I've known any number of Baltimore schoolteachers. Hell, I used to drink for free thanks to some of them, on account of going to the same bar some days after work and being pretty good at Jeopardy. One I was acquainted with for something like a decade. They're no less likely to be good, dedicated people than those in any other profession - if anything, given the conditions they have to work with, probably somewhat more so.

I'd find it difficult to say what exactly is the problem with Baltimore schools generally, especially in the face of a lot of people who've seen The Wire, know nothing else about my town, and yet somehow feel themselves qualified to dissect it anyway - that's not a shot at HN particularly, that's just what happens when Baltimore comes up for discussion anywhere that isn't Baltimore. But I can tell you what, and who, the problem isn't - I can, and I just did.
What is generally audited is the source code. You can then verify is that the audited source code matches the deployed source code. That ability is lost to some degree (or not as transparent) if you use upgradable proxy contracts (which Meerkat did). Given the young age I don't see any indication that anyone audited the proxy contracts and their usage.

As explained in the blog post of the top comment here (https://obelisk.medium.com/meerkat-finance-and-the-0-that-wa...), this was clearly an exit scam by the Meerkat developers, which is exactly why users shouldn't put any significant amount of money into contracts that haven't been audited by a reputable external auditor.
My alternative is to do a strlen for each string, then use memcpy memset memchr instead.

> I thought they're a safer strcpy/strcat

Let's look at the documentation for strncpy, from the C Standard:

"The strncpy function copies not more than n characters (characters that follow a null character are not copied) from the array pointed to by s2 to the array pointed to by s1."

There's a subtle gotcha there. It may not result in a 0 terminated string!

"If the array pointed to by s2 is a string that is shorter than n characters, null characters are appended to the copy in the array pointed to by s1, until n characters in all have been written."

A performance problem if you're using a large buffer.

Yeah, always prefer snprintf.

The time functions? I'm just very careful using them.
Extra money is rarely used to improve the schools at issue rather than testing and administration overhead. What I found interesting was:

The district’s five-year graduation rate increased by .02 percentage points, to 75 percentage points overall. Since 2010, the four-year graduation rate has increased by 8.8 percentage points overall.

All I want from office software is a clone of Google Docs that would be open source, self hosted, allow concurrent file editing and would use OpenDocument file standard for storing files.

Thanks for the warm words. It’s funny, but we did a poll yesterday about the most desired work abroad destination among 589 developers (exclude my vote - it was Japan). You can find the results - https://www.dropbox.com/s/ga2y72eqwcd9bp6/Relocate.me%20Marc...
That isn't ethanol. That is the cheaper grade of gas they use with ethanol rotting faster. (Ethanol is high octane, you cannot use the same molecules in non-ethanol gas as you can in ethanol) So yes, ethanol free gas lasts longer, but it isn't because it is ethanol free, it is because the gas is better quality.

Aftermarket carbs are cheap because carbs are cheap. You can buy a lawn mower at WalMart for $100, and everyone has to make a profit. That means the engine can't cost more than $20, and the carb must be less than that. The Chinese make a nice profit selling new carbs for $10, even though most carbs still go to the engine manufactures who pay a lot less in quantity.

Ethanol has been common enough in gas since the 90s.In the early years there were problems with it attacking rubber. That rubber hasn't been used in fuel systems for years though.
It is a bit of understated wit of a backhanded compliment given its value is so low everybody can afford it. A massive surge in value is going to over five cents per coin. Of course ironically that makes it a better actual currency instead of a speculation vehicle in spite of being easily mineable by design.

I have, and it turns out that the same people who think banning books is fine also run the library. Oh the irony!
BYOC for shopping online would be nice. Exchange formats for product aggregators sort of solve one part of the equation. But ordering is still an unsolved issue.

It shouldn't be that hard to do. You may need maybe 5 endpoints. Get all product data for the whole stock, get individual product images, get order requirements (can include terms and conditions, desired information for the order, payment options, human contact info, etc.), post an order, get order status.

On this API you can easily create a fully featured 3rd party online shopping clients. Some shopping experiences these days are atrocious.

Some hugely popular platforms have product lists hidden like 4 screens bellow the fold, separated by tons of crap, that just gets in the way. Category selection is placed such, so that categories slide away, when you get to the product list after selecting one of the categories, and if you want to switch category, you just have to scroll all the way up again. No options for selecting alternative views, like in a file manager (large icons with a ton of detail, list view, etc.)

Each new eshop you have to learn how to navigate it, and collecting information about the ToC and payment/delivery methods is a hassle.

Could be so much better if there was some simple web protocol for this, and it could be exposed in addition to existing website, too.

In the simplest implementation, everything but the POST could just be some static json files uploaded to the http server. And POST /order could just be sending an e-mail to someone.
In Solid the primary copy of your data lives in a neutral server and multiple apps can access it. In theory, since Solid isn't really deployed and major apps will never be willing to adopt it.

With data portability you can export data from one app and import it into another but there's no ongoing sync.
I've been working on a tool that lets you see connections between words in your own language and one you're learning. It is based on following etymology trees up and back down. It has helped me a lot and I enjoy browsing around in it.

For example you can see the connection between Spanish 'mano' ("hand") and English 'manufacture', 'manipulate', etc.

Now, what would be interesting is to build a model that accounts for this "knowledge" and see if it can beat the out-of-the-box classifier :-)
I'd assume it can, and the question is: how far can a bit of manual modeling bring us?
I don't think anyone wants ports. I use linux as my home machine now and the desktop application delivery on linux is pretty fractured (flatpak or snaps or debs..). You kinda wish in the small desktop linux market there would be one distribution method to rule them all.

we can't even get MS office or Adobe to port to linux. Open Source coders have done well to get us somewhat working alternatives. (LibreOffice, Krita and Blender come to mind)

I've had good luck with Proton. It makes me not have to use a second machine for games.

The Privacy and Electronic Communications Regulations (PECR)[1] do not supersede GDPR as such, they sit alongside it.

Section 22 is the relevant section they are hoping to rely on, specifically section 22(3) which allows them to:

----------

(3) A person may send or instigate the sending of electronic mail for the purposes of direct marketing where—

(a) that person has obtained the contact details of the recipient of that electronic mail in the course of the sale or negotiations for the sale of a product or service to that recipient;

(b) the direct marketing is in respect of that person’s similar products and services only; and

(c) the recipient has been given a simple means of refusing (free of charge except for the costs of the transmission of the refusal) the use of his contact details for the purposes of such direct marketing, at the time that the details were initially collected, and, where he did not initially refuse the use of the details, at the time of each subsequent communication.

----------

So in this case, they are obliged to let you withdraw your consent every time they email you. It is not a blank cheque for them to keep emailing you simply because you've purchased something; it is consent-based and therefore uses the same consent processes as the GDPR.

At age 20 I decided to no longer add sugar or salt to foods and to avoid consuming saturated fats. This was based on news reports stating the overuse of these items in processed foods.
I consider giving up sugar to be one of the best decisions I ever made and recommend it to you.
Dang, if you think my comment is out of place here, that's fine, but don't mischaracterize what I wrote. Nothing I said was nationalistic or ideological; it's objectively true and reported upon by mainstream media around the world. In the context of my comment, I don't have a "problem" with China. I'm pointing out that China's human rights violations, which are recognized by the international community, are very similar to a certain historical regime cited by the person I was replying to. If this is off limits, then fine, but this sort of overreaction on your part only makes this community less interesting.

By the way, what do you define as "flamebait"? Nothing I said was "flaming" the other person. There wasn't even a flamewar. The closet to that was my comment getting downvoted, which I don't even care about. I'm not going to argue with you, but anyone reading this should at least know how you interpret it.

Maybe it'd be helpful if you were more specific: Should we not comment on a country's human rights violations? No argument from me either way.

Well, actually, a nice source of a large number of neutrons is a HUGE proliferation thread: weaponizable Pu-239 is produced out of easily-available U-238 by neutron capture. Only generation 2 (or 3) fusion, when we move past deuterium, will be proliferation-safe.

Well, as someone deeply involved in education, these statements combined together highlight exactly the problem with America's educational system. Like many American institutions, it is extremely diverse in its methods and primarily focused on providing services to the wealthy. The parent comment here is correct in highlighting a problem that exists at the highest levels in our school system and the topic article is highlighting a problem that exists at the lowest levels. They are very different problems.

However, they have the same root cause. What would actually solve this is a systemic shift in America's education system to a more centralized approach that promotes well researched methodologies and systems to be used across the country. We have phenomenal teachers and phenomenal schools that operate at extremely high efficiency. The problem is that this quality is extremely poorly distributed. This would be very unpopular with the wealthier members of society though, as it would make access to academic silo schools much less of a given for their children. And access to education, and the societal benefits that this access brings, is one of the primary motivators for wealthier Americans. You don't have to look farther than Hacker News. How often do you see titles here like "MIT students launch the Facebook of toilet paper", where MIT student is seen as a meaningful signal. Your child doesn't get the opportunity to be the beneficiary of that headline without first being purchased a top rate education at America's best high schools.

I sincerely doubt that much financial reward will come for any random individual doing this to any randomly selected website in that sample that does not meet the GDPR requirements.

On one hand, you've technically got the right idea that I ought to put some skin in the game. On the other, it's a reasoning meant to shut down criticism on the same level as the infamous "yet you participate in society, curious!" comic
It takes 3 hours to recharge the provided battery on the provided charger. That means a battery could be used, at most, twice in a day therefore still requiring add-on batteries for commercial applications (3x~ per tool, per day).

As to the "rake and broom," point: there's an innate time value to consider for commercial applications. If each job takes longer, you'll do fewer jobs, and could lose money overall.

I'm not really clear on what point you were trying to make? That add-ons aren't overpriced? That commercial lawn care companies should wait 3 hrs between jobs? That manual raking and gas/electric blowers offer the same productivity?
The "only X years away" jokes are predictable, but we'll know soon enough if they can do 20 Tesla - and if they can, then the time tables should be reset.
Your top level post reads as if people who use 'dark patterns' as a term have an agenda, and that agenda is fraud and psychological manipulation.
> This is only looking at currently known reserves, a number which has doubled in only a few years.

False. It is estimating at the total amount of accessible lithium, not just the known reserves.

> For grid storage, weight and specific energy are not important, and sodium chemistries will be ideal. There are also entire classes of flow chemistries that are in their infancy.

Feel free to cite this as an option once sodium batteries actually become available at scale. Until then this amounts to, "hope some future solution solves storage."

> But what is mature and cost effective is lithium ion storage. The only place where we have open data about the feelings of investors, the PJM and ERCOT interconnection queues, storage is being deployed in GW comparable to new natural gas GW.

This is not even remotely true. We don't even have 1 GWh of battery storage [1]. Sure, we're not deploying "new" natural gas because energy demand is decreasing and we already have existing natural gas plants. But the point is that

> And it is falling in cost exponentially. Other battery tech is following and dropping in cost too, but lithium ion is benefitting from having existing markets that can fund massive learning.

Cost is a function of supply and demand. If you actually try to use lithium ion batteries for grid storage, this will create massive demand and thus increase cost. Again, there is insufficient accessible lithium to provide even half an hour of energy storage.

Hey, I also enjoyed the article... and would definitely be interested in reading more about macros.

But unrelated to that, I wanted to comment on this observation:

> In my current project, it takes almost 30 seconds to boot up a development REPL. Half a minute!

I work mostly with JVM languages and the JVM startup nowadays is actually very fast for a VM, under 100ms for your code in main to be running from a cold start. 30 seconds to boot is completely unheard of in my experience. If whatever you're using is open source, I wouldn't mind having a look to figure out what the problem may be.
To be fair, the writer is the CEO of Replit, a hot up-and-coming startup (cliché description, I know, but it's true). So it's understandable that the subject is on his mind, no?
That's why the solution is federation. Data portability is a kludge designed to draw attention away from federation.
When you say it’s impossible to “forbid”, you probably mean “prevent” as it’s most definitely possible to forbid it. Either way, the situation is the same with any crime. Obviously that is not a reason to legalize anything in particular.
I don't quite follow - what's your hypothesis here?
Well my first computer was a secondhand C64 with lots of accessory's, i mean really a lot...a full blown c64 two disk-drives fast-load cartridge 100's of games joysticks everything!! My dad then say'd he needs a real computer an got a macintosh Lc2, and because he was old-school (one computer and one tv per household) i had to trash the c64, one would say an Lc2 is cool...yeah it was, but nearly zero games, all my friends with amigas and dos machines had more fun, i had myst, crystal quest and shufflepuck...and hypercard, photoshop and filemaker...oh and quark express...cool :(

EDIT: I forgot that i had IndianaJones3 too..what a cool game, probably even harder then myst.
This is not how totalitarian regimes are created at all. Commissars in the USSR having the power to ban books meant repercussions from the state for reading or distributing those books, and was a clear signal that similar works would meet a similar fate.

The publisher deciding to no longer sell some part of their work is entirely different. It makes no difference to your ability to enjoy a copy you own or to sell it to someone else. Nor does it affect your ability to create a similar illustrated children's book including whatever stereotypes you desire. No one is 'banning' you from doing this, although it might diminish their opinion of you.
At what point does appreciating content produced by the mental ill become exploitation of them? Gene Ray was clearly mentally ill, but few had any qualms about enjoying the WTF quality of the Time Cube website.

Some of the classic twentieth-century art by outsider artists like Adolf Wölfli was in large part the consequence of their illness, and yet it is appreciated nevertheless, so couldn’t the same persist today for the mentally ill’s analogous creations on the internet?

How does a school with such a low graduation rate prove that they give out high school diplomas to nearly anyone?
It's a pretty good project tracker I think. It's prettier than Jira, for sure, and feels faster for large projects with a lot of tickets.

It feels like it might not be well suited for a large team, but we're under 20 right now, so that's more of an intuitive feeling than a specific criticism.
The predicted 'answer' for the vast majority of people is going to be, basically, left or right (politically speaking), for maybe 80 or even 90% and more people, a 50/50 choice. How far does the 72% drop for correctly predicting the smaller political factions, I wonder?
Not exactly. "Cursed" in modern slang is more like something weird and unsettling in a way that's probably funny and may or may not actually be bad.
"The accuracy is expressed as AUC, or a fraction of correct guesses when distinguishing between all possible pairs of faces—one conservative and one liberal." - so no way to guess better than 50%.

Or the server could hide the data from the client that the client shouldn't be able to act on until just before that data would be seen by the client. (obviously with a slight tolerance for sending a bit extra that clients might need if lag rubber-banding predicts it might be revealed)
American schools are not a monolith. There are some of the world's best schools and (first) world's worse schools. If you could afford a fancy school in the UK, you were likely in a nice neighborhood in the US with enough property tax base for that neighborhood to afford a good public school. The US's problem is that school funding is local and most neighborhoods don't have that property tax base to afford a good school. There is very little top down control and parental involvement in poor neighborhoods with poorly funded schools.
So... we should select politicians from the poor, then?
I dunno... The Mandalorian has achieved everything that the prequels and episodes 7-9 were unable to; it did exactly the things folks said were impossible.

While I've been a fan of Discovery for the most part, and it occasionally shows glimpses of promise, it's largely not "Star Trek." The story telling is simply just not rooted same soul that Trek has been built upon. I'm okay with change, but not so much with creating flashy spectacles at the expense of meaningful story telling.
Agreed...I have tried this and it has huge benefits.
I think if I understand correctly, there'll be a fluid (FLiBe) between the plasma and the magnet coils that absorbs most of the neutrons. The FLiBe heats up and is used to boil water to power a steam turbine.

SPARC isn't particularly designed for durability, but for the ARC reactor which is meant to be the commercially-useful iteration they're looking at having solder joints on the superconducting magnet film so the whole top of the reactor can be removed so they can pull out the inner lining in one piece and replace it. (Apparently they figured out that regular non-conducting solder joints don't actually introduce very much resistance.) I don't think there's any plan to replace the ribbon.
