> ... little-a agile is understood to be a thing you grow towards with constant improvements and changes to both the process and the system being developed based on frequent, ideally continuous, feedback.

Agreed, and I have no objection to the feedback and continuous improvement aspects of agile development. Or anything in the Agile Manifesto, for that matter. In my experience, however, when projects "go Agile" they tend to cargo-cult simplistic, visible changes like Scrum instead.

> Boeing, in my experience, didn't want to change their processes...

Yes, this is generally the issue. On the other hand, those processes are strongly influenced by industry standards such as DO-178 which codify "tried-and-true" practices established in the early days of software engineering—it isn't just a matter of corporate culture. It's not mandatory to follow these processes, but if you do then certification is basically assured, which is much simpler and more reliable than arguing the case for a brand-new process with no established history in the industry. For the most part these standards treat software as just another "component" to be integrated into the hardware, like an extra-complicated combinatorial circuit, rather than what it is: the design of a iterative, stateful process to be carried out by the hardware during flight. Novel development and certification processes are a huge risk; understandably, no one wants to go first, even when they agree that change is needed.

That's simply wrong. Renewable energy for electricity is at 46% last year. Up from 6% in 2000. Coal has been declining a lot from 2000 (when the Energiewende startet) to today.

Alfred would not be the correct analogy to Gaul/Rome. The Gauls were "Celtic" like Arthur's Britons. They were both facing invasions.

Alfred's French analogy would be Charles the Simple, who had to fight off the Norse invaders and made a treaty to give them Normandy. Though, it has to be said, Charles the Simple had a much better time of it.
Here's the thing: most books, for most people, don't need to be absorbed or understood in their entirety.

If you're a professional in your field and ought to be expected to be able to write a similar book? Then sure, you should understand it 100%. But this is a very rare circumstance for most people.

For most books, the reality is that you only need to know the Big Idea and its main justifications. Or that, depending on your needs, there are a few additional details that might come in handy. But that reading the whole book a) really ensures you'll remember the big idea and its main justifications, in a way that a one-page summary you might totally forget later, and b) lets you skim for specific details that might be especially relevant to you personally.

You shouldn't generally feel guilty that you don't remember enough from a book. You're not supposed to. (Again, unless you have a very specific and necessary professional reason to.)

Fully understanding a book might take 100 hours. In that time, you could read 10 other books in 10 hours each and get the main gist of each. Which one do you think is going to be more productive for your life?

Most of these books are very poorly written. Smith's Wealth of Nations, as an example, is mostly very well-written and abysmally bad through the minority (Marx/Keynes probably the opposite). And meaning isn't really constant either, you read something and then come back to parts of it.

Look at it this way: say you make $100k per year. This means you’ve got $1M coming over 10 years! If you leave after 2 years, do you feel like you are giving up $800k?probably not. So why not think of RSUs the same way?

That’s how I think of RSUs: they aren’t yours until they vest: they’re just like future pay, so you’re not really giving anything up if you leave “early”.
Hi Andrew- of course I've been following Zig. Thanks for your trailblazing efforts in the "C replacement" space.

It's true that symbols in 'false' preprocessor blocks will not be caught. Maybe it's best said "if the compiler will find the symbol when you compile, then the symbol renamer will find it when you rename". Which is definitely not true for most symbol renames I dare to attempt in C++ IDEs.

New Year’s Resolutions for Introverts (2017)
You might get away with pissing on Carnot's grave once - but twice - never. By that I mean the energy of compression is lost. A compressor is an analog to an internal combustion engine - in reverse. You put in energy via amotor and compress the air. Unless you can use that heat of compression it is lost. Then you run another analog to an internal combustion engine - in reverse.
https://www.google.com/search?ei=jFgWXoCkI474-gTJspPoDQ&q=en...
Extract:-
• Is compressed air free?
No, compressed air is not free. Although "it's only air," compressed air is actually very expensive because only 10 to 20 percent of the electric energy input reaches the point of end-use. The remaining input energy converts to wasted heat or is lost through leakage. For example, to generate 5 CFM it takes 1 HP.

So 10-20% for the compressor.

Then the expansion:-
https://en.wikipedia.org/wiki/Pneumatic_motor

sir motors are in the 60-65% efficiency range.
Then the electric motor to drive the generator is about 93% efficient (some as high as 95%)

This string of 10-20% plus 60-65% plus 93.95%

Gives a net range of 5.58% efficient all at low end of range to about 12.35% at the high end.
At best you lose 87% and at worst you lose 94.5%

But this is wasted energy anyway, but it has to pay for manitanance and staff etc, so in the worst case it is terrible and the best case is sub-marinal.
Looks like a free energy racket to me?
God this would be great if we could get an Android color e-ink reader released so I could do Safari Books.

There are still tons of applications:

Digital photo frames that cycle throughout the day, dynamic posters and murals with art that changes with the time or viewer, refreshing price labels, clocks with minute resolution, data visualization over large time intervals, informational displays...

You might not even have to paint the entire screen at once, but can perhaps update only the dirty regions.

Not everything needs to display video or respond in real time to human input. There's so much painted in the world around us that could have value added by letting it refresh on the day, hour, or minute.

You don't quite need an air-gapped multi-key cryptographically secure system, but a few checks by various parties that articles have been copy-edited, fact-checked, verified for browser support and accessibility, and approved by an editor would seem to alleviate a lot of embarrassing publication errors.

But that's not how the process was described. The first book is apparently only for vocabulary, the second for diction (not sure about a better term for this), third for basic concepts, fourth for application, and then finally a holistic understanding of the subject. If the case was looking at various ideas, I'd agree with you, but if the first book only "gives me the important words" and the second "gives me the paragraphs that show how the words are used" then it's not really giving you different perspectives as you're still very much in the "understanding what the book is talking about" phase.
> An advanced GC requires having "write gates" inserted into the generated code

This isn’t strictly true. In particular it is possible to design a GC such that write barriers are implemented in hardware (these days using the mmu not dedicated hardware). It’s also possible to write a (non-incremental non-concurrent non-parallel) gc that uses no write barriers: just stop the world, collect and move.

The mmu-for-write-barrier technique I’ve seen is to keep pointer colour in high bits and map the same physical memory onto n copies of itself in virtual memory (so you don’t need to mask the colour bits away before dereferencing). When the mutator tries to write to a black pointer (or maybe pointers are coloured by whether their targets might have moved?), the gc gets a memory exception and can ensure that the invariants are maintained. The general assumption is that this doesn’t happen very often in most programs. I can’t remember the name of the system I’m thinking of but it’s one of the new GCs being developed for java.

An alternative method to avoid a write barrier is avoiding mutation in your programming language. This makes GC simpler. There are other advantages and disadvantages

It could become feasible with a custom UI. You could have a version of vim or emacs that doesn't even "scroll" your code conventionally, but just gradually rewrites lines starting from the top down (or from the bottom up when scrolling "back"), sort of doing away with a unified viewport - this would at least address the most common operation in a dev environment that currently requires quick full-screen update.
> If they are being ordered to carry out a first strike, they have no idea of whether or not that first strike is reasonable, or not.

A first strike of nuclear ICBMs is never going to be reasonably justified. Even if we ignore the fact that there is absolutely no basis for speculation that the POTUS would ever order such a strike, there is no basis to speculate that silo personnel will comply with an order that is clearly unlawful, a crime against humanity, a war crime, and risks the complete destruction of human civilization. Out of all speculative scenarios, this has to be the least plausible.
I'm optimistic because devices like smart phones and smart watches are things that benefit from having very low idle power when just displaying mostly static info but require a much faster refresh rate in active use. Being able to read them easily in bright daylight would also be a great plus. That's a good market.

Even laptops would probably benefit from it, when you're typing some text or reading a document you don't need 60fps refresh rate (especially if you can only refresh portions of the screen). That might save a significant amount of battery.
I've been waiting for something like this to use as a digital photo frame. It lets you have see all your photos without having it glowing at you when you go to bed.
I've long thought that it would be great to replace all kinds of signage wit eInk. Time tables on public transport, any kind of announcement that's typically printed on paper,... There's lots of stuff with a low refresh rate (sometimes in the order of months) that could benefit from being easier to update, but that isn't worth replacing by power hungry, overly bright, hard to read LCDs. Hell, there are a lot of cases where LCDs are used wher eInk would be a much better fit. Things like meeting room reservation screens, for instance.

With largeish colour displays, maybe that'll all finally become a reality.
Well, we're planning on porting Corundum to the NetFPGA SUME hardware at some point in the near future. Should be relatively straightforward as the PCIe interface on the Virtex 7 is the same as on the Ultrascale parts.

NetFPGA does have a NIC reference design, but AFAIK it's just the Xilinx XDMA core connected to a Xilinx 10G MAC. No accessible transmit scheduler, no offloading of any kind, etc. Just about as spartan as you can get, and it's built from completely closed components so you can't really make many modifications to it.

For what we're doing, we can't use any existing commercial NICs or smart NICs because they can't provide the precision we need in terms of controlling transmit timing. We don't care about EBPF, P4, etc. We care about PTP synchronized packet transmission with microsecond precision.

This is pretty spot on. I tried something similar a while back and found that the typing latency was on the order of ~120 ms which made it feel mushy and led to a lot of errors.
The need to rethink graphics to handle refreshes should not be underestimated. A lot of UI patterns (almost all animations and transitions) rely on a period refresh rate. In order to make a compelling experience you need to rework a good bit of the UI.
> If they are being ordered to carry out a first strike, they have no idea of whether or not that first strike is reasonable, or not. And it's not their job to second-guess.

Though it is their job to refuse to carry out the order if it is unlawful (under both US and international law), which a first-strike may well be (as any first-strike is quite probably an act of genocide).

The obligation not to follow unlawful orders (like killing civilians) while also their entire job being firing a weapon meant to kill indiscriminately is… interesting.

I won't disagree that anyone who is likely to consider questions of indiscriminate murder of civilians and other such things prohibited under law will likely be structurally excluded from being put in such a position by the military.
One nice thing is that you can see the displayed image by whatever light you want. Outside, inside, firelight, incandescent, vapor-arc, [built-in] LED... whatever.

I have a feeling that the contrast is also better under dim light, but no evidence, so I might be full of shit. And LED/LCD tech is obviously getting better in this regard.

Still, if there was a good implementation of an E-ink monitor with a refresh rate good enough for text editing, I'd easily drop 10k on it. I spend hours every day writing and reading and my preference for staring at E-ink displays over all other technologies is no contest.
This isn't really how most people should read books. You aren't reading a book to learn arguments like a parrot. The meaning of all the books he mentions has changed over time, and you won't have the same understanding the second time you read it (i.e. years after, re-reading it straight after is pointless...it is robotic).

Also, just generally I think the structure of the course is bad. Reading three books cover-to-cover is basically pointless (Keynes esp. so as it was a textbook, I think he would turn in his grave if he thought people were being subjected to this, both Marx/Smith are very dry in areas too). It would be far better to look at the key ideas across more periods and get students to engage directly with those ideas...which is why similar courses in philosophy, theology, etc. do this.
Silver Falls is a nice family-friendly and easy hike (and pretty touristy as a result), but I personally wouldn't put it at the top of Oregon hikes. My #1 would be Neahkahnie Mountain, probably followed by your choice at Crater Lake and then Angels Rest in the Gorge. Of course, Oregon has a stupid amount of good hiking so it's hard to go wrong.
