xen0··on Takeaways from the Jane Street bond prospectus
More like 180,000 full time employees, and probably at least that number again in external and temporary contractors etc.
xen0··on Razer made to pay $1.2M over 'N95' face mask that wasn't
> Their laptops had a 50% failure rate at Linus Media Group, according to Luke during a WAN Show. Linus kept pushing them on his viewers though.

Do you have link to that particular show? It's surprising it was mentioned and that Linus was still 'supporting' it at the time.

xen0··on Google layoffs hit Flutter team
That the current team has just been mown by the latest swing of the scythe, doesn't mean the product is being killed.

At least in some other cases, other teams are being spun up or being changed to take on these projects.

Of course, that doesn't mean this isn't disruptive or unfortunate.

xen0··on Google Earning Q1 2024 [pdf]
People layed off (about 10,000) in Jan 2023 were still on the books in March 2023. Termination didn't take effect until April.
xen0··on Google Earning Q1 2024 [pdf]
That doesn't scale.

AFAICT, Google didn't go to the effort of creating vague objectives for people to fail at. Instead they've blanket cut teams regardless of their success or performance.

xen0··on The xz attack shell script
Mostly correct; there's some code that's Blaze only and some that's Bazel only, but the core is the same.
xen0··on What Boeing did to all the guys who remember how to build a plane
Anecdotally, the average member of the team I'm in (in Europe) is probably mid-30s with at least 10 years of experience.

Less than 5 years of experience at Google is, to be fair, common. But the company doubled in size over that time, so it's inevitable. And higher turn over in tech is common (and I don't think that is necessarily reflective of anything other than the fact it's easy to get another job as a software engineer).

I can't state much on the layoffs because my team was not heavily affected.

xen0··on Cream is thicker than blood: the rise and fall of the Devon split
I think one might struggle to pipe clotted cream, or produce anything so 'elegant' with it.

It's thick, being mostly fat (often >60%). At least in Cornwall, it's often bought in plastic tubs like ice cream (it will hold its shape, not flow), not jars or bottles.

xen0··on Cream is thicker than blood: the rise and fall of the Devon split
As someone from Cornwall, the pictures in the article don't look right. Clotted cream is much thicker; those cakes look like they're made with whipped cream.
xen0··on Tank Museum in U.K. Playing Big Role in Keeping Ukraine's Armor on Track
How many T72s have to be kept outside for 50 years to have one functioning T72 at the end?
xen0··on "AI, no ads please": 4 words to wipe out $1T
Not outright illegal, but in some places it's often required that what you're seeing is clearly an advert, or contains advertising.

For example, a watermark or logo is shown at the start of a broadcast containing product placement in the UK. Prior to 2011, it was 'forbidden' for broadcasters entirely. (Quotes because you could still broadcast films that may arguably have it)

xen0··on "AI, no ads please": 4 words to wipe out $1T
That might be illegal in some jurisdictions.
xen0··on Hyrum's Law
Hope you like firing people.
xen0··on German credit agency earns millions through unlawful customer manipulation
In the UK at least, credit reports largely happen behind the scenes, and potential landlords etc cannot perform a full credit search. With your permission they can perform a 'soft' search (have you declared bankruptcy or do you have any County Court Judgements) and they may not charge you for doing this.

Further, as of GDPR, you are entitled to all information from the agencies for free. Prior, you could obtain it for a small fee (£2 by post if my memory serves me correctly).

As far as I'm concerned, SCHUFA is basically a scam I am compelled to fall for whenever I want to rent somewhere.

xen0··on Gemini can't show me the fastest way to copy memory in C# because it's unethical
Definitely had those. Just wasn't sure about the Buffer.MemoryCopy function.
xen0··on Gemini can't show me the fastest way to copy memory in C# because it's unethical
Couldn't reproduce. But maybe it gave me the wrong answer; I am not a C# expert.

But I have had some success in bypassing its moral posturing by asking it in German. It will happily translate for you afterwards.

xen0··on Discord is laying off 17 percent of employees
Google are being shy with the numbers. Confirmed 'hundreds'; probably very low thousands? Maybe 1%?
xen0··on Japan's airport control towers stop using 'No.1' instruction for plane takeoffs
As a non-native speaker, I've used it a couple of times at a bakery to make sure I don't get too much of what I'm asking for.

Doesn't help when I _do_ want three of something though...

xen0··on Astronomers detect highest energy cosmic ray since 1991
Approximately, yes.

We talk about 'high energy' because there's an upper limit to speed (the speed of light), but there's no limit to how much energy something can have. The increase in energy increases mass and speed (and therefore momentum), with it mostly varying mass as you approach the speed of light.

A proton moving at 99.5% the speed of light is not moving much faster than one moving at 99%, but the former has much more energy.

xen0··on Citadel CEO Ken Griffin: Remote work makes it easier to fire people
> Heck, you wouldn't say that Ken Griffin is full of shit to his face if you met him but you said it on an online forum.

They might say it in in-person conversations with their colleagues.

Yes there's a level of detachment that comes from being online, but the bigger distinction is more 'who' you are talking to.

xen0··on My favorite coding question to give candidates
> If you want to import a day's worth of access logs into a hash map, you need to take into account not only the time but also the space complexity of this sort of solution.

Good thing space complexity is routinely discussed in these interviews.

And the idea that computation complexity only matters for 'the hot path' is way too dismissive.

For instance; a quadratic loop over a 10 million line log file is just a catastrophe (100 trillion iterations), even for something run once a day. Such a log file would happily fit into memory (it's mere gigabytes) and a hashmap would be perfectly adequete.

> Depending on how much traffic a service handles

Yes, it depends. The interviewee is expected to ask, or at least state what assumptions they're making.

xen0··on My favorite coding question to give candidates
Describing 'throwing a hashmap' at the problem as 'premature optimisation' is a bit reductionist.

It wouldn't even occur to me to go with the naive O(n^2) solution because it has such obvious drawbacks with large inputs.

And it's an interview question... yes, you're getting a No-Hire if you just leave it there. Although I personally would prompt you if you're not interviewing for a senior position.

xen0··on Meta Now Charges $200 Annually for Privacy – A High Cost for User Data Security
The point is is that the value the company derives from targeted advertising against a given user is clearly an order of magnitude less than the headline $200 they ask for not being able to do it.
xen0··on Meta Now Charges $200 Annually for Privacy – A High Cost for User Data Security
Some quick googling:

Estimated users of Facebook: 3 billion. Meta annual revenue: $120 billion

3 billion × $200 is significantly more than Meta's annual revenue.

There's paying for a service and there's being ripped off.

xen0··on WeWork Goes Bankrupt
I don't think his reputation is so tarnished that he can't get other investors to continue to give him money.
xen0··on Subtle ways Microsoft Word has changed how we use language
"12:00:00 + ε" is after noon, but your clock will not show a difference.
xen0··on Safety benefits of roundabouts
The normal terminology for the sides of a car are 'nearside' and 'offside', with the nearside being where the kerb is, offside being where other cars would be.

So I would suppose 'inside' and 'outside' were also considered relative to the kerb.

xen0··on Things I've learned about building CLI tools in Python
The equivalent to static linking in Python would be bundling all code into an archive (including transitive dependencies), along with an interpreter. Some shell script can be used to unpack and run.

It's possible, just not the norm.

xen0··on Meta is banning people from advertising after running ads for Python and Pandas
You never made a mistake?
xen0··on Ammonium chloride tastes like nothing else. It may be the sixth basic taste
Meats and animal fats taste distinct from lettuce leaves, and the obsessions we have over the former suggest we find them more desirable.

(Sweet things indicate easily broken down sugars, a sub-category of energy rich)
