> In my limited experience, a lot of students seem to have specific weaknesses with the subjects that are traditionally taught in middle school. Manipulating fractions, applying the distributive property consistently, and simply understanding how to dereference a variable by inserting an equivalent number or expression -- I have multiple students messing these up pretty much every week.

Yeah, this is a frustrating one.

I've been catching up my little brother on some math stuff, and I can see him slowly getting better with distributivity, but it's tough.

The frustrating thing is I have a really good sense of what error he's likely to make and why, but I also know that when I try to explain it it's just going to confuse him and he's going to think "your explanation makes sense to me, but my explanation also made sense to me and apparently it was wrong, so how the hell am I supposed to know how to solve this?"

I feel like this is a problem that could be solved with technology, but existing solutions are really terrible at it. I looked at Brilliant, but it does the same "explain complicated mathematical concepts with words that sound logical (and pictures) so the next time the kid tries to understand a complicated thing they'll come up with their own logical-sounding explanation and be completely wrong and get stumped" thing.

EDIT: I think something like an equivalent of Human Resource Machine, except for proof solvers, would be really nice.
Which is why the opponents, backed by a non-partisan alliance of representatives, will bring forward not one but two proposals to the houses. If they get a majority vote, the federal council will have to try to make it into a law.
I guess I only shop with stores that use Kivra.

BankID doesn't store any information, and I have no problem that the stores I'm a member in store my shipping history.

I think you are overstating the scale of the surveillance. I don't think the different entities share data with each other.

Edit: try live in a country like Switzerland once you have gotten use to all interaction being online. It's horrible.

Edit2: actually other stores provide digital receipts without Kivra. You just have to be a member.

Edit3: This has nothing to do with patriotism, there are many things that I don't like about Sweden. But the fact that we have taken digitalisation seriously since the 90s is something I think is great.
You're probably right. It's 'political incorrectness' as a selling-point that irritates me. I don't know if that's weird, probably not worth debating
If you care about privacy, you'll pick flows that all your users to maintain their privacy.

As stated, my project is an internal company project and will be entirely on company-owned hardware, so I don't care about my user's privacy in this case.
I don't see how that project helps solve the underlying problem: denial of service

if the idea kicks off, instead of spamming packets directly at their targets: kiddies will switch to feeding cloud-fail2ban with their target's IP addresses

This seems like a great deal for everyone involved!

I think the real takeaway here is that many entrepreneurs are not interested in running successful business. They'd rather be starting new things! So if you are good at running businesses there's a decent chance you can take over their business in return for letting them keep a lot of the profit. Everyone wins - the creator gets an income stream to support their future work and you get a business that's already working.

So, less reframing and cutesy phrases, perhaps?

Things might have been a lot different if instead of saying LinkedIn was using "dark patterns" to grow, they were being pieces of shit.
I once had an interview where one of the questions asked was whether I was on working on non-consumer facing products.

They apparently had past hires be angry about doing so.
"Learning" has nothing to do with any of this. Deciding which packets are part of the attack is not hard at all.

What's hard is paying for 100s of gigabits of bandwidth, 24x7, so the incoming packet flood doesn't crowd out the good traffic before it gets to your filtering box.

Basically the only solution there is centralization. Cloudflare can afford to buy 1000s of times more bandwidth than any one of its customers needs, because it has (much more than) 1000s of customers.
I think it's just two camps. The vanillajs camp is people mostly working on their own, who can't imagine what all that overhead is for. The other camp is people mostly working at large corporations, who can't imagine any other way to deal with hundreds of engineers checking in code every day.
Definitely why I voted against it. When I first heard about it I was all for it - until I realized that the plan was to let private companies handle it. Complete no go, glad it got rejected.

The direct consequences for Muslims are hardly the problem here – only about 30 women in Switzerland (we know about) even wear a burka/niqab and quite a few of them are Swiss converts. Back when we banned minarets, we had like three (!) of them in the whole country.
But we had ads like these [0] all over the country for months again and if that doesn't give you the most profound chills, I don't know. It's textbook right wing scapegoatism and I'm pretty sure Muslims can feel the very real consequences of that kind of propaganda.

Naming stuff is ok. I understand this. It's done in every field.

But calling the "naming of things" a "design pattern" is pretentious. Nobody calls Monads the "Monad pattern" and categorizes it as a sub field of "design patterns."

It's just like how we abstract the concept of getting into a car and commanding the car under the word "driving." That's fine. What's wrong is if We called it the "driving pattern" and place it an area of study within the automobile field called "design patterns."

Imagine if some expert race driver publishes a driving book called "Design patterns" then with an analogy relates it to architecture. Why not just call the book "Driving techniques" and eschew the useless analogy?

I'll tell you why the GoF did this. Because "Design patterns" sounds more academic, and the catharsis of realizing the analogy between architecture and programming techniques inflates the perception of what these concepts actually are. In the end these are just programming tricks or techniques.

Actually, pointing out similar actions in peers of the accused is a valid method to demonstrate that such actions are not misconduct. Or, if we still insist on calling these actions misconduct, then a double standard has been demonstrated.

That said, GGP post did not point out similar actions. Airbus did not risk passengers' lives. That is the issue here: public safety.

I'm uncertain of the reality of deferable interest free loans, but I agree for the need for checks and balances when it comes to non-profits.

It might be as simple as maintaining a letter-grade of B or above on charitywatch.

I would hope it would be something with more teeth though, like requiring signal to be end-to-end encrypted (for real, not like zoom)

It's not an issue of whether it's technically feasible do it, but whether it's feasible to do it with appropriate safeguards that protect privacy and anonymity online while authenticating in a targetted way to those end points that need it.

The right figure to look at is how many plane crashes there are with other commercial flight planes of the same class due to design defects covered up like Boeig did, which is zero.

I agree. I think it was brought up for thought and discussion, and the first comment was strongly critical. If there are other thoughts on it, hope they get shared too.
This only gives more power to government to harass people whom they don't like and who are poor minorities.

> having a central ID for each citizen at birth, and then a way to prove that you match that ID

This seems a trivial and no-brainer and yet you will be surprised how many Americans will be simply denied this sort of service after birth. Racist law makers would put severe restrictions on people they dont like. If they don't get this ID soon after birth they don't get anything. They will be illegals in their own country.

Entire song and dance around illegal immigration, e-verify and all that crap was needless if there was no concept of SSN.
The court, in making their ruling, could forcibly transfer the NFT, as it would make sense that they would give themselves admin status in the smart contract. So there's no reason the blockchain would need to diverge.

Regarding liens, it seems simple enough to say that if someone does not own an NFT "free and clear", then they cannot transfer it "free and clear". It might even be a different NFT entirely (a "liened NFT," where the original un-liened NFT is held in trust by yet another smart contract, with limited or conditional ownership rights given to the lien holder.)

The reason not to use a database is interoperability. Any smart contract can transfer these NFTs according to infinitely nuanced scenarios, and only during disputes would a court need to get involved and forcibly transfer the NFT according to a judgement.
I'm sure there's a fantastic book published in like 1878 containing these tips and lots more we haven't thought of yet.

I founded and built a company based on a threaded, asynchronous multimedia forum system about 12 years ago. It supported any type of content that was 'V.I.T.A.L' : Video, Images, Text, Audio and Links.

(I sadly had to resign from it, after getting royally screwed over by the 'investor relations guys' who were on the 'pump and dump' of our OTA stock, after we went public via a reverse merger.)

I have been thinking of building something like it again recently, using everything I've learned since - technologically and financially.

Best of luck! :)
Thanks for sharing the economics' reply, I found it very interesting. All the good stuff is in the supplement.

They argue that Peters' model produces extreme risk aversion in lotteries with (near) zero payoffs, and such risk aversion is not backed by empirical work or even by intuition.

"Would a person ever prefer a process [A] that, after
three rounds, diminishes wealth from US$10,000 to 0.5 cents over one [B] that yields a 99.9% chance of US$10,000,000 and otherwise US$0? Ergodic theory predicts [A] [... but] [v]irtually everyone will prefer B"

That is, growth models don't behave well at or near zero.

Personally, I enjoyed reading Peters solution to the St. Petersburg paradox and how the ergodicity framework is applied to economics in such a concise and intuitive manner.

But I am reluctant to think that this ergodicity framework will completely remove the "psychological" aspects of economics. The utility of agents still needs to be accounted for. The ensembles that Peters describes are heterogeneous, and agents can derive different amounts of utility even if wealth or growth rates are equal. Think about insurance.

The difference between colour blindness (equality before the law) and your examples is that your examples are not mutually exclusive. You can save the rainforest and the arctic at the same time. You cannot give the final scholarship place to both the Cambodian and the African American. Whatever you give to one is taken from the other, and it cannot be any other way.

> We're talking identity management here. Any government that can't handle that internally doesn't deserve to exist.

... I mean, as a French citizen who kind of wants my government to keep existing, I also agree with the statement you quote?

Our government's public-facing IT systems have gotten better over the last few years, but my default expectations for any new projects would still be for them to mess it up.

Of course, the problem is I'd also expect the average contractor to mess it up in very similar ways, for similar reasons.

The distinction you're making is more about _fundamental_ research vs. _applied_ research, but it is research nevertheless.

From the first hit I found on Google:

* Fundamental researches mainly aim to answer the questions of why, what or how and they tend to contribute the pool of fundamental knowledge in the research area.

* Opposite to fundamental research is applied research that aims to solve specific problems, thus findings of applied research do have immediate practical implications.

CF still requires an Enterprise contract for proxying arbitrary traffic via Spectrum, likely because of the abuse prevention aspect. Otherwise SSH and minecraft is offered at pay-as-you go rates, but a lot have complained about how expensive it is:

I also voted against it. It's a pity that I couldn't approve the e-ID issued by the government.

Yeah, when it was really cold (<= 0F) were were required to wear facemasks (those neoprene masks with the nose fold, paper-punch holes at the mouth, and velcro in the back[1]) to prevent frostbite on the face, and they definitely helped with breathing as well.

What people don't realize, is that we already have fantastic alternatives to Ethereum for low-energy, world-class decentralized networks with built in NFTs. My favorite is avalanche.

Just a reminder that users of Caddy (v2.3.0 or higher) are not at risk when LE gets hit like this, because it will fallback to having a certificate issued from ZeroSSL. Both issuers would need to be down for the whole last 30 days of the certificate's 90 day lifetime before Caddy would be stuck with expired certificates.

Prior delivery is not generally a major consideration in a govt RFP award.

This is in part because no score is ever released related to prior delivery (ie, no central assessment record), and attempts to include it get tied up in process issues (ie, rights to respond, litigation) or claims it is subjective. It also overlaps with govt agency disfunction around scope and requirements and no govt manager wants a failed project, so everyone just sweeps them under the rug and keeps moving. It is crazy though, you are literally hiring the same HORRIBLE firms over and over.

What is PARAMOUNT is that you be willing spend absolute metric tons of UNPAID time responding to RFP's, have enough money in bank to lose 4 out of 5, be willing to go through 2 year RFP processes, be willing to agree to every item on the requirements lists filled with further buzzwords and "standards". This does NOT attract high performing companies, no competent engineer would even put up with this / sit through this. So you get body shop type consulting firms, using giant java framework and other solutions, and everything is insanely siloed.

The crazy pricing is often justified because the hassle in dealing with these contracts from a contract admin overhead can absolutely DWARF actual deliverables, and nothing has to be logical (and sometimes is not).

My recommendations here would be either:

a) just pay to bring stuff in house so you get cooperation, develop open source apps and prohibit any scope creep outside of absolute minimum needed until project is in operation. EVERY freaking agency hangs 100's of new requirements they never even used before onto these projects - solutions can be undeliverable and unusable as a result, for example 40 questions PER VACINNE SHOT here in California is the height of stupidity to make these idiots feel important.

b) pay for actual use / adoption, and let there be a somewhat free market. A lot of time the users of any govt system have ZERO input. Oddly, if they let agencies find their own solutions on a smaller scale, whatever you lose in "efficiency" by not having the megaproject (hint nothing - mega projects = disaster in govt land) you would see some natural winning solutions start to bubble up. I worked with an agency with a totally fantastic contract management / invoicing system, and I kept on wondering, holy hell, they actually got it right. I started to see other agencies use it in neighboring govts - it was great - people really liked it (super easy use, allowed users to do the google, Microsoft etc login even which is unheard of) and it was fast which is also rare.

But then someone convinced the head tech folks they should stomp on everything with the new and improved people. They actually had to roll back the mega project for another year (after years of dev) because it didn't even cover a fraction of what old systems easily did.
This was one of my favorite toys as a kid.
While I agree with the premise, I don't see how this specific event ties to your argument.

A simple Google search shows that the referendum passed with 57% of the voters support, so that leaves us with a 43% who thinks it's a bad idea for one reason or another. Since around 5% of Switzerland is muslim, one could argue building minarets is not such a scandalous idea for Swiss voters.
Yeah, but...

Ask HN: Career options for digital hardware engineer? Startup? Relocating?
Hi HN,

I am a passionate digital hardware design engineer (keywords: VHDL/Verilog, DSP, custom MCUs, all that good stuff) and I am beginning to doubt my career choice. Reading about JS coders or DevOps earning 100-120k in UK or 200k+ in US (++stocks) while I make my ~80k in Germany (nothing else) is seriously discouraging, so I wanted to ask your opinion on what are my options. Since digital hardware design is such a rare profession, I thought that at HN I would have higher chances getting good advice.
So, my options are:

a) re-qualify as a regular programmer (and maybe move to US/UK). Should be a no-brainer, since I have lots of experience with C, so buffing up some hip and fancy JS stack in about a ~year would be feasible.

b) move to US as a hardware engineer. I have absolutely no idea what the market is there. More importantly, my opinion about the US was shaped (and skewed) for a long time by Reddit as a horrible place with high crime, poverty, highly expensive medical care and sleazy lying politicians. I know that most of it is prejudice, but still this option is kind of scary.

c) startup? Theoretically, we (me and my good friends, a total of 2 design & 3 verif) can squeeze out own savings to finance ourselves + several Cadence/Synpsys simulator licenses for ~year or 1.5. What can we develop that would be sellable? Full-blown SoC is financially impossible, which leaves only options to sell some IP or do custom design/verification contracting work. But that market is really taken by serbian & asian suppliers with highly competitive price points.

Maybe some of you can share some success stories about digital hardware startups or individual careers? Or maybe give some guidance on how to re-qualify quickly? Any advice is highly appreciated.

Thanks, HN.

The (generally accepted) argument is that it's implicit in a number of the amendments that make up the Bill of Rights. It's not explicit however as Robert Bork argued during his SCOTUS confirmation hearings to his detriment. I think Griswold v. Connecticut is still considered the primary ruling on the matter.
