tyldum commented on Ideal monitor rotation for programmers (2021)   sprocketfox.io/xssfox/202... · Posted by u/AndrewKemendo
bluGill · 2 years ago
Apps and window managers understand full screen. With my wide monitori often want full height, but not full width this needs manual adjustment to work. Windows can sometimes be made full height (tripple click), but this somehow always seems to get the wrong width

That's why I use picture-by-picture (PBP) on my 32" 4K. Two DisplayPort connected to the same computer and control them independent of each other. I also love how my Ubuntu virtual Desktop only rotates the primary screen leaving the other half static.

When needed I can fullscreen across both.

No borders!

Yeah, and their ultimate pricing is bananas.

We're on the premium tier and like some of the security related stuff that's only available in ultimate - but the price jump is so insane it's just not even remotely going to happen.

tyldum · 3 years ago
Since guests are free in ultimate, we could probably go from 150 to 50 licenses. However that requires us to do a cleanup of repo roles and limit who can contribute. We also have a divide between pure developers and IaC users, but can only have one kind of license. It's fragmenting our users, and in order to justify Ultimate we need to force all users on GitLab for everything, even when a team has an alternative they are happy with (like security scans).
tyldum commented on Fast bitset decoding using Intel AVX-512   lemire.me/blog/2022/05/06... · Posted by u/ngaut
zasdffaa · 3 years ago
I've read that the value of avx512 as separate instructions isn't high, and this kind of confirms it - a 20% speedup[1] over the next best (ns/value) isn't spectacular and seems to bring a large cost in terms of complexity like dropping the clock (and are there really 512-wide paths on the chip?) and just a bunch of new instructions. Perhaps deep pipelining would have been better based on existing instrructions.

Can anyone with actual hardware experience comment?

[1] Have I got that wrong? Is it 25%

(edited to de-screw formatting)*

I don't have the technical details, but I work in a field moving from FPGAs to CPU and all solutions require AVX512. These are software defined radios. The vendors say there is no other way to make it work on higher bit rates.

Layman speculation—Using exactly this system (it's quite brilliant!) I bet we could use much higher frequencies due to modern electronics, antenna design, and so forth, giving additional precision, and maybe the ability to measure craft attitude. I could also see additional systems (a laser rangefinder...? or whatever) augmenting it without the mass & energy penalty they would have imposed 50 years ago.
tyldum · 3 years ago
As someone who does modern ranging, you are pretty much spot on.

Fewer and fewer do ranging these days, and the few that does only uses it for contingency situations or to validate GPS receivers during launch and early phase.

Maybe a good follow-up post would be to compare the Apollo hardware to modern hardware. It would be nice to see the differences in size, complexity, etc.
tyldum · 3 years ago
It's starting to transition into software defined these days. The antennas themselves are similar size, depending on frequency but the backend systems are now down to a standard server (at least up to 250-ish megasymbols and increasing).

Things like viterbi are designed to be done efficiently in hardware. Doing it in software is limited to CPU core speed. Multi threaded solutions are hard to engineer as the signal is a continuous stream and cannot trivially be split up for parallel processing.

I do grounds stations for a living. Currently building edge clouds to do this at scale where the dishes are placed around the globe.

No OP, but I’m using mailinabox on a linode vps for $5/month. The IP is in a range that doesn’t typically get marked as spam by default, and there are several checkers in place on the admin console to make sure that you’re dotting all of your “i”s and crossing all of your “t”s, from MTA-STS to DNSSEC. I do still run into problems from time to time, but it’s very rare these days.

Mailgun and others also have a free tier for relaying smaller numbers of email.

I've configured Postfix to use it for fallback if I can't deliver directly.

I use Digital Ocean and seem to struggle a bit delivering directly. 60 emails this month had to be delivered through mailgun since direct failed. Their free tier is up to 1250 emails per month.

Many parks do this. It makes a ton of sense. IMO the best system for businesses that need rigid times would be to have separate winter and summer hours or just make the opening time <x> integer hours from sunrise.
tyldum · 3 years ago
Polar area here. So, in the transition from summer to winter the day is shortened about 15-20 minutes each day. And vice versa from winter to summer.

And at some point in the summer, the sun never sets. During winter it never rises...

Time isn't easy on a global scale.

The issue is you order something, your significant other unpacks the thing and disposes the paper which includes the invoice to be paid. Only weeks later you get notified that you did not pay.
tyldum · 4 years ago
Could be different in your country, but here in Norway there wouldn't be an invoice in the box. The whole idea is that payment is totally separate. Email invoice or separate invoice per post, unless you pay immediately when ordering.

The shop you ordered from does not know or care how the transaction is done between you and Klarna.

tyldum commented on Starlink Ground Station Map   google.com/maps/d/u/0/vie... · Posted by u/addflip
supernova87a · 4 years ago
Does anyone have an image of what one of these ground stations looks like? Do they piggyback on some existing antenna shack? Or did they build their own from scratch?

I also wonder whether they considered partnering with AWS Ground Station? https://aws.amazon.com/ground-station/

Or maybe the Starlink constellation's requirements are not amenable to that?

tyldum · 4 years ago
Currently AWS Ground consists of a very small set of sites and antennas, not enough for any constellation. It's also very limited in terms if services.

In Norway it was 3 deaths in 130000 vaccinated if I recall correctly. But yeah, Norway definitely seems like an outlier.
tyldum · 4 years ago
Norway only has 680 dead from covid, so not much tolerance on collateral deaths due to the vaccine. The vaccine has about half of the mortality rate of covid, by raw numbers alone in Norway.

Of course, younger women are more at risk and nurses were the the ones who received most doses. This could explain the outlier as well.
