> "These are systems that focus on generating beautifully typeset documentation without allowing the author to arbitrarily order code."

The previous sentence was: "When I look around at the legacy of literate programming, systems to do so-called semi- or quasi-literate programming dominate." Semi- or quasi- being intended to distinguish with classic literate programming as in CWeb.

I usually try to go out of my way to assume that if someone misunderstands me it's a failure of my writing, but in this case my post is filled with Knuth's original CWeb programs. It didn't seem realistic that you missed them all, or that you thought I missed that CWeb permits reordering in spite of having read so many CWeb programs.

And then you make this new jab about me not having read any literate programs, in spite of me showing repeatedly in the article that I went all the way down the list at http://www-cs-faculty.stanford.edu/~uno/programs.html. Are you sure you read my post?

Thanks for the pointer to http://mmix.cs.hm.edu/local. Not immediately obvious that it cares about literate programming, but I'll take your word for it. I'd appreciate intros to anybody in that group with experience reading literate programs (email address in profile).
If that's true we are moving into a scary world pretty much like 1984 where everything you do is monitored all the time. Add voice, face recognition, surveillance drones, cheap data storage and AI to the mix it seems pretty soon everything you do in a public place will be recorded and analyzed. And all this can be done fully automated.

I hope people will recognize that some laws need to change. Surveillance makes sense in some cases but it should be hard and expensive to do.

"Does Flatpak address this problem at all?"

Yes, it seems to. As I understand it, there's the concept of a runtime, which is kinda like an OS installation (but it's an immutable image type thing that gets distributed identically to everyone who wants that runtime), which packages can be built against, meaning the application package only needs to include its own specific dependencies that aren't part of the runtime. So, similar to how one might build for Fedora 24 now, one could build for a Fedora runtime, and any user who had that runtime wouldn't need that image to be downloaded...they would already have it. So, if you only installed packages provided by your OS vendor, the size of things wouldn't change much.

Where things begin to look different is that any Flatpak can be installed on any system that has Flatpak. So, don't have a runtime that an app you want is built against? No problem, this'll grab it and set it up, transparent to the user. And, next time you want another package built against that runtime, it won't need to add it. This is like being able to install anything from Debian repos on CentOS, or vice versa; it's also like being able to install from Debian stable, unstable, and testing all willy-nilly without fear of it breaking other packages.

At least, that's how I understand it...but, that'll be many years coming. This is such a fundamental shift in how we think about packages that it's unlikely to catch on quickly. But, I'm a package manager nerd, and I can't believe I didn't realize this was underway; I would have started following it earlier. I love this idea.

Well at least on Linux, by default almost everyone (using consumer drives) has their array in a very common misconfiguration. And this leads to raid5 collapse much sooner than it should.

The misconfiguration is the drive's SCT ERC timeout is greater than the kernel's SCSI command timer. So what happens on a URE is, the drive does "deep recovery" if it's a consumer drive, and keeps trying to recover that bad sector well beyond the default command timer of the kernel, which is 30 seconds. At 30 seconds the kernel assumes something's wrong and does a link reset. On SATA drives this obliterates the command queue and any other state in the drive. The drive doesn't report a read error, doesn't report what sector had the problem, and so RAID can't do its job and fix the problem by reconstructing the missing data from parity and writing the data back to that bad sector.

So it's inevitable these bad sectors pop up here and there, and then if there's a single drive failure, in effect you get one or more full stripes with two or more missing strips, and now those whole stripes are lost just as if it were a 2-disk failure. It is possible to recover from this but it's really tedious and as far as I know there are no user space tools to make such recovery easy.

I wouldn't be surprised if lots of NAS's using Linux were configured this way, and the user didn't use recommended drives because, FU vendor those drives are expensive, etc.

> "It takes a lot more than a kickstarter campaign to fire up a card program like Osper or GoHenry."

No, it doesn't. At our startup we managed to get on a prepaid program without funding (we are a London based startup). Infact, through negotiation we even got the sign up fees waived.

And, we did all that before we had ANY funding.

> "Give Marqeta a call and check out their fee structure."

We did call Marqeta but they're not yet in the UK. Can't discuss pricing because of the NDA they make you sign but I can tell you that we didn't have to pay anything to Marqeta during development.

But, either way my issue is that they kept blaming their banking partners for the failure of their startup instead of taking an actual critical look at the mistakes they made.

> Pilots found that jets’ systems would shut down midflight about once every three or four hours and have to be rebooted.

> But the new, improved version of 3i is a significant improvement, according to the JPO. The new version showed approximately twice the level of stability as the previous load, Block 2B, and three times better stability than the original 3i software

Does that mean it "only" needs to reboot once every 6-8 hours? If that's considered stable enough to sign off for production, does that mean they will simply reboot before each flight and just hope for the best?

If you believe the Berkeley people (I don't, but the sheeple do), most Spark workloads are CPU bound not IO bound. But irrespective of that, if most of your data is in a columnar data storage format, there's no gain (only cost) in having your FS also try and compress it.
JBOD is considered best practice for Hadoop. That's why we're looking at RAID0 and RAID5 - we're researchers :) Actually, MapR recommend using 3 disks in RAID0 as volumes.
Chrome did not previously rely on a dynlinked system library for the negotiation feature. Now, evidently, it does.

In making this transition, Chrome experienced a massive practical regression for many users, precisely because the dynlinked library is not sufficiently up to date for many people.

“They give their young workers Ping-Pong tables and take away their constitutional rights,” said Cliff Palefsky, an employment and civil rights lawyer in San Francisco.
This is why programming languages that support nesting really help in some scenarios. It's great to be able to write functions inside functions, with or without captured variables/bindings. (I know a tree isn't all graphs, but it works well for many scenarios.)

When I start on a new program in F#, I usually just start with one main function and keep typing straight on down. When I want to re-organize it into a module, it's usually nearly as easy as writing "module" at the top.

Without this, one is encouraged to either not abstract properly as the overhead and context for a new top-level function is too much, or you end up with free-floating functions that don't belong there and only have a single caller.

I'd call that a fundamental fail - hitting the brakes has to be a more nuanced event than simply disabling autopilot.

Then they go one to essentially disavow autopilot - "...but it does not turn a Tesla into an autonomous vehicle and does not allow the driver to abdicate responsibility."

There are air incidents in which the pilots were unclear about whether their autopilot was in charge or they were. That's extremely dangerous.
Yeah, I just noticed that and edited my comment. To me, that just makes the dependencies more coarse-grained -- now you have this artifical 2-level system of apps and runtimes. You've just recreated the same problem again with bigger blobs.

So I can't see right now how it's going to work. I feel like it will flame out. But this kind of thing involves a lot of social problems in addition to technical problems, so you never know.

EDIT: A more concrete example. Apache, nginx, Python, Ruby, Perl, node.js, Erlang web servers, etc. all depend on OpenSSL.

OpenSSL is 500K lines of code. When an important update inevitably comes out for it, what happens? Are you now updating 10+ runtimes that are 1+ GB each? Do they use differential compression at all?

I don't see how the two-level hierarchy really solves any problems. It could be the worst of both worlds (very fine-grained sharing vs. duplicating all dependencies)
That's continuous delivery for you.

That's valid, I'm sure I've done the same more times than I know. My general rule is if it's from a brand or site I know I've interacted with or generally recognize I'll spend two seconds to check the unsub options.

If the unsub requires me to log in first, I mark it spam instead. If the link looks fishy and/or I can't readily discern it's of any quality it's spam. If I have no clue why I could've gotten the message it gets flagged for sure.

Luckily for me I get very few emails per month that I don't know why I would've gotten them, so it isn't a painful exercise to give them a chance to not get flagged.

I use Unroll.me[0] to manage the messages I do want to get, but want to check on my own time and I don't want them sitting in my inbox. I'm sure there are other types of services, but I'm generally happy with what they do. They also can manage a lot of the opt-out features as well, not sure if it 'protects' me any more than doing it myself though.

Your tool is exactly what i think makes the most sense so far in having go work with DB. It's type safe (assuming the tool is correct), and doesn't add complexity in the code or complex and magic libraries.

It also makes the database schema the source of truth for a system, which makes the most sense to anyone that has really worked on complex systems (most of them having the DB be accessed by multiple subsystems, written in different languages).
Yes. Many times yes. The cost of launches is on the order of a few hundred million.

Military satellites often cost a few billion. Losing a satellite is, by far, the biggest risk during a launch. The launch cost itself is non-trivial, but a small fraction of the overall mission cost.

I agree with you. Touching the brakes should not completely disable autopilot. The aviation industry has a term for this sort of error, a Mode Error. If it is unclear what mode the vehicle is in (semi-autonomous mode, or full manual mode) there will be times when the user assumes they are in one mode when in fact they are in the other. Having the change in modes be as subtle as tapping the brakes makes this type of user error very likely.

I think Tesla needs to impose some very clear indicators when they are in autopilot mode vs manual mode (lights on the A pillars, etc.). They also need to revisit what exactly disables autopilot mode. Tapping the brakes should not disengage auto braking for example, only accelerating should do that.
What if the content I paid for by viewing ads wasn't worth it? Am I entitled to a refund?
I don't understand the real value in this. They take a bunch of BGA parts + passives and put the dies in a bigger BGA that approaches the same PCB area?

If someone has the manufacturing capability to put down one integrated BGA part, then they have the capability of putting down the DRAM and processors just the same as well as the 0201s or whatever passives to support it.

Only thing it seems to do is enable quicker prototyping by avoiding having to get things like the DDR memory traces correct. And a shorter BOM.

On the flip side, single source supplier, fewer memory options, fewer chip configuration options, etc. Places with the manufacturing capability of BGAs and 0201 probably aren't distracted much by 50(guess?) additional BOM line items and the reels of parts to realize that.

Also, how many hackers are actually putting down BGAs like this when you can buy a properly routed, tested and assembled BeagleBone for so cheap? I know a few are, but they are the 0.1% perhaps? All the makers are rocking Arduinos and Raspberry Pis and can't even spell B-G-A.

It is a political isue. In Germany the average income is at about 30.000,- Euro.

So many people cannot aford any EV, even the cheapest. So they are excluded from any subsidies.
But they pay their taxes. They work for the rich people, the company owners. They work for their profits, so that the rich are able to pay taxes or transfer the money to panama and avoid paying taxes.

The party SPD is a working class party for those people earning about 30.000,- and less.

And now consider to explain those people, that they pay taxes to subsidies the drives for the rich people.

According to earlier articles about this issue, planes currently in wide use need to be 'rebooted' at a similar frequency, it's just specific subsystems that get rebooted (I think the F-35's former problem was a sensor), the planes keep flying, and missions don't often last that long anyway (IIRC all the details).

EDIT: Heck, I'll just copy the meat of it here:

http://breakingdefense.com/2016/02/bogdan-predicts-f-35s-for...

The toughest problem the program is having is matching the timing of the aircraft’s fusion software with its sensors’ software. “As we add different radar modes and as we add different and capabilities to the DAS system and to the EOTS system, the timing is misaligned,” and then you have to reboot it. Bogdan said he’s aiming for eight to nine hours between such software failures when a radar or DAS or EOTS needs to be rebooted, which is what legacy aircraft boast. Right now they are at four to five hours between such events. “That’s not a good metric.”
If that's true we are moving into a scary world pretty much like 1984 where everything you do is monitored all the time.

Well, not everything. Plant a GPS tracker on a police car or a bug in the restroom at FBI headquarters and you'll soon discover some troubling asymmetries in the modern post-privacy paradigm.
