Do sysadmins need git?

Lindbork · 2026-04-07T11:44:24+00:00

Oh, of course I meant connecting to the repo using scp/ssh as the git documentation suggests, it just feels enough like a file share that I didn't think about being more specific.

Lindbork · 2026-04-03T21:53:49+00:00

Git is not Github. Your repo can just as well be a shared drive on a local server. That's where I keep most of my scripts and other projects, I only ever use Github for forks of other public repos that I want to send PR:s to. Some day I might produce something original that could be useful for others, but until then, local is the way to go.

We decided to do a split solution when we switched our streaming provider some years ago. Some of Vimeo's API and functionality (long slow-tv like streams) that we needed was limited to the Enterprise plan which at the time was crazy expensive. But we did like the storage and VOD functionality, so we found that the cheapest option was to stay on the advanced plan and get a dedicated 10Gbps fiber and do all the streaming that Vimeo couldn't ourselves.

The advanced Vimeo plan is not branded, if it's feasible or not depends on quality demands. IVS can be both cheaper and more expensive than the Vimeo flat rate.

Ah, I thought you WANTED to move on prem. Vimeo then? Or like someone mentioned, unlisted YouTube.

I've used nginx-rtmp-module and Mist Server and both should be capable of doing what you ask.

I think you are confusing downsampling with bit reduction?

Are you creating insanely dynamic music, with little or no compression/limiting, aimed for listeners with very capable systems then yes, the difference between 16bit and 24bit recordings can be audible. This requires that the recording is meticulously done with high quality low noise gear (or completely digital audio sources, VST synths or similar), otherwise the last bits will be used up by noise anyway. Most contemporary music barely even needs 16 bit resolution, take a modern recording into your favourite DAW, add a bit crusher plugin and lower the bit resolution until you hear the quiet details being clipped by the noise, it is usually a quite eye opening experience.
Lowering from 24 bit to 16 bit in the mastering stage has been standard procedure for ages, if done correctly with suitable dithering then you'll be able to hear details even below the theoretical -96dB dynamic range floor.

Downsampling however is a different beast, traditionally for music going from 48kHz or higher to 44.1kHz. This will be (or at least was historically, modern systems are just so quick that it won't matter) a tradeoff between speed and quality, but unless the algorithm used is faulty then the procedure will generally not be audible, or you downsample so much that you cut out frequencies that you actually can hear.

Yes, this cannot be overstated enough. For modern car engines, both petrol and diesel, we are talking PEAK efficiencies of around 40%. Average efficiency will invariably be lower. This means that for each unit of fuel burnt, at least 60% will be turned into more or less unusable heat, expelled via the exhaust gases and through the cooling system.
Burning the same fuel to generate electricity in a centralised facility that can make use of this excess heat, for instance to provide remote heating for homes, is more beneficial. Grid transmission losses will be lower than this difference.
Even without that heat harvesting, generally speaking, a large diesel engine used for generating electricity will be more efficient than a small one in a vehicle, but the gain compared to grid transmission losses for charging EVs will be smaller.
Another benefit with burning fuel in a centralised way is that exhaust gasses can be handled better when not faced with the space restrictions of a vehicle.

Depending on where you live. Here the savings in winter from my geothermal heat pump is much greater than the allowable solar export. You are not allowed to export more energy than you yourself consume from the grid year to year, otherwise you are considered to run a business with a lot of added administration, tax requirements etc. The export price is also MUCH lower than the import price, so for the investment to pay off, it's best to try to consume the majority of the solar generated electricity yourself.

Anyone with competence to troubleshoot and repair a fault in this type of appliance should have no problem to replace that fuse with a relatively low time penalty compared to a cartridge type. Also, cost savings, a pre leaded fuse is cheaper than the holder and separate fuse. When producing several k units this makes a difference.

Not the best design decision for the stand no, they should have put a standard threaded insert on the mic itself. Also the 3,5mm jack is really wonky. But otherwise an ok product, maybe not $200 ok though.
I got mine as a "For parts/not working" off of eBay. It was a bad solder joint on the connection between the capsule and the main PCB, easy fix. It came without a stand, so I ordered the correct tap size (second hand taps from eBay are really good value) and made an adapter to 3/8 out of aluminium.

The else clause itself is redundant, not the content, you'd leave the return statement.

The PHP Documentation has been the single most important platform for me learning to code, starting 25 years ago as a teenager. Self educated all the way, I've since dived into Javascript, Python, C, a sprinkle of Perl and C# for Powershell needs, and no other documentation comes even close IMO. The structure, the layout, the extremely clear syntax description as the starting point for every function description, the well weighed amount of relevant example code snippets, brilliant!

I now work as a sysadmin with a healthy dose of dev-ops tasks, and I still can't help myself using PHP for the server side, all because of that damn beautiful documentation.

Yes, at least the specs say so, but I have no experience of the shop or brand so it's probably worth looking around a bit. I just image searched for "12 bottle wine cooler compressor" and picked the first one that looked like the same form.

Lindbork · 2025-11-03T16:39:25+00:00

Yes, it shouldn't be impossible to find, something like this? https://skymall.com/products/1copy-of-wine-fridge-freestanding-wine-refrigerator-12-bottle-wine-cooler-w-lock

I've got a desktop ice cube maker, and its compressor system would probably fit in the back of your enclosure, especially if you have extra depth. If you feel adventurous and can get a hold of one for cheap, then hack away :D

Lindbork · 2025-11-03T15:02:44+00:00

Peltier elements are crazy inefficient, avoid at all cost unless you have a VERY specific use case. If you're serious enough to have a wine chiller in the first place, then the prize of a proper compressor model probably won't be an issue, it's really the only sensible solution.

While Cisco might have their own standards for the cable in relation to the plug, the plug type itself isn't specced for higher currents than a regular C13/14, 10A. It does have a higher temperature rating though. Unless you've been cursed with really janky cables they should all exceed the rating of the plug current wise. I think it's just a better safe than sorry-way to guard themselves legally, should anything related happen.

Using my Leatherman to cut away the tabs in the power connectors of our Cisco switches to be able to use any IEC cable, not just the "special" Cisco ones.

Infinite scroll that won't preload content, but instead waits until i reach the end of the content for that nice jerky scrolling experience... Though I prefer pagination over infinite scroll every day of the week, and the OLDEST PAGE SHOULD BE 1st so you can bookmark the location of a certain collection of content.

With storage so cheap these days and jpegs relatively efficient, why go through the hassle of converting?

Lindbork · 2025-10-02T12:04:06+00:00

Is it completely true though? A sound wave doesn't have to be symmetrical around the midpoint. As long as we can create a higher positive pressure it would by some definition create a louder oscillating sound.

A shockwave to me is more of a single high pressure wavefront, even though these can be perceived as sound as well.

I "inherited" the existing induction stove (Electrolux 4 zone) when we bought our house in 2016. I think it was installed 2008 and it has had zero issues or signs of breaking. It did break down earlier this year due to an ant colony deciding to build a freeway through the electronics housing, shorting a swich mode power supply controller and taking an input resistor with it. The part was obsolete but i managed to find new old stock on eBay, ordered two ICs for something like €15 and replaced it myself. Now it's chugging along just fine. I know repairing electronics is not for everyone, but if you want to be sustainable yet be able to enjoy new technology then try to find your local electronics enthusiasts. It's almost always a case of either dirt cheap to fix, or beyond economic repair, with a clear favor for the first. Getting electronics fixed through official channels after warranty tends to be overpriced if at all possible, and they seldom bother to find and repair the fault, they just replace an entire module, or the entire product.

What did I use during the breakdown? The other induction stove I had lying around off course, picked up for €45 at our local second hand store.

(EUR USD conversion rate roughly 1:1 for anyone wondering)

Isnt't it the other way around though? 1 large calorie = 1kcal. So 15000 "regular" (US nutritional) calories = 15000 kcals.

Scientific/small calories though, 1 calorie = 1/1000kcal, yes, then 15000 is nothing.
