MacOS has some very strange ideas on removing permissions. When you allow kexts in modern OS releases, the signature gets added to an SQLite database in /var/db (you have to consul…

Not any more: https://www.theverge.com/2018/11/12/18077166/apple-macbook-a... "The parts affected, according to the document, are the display assembly, logic board, top case, and T…

64GB will cost you $800 now . When you need it, it may cost half that, or less. And Apple was notorious for underspec'ing the maximum amount of RAM a machine could take - it was co…

Even the XPS 13s are more serviceable than their rival MBP 13"s. The RAM may be soldered on both but the XPS uses a standard NVMe SSD. It's saved me a few times already.

Not just the risk of data loss, but the inconvenience of restoring the machine is much higher. This means the only solution to restoring a modern Mac notebook is to replace the ent…

Xbox One X. Now with 40% more confusion.

Mostly bandwidth, reliability and interference robustness. The Wii U certainly proves it's possible, although that's streaming 1280x720. Displays at much higher resolutions require…

I wasn't aware of this kernel flag (nor am I surprised it exists), seems like it would be useful to the article's author. However, by default it's left enabled, which allows the ke…

Linux provides /dev/random and /dev/urandom to all applications as well as relevant API calls, but the quality of those is always in doubt (especially with urandom, which recycles …

My understanding is that implementing a PRNG in software results in a very small entropy pool. At the OS level, it can collect entropy from a vast number of sources, including thin…

By which time the next release comes out. You can't win with Apple now.

Disk images don't work with Macs any more. Apple has forced us onto 'workflow-based' installations which are supposed to ensure firmware for all subsystems are installed as well, b…

Well now, that's interesting. I include LibreOffice v5 with my standard install of Mojave. I ran a fresh install earlier this week just to test the upgrade, which worked. Only then…

No question that this idea would be pure hell on a cramped plane in cattle-class. There's even mention in the article that, yes, the plane can manage the flight, but even with a fu…

Agreed, I do and don't want to know what on earth Google was doing with /var that led to this situation in the first place...

Indeed, just the first page was enough for me. The OP made a simple point - that clearly-stated facts didn't add up, and the entire first page was either suggested workarounds or u…

I think you have the wrong idea, I read nothing in the article about Greta criticising her own parents. Your quote itself even states the target - world leaders. Her argument is co…

As much as I admire Scott Adams as an insightful and intelligent cartoonist, I don't agree with his post here. The children who started the Extinction Rebellion were not, for the m…

I'm guessing they have had to deal with DDoS attacks a lot, and as a sysadmin I can sympathise with their frustrations - it doesn't just affect the person fleeing to them, it affec…

Okay, fair point. I can only assume they would only do this for persistent and malicious violation of the rules; it's a pretty good incentive not to do anything nasty with them if …

It does indeed go beyond a suspension, it's a ban , and that's why I equate it to Amazon and Google blocking any new accounts - they are banning you from their platform, arguably f…

Many platforms (e.g. Amazon, Google) will block your account without warning and any new ones you create trying to get back into their platform, and defend their behaviour with gen…

Personally I'll take a blunt 'no, we won't tolerate this' over a load of hot air. Get to the point and let's move on. This gets my approval.

The out-of-network stuff is the most insane part of the American health system. No question, it's deliberately set up to trip up those who need urgent care. There are plenty of sto…

Very. Which is why the NSC was built to isolate it for at least 100 years (presumably it will be reinforced regularly by successive generations). Nothing we can do except allow it …
