Tech News

  • Paper launch day for Nvidia's RTX 2000 family.  Cards will actually be available following Talk Like a Pirate Day.  (I don't know why either.)  (AnandTech)

    Despite WCCFTech being WCCFTech, their leaks on these cards were 100% accurate.  Top of the line 2080 Ti will have 4352 shaders and 11GB of 14Gbps GDDR6 memory.

    More interesting (potentially) is that these are the new Turing architecture with Tensor cores for AI processing and a dedicated ray-tracing unit.  When Nvidia talk about huge performance gains, they are talking about these new functions, not about the actual graphics, which look to be only 10-20% faster depending on the card. 

    Also, price increases across the board, so you have that to look forward to.  Though to be fair, these are far cheaper than the recently announced professional versions, and I don't think you'll find the same AI or ray-tracing performance cheaper anywhere.

  • The annual Hot Chips conference is on and one of the first presentations is on Samsung's M3 chip, a high-end fully custom ARM design.  Samsung are working to catch up with Apple here, because Qualcomm are dragging their feet in that department.  (AnandTech)

  • Apple may release a new MacBook Air and a replacement for the 97-year-old Mac Mini.  Or not.  (Bloomberg, via Tom's Hardware)

  • Shuttle announced this chunky little nugget.  (WCCFTech)
    http://ai.mee.nu/images/ShuttleMcNugget.jpg
    No, I don't know why either.

  • Template languages always end up Turing complete.  The Minx template language is Turing complete, if you really want to do that.  (Well, mostly.  The template engine solves the Halting Problem by nuking your page if your template code issues too many instructions.)

    So either plan for that, or don't implement a template language.

  • There is a new vulnerability that impacts everything.  Unless there isn't or it doesn't.  It gave me a headache and I closed the page, and now I've lost the link.  Just assume you've already been hacked and everything is gone.

Social Media News

  • Turkeys of a feather flock together.  Does that chart stack vertically, or overlap?  Either way, it's bad.  Turkey is responsible for something between 40% and 80% of the censored Twitter accounts worldwide, depending.  (Techdirt)

  • JavaScript client and server apps are vulnerable to regex attacks.  (Bleeping Computer)

    Well, the headline refers to JavaScript, but the real culprit is single-threaded event-driven model for server applications.  We invented multitasking for a reason, you clowns.  All these problems were solved in the early sixties, but nooo, you had to go and reinvent everything.

  • Slow news day, busy work day.  More tomorrow.


Anime News

  • There's a 4K remaster of Cardcaptor Sakura.  I have the remastered 1080p Blu-Ray edition of Bubblegum Crisis, and it looks great, but this is the first I've heard of an anime series going 4K.  It was done on 35mm film, so the resolution is there, but the detail isn't.  I don't know if they've touched up the art; they didn't do that for the El Hazard re-release, which does look great, but the resolution allows you to see all the flaws in the original hand-painted cels.

    Update: Ah, it looks like they remastered it in 4K but released it in 1080p.  That makes sense - there's no point in remastering it twice, there's not point in going higher than 4K, and there's no much point in releasing it at higher than 1080p right now.

Videos of the Day

The opening credit sequence for Erased (Boku Dake ga Inai Machi) is one of my favourite in all of anime.  It tells you everything that will happen in the show without spoiling it; only after watching the show can you see the layers of significance in each frame.

Oh, and the song is good too.


Some guy in his mom's basement (seriously, that's the name of his YouTube channel) analyses it much more deeply than I ever did and shows just how much attention to detail goes into the creation of a good opening sequence.

SPOILER WARNING: The credits above are safe to watch, but DO NOT watch the analysis below if you haven't seen the show already.  (And if you haven't seen Erased, watch it, it's great.)


Also, I never noticed there were two versions of this.  Totally missed it.  And the difference is hugely significant.

  • The T2 chip in the new MacBook Pro crashes randomly.
    The T2 chip controls the touchbar.  Oh, and also storage encryption.  So if it stops working it bricks your laptop.  It does automatically reboot after crashes, but it would be kind of nice if it didn't crash in the first place.

    Here's a thirty-seven page forum thread from users whose $4800 MacBooks crashed with related errors.  (MacRumors)

  • If you read AnandTech's Threadripperoo review before, well, they've updated it slightly.  Like, another 12,000 words.  (AnandTech)

  • The wonderful thing about standards, is standards are wonderful things.  Wait, no, that's tiggers.  Meanwhile here's 13 next-generation form factors for high density NVMe SSDs.  (AnandTech)

  • Testing AMD's StoreMI with Intel's Optane produces terrible results.  Credit to Linus for persisting and finding out why - not a fault specifically in either product, but StoreMI likes to cache everything, and a 32GB Optane drive isn't big enough to produce good results on huge game files.  Giving it 256GB of SSD for the cache fixed everything.



    But warning: Once you have used a drive under StoreMI you have to hard reformat it before you can use it anywhere else.

    Oh, wait, now you don't need to watch the video.  Oops.

  • RAM prices may drop 25% next year. (Tom's Hardware)

    Well, it's a start, but it would still leave prices at more than twice their low point five years ago.

  • The Protectli FW4A is a four-port firewall appliance for small(ish) offices. Install your own OS - there are various BSD and Linux distributions designed for exactly this. All the network controllers are Intel, so it should be compatible with anything and everything. (ServeTheHome)

    The thing I noted is that it has a VGA port. That's pretty much essential because the alternative is rigging a serial connection somehow. But I don't have anything on my desk that takes VGA in - I'd have to dig an old monitor out of the spare room.

    Its big brother (sister?) the FW6A has six ports (fairly obvious) and includes HDMI. It's not much more expensive - $419 vs $349 including memory and storage, and includes a lot more USB ports - and you don't need to dumpster dive for a monitor to set it up. Go for that one. Or just air gap your coworkers, that's pretty good too.

  • Princess Evolution RaaS is not a poorly translated FM Towns game from 1993. Well, it might be that too, who knows. But the gameplay in the 2018 version sucks. (Bleeping Computer)

  • AMD is now shipping their 35W low-power desktop APUs, the 2200GE and 2400GE. These have the same specs as the 2200G and 2400G except for clock speed. Capped at 35W instead of 65W they will throttle under load much sooner. (FanlessTech)

    AMD is also believed to be planning a 45W high-power laptop chip to complement their existing 25W laptop parts. And when I say "believed to be planning" I mean "everything except the price and ship date has been leaked".

Found A New Editor!

I'll see if I can deploy it here for some live testing.  I will definitely use it for the new system.

It's called Redactor.  The other one I'm looking at is called Froala.  Froala has some neat tricks, but it's a bit on the expensive side.  Redactor is 60% cheaper, plus I bought a license for an earlier version years ago, so I can upgrade to the latest version for half price.

Redactor has fewer tricks but has a nice API for adding extensions, so I can tie it into my new API.  

For example, if you start typing an @name, I can look up your friends list and show you the matching names and when you select one, automatically turn it into a link.

Also: Autosave.

Update: Bought a Pro license for Redactor.  I got a Basic license all the way back in 2012 to try it out, but didn't switch at the time.  They've done a whole bunch of updates since then.

  • Microsoft's Cortana exposed as double-agent.  (Tom's Hardware)

    If you had certain "skills" enabled, locking your computer didn't really do much, because Cortana is still active.  This is fixed in the most recent Windows 10 update, which is why it's being publicly announced now.

    Normally I suggest taking anything from WCCFTech with a pound of salt, but this is so unexciting that it's probably entirely accurate.

    One caveat: It has 16 DIMM slots.  It has 12 memory channels.  16 is not divisible by 12.  (Apple shipped a Mac Pro with a similar arrangement, years ago.)

  • After noting that AMD's 32 core 2990WX runs dramatically faster on Linux than on Windows 10, Phoronix went back and ran those tests under Windows Server as well, both 2016 and the 2019 preview.

    Windows Server was generally no better and sometimes significantly worse.  (Phoronix)

    Linux has the benefit here of having been ported to hundreds of weird architectures over the years.  The unbalanced memory paths of the 2990WX are nothing compared to some of the crazy shit out there.

Chip Diagram of the Day

AMD's Zeppelin die has 32 lanes of PCIe, but only 24 are available in Ryzen CPUs.  Where did the rest go?  This diagram from Wikichip explains it.

https://ai.mee.nu/images/ZeppelineDie.png?size=720x&q=95

If you look at this diagram, the chip doesn't just have 8 cores, 20MB cache, and 32 PCIe lanes.  It also has four ethernet ports, four USB 3 ports, and eight SATA ports.  All of those - a total of 48 potential connectors - go into a switch and then are routed out to 32 multi-function I/O lanes.  

AMD offers chipsetless chipsets for Ryzen - the A300, B300, and X300.  These low-cost parts have no I/O features at all, and instead rely on the USB and SATA ports built in to the CPU.  That ties up pins that would otherwise be available for PCIe, leaving a maximum of 24 total PCIe lanes available.  All the functionality is there, but you run out of CPU pins trying to connect to it all at the same time.

(Those 12G PHYs are just what you think - they run at up to 12Gbps, 50% faster than PCIe 3.0 and twice as fast as SATA.  This speed is used for socket interconnect on dual CPU EPYC servers, but not on desktop Ryzen parts.)

    Pricing for Premium access is $2,899 per month for 250 users. To cover this cost, a third-party app would need to charge over $16 per month to break even.

  • For Intel, it's a new day so there's a new speculative execution vulnerability. This one is called Foreshadow by researchers and L1TF by Intel - Level 1 Terminal Fault because it relates to the level 1 cache permission checking termination logic. (Ars Technica)

    Fortunately I didn't get around to migrating to Digital Ocean just yet. We run VMs for mee.nu - half a dozen of them with more on the way - but on dedicated rather than shared hardware, so this exploit mostly doesn't apply. (Digital Ocean)

    An interesting point is that Intel has already provided a patch that largely resolves the problem, unless you are running hyperthreading. I'm not sure about other cloud providers, but my understanding is that Amazon run customer-specific CPUs with hyperthreading disabled, and have done for years. As core counts increase we may start seeing a trend towards disabling hyperthreading by default - as seen in the upcoming eight core i7 chips. (Or so rumour has it.)

  • Google still tracks your location when you turn off location tracking. Because "don't be evil" got too complicated. (Fudzilla)

  • NVIDIA's new high-end graphics cards are using Samsung's new 16Gb GDDR6 memory. This is another thing that will trickle down to consumer parts fairly quickly. It's 40% faster than the fastest commonly-used GDDR5 memory (14Gbps vs. 10Gbps).

  • Faxes are now haxes. Network-attached multi-function printers too. (The Register)

    If you have an HP multi-function printer on your network, the time to update the firmware is right now. Some of the more recent models apparently update themselves automatically, but it's definitely something to check. You may have a wonderful high-tech firewall that blocks every single thing, but hackers can just dial straight in to your fax machine.

    This sort of thing has been going on for some time, really. There was a story years ago about a company that kept having outbreaks of computer viruses even after patching every single PC and server on the network.

    Turned out the source of the infection was a colour laser printer, which had an internal hard drive for storing fonts and print jobs.... And viruses.

  • PCWorld tested the Threadripper 2990WX just like everyone else (not me) and found something interesting.  Though it trails behind the fastest Intel chips on some tests (because of memory latency, OS scheduling, or something else) that's when you are testing one application at a time.

    They tried running Blender and Cinebench at the same time - and it ran Cinebench as fast as the 18 core Intel i9-7980X running Cinebench alone.  (PCWorld)
