm an idiot. And because I had some completely unexpected funds come in at exactly the right time. (Well, almost exactly the right time. If the funds had cleared two days earlier I would have had these for a week already.)
And because at this price they're cheaper than buying an Intel NUC. Or to put it another way, a single Microsoft Surface Pro with half the memory and half the storage costs within $100 of two of these. And then the Surface keyboard costs extra. So I was... Slightly irked when they ran out, and I'm rather pleased that they came back into stock.
Assuming they don't run out of stock again and I get both and they work as expected, they will be named Index and Railgun.
Do I actually need two of these? Nyaa.... Do I want two of these, though? Hell yes.
Update: Out of stock again already. Double extra out of stock, in fact; the store page has been hidden and there's no buy button if you kept the link. Hope I got my order in in time.
Not much excitement as these are all variants of Ryzen 2, not a new die. But the 45W 8-core 2700E and 6-core 2600E are interesting. The 2700E is barely slower than my Ryzen 1700 but at 45W rather than 65W. Which means that (a) you could see 8 core laptops with sensible power budgets, and (b) AMD could turn out a 90W 16 core part any time they wanted to. (In fact they have announced exactly that but for embedded servers rather than desktops.)
If you have an AMD Threadripper 2990WX Death Metal system and an Nvidia graphics card you probably haven't been too happy lately. Fortunately, you don't. Also fortunately Nvidia have fixed their drivers. (PCPer)

It looks like M$ is going to start trying to manage low storage space on your systems by moving files to OneDrive and leaving only a placeholder on your local system, which will pull the file back down when you attempt to access. This sounds like a Charlie Foxtrot in the making to me and makes me especially glad my migration path off of Win7 was to Linux.

Reading the official blog announcement, the MS "storage sense" auto-cleanup seems to be at least three different things: 1) the existing disk cleanup tool, 2) an LRU cache for OneDrive ("dehydration"), 3) auto-delete old Downloads (off by default even if you enable all the rest).
The problem is that there are some unclear pronoun references in the blog entry that can be read as if it moves files from <i>anywhere</i> on your drive to the online-only OneDrive cache, and I don't think that's what they meant.

There's nothing particularly fancy about these, although they're filled with helium so they make amusing squeaky noises. Oh, and peak transfer rate is over 260MB per second, which is pretty damn fast for a disk drive.
I still have a couple of 14GB IBM disk drives in my Sun Ultra 5. (The Ultra 5 only has one 3.5" bay, but it has an empty floppy bay, so...)
This is a big deal. TSMC is riding high on being the fab for Apple's iPhone chips, and has the funds to invest in new facilities. Intel meanwhile is suffering through a four-year delay in getting their 10nm node into production.
Fun fact: That Ryzen desktop chip you're using? It contains four 10GbE network controllers. Which you can't use because they're not wired up in Ryzen, but they are in Epyc.
They decided to hide what they call "trivial subdomains" like www and m (for mobile). But they fucked this up, so that if, for example, you owned www.com, google.www.com would show up as google.com, with the green padlock SSL security indicator and everything.
Speaking of which, our new server naturally has the L1FT bug. You'd either need a very old server, or an AMD Epyc system, to be free from that on X86. It means if I want to play it safe I'll either need to disable hyperthreading (losing about 20% performance) or leave the remaining CPanel instances on their own server. Though KVM might work too, I should check that.
Also looking at going with native ZFS and RAIDZ rather than the RAID-5 / LVM lashup I have at the moment.
Also, ZFS offers native comprssion (LZ4 by default) and optional deduplication, as well as the neat snapshots and filesystem replication and such. InnoDB also supports compression, but last I checked it had a single compression thread making it a bottleneck on write-intensive workloads; on ZFS it's multi-threaded.
This article examines some ZFS features, comparing performance of RAIDZ, RAIDZ2, and RAIDZ3 (equivalent to RAID-5, RAID-6, and RAID-7) with and without compression. It's mostly concerned with disk drives but SSDs are also examined.
I've picked up a couple of books on ZFS as bedtime reading.
Also want to reinstall so I can do a clean install of LXD 3.4 in place of 3.0. The ability to do local backups of containers (as opposed to snapshots or migrations) was introduced in 3.1 with the export command; Ubuntu 18.04 ships with 3.0. I really want to be able to easily take local backups. The export command is doubly nice because you can export a container complete with snapshots, so you can snapshot hourly and do an off-site backup daily, and if you have a disaster and need to pull the off-site backup and restore to an earlier point in time, you can.
Update: Now getting 40K random write IOPS with queue depth 16. I was getting around 18K on RAID-5, so this is a very clear win. The secret is to tune the record size on each dataset - 4K or 16K for databases, 128K for file and application servers. The default is 128K, which is fine for most workloads on spinning disks but is much too large for databases on SSDs.
The culprit this time is Dr. Unarchiver, allegedly by Trend Micro. I'm not sure if it's a Trend Micro app, a third-party app sold by Trend Micro on the app store, or if it was sold by a fake account on the App Store. In any case, it's gone now.
The benchmark scores are real, but not reflective. The phone is diddled to detect that a benchmark is being run and go into a high-power high-performance mode to inflate scores.

I was writing up an introduction to LXC / LXD and ZFS but the formatting got messed up so I've hidden it for the moment. It will show up later in the week.
But they also note that they maintain 600,000 concurrent websocket connections. That is significant, and not something I'd want to do on my usual nice clean threaded architecture.
This article about web bloat is three years old but things haven't improved. It points to a news article about web bloat that was 18MB for a single page. I clocked it at 1.2MB with Adblock enabled, and 22MB without - and page elements were still loading after two minutes.
Don't go there without Adblock. Seriously.
When Eric S. Raymond says non-discrimination he means non-discrimination, not today's trendy interpretation of discrimination, but only against people I don't like.
He discusses an open-source project that had changed its license to block use by fifteen major companies. The project is hosted for free on GitHub because it is open source. The license change would mean it no longer qualified as such.
And one of the companies they banned was Microsoft.... Which owns GitHub.
It looks like the change was reverted after it blew up in their faces.
It is, incidentally, a project for managing JavaScript projects. JavaScript is a head injury disguised as a programming language; everyone who works with it for any length of time either starts out or ends up with brain damage.

"It looks like the change was reverted after it blew up in their faces."
The guy who made the change was booted from the project, although not necessarily because sanity prevailed as such (he violated some code of conduct of the project, apparently). He'd made the same change to another project, and it got reverted as well.

What was even more troublesome was that the fellow who was PNGed by the project was not the only poster on GitHub who thought it was a swell idea to push their personal politics into technology. The chorus of 'Agree!' was scarier.
That project was just itching for the moment Microsoft decided to make an example of them by landing a giant boot heel into them - trying to screw with a company using their property is generally not a good idea.

It's a 49" curved IPS display with a resolution of 5120x1440. That's pretty good, and a big step up from the more typical 3840x1080 for ultrawide monitors, but I'm holding out for 7680x2160. Which is, after all, what I already have.

If you have an old and/or cheap router, or are just unlucky, you'll probably need to buy a new one. Same goes if your phone or tablet has stopped receiving software updates. Computers should update automatically to the new standard when it arrives, unless they're really, really old, in which case they've probably already been hacked.

It's extremely unsafe to ban the requesting entities, though, because then if some of the requests are -legitimate-, and Google ignores them, then Google ends up liable for participating in the infringement (and subject to statutory damages).
The law is a little unbalanced in that Google (should it fail to heed the notice) becomes liable for statutory damages; but the damages for a report not filed "in good faith" are limited to -actual- damages, which are going to be pretty minuscule for any particular instance. So the only way that Google can legally respond would be in aggregate; "hey, you filed a hundred thousand bad notices last year!" But then the other party can turn around and say "we filed eight hundred thousand GOOD ones; if our responses aren't always great, it's just due to the huge scale of your lawbreaking!" That's not a good place for Google to be, legally speaking.
Of course you can say "it's not Google's fault there's all this copyright infringement going on" - after all, the law doesn't give them any responsibility to stop it, just to respond to the DMCA requests properly. But if they go in front of a judge and say "we can't comply with the law due to the scale of the problem," there's a non-zero chance the judge will come back with "it's your responsibility to ameliorate that by reducing the number of infringing uses yourselves!" And suddenly Youtube has a requirement to screen for stuff affirmatively, and the financials for running it go right out the window...

A lot of the take down craziness is being driven by technology outpacing both law and industries' ability to adapt to change. Much of our content distribution industry is still as outdated as buggy-whip manufacturers in their thinking and desperate for the 'good old days' when they were robber barons of content.
Bluntly I think we're (United States) going to need to go back to something more in line with the 'limited Times' portion of the Copyright Clause of the US Constitution. I suspect, given the much easier modes of publication today compared to the 1700s, it'll ultimately end up somewhere around 10 years +/- 5 years. Opening up all this material to the public domain and restraining the time the works need to be protected would rip away much of the incentive to invest in overly aggressive copyright protections.

Samsung is aiming to have its 3nm process in risk production by 2020. Risk production is the first runs of commercially useful chips to come off a new fabrication process; they have more variability and defects than later chips. (Anandtech)
Samsung also announced that their ultra-low-power 8nm process will come on line later this year.
The $55 chip is a 2 core / 4 thread part running at 3.2GHz, with 3 Vega CUs (192 shaders) and a 35W TDP. That's great for a media center system, but for desktop use (and certainly for gaming) you're better off spending $99 for a 4 core / 8 CU Ryzen 2200G.
QNAP's TS-332X NAS is a weird beast. It has three 3.5" drive bays, three M.2 slots - but SATA only - and three ethernet ports, two 1GBase-T and one 10Gbit SFP+. (Serve the Home)
I don't know who it's for, exactly. The home market isn't running SFP+ cables and the device is far too small for businesses that would. And it can't use NVMe drives at all - though three SATA SSDs are enough to saturate a 10Gbit link anyway.

I cancelled the server I ordered by mistake and the new server is up and running. It has the same basic specs with two differences: Instead of 8 x 1TB disk drives on the old server (I misread the specs and thought it was SSDs) it has 6 x 2TB SSDs. Really real SSDs this time; I've tested the array at 300,000 IOPS, the equivalent of 2500 regular 7200 RPM disk drives.
And instead of 200TB of monthly bandwidth, it's 1Gbit unmetered. Which doesn't actually make much difference, because 200TB is close to saturating 1Gbit outbound and I don't do much inbound traffic.
Oh, and it's software RAID rather than hardware.
Reinstalling it now, configuring RAID-5 and LVM, so I can take consistent snapshots of the entire server without having to worry about managing clean database dumps of MySQL and MongoDB and Elasticsearch and and and...
Then I install KVM and LXC, then I start migrating systems across into their own neat little virtualised containers.
Update 1: Manually configured RAID-1 for boot and RAID-5 for LVM, splotted swap volumes everywhere, and installing Ubuntu 18.04.1 right now. The auto-install script unhelpfully assigns 100% of the default volume group to / meaning you have no room left to take snapshots. I hope I got it right, but at least the partitioning is right so it will be a lot easier if I have to reinstall again.
Update 2: The secret is to use the autoinstall to bring up the server quickly, then use fdisk to create your custom partitioning scheme, then use the Ubuntu expert install mode to install on those partitions. Much much quicker than fiddling about with the partitioning tool in the installer.
Also, don't install to a huge software RAID-5 or 6 array, even on fast SSDs. It takes at least five times longer than normal because the sync will be running the entire time. Create a RAID-1 array for the OS and you'll be done that much faster.
Update 3: Whee! That was so much faster. Let's see if the network config works this time...
Update 4: Yep, that worked perfectly.
Update 5: Well, I messed that up slightly. I think I'll just go with LXC here, and leave KVM alone.
