I think you are exactly right. The customers who want the bazaar with lots of parts are already their customer and will continue to be their customer regardless of a brick and mortar store. This is trying to attract a new customer.
Yes, as the predicate defines what you want it to do, not how.

The database engine will transform your declared goal into an execution plan (query plan), which defines how it will achieve what you want.

Apparently functional programming is considered a form of declarative programming. That doesn't make much sense to me, but I guess relative to writing assembly or C it is declarative. The distinction seems arbitrary, because even C and assembly contain abstractions for more complex operations taking place in the OS and in the hardware.
No. The Select-statement is not evaluated until necessary, i.e. until ToArray() is called.

a simple arithmetic computation shows that Europe has 750 million people, and the world has 8 billion people. That's 1/10 of the population. We neglect about 90% of people in... anything. South America has 500 million people, so they should get a comparable share, and Africa has 1.2 billion.

So just by simple fractions we know something is off. A more careful study by subject and region could be required.
I suppose they quite like the fact that if you build something on Rpi you have to buy from Rpi and can't go on to design your own board and buy the SoC from Broadcom.
Yes, I stated that in my original question already.
I'm not sure I'm a fan of their app rating system. The first review on the page, for the FODMAP Diet app, shows a screenshot that using practically indistinguishable shades of red and green but shows a rating of "Works for the Color Blind". Turns out that's only because there is an "Color Blindness Assistance" buried within the settings.

While it's good that the option exists, adding an optional "color blind mode" is the wrong way of thinking. Designs that include multiple distinguishing cues - color, shape, size, symbols - are easier to use for all users.

A site like this should push for a higher standard. I'd rate this app a C - passable, but not ideal. If they would just set the "color blind" mode on by default, it would be worthy of the full grade.

An interesting observation in the article is the data structures DSL that the author goes into quite a bit of detail, which is essentially what most Clojure/Lisp developers also talk about.

Basically the author points out a lot of benefits of using the native serialisable data structures of the language itself to model the domain, instead of creating a separate representation which has to be parsed, optimised, evaluated, etc. Lisp users just take the same idea one step further by having the "host" language also be represented using the same data structures, instead of just the DSL's.

As Alan Perlis said, "It is better to have 100 functions operate on one data structure than 10 functions on 10 data structures."
I must be missing something because Google collects more information from more sources for more advertising. I'm more worried about Google.

Are you implying the use of context when you say that hooks allow you to re-use state between components?

Legit question because I don't know hooks very well. To my understanding, hooks are just syntactic sugar to use and update local state in a function component. How does that help you share state between components?
It is incredibly relevant to politics today. Galvanising people's anger to get them to support something completely unrelated that's not good for them at all, is something we see constantly. In Brexit, in Trump, but also in many other cases. People are easy to manipulate. And instead of a warning, people are treating Orwell's books as an instruction manual.

The problem with analytics is too much info or not enough info. At each employer, I usually do my best to get involved with the analytics portion of our applications. Apart from just finding it interesting, I also like to try and interject some sanity. I've seen managers walk in, puff our their chest and say, "Just collect everything. We'll sort through it here. Make it happen." After they walk out I engage everyone in conversation about that and try and let them know that we should actually be creating a list of questions we want answered and work from there. Collecting everything is almost always not the right idea.
This is one of the most brilliant and succinct put statements I have read in a while. However, do you have any pointers to underpin your statement?

Although the engineering behind getting a good sound out of the PC speaker is fascinating. Still wishing the PC standard from the get go had included sound as a first class citizen.

I think this decision back then still ripples through the machines today and sound never truly feels like an integral part of the machine on Windows (Realtek audio driver) and you'll never have the feeling of a built in boot sound on your machine which felt so good on Macs till it was disabled recently.

It's not like computers didn't have good sound back then either compare the Lotus III example [0] from the article with the same on the Amiga hardware from around the same time [1]

This is a misleading description. The service was not "secret" at all. Until the recent debacle [0], you could even demo the location tracking by entering your own phone number on the LocationSmart.com.

I would hardly call that a "secret company."

I cant speak for anyone else, but I got into programming from using Linux. The fact that you have all these languages just there, and its all an open system etc really encourages you that yes this is something you can do, and not just toy examples. I've seen the same point made about boot to Basic, 8 bit computers also.

I don't by contrast program on my phone because it just feels like a gimmicky toy.

I'm not saying the raspberry pi is anything like a phone in this regard, but in does have a limit to how far you can dig, and that's a real shame.

Is it limiting to the scratch programmers? Probably not, but the Scratch programmers read about and move on Python, who then move on C. But if the boot process isn't open, there isn't anyone to write about it, so people don't discover it. Which for an educational endeavour is problematic.
Thank you very much! I always wanted to check out the PDP-1 and play Spacewar. Because I'm on the wrong continent, the only way to do it was to build my own :-)

There is a follow up - it can also play music, just like the original could. Check it out: https://www.youtube.com/watch?v=ROPyR-tV7A4
I had a minute to check it out over lunch - most of the floorspace is dedicated to demonstrating what the raspberry pi can do at a high level. They had stations for coding, gaming, sensors, etc. but only ~1/4th of the space was devoted to inventory. While they have a decent selection of Pis, sensor kits, and accessories, it's definitely not a replacement for Maplin. Additionally, Already__Taken seems to have been correct about the level of knowledge among the staff - not everyone working there was technical. This is definitely aimed at the general public.
Or they quote the lifetime figure for a single LED, but then wire up a dozen or more in series to make the light. Any one of them fails and the whole assembly goes dark.
> I can provide my body with as much energy as it wants to consume

No, you can't. All energy that your body uses transforms to heat. The amount of head your body can handle is fairly limited. Bigger bodies perform substantially worse since they have a smaller volume/surface ratio. Even heatsinks such as elephant ears just provide a small help.
Soon Bladerunner will be one of those movies. I rewatched it yesterday and was astonished to see that it plays in "November, 2019".

As I recall, Facebook was allowed to buy Whatsapp in France after they promised not to share user data between the two services. I think Germany had similar objections, but now Facebook is ignoring that agreement which always annoys governments.

Facebook even got a $122 million EU fine for same issue https://www.engadget.com/2017/05/18/facebook-european-commis.... “After months of deliberation, the European Commission has ruled that Facebook intentionally mislead officials over its ability to utilize data following its acquisition of WhatsApp in 2014.”

Yeah, caffeine gives me a short fuse like nothing else.

As little as a coffee in the morning would basically make me prone to fly off the handle due to the most insignificant, trivial little things. Cost me and my wife many hours spent in pointless discussions and unnecessary arguments.

Don't get me wrong, I love coffee, but I have to treat it like you would a recreational drug. Only to be enjoyed when the set and the setting is right.
There's one right turn I take off a rural road where the telephone poles are 200ft apart. I usually try and see how fast I can stop if nobody is around. I've been doing this for years. The difference between bald Douglas all-seasons one week and the same tires but brand new the following week is the difference between ~400ft@80mph (approximately textbook stopping distance) and about 350ft. I could probably shave off more distance if I had ABS and could plant my foot and make the computer do all the optimization for me.

I'm not trying to assume best case. I'm saying we should not assume worst case either. Most sources do the latter because most sources seek to coax everyone into driving conservatively (which is not a bad thing).
Yeh, I terribly unfortunate the beacon of liberty has chosen to embrace censorship..

I'm not saying I agree with any of the above opinions. However, I think it's pretty well documented that depending on your political persuasion, ideological bend, or ability to put aside reason in the name of "completed science", some opinions definitely hold more value than others. I for one am glad reddit has always appreciated that fact.

There's a strong case to be made that the censoring in certain countries like China, is actually helping the masses make sense of their world better.
>A shock from a DC supply will cause heart fibrillations at lower voltage than AC, because of the way muscles receive signals from nerves

That is opposite to my understanding. The extra shock hazard of AC vs DC was an argument used against AC power distribution back in the day. The 50V limit is to prevent shock altogether.
Is it singling out Apple or did they just hear about it happening on Apple and decide to write that up? Sure they could have investigated to see if it happens on other platforms, but you gotta get the story out there fast otherwise someone else will.

1. Nothing. Which is what makes this seem soooo shady, and both parties refusing to give even a surface exuse.

2. They're not trying to influence policy, but young impressionable Redditors. Even a 1% change in opinion can be huge at key moments, narrative framing is still effective, even things like the semblance of disagreement can be massively persuading.

I've witnessed my own national subreddit turn from a great little corner of the internet to a shill-ridden shithole. It probably only took the coordination of two or three real full-time people, some coordination on mod replacement, and clever software. But it has been remarkably effective.

The same tactics that worked for my little country would probably work as well or better in other subreddits, and there's no real creativity required to pull it off.

> Looking approachable is a pretty key component of that.

Agreed, the other key component though is actually making their machine and software/hardware approachable, smooth, performant and reliable. Which they haven't really put any effort in to since they started.

I really wanted the dream of an affordable computer for kids to be a reality but at the end of the day when the $35 just isn't as performant as a budget tablet around the same price then kids are going to just end up with tablets and never have the opportunity to crack the machine open.

If the product doesn't live up to the sales pitch of the store, then the product is just going to get returned.

The difference is referential transparency: In declarative programming, an expression always returns the same result, no matter where and in which order you use it. Contrast this with an expression like a += 1; in C, which returns a different result each time.
> simply adding a kernel patch won’t fix all of the software

That's tautologically true, but something like the RT preemption kernel patch is still a basic requirement for a truly responsive system. Once that's merged, you then have buy-in for that use case and can start fixing all the things that are broken in user-space, as well.

Additionally, there's a lot that can be fixed by simple tuning. There's no excuse for UI input locking up when a system is low on RAM, for example. Any tasks that are critical to input on the system's console-like channel (whatever that is - it might be a serial console, UI graphics, a network connection or even an audio input subsystem plus some speech-recognition AI) should be running with elevated priority, so that (1) they're always responsive, no matter what, and (2) when the system starts thrashing, they can still grab enough of whatever system resources are available (RAM, CPU, device I/O), so that the user can survey the situation and kill the offending process. Linux distributors are dropping the ball here - this sort of system-wide tuning is their job!
Is the Swedish case the same even for non-high demand fields? I suppose by definition every job (irrespective of compensation or skill needed) would be a high demand field if it takes 12 months to fill; at which point I suggest that what Sweden has is a demographics problem, not a strong economy.

> flickering at over 50%

what does that mean? Duty cycle is 50%, frequency at something Hz? Not being snarky - curious whether there is some kind of standard that your tool compares against.

A duty cycle 50% (or any percent really) isn't bad in itself, it's the frequency that is the culprit. Too low PWM freq and you'll notice it.

Maplin mostly stocked poor quality products and massively overcharged.

I think charging x10 what a product would cost on eBay is reasonable. But often you’d be charged x100 to x1000 times more for cheap components (resistors etc.). I mostly ended up buying larger packs of parts which might come in handy, because I didn’t want to be overcharged to that degree.

I wouldn’t mind so much if they stocked good quality soldering irons (e.g. Hakko) or good quality hand tools. But they didn’t.

It’s a shame there are no good electronics high street shops left, but I’m not particularly sad to see Maplin go personally.
> Originally Volt app was written in Go, but after a couple of weeks of development I decided to re-write it in C for two reasons: easier integration with existing C graphics and UI libraries and much smaller binaries. The app size reduced from ~5 MB to ~100 KB.

I'm always curious when people complain about binary sizes. Was there some reason the binary needed to be small? Or just based on some sense of 'largeness' and 'smallness'. It seems to me like rewriting in a 'less productive language' to save a few mbs of binary size that nobody cared about anyway is a pretty big waste of time.

I don't mean to come across super critical, there are cases where binary size could be really important. Say you're on an embedded platform with minimal memory. I just don't /understand why it was something worth optimising over here... especially to the point of a rewrite

to learn assembly I wrote a "PC speaker clicker" that just strobed the click register and had a small timing loop to play A440.

A person in the room spoke up when I played it- "that's not A440, it's off slightly. Oh, and I have perfect pitch- it's about 439".

I had a small bug in my timing routine that made the pitch slightly lower, which I fixed.
They don't care so long as they can spin it as the buyer's fault. Early on, before the Pi even launched, they encouraged grassroots marketing campaigns which (amongst other things) promoted the Pi as a consumer-y kind of home entertainment device. One of their forum members pointed out that this might lead to disappointment because it really wasn't a plug-and-play consumer device and required a certain amount of technical knowledge, and his concerns were roundly dismissed. Then after it launched, their staff complained that people who wrongly thought of it as some kind of consumer entertainment device were unfairly giving it a bad reputation because they didn't have the technical skills to get it working.
I watched Bladerunner again recently (set Nov, 2019, so technically it doesn’t belong on this list just yet). I’ve seen it dozens of times, but for the first time I was struck by the fact that the flying cars in it are still driven/flown by humans.

Then I couldn’t think of any stories set in the future with self-driving cars, flying or otherwise. It’s sort of ridiculous at this point to have a human pilot in any futuristic form of transportation, isn’t it?

But I guess all those space battles would be pretty boring without humans to run the ships.
