I'd argue that "correlation" is an accurate description of what you're doing with Gold codes - you're testing the known sequence of the output of a PRNG against the received signal, and only accepting it when the da

You should shout at your project managers then. The data in the ticket system should be considered important as it's the primary interface through which developers, QA and design share information.

Personal preference I guess, but to me all of those commit messages are way too wordy. I'd probably have: [PRJ-123] Refactor Foo out from Bar [PRJ-123] Include Foo data in BazClient [PRJ-456] Null-guard on Foo ID to avoid dat

I buy flights on credit card, and other one-off purchases like house and car insurance, and often my Costco purchases (because the credit card lives in a different wallet where I normally keep my membership card). My day-to-day wallet just

Most of the things I pay on the government website (except vehicle tax renewal), so basically tax, I've been pushed towards a one-off direct debit each time instead of a card payment.

Yeah, the thing that really concerns me about the other indices is the minimum free float in calculations, so not only will SpaceX appear in the index way too early, they'll be artificially giving it a massive boost, meaning that passi

The last part is easy to answer. Commit messages are solely for developers IMHO. The communication between developer and customer / product manager should be via the ticket system. That said, knowing the commit ID something is fixed in

Absolutely not. Commit messages should never be automatically passed through to the end-customer. I also worked in a place that tried it once and it was a disaster. Sure, a list of commit messages can be a useful start as a list of things t

That isn't true though. It's very easy to export your data from JIRA. From your board, go to the List tab, filter the items to whatever you want, and then click ... and you can export the data in various different formats. Exporti

You can trivially export your data from JIRA. If the parent experienced a situation where valuable information was lost because the instance was deactivated, that's not JIRA's fault.

Respectfully, I disagree. A good commit message to me is something like: [PRJ-123] Changed blah to foo Blah didn't handle the wangle flange properly in some cases, foo is a better fit for customer requirements. The "why" that

The real takeaway is that different projects have different requirements. In over 30 years of using source control, I've never once worked on something where it's useful to include the component (article calls it scope) in the des

Personally, I'm not a great fan of IPv6, but this says more about your provider than anything else. Assuming you mean for a VPS, the majority of providers provide IPv6, and a good many would advertise your IPv6 prefix and route it to y

Firstly, I think 0.15% might be significantly lowballing. Other commenters I've read trying to low ball it suggested 0.5%, which matches up with my calculations - this IPO is allegedly $1.5T on the total amount, and 25% is up for sale,

That would be true IF the stock was already being traded. All we have at the moment is just Elon saying "I think this is worth $1.5T, convincing a small subset of people to buy shares, and then because of this change, market following

Not sure if you're talking about cron or systemd, but cron definitely has that in /etc/cron.d where you can have arbitrary crontabs, or /etc/cron.{hourly|daily|weekly|monthly} where you can just place arbitrary scri

The more likely risk with a 6845 is creating a way out of spec vertical sync that can cause the monitor's frame flyback transformer to fail. Although how you describe the PET monitor's beam being "parked" suggests it&#x2

FWIW there's a good chance your fridge does more than that without you realising it if it's a fridge freezer. A lot of fridge freezers now have an anti-frost system that about once a week or so actually heats up the freezer so tha

That policy itself seems wrong though. It seems to imply that anything someone claims about themselves on a personal blog doesn't need verification. People often have a vested interest to lie about themselves, and often people may not

I was surprised to see in Taiwan last year several instances of people walking into a cafe and leaving their phone on the table to indicate the table was occupied and then going up to the counter to order.

Something I use on my own distributed system (where I wanted 64-bit IDs), is use 32 bits for the time in seconds (with an epoch from 2020, so good until 2088), 8 bits for the device ID and 24 bits for a serial number (resets to 0 every time

by ralferoo 5mo ago
I kind of addressed this in https://news.ycombinator.com/item?id=48060549 Actually, because the birthday paradox has k^2 as a term, this is actually less true than you might think. Having a time component actually reduces t

BTW I realised I didn't address why those bits are necessary - actually, while it might seem you are increasing randomness with more bits and so reducing the risk of collisions, that's not necessarily true. The old schemes generat

by ralferoo 5mo ago
Yeah, in practice the 6 bits you lose aren't important. Redoing his calculations with 122 bits and a quadrillion generated IDs (that's a million billion), the probability of a collision is 9.4 x 10^-8 (or one in 10 million) using

by ralferoo 5mo ago
It basically makes no odds, unless you consider applying a constant AND and constant OR operator complicated - as UUID v4 is just 122 random bits and 6 bits fixed. UUID v7 is a 48 bit timestamp, 74 random bits and 6 bits fixed. Sure, this i
