Almost like that xkcd joke…

Who needs 20! Lol. Says more about me than you.

Is the copied file going to a usb? Is the usb fake? Otherwise I’m pretty sure your source is bad. Probably the disk sector if you’re sure the file was at some point complete.

Something like btrfs probably does block cloning or similar so a copy to the same disk probably just points at the same disk blocks as the original.

ffmpeg -v error -i file.avi -f null - 2>error.log

Check the source probably

How are they placing this data? Api? Not possible to align disk tiers to api requests per minute? Api response limited to every 1ms for some clients, 0.1ms rate for others?

You’re pretty forthcoming about the problems so I do genuinely hope you get some talking points since this issue affects, app&db design, sales, and maintenance teams minimally. Considering all aspects will give you more chance for the business to realise there’s a problem that affects customer experience.

I think from handling tickets, maybe processes to auto respond to rate limited/throttled customers with 'your instance been rate limited as it has reached the {tier limit} as per your performance tier. This limit is until {rate limit block time expiry}. Support tickets related to performance or limits will be limited to P3 until this rate limit expires."

Work with your sales and contracts team to update the sla to exclude rate limited customers from priority sla.

I guess I’m still on the “maybe there’s more you can do to get your feet out of the fire for customer self inflicted injury” like correctly classifying customer stuff right. It’s bad when one customer can misclassify stuff and harm another customer with an issue by jumping a queue and delaying response to real issues, when it’s working as intended.

If a customer was warned and did it anyway, it can’t be a top priority issue, which is your argument I guess. Customers who need more, but pay for less and then have a expectation for more than they get. It’s really not your fault or problem. But if it’s affecting you I guess I’m wondering how to get it to affect you less.

If it’s possible to do, and it causes a user experience issue, especially one as jarring as “stop accepting writes” you should start adding rate limits and validate inputs with rate limits expressed to the user before they hit the error rate.

To me you should already be sanitising input anyway, and this would just be part of that logic. If a user is trying to upload more than x it warns (with link to documentation of the limit). If user has gone past the rate limits, then error.

I’m not a sre or dev, just a sysadmin though. Users expect guard rails. If it’s possible, it’s permitted.

Many of those types while having great brightness and reduced image burn in actually have terrible quality images. Eg no hdr, some may only be 30hz, some may have the contrast ratio which is so low you’ll just be sad to watch a movie on it looking at a black grey mush.

Though like all things, there’s a gradient. Some of the conference room monitor panels can be better but often >3x more expensive than the consumer model due to much better warranty (eg same day parts).

So I don’t have any advice here, just a bit of warning with experience with being around zoom, teams, and display walls from an IT solutions perspective,though generally I use AV partners for model selection and installation on any meaningfully sized conference/boardroom room or special application eg stages.

Mm, not quite, when say having 60+staff work in a single building model you need something that allows object locking so stag can work on part of a building and check it in and out.

I’m not the architect, I’m the sysadmin that designs and builds the server/network infrastructure for a half dozen architecture firms, some which have over 300 architects spread around Australia, Europe, and south East Asia. That mostly means running up servers to host BIM and BIM cache servers, as well as maintaining PIM servers.

To be honest I quizzed you because I honestly never heard of it and my life revolves around both revit and bim360, revit and revit self hosted bim servers, or archicad. Not that I do anything much in them, BIM managers generally administrate their own BIM instances and their teams. But some of the projects are in the billions of dollars that you’ll find on featured on the b1m YouTube channel.

Id argue that while the architects themselves are by and far the largest cost, the largest IT cost is the modelling software. I’ve even had some people using unreal engine to do parts of their work now especially for customer facing flythrough demonstrations and city view with time of day and all that.

So I’m pretty open minded to keeping my ears open to new software since I’m never sure what to expect. It would be interesting to see if it could ever be possible to do one of these megaprojects in open source. But my gut says it’s unlikely.

Does it connect to the same arcgis BIM servers so I can work with my coworkers, in real architecture projects?

I use Ubuntu, it’s the default for ROS. I tried debian but the instructions didn’t work instantly so I just as quickly gave up and went back to Ubuntu since I was busy. Lol.

Yes, but first go check which list you want to use since they’re a good starting point to understand a kind of level of tolerance and expectations around your experience.

There’s lots of lists around here’s a small sample:
https://arstech.net/pi-hole-blocking-lists-2023/

Be prepared for a bump in time outs as you work through things you might need (I blocked by accident a bunch of needed Microsoft services that I need to use during my job).

I haven’t edited my white list in months, maybe over a year. It’s going very well. I’ve been running pihole on ubuntu for more than 5 years as two virtual machines. I’m happy.

I’m not in America but the organisation for NIST recommends it in guidance now and its getting backing by the nsa

I see this becoming required in the future for new projects and solutions when working for new governnent solutions. The drum is certainly beating louder in the media about it.

I love the hand gesture at the end!

Start realising that the way you’re used to scrolling with your mouse wheel, is a cog between you and the service it’s moving. Actually you were using natural all along. It was the early touch pads that were wrong and nonsense.

Traceroute.

Look it depends on the age of the car, but let’s take an old manual car for example.

On those cars, there’s a fuel map to rpm. There’s actually a few maps including throttle and ignition timing. But think of a spreadsheet of rpm and fuel at a certain throttle load.

At 0 throttle: The map says to stop the engine from stealing at under say 800 rpm it needs to have fuel added at rpms lower than that to speed up the engine to avoid stalling. At 800rpm it needs a consistent amount kind of a known amount that keeps it in equilibrium. At over 800rpm it needs less fuel the more rpm it has over the idle 800rpm until it’s zero fuel.

And you’ll feel that, you’ll feel that moment the car starts adding fuel because if you’re only engine braking to a stop your car will get near that idle rpm and your engine will start adding power to avoid a stall, and your braking will diminish.

If you take an engine out of a car and try to spin it by turning the crank shaft, it will be hard to turn because the cylinders need to compress air (it’s required before adding fuel and spark to explode that compressed air so it expands).

When that engine is in the car, and you don’t add fuel and spark, then the cars wheels have to turn the engine and compress that air, thousands of times per minute. That force that the wheels have to send to the engine to spin that engine slows you down.

I’m thinking you think the engine itself has a brake on it… No.

Hi, I run pop! Os for about a year on a mac book pro 2012. My biggest hassles are Bluetooth audio sucks (glitchy) and I had to install a wireless driver to get wireless to work at all. Other than that, it’s working exactly as expected. Can recommend. It can’t game, it can’t play videos well because the inbuilt speakers suck (and the Bluetooth audio is glitchy), but it’s plenty performant for my actual tasks. Runs smooth. I’m sure most distributions will.

I think that’s a good idea, good luck with it!

I can guess at some things but let me first start with what I think is happening:

You have a gateway set. Your device sends a broadcast arp message asking 'who has ip ’ and the device with that ip is supposed to send back ‘me with this mac address!’.

That device is either sending it so slowly that your machine says ‘I can’t go past the gateway, the gateway isn’t responding’ which in your error message is no route to host.

Assuming that you have no custom manual network route in play.

So things that can cause that are usually link layer and layer two issues and sometimes duplicate IPs. Two devices with the gateway ip.

You should watch your mac address table and arp table (arp a) and watch if the router gateway disappears or changes Mac addresses.

Don’t feel bad because you’re really good at using a tool that doesn’t follow your values. I use Windows during the work week and I use Linux for gaming on the weekend where I literally can’t work even if I wanted to.

For me Windows is a tool box with propriatry tools that have no Linux compatibility. That’s OK for me. People get emotionally invested but that’s neither healthy nor helpful. No point being angry at work, it’s like being angry that your work uniform is made by one textiles vendor not the other.

You get to choose what you use at home in your own time. If you feel good using Linux then, do it!
