tyldum··on Ideal monitor rotation for programmers (2021)
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!

tyldum··on Why won't Gitlab support monthly billing?
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··on Fast bitset decoding using Intel AVX-512
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.
tyldum··on The digital ranging system that measured the distance to the Apollo spacecraft
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.

tyldum··on The digital ranging system that measured the distance to the Apollo spacecraft
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.

tyldum··on Google destroyed my Play Developer Account and my work for the last 2 years
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.

tyldum··on The US Tried Permanent Daylight Saving Time in the ’70s. People Hated It
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.

tyldum··on Post Mortem: Incorrect Cache Configuration Exposes Personal Information
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··on Starlink Ground Station Map
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.
tyldum··on EU agency to confirm AstraZeneca blood clot link
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.

tyldum··on Svalbard's Alcohol Quotas
Brew you can, distill you cannot.
tyldum··on Gitlab 13.10 Released
With them dropping the lowest license tier, you better start using all the features... We have been Enterprise users since 2015, but are evaluating our options.
tyldum··on How to Operate an Airport in Antarctica
Most of the cargo doesn't come from Norway. We try to ship as much as possible from vendors directly to the ship, and not via Northern Norway where the entities involved are located.

Denmark then becomes ideal as we are close with the Danes politically and it's already a shipping hub.

We could have used Cape Town, but it would be harder to have control. Very little cargo fits on these planes and the flights are extremely expensive. We operate a satellite ground station there used for critical missions.

tyldum··on How to Operate an Airport in Antarctica
Exactly. I had a bunch of servers on that ship sent from Norway by truck.

OpenStack and Kubernetes coming to Troll this season!

tyldum··on Radio Amateur Copies Signal from Mars-Orbiting Satellite
And smaller dish has larger beam width, making it really difficult to track the signal.
tyldum··on Load balancing and its different types
Another gotcha would be UDP based services. Since it is packet oriented and not connection oriented, when should it re-resolve? Most will not until the application is restarted.
tyldum··on Bare-Metal Kubernetes with K3s
Autoscaling is a field of its own, yes. Lots of footguns, though.
tyldum··on U.S. Treasury, Commerce Depts. Hacked Through SolarWinds Compromise
Things aren't black or white, but SaaS typically removes one layer of security (the corporate firewall). Misconfigurations are then typically exposed to the whole world.
tyldum··on Babelfish: SQL Server-to-Postgres Translation Layer
I have used ora2pg with great success.
tyldum··on Replacing Ansible with salt-ssh
Multiple playbooks is possible, and joining them into a large one by imports. You also have tags to do target with more precision.
tyldum··on Sweden is moving away from its no-lockdown strategy
You also need to account for how much people respect their government and policies in their respective countries.
tyldum··on Please stop using CDNs for external JavaScript libraries
Even Cisco's web-based firewall management interface uses Google Analytics. Granted, it will work just as bad regardless of reachability, so there's that.
tyldum··on AMD Zen 3/Ryzen 5000 announcement [video]
AMD lacks AVX512 instruction set, which is a show stopper for many applications.
tyldum··on How to properly manage SSH keys for server access
Authentication, authorization and access logs typically. Generic application logs can often be treated differently.
tyldum··on Backup PostgreSQL to Cloud
Useful. Pgbackrest can natively backup to S3 and Azure, for a more complete experience.
tyldum··on Tech firms face growing resentment of parent employees during Covid-19
I feel those who complain fixate on other people's benefits, but neglect their own. By not being at work, those people lose out on opportunities within the company.

And don't underestimate the stress generated by not working 100%, but there is nothing you can do about it.

Not to mention trying to pick up the slack after the kids are in bed, after you've done homework/homeschooling.

We all do our best with the current situation, it's not like we go home to slouch on the couch and laugh about the suckers at work without kids.

tyldum··on Ansible-Defined Homelab
For simple storage, rancher longhorn is also an option.
tyldum··on Ask HN: What's the worst piece of software you use everyday?
Zoom can be browser only, it just uses dark patterns to lure you to install the client. The link to join by web appears when all others fail...
tyldum··on SUSE to Acquire Rancher Labs
Rancher and Canonical were partners for a while, and Rancher was supposed to be their frontend for a Kubernetes solution.

I was talking to both of them about on-prem solutions, and found the Rancher support covered Ubuntu hosts, and Canonical support covered Rancher. Was trying to understand which support contract we would need.

But something happened between the companies and they parted ways. And neither party would comment.

In the end, we ditched Rancher support. The price almost doubled from one year to another and covered very little. I was also unimpressed by the technical chops of the Rancher solutions architect they gave us, which didn't seem to know anything beyond the basic documentation on their site.

But we are using Rancher 2 and Rancher 1.6 in production and have been happy with the solution itself.

We are migrating our on-prem from VMware to OpenStack and may stick with Rancher as k8s provisioner if charmed k8s doesn't live up to the sales pitch.

We are a team of 4 people doing on-prem datacenters on 10+ sites around the world, so we need a little bit of plug and play.

Snowcone supports Greengrass, in fact
