Besides from Bluetooth and USB:

- 433MHz is very much alive (various RF-controller lights, gate openers and such) AND can be used to remotely control another Flipper.

- Both 3.56 MHz and 125kHz are alive in door locks and RFID tags.

- IR is still alive with most TVs.

So yeah, it's missing 2.4 GHz ISM stuff. But given hardware they packed in, it's a rather good multi-tool.
I re-created a stock ticker machine. I saw an article about them on here and thought "oh that would be cool to have one, lets try and buy one" I realised that they cost $4k+.

You are accusing me of denying the problem exists, when in fact I am not discussing any specific problem at all. You are letting your feelings take over and paint me as your adversary in all things, when in fact I am not.

The rise of reporting of something does not prove any increase of the actual incidents of that same thing. They are not necessarily correlated.

> I'm not claiming these stories to be factual or correct, but the news being reported […] suggest the growth is likely a result of the pandemic, among other factors.

You just assumed that the increase in reports correspond to an actual real phenomenon. They might, but do not have to be.

> The whole point of having a free press is to have an informed public that influences government policy.

The press cannot solve these problems just by publishing stories, and it is ludicrous to think that the authorities are not aware of the problems and trying to solve them. So what value does the press bring by pronouncing some problem to be the latest catastrophe? As far as I can see, all it does is give politicians a specific problem to claim to be able to solve if they were elected. But they won’t solve it, because if the problem could be solved, it probably already would be. And the damage done in the name of solving the problem may be much worse than the problem itself, if it ever was significant in the first place.

Your proposed solution would make it easier for people to report one another for serious crimes, which would have the potential to ruin very many people’s lives. Likely magnitudes more people than would actually be helped. Systems where people can very easily report each other to the police (or other unaccountable overseers) tend to turn out like that.
"RHLF" is Reinforcement Learning from Human Feedback? (Strange acronym.)

I don't see how that helps a a tool become useful to a very skilled person, if the "human" side of things is polluted by 95+% of users having very low skill. It's great that you can train LLMs on the world's best reference material! But I don't see how you can get the world's best updates into that training set without hiring the world's best experts. So the tool will have very little value for anyone above a certain skill ceiling. Search has already fallen victim to this effect (I'm tired of results pages full of beginner material when I have a deeper question!) and I cannot see this being better for augmentation training sets for LLMs.
I yearn for the day when I can use my swan pedal boat to go to China to pick up my aliexpress shipment.
Why can't we support and encourage cycling without vilifying cars in these threads? I've seen plenty of places that do both very well, like Spain. Everybody has a car and bicycle (at least one) and uses whatever fits the purpose at the time.

I get it, when there's not cycling infrastructure everybody is forced to take the car even if it doesn't make any sense, like for short trips, good weather, single passenger, no significant cargo, etc. But there's plenty of occasions when you really need a car.

Also, taking Spain as an example again, scooters and motorcycles are often a better compromise. Practical speed for longer distances like commuting to work, better weather protection, larger cargo capacity, can take 2 people, etc. Why are they always ignored in these threads? Is this an American thing?
The irony is meta has none of these things. It’s the least bureaucratic place I’ve ever worked. Whether or not that’s a good thing I’ll leave up to the reader.

I remember wondering why predestrian/cycle bridges were always so annoyingly narrow despite having low loads.
The issue is of course that they have to be strong enough to support being crammed with hundreds of people when everyone is there to watch the local fireworks/rowing race/anything else that's happening, even if that happens almost never.
Somehow, yes. Except for

In theory, the tool is extensible. The first version used an e-Ink display, which of course requires a different way of communicating. So the docker service can upload either to a FTP, or can communicate via REST at the moment. I really only implemented what I needed at that time.

"On a boutique hotel website, maybe I'll get a phone number that I have to look up the international dialing code for and then call in that country's business hours, if their website isn't just completely broken."

If call them on the phone that implies one can speak the language. If hotel has a website that suggests it has an email address. Not sure I would want to stay at a hotel with a broken website and no email address.

I've never had problems booking through an intermediary but the parent is correct to the extent there are some benefits to dealing directly with the hotel.

It's really sad that so-called "tech" companies and internet marketing companies have bought out the independent travel guides, took the data and made it unreasonably difficult to find the contact info for hotels online.

But we can always find the contact info in Google Maps. Frommers and Zagat both acquired and pilfered by Google. Very sad.

Here is a website that will provide the website address and the email address for each hotel.

So just because the "th" sound doesn't exist in many languages, like German, they should pronounce "Heath Ledger" or "Anthony Hopkins" or "The Beatles" incorrectly? That seems to me a way more "insane" standard. By the way, the Scottish are perfectly able to pronounce "Loch Ness", which has the same sound for "ch" as "Bach".

My AirPods Pro often fail to connect properly, appearing connected but music still plays on cellphone.

As an introvert, I don't like to bother people. When I'm in a quiet coffee shop or library, I turn down my phone volume, select a white noise track in Apple Music, and put my ear near the bottom of the phone.

So, I created the simplest app of my life: open the app, and it plays the sound of waves. If your phone is in silent mode, it won't play anything when the connection fails, even if the volume is high.

I posted it on the web, and many people didn't understand its purpose, thinking it was just another white noise app. It received very few downloads. However, it's the only app I made that I use every day.

In the end optimization is always important, but different kinds in different stages of the project. Changing the structure is the easiest at the start when there's not much code, while doing crazy performance tweaks of a function that may be thrown away a day later is a waste of time.

Was a long time ago, but I used to play this game called DayZ, which back then was just a mod for ArmA2. I played on a private server hosted by a friend.

Back then the game was very easy to cheat in because even though the map was huge, the client kept all of the objects in memory along with their positions all the time - and it was very important in the game to stay hidden from other players and to hide your stashes of objects for later use. All of these was available in memory for grabs and there was no anticheat.

So there were people who wrote cheats that just grabbed the positions of those hidden stashes and bee-lined through all of them, robbing them.

The server logged the position of static objects (like stashes) on startup and logged the position of every player every few minutes. So I wrote a very simple application that parses that log and puts all of that information (position of stashes and players) on a human-readable map. The admin could then select a player and track his journey. It was very easy to spot people running in straight lines from stash to stash, it was obvious they were cheating and should be banned.

After that I added some heuristics that detected these behaviours automatically and gave hints to admin on who to check. There were more abuses possible in the game later on that I also detected.

For example, there was a "dupe bug" which allowed a player to duplicate a backpack full of useful items and give it to their friend. It involved two players staying in the same spot, dropping the backpack on the ground, trying to open it up by two people at the same time, one of them disconnecting, etc. The backpack was duped due to lag on the database on server side.

I modded the server files to log the information that a backpack was dropped or picked up (along with a list of items inside it in order they were arranged). Then I modified my log parser to look for two players being near each other, dropping and picking up the backpack, disconnecting and reconnecting constantly and detecting two backpacks with exactly the same list of items in the same order they were arranged it (which was very unprobable to happen out of itself) - detecting this gave a hint to the admin to check these people out as possible dupers.
> In addition to suggesting de-tracked math offerings, the draft framework also proposes to incorporate social-justice lessons into math, and to orient lessons toward seeing how math could advance social justice.

And this is controversial? I thought we all agreed state education should be used to create the New Soviet Man. "We'll get you through your children" is a proven effective method, the only problem is resistance by backwards parents.

On the subject of tracking math, when I was subjected to it, I just didn't get it.

The entire idea seemed to be giving students who were bored by the material more work than other students so they could be even more bored by the material but while never going at a faster pace because that would result in students learning material that wouldn't show up on that years standardised tests. Tracking was the norm, but at least my school was extremely reluctant to either let people skip a grade or hold back people a grade so they were preparing for standardised tests that provided them a reasonable challenge, as that would mean you were doing school with people who weren't your same age peers and that's bad!

I just never really understood why these tracked math programs were a good idea? They seemed EXTREMELY stupid to me at the time and I just don't understand how these classes were ever supposed to be a good idea. In the non-tracked classes you could at least blow through the work you were assigned more quickly.
I created a cycling statistics dashboard on a Raspberry Pi with a Pimoroni Inky Impressions e-ink display.

Microsoft has been interested in using memory safe languages in the kernel for some time now. An example is the Midori project led by Joe Duffy back in 2009 which explored the idea with a C# derivative.

Rust is a game changer in that it is built from the ground up to offer memory safety without garbage collection and still aims for zero overhead abstractions.

It would be ironic, after their notorious security issues of the early 2000’s, if due to efforts like this, Microsoft Windows ends up being the most secure general operating system.

It's sad to have to look so far back but:

I installed linux for the first time in 1992 on my parents DOS machine. I had another partition for it. It was Slackware with kernel 1.2.13 I think. All off 5.25 inch floppy disks.

Setup wasn't so simple then and I was a UNIX Noob so I managed to set the swap partition to the DOS hard drive and overwrote the first 4MB or so.

The FAT filesystem's root directory and many others were blanked but not all files were lost. Norton tools and CHKDSK managed to get a lot of files back but many of the wordperfect documents were in the form "FILE0001.CHK" and no way to know what was in each one other than very laboriously opening all of them and trying to work it out from the contents.

Very fortunately I had an old backup but the problem was to know, out of all the recovered files, which were covered by the backup and which were new since the backup. If I could ignore the files that I could restore from the backup then I only had to load and rename the ones that were new.

CHKDSK couldn't recover the file size since that was in the destroyed directories. So you couldn't guess if some backed up file matched a restored one just by looking at size.

In the end I wrote some perl+shell to get the md5 of the first kilobyte or two of all the backup files and all the recovered files. I used this to match files and get a list of all the recovered files with no corresponding match in the backup. These had to be new files and since there were far less of these I could manually load up each one into Wordperfect, see what it was and give it a sensible name.

This program (don't have it anymore) saved my bacon and served no-one else but me. It took me from despair to triumph and that's why I like it so much.
In Amsterdam a bridge over the water connecting Central Amsterdam with the North is always a hot topic, for decades of talking about it sill hasn't materialized.

A few serious alternatives that were proposed where tunnels for bikes. But they consistently decide not to do it because of safety concerns at night.

Which is hopefully a bigger issue in Amsterdam than Bergen.

I'm a Notjustbikes superfan and love my bike, but container ships are a marvel of efficiency and emissions per kg per km are probably better for the ship.

cyclist: 21g CO2 per km lifecycle - https://ecf.com/news-and-events/news/how-much-co2-does-cycli...

Say I can manage 100kg on a cargo bike, that puts us at 210mg CO2 per km per kg.

Container ship: 16g CO2 per tonne per km - https://8billiontrees.com/carbon-offsets-credits/carbon-ecol...

1 tonne = 1000kg so 16 / 1000 = 16mg CO2 per km per kg

Of course, that will massively depend on diet, conditions, and whether the bike trip was taken purely for transporting goods or whether I needed a workout anyway and it's a two birds with one stone situation. Then again, the sheer efficiency of container shipping might be why I take it as given I can buy some random cheap item manufactured 10,000 km away for a few euro and thereby bring about Jevon's paradox.

I'd still take a EuroVelo route to Canada though if it's on offer!

This makes a common mistake of talking about "energy" in a vague way. The energy used to recycle glass is much less of a problem if its provided by renewables:

https://feve.org/glass-industry/projects/furnace-future/

Apparently the state of the art is that 80% of the energy can be provided by electricity, with various schemes to eliminate carbon from the final 20%

This, like EVs, is part of a virtous loop where electrification leads to more renewables, which leads to more electrification.

The future is lots of little optimisations like that. Another example is returnable glass bottles that weigh less and last longer:

In DDG's defense, some of the censorship was required by law - we don't know if DDG went further than demanded - and Eich himself will tell you that Brave had to remove some results as well.
I’m always surprised by rust’s performance for this reason. The compiler outputs huge binaries, chock full of bounds checks and the like. But performance doesn’t seem to suffer at all from it. On the contrary - I ported some well optimized C to rust and it ran faster.

I can only assume the compiler is marking all the bounds checks as unlikely to fail, and correctly predicted branches must be more or less free in modern CPUs. It’s the only way I can explain it.
Here is the interesting problem that vertical farms never ever tackled...

The amount of actual sunlight that drives the typical tree is more than the amount you can estimate via just a math calculation of the surface volume of the leaves. How does natural sunlight and leaf combination allow this to happen and not non-natural light?

Or in short words the non-natural light the vertical growers were using has more than one problem...

I wonder what if we use more effective wave guides(tubes) to capture the wanted wavelengths:

How does the benchmarking work here? I always find this kind of micro-benchmarking hard. I feel like I want to see results with and without a preceding cache flush. And with/without clearing of the branch predictor state. Other things I find hard are: 1) ensuring that the CPU is running at full(ish) speed and isn't in a slower-clocked power saving mode for some of the test, 2) effects of code and data alignment can be significant - I want to measure a bunch of different alignments.

Does gtest (that the author used) help with these things? Does anything?
