  • If you put the names of your LXD containers in your hosts file or internal DNS, and match them up to LXD-managed IPs, LXD will actually do the right thing and assign those IPs, rather than its astoundingly unhelpful default behaviour of pulling an IP address out of its ass each time.

    If I'd known that a year ago it would have saved me, well, two or three hours, to be honest.

  • It really does look like the Ryzen 4700U will have eight cores.  (Tom's Hardware)

    The problem is that it's a laptop part and supposed to run at 15W.  That's not a lot of power to run eight cores and 832 graphics shaders.

  • The Intel 665p is a better version of the 660p, but is it better enough to fend off cheap DRAMless TLC NVMe SSDs?  (Tom's Hardware)

    The 665p is hampered by having only 2 PCIe lanes, meaning it can never break the 2GB per second barrier.  On the plus side, the 665p improves direct write performance (once the cache is full) by 50% over its predecessor.

  • Nitter is an alternative front-end to Twitter.  (GitHub)

    It acts as a proxy server - your browser talks to your Nitter node, and Nitter talks to the Twitter API.

    It uses no JavaScript.  Not on the server, and not in the browser.  That's pretty impressive.

    And it's written in Nim, the Python-like compiled language I've mentioned a couple of times when talking about Crystal.

  • Why Nitter?  Perhaps because the modern web is becoming an unusable, user-hostile wasteland.  (Abid Omar)

    Twitter is far from the worst culprit in that respect.  Well, the UI and API anyway, the content is another question.

  • Design your web pages to last.  (Jeff Huang)

    A good list:

    1. Use vanilla HTML and CSS.  If you need JavaScript, use it; if you don't need it, don't.

    2. Don't minimise.  Your page will get compressed automatically by the web server, so minimisation makes the files unreadable while only saving a few percent.

    3. Just have one great big page.  Uh.  Not so sure about that one.

    4. Don't hotlink.  That includes sites like CDNJS, convenient as they are.  At least make sure you have a copy of anything you load from another source.

    5. Don't use fancy webfonts.  Or if you do, put them on your own server.

    6. Minify your SVG.  Wait, what?  Use WebP, an image format that works with about 20% of apps on a good day.  Um, no.  

      Rule 6: There is no rule 6.

      But don't embed huge PNG files right in the page.

    7. Use a free monitoring service to tell you when your hosting provider has disappeared and your site is unrecoverable.

      So you can spend your weekend trying to extract it from archive.org.

  • Things done fast.  (Patrick Collison)

    And things done not fast.  San Francisco has been building a bus lane for 20 years.  The Alaska Highway took less than eight months.

  • Apple is working on top secret satellites.  (Bloomberg)

    I think people will work out what's going on when they launch the things into space on a huge fucking rocket.

  • I missed this one before: Data for 1.2 BILLION people was left in an unsecured Elasticsearch server connected directly to the internet.  (WCCFTech)

    Elasticsearch, until recently, had no security at all in the open source version.  I mean, sure, MongoDB installs by default without a password configured, but it does nag you to set a password.

    Elasticsearch didn't even have passwords in the free version.

  • Now data collected from million Facebook accounts by a third party has been found in another unsecured Elasticsearch server.  (WCCFTech)

    To be clear: This is not a server operated by Facebook.  Someone got their hands on the data somehow, put it in Elasticsearch to do, well, whatever, and left it connected to the internet with no password because until recently the free version of Elasticsearch didn't have passwords.

  • San Francisco accidentally banned smartphones.  (TechDirt)

    First worthwhile thing they've done since they burned the place down.

  • The Standard Model may be broken.  (Ars Technica)

    Have they tried turning the Universe off then on again?

1 4700U:  you can undervolt the hell out of Zen/Zen+ and still get close to peak clocks.  I'm not sure about Zen 2:  early on, some reports said people were undervolting chips to ~1.0V and still seeing high clocks, but benchmark performance took a dive.  I haven't seen any more reporting about it since then, though, but I was manually OCing my 1600X via custom P-states, the only way you could on a lot of motherboards, and IIRC I had a 2.2GHz step with something like 0.875V.  A quick search found a Reddit post by someone saying that you can lower the peak current limit on Zen 2 a lot and get fairly small drops in multicore benchmarks and almost no drop in single-core perf.  I guess we'll see how this shakes out, though.  The 4700U will probably wind up with an all-core boost under 4GHz, though.  My 3600X tends to hit around 4.1 all-core.

2 "And they started charging for small crap: Deposit money? There is a small fee"
This seems like the time to get out the torches and pitchforks.

Look, the bureaucracy and moving all that human poop out of the way takes a lot of time.

4 To be fair, it's a lot of poop.

5 I'm really looking forward to seeing the 4700U in action.  With 5nm it would be entirely possible to double everything - 16 cores and 26 CUs - if the power can be kept under control.  If it achieves reasonable speeds at 15W at 7nm, a doubled version should be achievable at 25W at 5nm.

16 core thin-and-light laptops with better than RX590 graphics in 2021?  Maybe.

Apple pies are delicious. But never mind apple pies. What colour is a green orange?
