> My method is to vet a random playlist by listening to it during an intense coding session. If I can make it through without getting distracted I add it to my focus playlist.

Very interesting. Up until now I been thinking that I need some kind of noise or non-vocals music just to silence the other distractions to get started, once I get in a "flow state" I think music becomes white noise to me and I barely notice the music playing. Never noticed particularly that anything from any of those playlists on YouTube got distracting in between.

I too have noticed that I end up having to look for some other playlist every few days once that combination of tones starts getting familiar.

Unfortunately, Deezer isn't available globally so can't access that playlist. Thanks for sharing.
Useful uses of dd(1).

There remain some useful applications of dd. These may of course be achieved by other mechanisms, but typically less conveniently.

1. Read a specific number of blocks or bytes from a source:

dd if=/dev/hda of=/root/mbr bs=512 count=1

This will make a copy of, say, your master boot record (first 512 bytes of your first disk drive) and stash it in your /root directory.

2. Read from specific bytes of a file

dd if=mydata skip=1k bs=32 count=1

Reads 32 bytes after the first 1024 (1k) bytes of "mydata".

3. Write to specific bytes of a file

dd if=source of=target seek=10k bs=512 count=1 conv=notrunc

That should write 512 bytes from "source" beginning 10k into "target". (I've not tested this, you should verify.)

4. Create a sparse file. Sparse files appear to have a nonzero size, but take up no space on disk, until data is actually written to them. These are often used as "inflating" dynamic filesystem images for virtual machines.

dd if=/dev/zero of=sparsefile bs=1 count=0 seek=20000M # Create 20 GB sparse file

5. Case conversions. Sure, you could use tr(1), but where's the sport?

dd if=MixEdCaSE of=lcase conv=lcase # Convert to lower case
dd if=MixEdCaSE of=ucase conv=ucase # Convert to upper case

6. ASCII / EBCDIC conversions

dd if=ebcdic of=ascii conv=ascii # ebcdic -> ascii
dd if=ascii of=ebcdic conv=ebcdic # ascii -> ebcdic

When reading to or from IBM data tapes, you might find blocking / unblocking conversions useful. I've done this, but it's so long ago that I don't trust my memory on that any more. Odds are good you'll not have to worry about this.

There are other useful applications as well, though these are not typically encountered very often. Do feel free to explore and attempt these on safe media.

Ok, but if you had 5 x4 drives before, one got full bandwidth from the cpu x4, and the other four would share (equally, I guess) on the chipset x4. Now, you'd get two on the uncontended cpu x4 lanes, and the three sharing (unequally, as you mention), seems slightly better that last time, but not an 'unusual departure' from the previous design; the CPU to chipset link is still very oversubscribed, but now, you can add a second oversubscribed chipset if you want, instead of having a choice between chipsets with different levels of oversubscription (or no chipset, only available in boards that don't expose most of the lanes)

Gravitas Plus: The dark side of Electric Vehicles
Back in the Dark Ages (1968) we had pre-written JCl scripts. I don't think many people knew JCL. We just appended a script to the front of our Fortran card decks. A DD card was the final card. After the frustrating work of finally getting the JCL right, the DD card was always just the "Do it Damn it" card in my mind.
Direct I/O is notoriously finicky. Depending on what filesystem you're using there are apparently alignment restrictions and other corner cases to think about. I don't think it's that `dd` isn't good with Direct I/O, I just think its hard to use.
I worked on an embedded system in the logistics industry where one process drove rendering on screen, and two other processes did a lot of the backend work and implemented lots of business logic.

They communicated over IPC.

This was design this way on purpose, because the back end processes were existing applications. Rather than re writing them entirely, the developers added IPC communication.

Also, they believed it was better for a separate process to crash and just restart rather than showing it to the user and confusing them (the person delivering products to a grocery store).

The whole thing was a convoluted mess.

My advice to you is start simple. You don’t need multiple processes unless there’s a damn good reason. Everything should be a single process.
This is from May 11th, a lot has changed since then.

Observational studies are certainly science. Any claim against that is going to be hard to defend.

The mechanism isn't really at question. But just as sun exposure can kill grass, so to can lack of sun. We know that humans don't do photosynthesis, but it seems reasonable to ask if we do get other benefits.

Note. Is reasonable to ask and study. Is not reasonable to just assume the conclusion.
Agreed. For what it’s worth, I think street skaters should wear helmets most of the time.

The 17ft drop is equivalent to the 80mph example in my post, and should definitely involve a helmet, gloves and impact padding (which can be worn under clothes).

> * it doesn't work if your finger is even slightly wet, so using it while in the kitchen is annoying (like when trying to consult a recipe.) Even if you wipe your hands on a towel or your pants, it still might not work

To be fair, this one genuinely varies per fingerprint sensor. Some of them work under surprisingly bad conditions.

> * it doesn't work if you're wearing latex/nitrile gloves, like when cleaning, or doing car work, etc.

True.

> * it doesn't work if you're wearing gloves, which is a borderline necessity 3-4 months out of the year if you're planning on being outside for more than 5-10 minutes, or if you plan on using your hands for anything while outside. 6+ months out of the year if you're on a bike.

This is really the same thing as the last one, but it depends on where you live. Also, gloves tend to not be great on touchscreens anyways.

My issue with Face ID in particular is that it does not immediately show a PIN unlock, which means when it isn't working quite right you might fumble for a little bit trying to figure out how to get it to stop trying. Also, while it is again totally possible to accidentally unlock with fingerprint if you are not careful, it is hard to _not_ unlock with facial recognition on accident.

(Not to mention, compounding on the problem, the fact that a whole lot of us are wearing face masks in public places right now, and therefore unable to easily unlock our phones with Face ID. Not having a convenient unlock option in public is quite a problem; PIN works, but for example, for payments I'd argue it really isn't ideal, and in public everyone can easily see your PIN when you type it.)

Because of those issues, to me, fingerprint authentication feels like it's mostly a UX positive over PIN alone, whereas facial recognition + PIN is actually worse than just PIN because I legitimately can't avoid a lot of the awkwardness. I mean, anyone can get used to it and deal with it, but I absolutely felt a lot better with Touch ID than Face ID, and I doubt I'm alone on that one.

I see. Prisma does generate a FE client though (PrismaClient) that essentially can be dropped into NextJS API routes (or, more directly, used in the getServerSideProps method on a next js page). Thus its fairly integrated across the stack. (Not trying to jack this thread to peddle Prisma, just a longtime user of it and trying to find similarities).

It does seem feasible one could use Remult + Prisma + NextJS, with Prisma as Source of Truth of DB schema and Remult Source of Truth for Client side data model (although, that might go against the "define once, use anywhere" pattern laid out here).

Really like the project though, great docs and tutorial.
Average monthly high temperature never goes above 90f in Kansas so while it gets a few extreme days a year it really doesn’t get hot for any significant period. https://www.timeanddate.com/weather/usa/kansas-city/climate

The average monthly high temperatures in Las Vegas by comparison are 104f in July, 103f in Aug, and 100f in June. https://www.timeanddate.com/weather/usa/las-vegas/climate

Critically for battery degradation high temperatures when in actual use get well above ambient temperature. So, if you avoid driving in the heat of the day things can look better than local climate suggests.

> The Android ecosystem is full of fragmentation, the same one that Google fanboys argue that Android was designed to fix in regards to J2ME.

I know that there's probably some specific argument that really exists that you're actually referring to, but nobody I know uses Android because of this. Nobody I know was comparing Android to J2ME either. More casual users tend to use it because they dislike iPhone and possibly feel limited by it. More advanced users tend to use it because it's generally more customizable, open source and at least in the past, was much easier to mod and patch.

It is true that unlike Windows devices, every Android phone is a snowflake. That's a real problem. But for many people, they don't really care about that problem, only the derivative consequences, like not being able to upgrade their phone to the latest version, or security issues that result from shoddy OEMs. And frankly, users are right to not care: it is not a given that these derivative problems can't be solved in a different way that is satisfactory.

(And yes, of course, many users today buy Android devices because they're cheap. But they still had to cross a threshold in the market before they could become the mass market success that they are today, and that happened with mostly enthusiasts.)

Try meditating on it. Sit quietly with yourself for 15 minutes, shut your eyes. Ask yourself what different parts of you want to do. See if you can access the part of you that knows which one you’d like to do.

Or try asking yourself: which of these options do I feel like I should do and which one do I feel like I want to do? And then do the one you want to do.
You are here missing only one very simple but important fact. Russia nor China are not superpowers. China may become one soon but it is not yet. Russia can be as concerned as it likes to be but if it steps over the line, it will get its ass handled back to it.

Maybe the pricing you expect will be at a level that I am going to ignore anyways, but I think AMD may be reducing features and pci-e lanes because Intel has been doing just fine not giving away the kitchen sink in that area, at least from what I observe. Isn't intel kind of dragging their feet with any new HEDT lines?
Taxing the wealthy may or may not be a good idea.

Shrinking the money supply is an awful idea. If money supply shrinks is decreases investment, increasing unemployment. Commerce stops (because people assume there money will be worth more in the future so they reduce spending) which increases unemployment more.

There's a reasonable debate to be bad about tax rates for wealthy people. I don't think any economist on either side of politics thinks decreasing money supply is a good idea.

Sorry, I find this ridiculous.

The boomers heading into retirement situation is a reflection of 40-50 years of economic policy and has no connection with recent "cheap money".

Actual investment in single family and apartment housing is almost entirely tied to its low risk/return ratio compared with (the perception of a lack of) other options for investment at this time. The money sloshing around for investment is as much as function of the effective privatization of retirement funding as anything else.

The short term rental market is in part the perfect expression of how a relativel small number of wealthy individuals can totally distort a market to follow their own preferences, and reflects income/wealth inequality and lack of regulatory enforcement (they're freakin' B&B's people!) as much as anything else.

Cheap money has almost nothing to do with any of them.
This reminds me. I recently saw some idiots on one wheels (electric "skateboard" with a single wheel) in full stunt motorcycle garb (body armor, shin guards, motorcycle helmets and all) on a busy mixed use trail, going at least 30mph and doing stunts.

However, banning staff from wearing bike helmets is idiotic.

> Not so sure “sufficiently motivated” folks could just learn this.

Pretty sure the ability is there in most people. Not that many do it, but the potential is there. All too many people are disengaged and trapped into apathy by their experiences.

> I have what I call my “fugue state.” It’s a fairly “timeless,” focused, self-centered state, where “everything flows.” I get a lot done, when in this state, but many hours can go by, and it’s exhausting.

Yup. That state was dubbed "flow" by Mihaly Csikszentmihalyi in 1975:

https://en.m.wikipedia.org/wiki/Flow_(psychology)

Among "normies" flow seems to often have a physical activity component, and is more common among athletes, musicians, artists, surgeons, and similar professions. Many gamers would recognize themselves in your description as well. The more purely mental version you experience is less common, though it isn't restricted to pursuits like math or coding. Writers (of types as diverse as journalists and fiction authors) can experience it too, for example.

> I also get pissed when I’m yanked from that state. I get quite cranky. Lasts for about half an hour, afterwards.

Oh my yes. I can get cranky enough to lose the whole rest of the day. Also note that the writer that gets cranky when interrupted is practically a trope.

It is worth noting that a state of flow, while extremely productive, may not be the best state for improving your skill (although it does allow polishing skills smooth, as it were), which is better served by deliberate practice of activities that are a just bit too challenging to allow entering the flow state (if they are harder than "a bit too hard", it may help to do it at half speed, which can feel a bit wierd for something like coding).

> That kind of thing makes it hard to play well with others. When I was a manager, I didn’t have that issue.

Well, there is such a thing as "team flow" but it doesn't seem to be cultivated deliberately much outside of team sports, improv, and group music. Something similar can occur in group brainstorming sessions, though.
Now if flutter would learn all of that and stop trying (and failing) reproduce it! Guess what? OS Level and browser level spell checking doesn't work in Flutter because it's rendering pixels instead of OS text input / HTML text input. And a ton of other issues that will likely never be fixed. It almost makes we wonder if Flutter's goal isn't good UX but rather user control. If it's just pixels it's much harder for users to copy and paste, quote, scrape, etc....

16 direct dependencies, 39 transitive dependencies, and nearly 7000 lines of code -- for a package that handles flags and config files. I can't help feeling that frameworks like this are a little overwrought. It's the sort of project that succeeds because thousands of people just need something that works, right away, so they search for "golang config" and click the top result. Whereas if you can afford to slow down a little, you might find that the stdlib (with a bit of glue) is a perfectly serviceable option for the majority of apps.
