I have experience with an IB school in Europe - the kids have a special unit about clocks (analog and digital) in their math class in fourth grade. The student books have a lot of problems involving reading both types of clocks and calculating diffenreces between two clocks in hours/minutes/seconds.

Is it just me or the graph at the end of the article is not really showing rising adoption in general. It basically shows a couple of spikes - each corresponding to some big company switching their edge servers to HTTP/3 like Alphabet, Meta, Cloudflare. There is no gradual increase.

Furthermore, I don't see easy solutions yet for some problems with QUIC - for example browsers still try to establish a TCP connection first unless they know for sure the server supports QUIC. Proxy support for HTTP/3 is still in its infancy, but for many corporate envuronments it is a hard requirement.

So outside of the biggest websites, which I admit also take up a large chunk of the network traffic, is QUIC really replacing TCP in the general Internet?

Some EVs use paddles behind the steering wheel to control recuperation. You can switch between several levels or use max regen while you hold one of the paddles. It gives a lot of control without touching the brake pedal.

You can also use a MITM proxy tool to intercept the JS files and modify their response body to remove or replace the `debugger;` statements with something else. Might require inspecting the JS files first to see what needs to be replaced exactly, but should not take more than a few minutes.

If you install Windows, apparently Microsoft doesn't allow you to get updates (on W11) because of the Deck's lack of a "TPM".

I have installed Win 11 on my Deck because Easy Anti-Cheat does not work with Proton yet and have no issues with updates. The latest firmware (BIOS) seems to work fine for Win 11 requirements and I receive updates for Windows as well as new drivers from Windows Update.

Older Lego trains use IR for control so if you just want to control motors and lights, you can get one of those and control it with the IR blaster on the Flipper. If you also want the sensors/newer programmable hub, then you need the BLE protocol.

You should add basic rate limiting to your app. We had a similar issue with Stripe and making sure that different card numbers could not be quickly used one after the other by the same account fixed the problem.

Lots of these Easter eggs around - try searching for "joey tribbiani" and click the pizza.

Too many unknowns with the mileage solution. The most obvious for me is travelling abroad - travelling by car between EU countries is not uncommon. Another issue is that the mileage of the car is not very hard to modify. In Eastern Europe, buying a second-hand 10 year old car, imported from Germany, is almost funny because most seem to be around 90-100 000 miles (140-160 000 km), while looking for the same make and model in a German auto website will show most cars have double the mileage.

You need to have a registered address or a friend in Germany in order to take advantage of the incentives. The car must be with German plates for the first year, which presents some other problems.

Some German auto dealers are skirting the law by buying EVs, getting the money from the two incentives while keeping the car sitting for some time, then selling it abroad for a bit less than it costs to buy it there.

If you don't some of your neighbors might. I installed an app to control my AC remotely and when i pressed the button to add all units in range it automatically added one more than there were in my apartment. I had complete control over the AC unit of some unsuspecting neighbour - I could see its status and control everything from my phone anywhere in the world. I suspect it's not that bad for fridges, but you still might be able to do some harm there as well.

Went to Athens last month and saw the mechanism (a replica) in person in one of the museums. Overall, for me it was a strange experience looking at the ancient Greek civilization - these people were not thinking about simple things like sustenance or other basic needs. They were very much involved in improving their minds in any way possible - democracy, arts, science. All that time they spent on improving their civilization in every way got me thinking of all the time we lose today in meaningless stuff like social media, or looking selfishly at the world and other people.

Cameras are optional for meetings except once a week when the whole team gathers and syncs up. The day is known in advance so even people who don't like cameras have time to "tidy up". Once every two weeks we discuss team/process related issues. If the agenda is empty we still have the meeting but instead talk about community, volunteering, or just do games/current events.

I had issues exporting my LastPass database to a CSV file a couple of weeks ago from a browser (no plugin installed). They seemed to render the CSV data inside a <pre> tag in an HTML page (I have no CSV browser plugin installed). I had to copy the text manually from the HTML source and paste/import it in another password manager.

Perhaps they are waiting for someone to buy them. Even though most of their software is open source, the crucial parts are still closed IP. If it is really better than the current LKA systems and has the potential to handle even more driving scenarios in the future, it will be an easy decision for a big auto company that needs to quickly catch up.

The explanation of the failure was very strange to me. I know there are three main UPS types - offline, line interactive, and online. Offline types have the battery disconnected until there is a power outage and only use it when needed. Line interactive and online use the battery more often to absorb power spikes, brownouts, and other anomalies. These two types also use the battery more and need replacements more often than offline UPS.

I have been using the same offline UPS and battery for the last 7 years and it is still working fine - a few days ago it handled a 15 min power outage with 50% of the battery.

Can someone explain why offline UPS can fail if the battery dies? Is it by design or a manufacturer specific issue (e.g. only APC brand ones do this)?

Apple WWDC Keynote 6 years ago

Although the presentation video seemed to skip ahead on the car key part on Firefox, I noticed they said the key will be stored only locally on the phone, unless you share it with someone else. Guess we'll see next year when cars equipped with the feature actually start to show up.
