> such as Liberia from 1860 to 1990, a famously free country though surrounded by authoritarian territories.

Liberia wasn't particularly free as most of us here might understand the term. While the freed slaves’ constitution was modeled on the US Constitution, civil and political rights applied only to the freed slaves who came over from North America and their descendants, while Liberia’s indigenous population was neglected at the best of times, oppressed at the worst. (And even among the freed slaves’ descendants, those connected with Monrovia’s Masonic Lodge formed a political elite that others could never hope to enter). To a considerable degree, the political strife of the late 20th-century was due to rage at this skewed system of government.

Ask HN: Which blogging software should I use?
I decided to write more of my thoughts down. Then I thought that others might find my content interesting as well and I should start a blog. But which software or platform is a good choice If I start today?
That's sending a shiver down my spine. You rarely see something that so succinctly summarizes what's wrong with this world and how there's still hope. Trump is the closest this civilization got to an antisocial, bat shit crazy, Bond style super villain since that infamous Austrian fellow from the 30s. I'm asking where is Batman when you need him?
You're a member of the Deer Defense Corps, though, and this time you're much better armed than the hunter. You've also had twenty years of training for your mission. It's just that the hunter is really hard to see. You don't have to care about a hunter running away from you, that's not your job.

Given that there are very few B2s, they're only going to be sent against the most valuable and well protected targets. Those are the most likely to have very alert defensive assets in exactly the right place to go after the B2s.
It is generally accepted that the pandemic will end once just about everybody has caught it, because even those cases where people are thought to have re-caught it, if you assume they really happened, are a small fraction of the population.
Pass is great, but it's a very niche piece of software. I was actually surprised (but grateful) that it existed because so many people have a GUI password manager.

I have the Firefox integration (and I contributed to that integration) and like that much better than other software I tried in this space, not least because I understand all the moving parts so if they break I'm not helpless.

I actually did use the Stanford PwdHash linked above on some systems precisely because password managers were so unsatisfactory. But it's clearly true that if any solution in that class were significantly popular it begins to make sense for bad guys to attack that specifically - assume the gibberish in stolen plaintext passwords is actually output from a "stateless" scheme like this and brute force it. Once you decide to compensate for that (e.g. maybe you're going to have a 12 random character master password entered every time you log in somewhere) password management seems like the less awful option.

I'd like to see low value sites that this sort of thing is clearly most suited for (so like Hacker News, or Stack Overflow, not your bank) offering WebAuthn with no password. Blip, you're in. Very safe, but also very low friction.
Fixed point uses a lot less power though, and many use cases are effectively power limited rather than functional-unit limited, since if you really do fill all functional units on every cycle you'll soon need to throttle back your clock speed...

Perhaps a good example of that is video encoding, which is mostly fixed point, despite it looking like a pretty close fit for floating point maths.
There's a Star Trek TOS episode "Errand of Mercy" where the simple primitive inhabitants of Organia are caught in the middle of a war between the Federation and the Klingons. Kirk is baffled because the Organians refuse his help to defend them against the Klingons. Finally when the Organians have had enough they simply make all the guns disappear, revealing themselves to be a much more advanced species than either of the fighting races.

Lisp reminds me of the Organians. It seems simple and kind of boring until you try something you know is impossible and it just works. It spoils you for other languages.

If you install any browser extension and give it host permission to a URL (or God forbid, all_urls) it can see and steal anything on that page.

This goes for everything from your pop-up blocker, to your password manager, to that silly user script doing <fun effect>. They all watch you browse in a way that circumvents good security hygiene.

It's extremely common for extensions with successful userbases (>10k installs) to get approached by folks asking to integrate a mining SDK for revenue share, or sell the extension outright so they can monetize it themselves.

Consider yourself lucky if all the extension does is steal cpu cycles. It could just as easily be exfiltrating your email bodies or watching all password input fields.

The browser extension model is broken. Expect it to slowly die. Manifest v3 is just the beginning. Soon Google will wonder why they're paying a team of manual reviewers to study every extension on the Web Store when the marketplace monetizes so poorly and doesn't contribute to the moat around Chrome.
New cases in China and South Korea have slowed to a crawl.
WOW! There is still some interest in optimization? I'm shocked! The message long was "Operations Research is dead."

Gee, I got started in OR (operations research) at FedEx, covered a lot from some of the best people in grad school, taught it as a prof in B-school, and applied it to US national security and some commercial problems.

Good to see the interest in some of the flight operations work for Lufthansa -- I was considering (no great progress) some of those problems at FedEx!

One commercial problem was allocating marketing resources for some banks. I was given the formulation, 0-1 integer linear programming with 600,000 variables and 40,000 constraints. I derived some non-linear duality theory, used the IBM OSL (Optimization Subroutine Library), and in 500 iterations found a feasible solution with the objective function guaranteed to be within 0.025% of optimality!

Another commercial problem was some more marketing optimization. It was also 0-1 integer linear programming, but surprisingly it was just a problem in least cost network flows. That is also linear programming, but there the simplex algorithm takes on a special form where a basis is a spanning tree of arcs in the network. A simplex pivot is to add an arc to the tree, thus, yielding a circuit, and running flow around the circuit in the direction that saves money and removing from the circuit, thus, making a tree again, one of the first arcs where the flow goes to zero. There is a cute variation of the algorithm due to W. Cunningham (one of my profs) based on his strongly feasible basis, that avoids cycling.

A super nice point about the simplex problem on least cost network flows is if all the arc capacities are whole numbers and if start with an integer basic feasible solution, then the simplex algorithm will automatically maintain an integer basic feasible solution and terminate with an integer solution. It is good to suspect that a lot of integer linear programming problems are actually just such network flow problems or nearly so.

Once I used that stuff to say, for NASA, how to assign signals to satellite channels to minimize some signal interference -- it was an example of the bottleneck assignment problem which should be solvable very quickly by some post optimality tweaking with the network simplex algorithm.

I enjoyed using the IBM OSL, but IBM withdrew it from marketing in about 2003, maybe in favor of marketing C-PLEX. But it appears that at about 2004 IBM donated the source of the OSL (with lots of pieces, network flow, stochastic programming, etc.) to Riverware which might distribute the open source.

I got started with the OSL when I was in an AI group at IBM's Watson lab where the OSL was written. The Watson lab long had some high expertise in optimization -- Gomory (cutting planes, Gilmore-Gomory column generation, etc.) was head of the lab; there was Phil Wolfe (the Wolfe dual, etc.), Ellis Johnson (group theory and integer programming), etc.

So, in particular, if still want to do some OR and optimization, get some quite well written software, and save some money, then might look into getting all the IBM OSL code open source.
There's a recent work that does a great job explaining why humans have a difficult time reasoning.

Ask HN: What are some “domains” that I can learn?
I got my first programming job in Aug 2018. For about 6-7 months I was doing "only" web application development. Then I got an opportunity to web scraping, for a project. I had to learn most of (requests/selenium + bs4) by myself and complete the project. I think I did a good job (after that I got a lot more web scraping projects, in addition to web application development). Then very recently I got a project on word automation. I was able to do this with docxtpl.

I don't know if "domain" is the correct word for it. What I mean is the variety of things I can accomplish with code,

Eg.

Web application development, Web Scraping, Word / Excel automation etc..

Just curious what other "domains" are out there? I didn't even know word automation was thing until very recently.
That's... not reassuring. Though I would still argue that that is more of an implementation issue, not a deal-breaker for the general idea. And there are many KDF variants that (claim to) offer protection against brute force, so that's not necessarily an issue either (but I do agree it sounds risky).
ssh myhost rm -r /var/cache/... for example works quite well. It's not like the server becomes a piece of useless metal once you run out of space.
South Korea really took off after General Park Chung-hee seized power, he built the economy and modernized the country. One of the great success stories is the praziquantel story. Korea had a schistosomiasis problem; they developed a process to synthesize praziquantel cheaply (the original Bayer process was more complicated) as part of the eradication campaign. That was in the late 60s. The Park dictatorship was overthrown only in 1979.

The system I made "sinkless" https://github.com/kybernetikos/sinkless does the same thing. Its a pretty obvious solution to the problem of needing to able to change passwords, and it also solves situations where sites have crazy extra restrictions that can't be reduced to just the alphabet. My system also shows you emojis so you know when you've got your password and site settings right.

I've only written a little bit of it, but it brings me anxiety.

Any language without static types brings me a certain degree of anxiety, thinking at all times about all the ways a given piece of code might be misused and go terribly wrong.

But in Lisp you add another layer: that anything looking like a function call could actually be a macro, further blowing open the door of possibilities for what an unfamiliar piece of code might do.

Of course, parsing Lisp is an exercise in tranquility ;)

It's all about the programmer's personality, I think. Graydon Hoare expressed my feelings: "Basically I've an anxious, pessimist personality; most systems I try to build are a reflection of how terrifying software-as-it-is-made feels to me. I'm seeking peace and security amid a nightmare of chaos."

Martijn Wismeijer: I Used My Implants as Bitcoin Saving Wallets
I’d genuinely like to hear about it if I’m off base, but I took one look at the 2nd tab named something like “When to Close The Office” and it appears to contain dozens and dozens of assumptions. I can’t imagine that this calculation is meaningful in any way. The errors don’t average out here; the curve we’re modeling is exponential, tiny errors in assumptions can lead to roughly 100% error in the output. Isn’t there a word for when a lot of math and complexity and specific numbers with names imbue an article with some extra sense of being true or having authority?

The virus is blooming right now. If a business intends to close or start a work-from-home phase, then it should be happening right now, there’s no calculation to make and no risk model that’s going to tell you to wait another week or two.

There are legitimate reasons some businesses shouldn’t close, but those reasons don’t depend on how many people live nearby, how many are currently infected, etc..
Stunning Insights into the Corona-Panic by Dr. Wolfgang Wodarg
I'm betting on the former. As dangerous as it is to basically blanket call the media liars as Trump has done, there are just enough cases of it being correct to keep you scratching your head. Journalism of today is little more than Gawker-esque trash. I feel sorry for the remaining good journalists, having their industry muddied so much.
In my experience these voice assistants are wildly popular among older and less technically literate people. I have an aunt who has around a dozen alexa-enabled speakers, tvs, and tablets around the house and constantly talks to them—weather, news, turning on the radio and music, ordering things on amazon. She doesn’t appear to be bothered by having to change her behavior to suit the assistant, including occasionally ordering the wrong item on amazon (!) and simply saying “play (genre here)” rather than album oriented listening she normally does, which disturbed me a little bit. Other older people in my life have similar behavior, and on a related point I’ve gotten at least one assistant enabled device as a gift for each birthday and christmas for the last several years (I give them away, I already have too many damn electronics).
> I'm reading your comment from a 170-year-old wooden house.

That's great, but that wooden house you live in is vastly better in terms of quality of wood than what is common today in USA construction. If OSB had existed 170 years ago, I assure you would have long ago turned to dust by today. You probably have magnificent wood beams and single-piece shipboards spanning all studs and joists.

It all comes down to material-quality, maintenance, design, expectations and weather. Sadly, all of those factors take a back seat to cost and speed where modern housing developers are concerned. Modern building techniques make it easy to fool unsavvy consumers into an illusion of durability and quality.

So yeah, it does copy its "runtime". It cannot work purely by running commands over SSH. It needs to copy "its agent" to target, and worse, it does this every time you run it.
Then I don't understand how you "combine the master key and keyfile data to create your key." How do you change the master password without changing the generated passwords?

Check out David Joyner’s work at Georgia Tech:

One of the keys for me is how I get feedback. Multiple choice quizzes can be well-designed. Most are not. But they scale well.

Personally I like very challenging assignments, but with very lenient grading and partial credit, with lots of detailed feedback from the grader.

If you’re teaching a college course, maybe you have enough TAs to make that happen. You’ll see some of Dr. Joyner’s work is on scaling grading systems and feedback.

Disclaimer: I don't know if this article is correct or not. I have no stake in it being correct or not.

But, as the previous posters touched upon, there are some interesting philosophical issues at play here.

First, we have the old correlation vs. causation issue:
https://en.wikipedia.org/wiki/Correlation_does_not_imply_cau...

Then even if there is causation, we need to ask which came first, the parasite prevalence, or the authoritarian government.

Then even if we know the answer to that, we then need to ask if a circular relationship is present, in other words A causes some of B, which in turn causes more of A, which in turn causes more of B.

Basically, if a virtuous or vicious cycle is present (virtuous if more of A and B are desired; vicious if less of A and B are desired; in this case vicious, since presumably less of A and of B are desired...)

It's sort of like you could ask if "breakdowns in society" are responsibile for authoritarian governments -- or if authoritarian governments are responsible for breakdowns in society...

Or, if a little bit of one caused a little bit of the other, which in turn caused more of the first, which in turn caused more of the second, and the cycle became a vicious cycle...

So, the roots of what could be a fascinating philophical discussion in that.

Its sort of like in Star Wars -- we could ask if the breakdown of society caused the early elements of the Empire, which in turn caused the Rebellion, which in turn caused the furher breakdown of society, which caused the further strengthening of the Empire, which in turn caused the further strengthening of the Rebellion (by opposition)...

Vader may have been a key player on one side... but he did not start all of those cycles going...

So while it grieves me, I'll make the joke that Jeff would make were he still with us: "I was just trying to figure out how to avoid the corona virus."

He was brilliant, quirky, and fun to be around. I can't even begin to describe my grief right now.

It was not even remotely clear what they were referring to. There are many different types of lasers.

Considering that the US, Russia, India, and China haven't even signed the Convention on Cluster Munitions there's clearly no political appetite for such bans among countries with large militaries. And such a ban would be unenforceable anyway because small drones are dual use technologies which don't require specialized manufacturing.
