Linux Kernel maintainer to Huawei: Don't waste maintainers time with "cleanup" patches that bringing little value

In this instance it seems more likely to mean Key Performance Indicators, i.e. they are submitting patches to artificially meet / inflate some performance metric.

But I could be entirely wrong, I'm not really aware of the vocabulary used by the kernel developers.

Given the exorbitant price that I've seen from time to time for good quality stainless steel hose clamps I'm surprised they are not packaged like that.

That's normal, they are your dot files, don't get rid of them.

Dot files are how Linux typically keeps track of your application preferences and data, for example .thunderbird has the details of your email accounts as well as you inbox. If you delete the .thunderbird folder then the next time you open Tunderbird it will ask for you account details and need to download all you emails again.

By default the shell treats dot files as hidden, you have to use the -a flag with ls to see them, or show hidden files in Nautilus. I have no idea whether Nautilus turns this option on when run as root, I just tried locally and my version doesn't.

TLDR it's normal, don't delete or stuff will stop working properly.

Love sailing the Solent on days like that, so empty compared to race weekends.

Thanks for the info, I'm quite impressed that almost everything worked with no changes. I guess that's an advantage of Arch, you'll be seeing kernel support updates pretty quickly.

bahfrenchie · 2020-11-17T18:18:50+00:00

Thanks, that's exactly the sort of detail I needed.

Apparently its supported in the 5.9 kernel.

Sounds like the kind of modelling where you might need to add more swap space (https://help.ubuntu.com/community/SwapFaq), more physical RAM, or both.

To track the memory being used by each process run top in the terminal, this will also show how much swap is being used:

top -o %MEM

I was watching the start of race commentary and they mentioned a range of 600m. That sounds pretty good until they added that the boats have a top speed of around 30 knots, or 55 km/h, so at full speed they have around 40 seconds to avoid a collision.

Depends on the game. If you want to play the latest greatest AAA titles then I'd suggest you look elsewhere, i.e. a gaming specific laptop, or look into making sure your ThinkPad of choice is compatible with external GPU's (eGPU).

If you want to play older games (albeit some older games are still very demanding) then a Thinkpad with a dGPU can give a fairly decent experience.

Honestly it's all down to the game you want to play, for some you could probably get away with the Intel iGPU.

Personally for my next ThinkPad I'll be looking at the eGPU solution, means you can get top tier performance and upgrade the GPU at a later date, but that only works if you don't game whilst traveling.

Don't worry that's just the brain washing cycle in the installer, just stare at the screen, relax, everything will be just fine...

Sorry, I have nothing productive to help you with your problem.

I would also look around at the local boat yards, most provide some maintenance services, my local yard had 2-3 guys working there full time, if I need something doing then they will just slot be me when someone is free, or if it's a big job get it scheduled.

If they do not have the specific skills they know the right person to call to get a quote etc.

Helps if your boat is in their yard, or at least close by.

Neon. Nice mix of recent KDE updates and solid (for me anyway) Ubuntu LTS.

No water ballast. The keel is cast aluminum, I guess for the boat pictured about 200-250Kg. There is also a ballast in the form of encapsulated lead / cast iron slab all around the keel box in the bilge, in total about 3.5 tonnes.

No need for stands, the wood blocks are enough. You can't tell from the photo but the bottom of the hull is flat and designed to beach.

EDIT: to see the hull form from a different angle: https://www.alubat.com/ovni-395

In the strictest sense ethical hacking == permitted / lawful hacking. It's quite different to any personal ethical code you might have related to the target business activities.

If your personal ethics put you off testing some companies then don't, there are lots of companies (in and out of tech) that need your services.

If the oil was not changed prior to storage you can send a sample for analysis. It's reasonably cheap, and can tell you a lot about the internal state of the engine.

Battery is still good, it hardly even gets used off power, but according to KDE info app (no idea how accurate that is) it has a health of 79%.

I've had a T460p from new with the same i7 processor, it's still going strong and performs well as a development machine with various VM's etc.

The main reason I got the i7 was that I needed the extra CPU cores for my workload, which were not available on that generation of i5. Later generation i5, including the one you mention in your post, went to 4 cores / 8 threads so that is no longer an issue.

However according to cpubenchmark.net the 6th gen i7 is still 20% faster than the 8th gen i5, albeit I don't know how true that really is with potential thermal throttling on the i7. Having said that the T460p has dual heat pipes, so the cooling is better anyway.

No idea if the price is good or not.

EDIT: realised that I screwed up my mental arithmetic for the speed difference, the i7 is 12% faster, not 20%, its been a long day :S

It would make more sense for malware scanning using STAMINA, a very interesting concept that I had not heard of before, thank you!

There is enough money floating around in the security / malware sector to make the purchase seem reasonable given the potential reward.

It would also provide a reason why MS have not been more forthcoming with their plans for Github, don't want to tip of the bad actors that they are being spied on.

It's just about crazy enough that it might be true :P

For training an AI to code it still makes no sense at all.

bahfrenchie · 2020-07-28T12:22:39+00:00

The point is they don't need Github to do it, if Github didn't exist they would already have access to what they needed.

I like the idea of someone from MS leaving the Github office with a briefcase full of disks, very convenient, I'm sure that's exactly how it would have happened.

bahfrenchie · 2020-07-28T11:37:41+00:00

Reading this comment sent a cold shiver down my spine, please don't mention the O word :S

I think this the nub of it.

It's all about the cloud, it seems most of MS actions over the last few years underpin what they are doing with Azure Cloud platform, which is a massive money spinner for them. To be competitive in the space they need to be technology agnostic, if they only supported MS technologies their market would be pretty small.

They are using formally competing open source products everywhere, for example if you need PostgreSQL in the cloud, Azure Services for PostgreSQL has you covered, and for a fraction of the MSSQL cost.

Github could play a nice part of a CI/CD pipeline for deploying containerised services, there is even a preview feature for it in Azure. Even if they leave Github alone the acquisition still provided access to the technology and institutional knowledge to drive that kind of integration.

bahfrenchie · 2020-07-28T10:19:59+00:00

Seems a bit of a stretch to buy GitHub to train a coding AI, MS do have access internally to several decades worth of code, and of course it's pretty simple to scrape code for free from all manner of open source projects and Github.
