> Are there any "math for people who just want to use it" tracks in math pedagogy

It's called Industrial Engineering /s (but only kind of)

It is tame as compared to a pure math or physics B.S. But, you pretty much cover the gamut of every math tool that is useful in the real world. From stats, supply chain, search, calculus to combinatorics and so on. Each concept is squarely grounded in a field where it is used.

I was surprised at how well my mechE (usually the closest undergrad degree to Industrial) degree prepared me for applied math and ML coursework for my CS masters. In comparison, a lot of CS undergrad peers struggled in those courses.
What do you mean like me? I live in the country with probably the highest immigration rate in the world... We've taken refugees from every conflict I can remember. I have friends from Kosovo, Libya, Syria, Afghanistan, Ukraine, Russia, Eritrea, Ethiopia, Serbia, Croatia, etc...

Just discussing legality, not my opinions. My opinion, as someone who's half Ukrainian living in Canada, is that they should come here (we have a historic Ukrainian community here in Alberta for example) or another country they're truly welcome. I know for a fact there's also large, established Ukrainian communities in the Czech Republic and Poland as well. They integrate easily there.

The UK has already suggested they don't want East European migrants (part of the impetus for Brexit) so why force em?
okay okay I'll be more mature here, I checked it out and it doesn't come up that way on my google predictions! tried new sessions on different machines in different locations
> When doing kernel releases, the Linux kernel community almost never declares specific changes as “security fixes”. This is due to the basic problem of the difficulty in determining if a bugfix is a security fix or not at the time of creation. Also, many bugfixes are only determined to be security related after much time has passed, so to keep users from getting a false sense of security by not taking patches, the kernel community strongly recommends always taking all bugfixes that are released.

> Linus summarized the reasoning behind this behavior in an email to the Linux Kernel mailing list in 2008 ...

Since severity can be a moving target, it seems like there is no straightforward solution. With that said, by hiding the known ones, older distros don't have much of a hope in hell of getting all reported CVE fixes back-ported.

Why isn't there a public index mapping known CVE fixes to git commit IDs? This seems totally doable and would make the world a more secure place overall.
You're really misusing words based on common meaning.

And your phrasing can't reconcile why "90% of startups fail".

You're making a values judgment that's talking past this thread.

It's not my only news source given I work in politics/civics, but HN is what I use for understanding the way the conflict is impacting the Internet on a technical level and the discussions of tech politics. For example, the request to ICANN, discussions on whether or not to cut off Russians' ability to use foreign infrastructure, etc.

It's invaluable for helping me follow this one specific area.

Edit: Also, I would like to say that the idea that 'every place on the Internet has to address every major event' is not really great for anybody who works in a related area. Think of political issues taking over hobby subreddits: I'm literally a civics educator, it's not super fun for me to log in to talk about video games and get greeted with 'if you don't agree with VERY REDUCTIVE BASIC 101 POSITION/don't want to see discussion in these spaces, you're terrible.' I put in almost 40 hours a week and do more than you do, random (likely 16-20 year old) Reddit mod. I don't need your lectures, I need to see crazy ways to break video games.

Like no. It's just that it's like being a math teacher and logging in to see people sharing (often wrong) math test answers in your beer group. You need a break for your own mental health.

I'm starting to get really concerned for the overall mental health of the journalist class + political staffers. The ability to step away from the pressure cooker is integral to maintaining your stability.
> The bug is that they are reusing (or, repurposing) an already-allocated-and-used buffer and forgot to reset flags. This is a logic bug, not a memory safety bug.

This statement is incorrect. They are using an arena allocator, and there is no way for it to know if it is reusing one of the elements or using that element for the first time. To do this in Rust you would probably be using the MaybeUninit type: https://doc.rust-lang.org/std/mem/union.MaybeUninit.html

However, you are partly correct. In Rust, when using the MaybeUninit type, it is still possible to partially initialize an object and then return it as if it were fully initialized without hitting a compile error. https://doc.rust-lang.org/std/mem/union.MaybeUninit.html#ini...

If you do the whole struct at once, rather than one field at a time, then the compiler still has your back:

let foo = unsafe {
let mut uninit: MaybeUninit<Foo> = MaybeUninit::uninit();
uninit.write(Foo {
name: "Bob".to_string(),
list: vec![0, 1, 2]
})
}
Are you talking about the Russian guy, that came from a Russian party that was supposed to lead Ukraine in name of Russia?

Doesn't seem like he had Ukrainian interest in his priority list and considering your response ( justified or not), you were already aware of that.
I forgot about that video. It's funny that one thing in that video did come true... from google, and it's great (predictive sentence completion).
People should note that having dreams without figuring out how to get them accomplished is a sure way to have regrets. We are told that we should chase our dreams with the idea that if we wish hard enough they will come true - popular entertainment re-enforces it. I think that's why there are so many people that buy lottery tickets hoping their dreams will come true once they have the instant money of a win. But the reality is that only a few people will win the lottery. It's by design. The lottery is built with the idea that only a tiny percent will ever get the big money. This seems like it's obvious but a large number of people just believe that dreams come true by luck. So keep in mind that most dreams are achievable you just have to work towards them by setting up a life plan.

-Define dream

-Set up a plan to the goal/dream

-execute plan until achieved - but review on a set time table to make sure you are heading in the right direction.

Start, life really is short.
Armored trains were surprisingly effective during WW2 https://en.wikipedia.org/wiki/Armoured_trains_of_Poland#1939...

"During the Polish September Campaign, Polish armored trains took part in roughly 90 clashes with the German units.[5] They played a significant role in several encounters, most notably, no 53 made an important contribution to the Polish victory in the Battle of Mokra, and no 54 was used very successfully in the defense of Silesia.[5] Armored trains were responsible for destroying or damaging several dozens of armored vehicles, including tanks, shot down or damaged three airplanes, and inflicted numerous infantry casualties.[5] Only two trains (no 11 and 55) were destroyed in direct combat by the German land forces, and only no 13 was destroyed by the German air force.[5] Remaining trains were abandoned and destroyed by their own crews when they ran out of munitions and could no longer retreat.[5] The successful role of the armored trains, considered obsolete by both Polish and German strategists, caused the revision of that judgment by both sides"

The most successful one https://en.wikipedia.org/wiki/%C5%9Amia%C5%82y_(armoured_tra... fought on both western German front and later in current Ukraine defending Lviv from both Germans and Soviets attacking simultaneously arm in arm.

If you don't have money you spend a few evenings setting up referrer protection of some fashion and serve goatse to unauthorized clients. Problem self-solves over time. I was on the receiving end of this a few times, back when I was young and had no way of paying for my own legit image hosting.

If you have money you may also have scale and a public image, so this solution is not so palatable. And since you have money and lawsuits are socially acceptable, you go that route.

If sending security to your house with baseball bats were socially acceptable that would be the route utilized.

imho "perfectionism" itself isn't really a thing, it's a noble-sounding name we give to things that we're afraid to confront. Fear of looking foolish, fear of making other choices (and potentially choosing wrong), fear of finishing something (because as soon as you do, you open yourself to criticism / the uncertainty of the ship), etc etc.

Without knowing you personally, the strategy I suggest is to honestly think about what your perfectionism is. What's stopping you from stopping? "I need things to be perfect" is not an answer to this question, it's the smokescreen you throw up to stop yourself from asking harder, scarier questions about what this behavior is. Good luck!
Yeah. My read on the paper was that a fourth dose might be useless. You get the immediate antibody response for a few weeks, and then you're back to same as after three doses, which is memory cells.
I don't think its related really and just happenstance. Its just a sign of market maturity that communities haven't accepted a survivorship or succession path that all organizations have to content with, instead of putting all their confidence on an unsociable do-it-all savant.

> I'm not sure how you prove that ext4 is less likely to become corrupt. But it is easily shown that it's less likely to inform you that there's corruption.

I didn't talk only about corruption of the filesystem itself (I don't know if it's more or less likely with BTRFS, someone says that BTRFS is more likely to become corrupt with power failures, I don't know if it's true), but also from hardware failures. In case of a disk with damaged sectors (I know that we should have 3 backups with one offsite, but you always have that one disk with important data on it that it's a year that you are promising to backup next day till it breaks) I think that a filesystem with a simpler structure will lead to an higher probability of recovering the data, while I think that with BTRFS, or any filesystem that is COW, uses compression, volumes, etc that is more difficult, because files are not stored as plain blocks on the disk, but have a more complex structure that must need to be decoded.

Also BTRFS is kind of a new filesystem, that has two disadvantages, there are not all the tools that were developed over the years for ext4, and also BTRFS driver is continuing evolving. Why I can be pretty confident that if I format an hard disk today with an ext4 filesystem in 20 years I will find a driver for a modern Linux (or whatever OS will replace it in 20 years) to mount it, can we have the same assurance with BTRFS? I don't know.

So for the purpose of making backups and archiving data, I think that I will stick with ext4 for a while. While on my laptop, and systems that I use, I use BTRFS without any problems.

I am currently doing something similar, but I have more experience and money saved, several apps already in progress, and trusted developers that I work with.

Maybe our skillsets won't match, overlap too much, or we won't find a common goal, but you never know.

When did you do your Engineering degree? When I did my BE Degree (2004 to 2008) Linear Algebra was included. We were introduced to the basics of linear Algebra in year 12 of high school (simple matrix manipulation, intro to vectors, dot and cross products that sort of thing). I'm Australian if that makes a difference.

The Math in my 4 year engineering degree was structured something like this:

First Semester Year 1 two math courses: Calculus 1, Linear Algebra

Second Semester Year 1 two math courses: Calculus 2, Sequences and Series (this one was probably least useful all I remember from this 15+ years later is Taylor Series and Binomial Theorem)

First Semester year 2 two math courses: Differential Equations, Statistics for Engineers.

From second semester year 2 onwards there were no more discrete math classes this was where the degree really specialized into various engineering streams, Mech Eng, Chem Eng, Civil etc. Had their own courses. I studied Materials Engineering some courses were shared with other eng students (For example I shared Thermodynamics with Mechanical Engineering students) but others such as Non-ferrous metallurgy were pretty deeply specialized.

A lot of subject used built on earlier math (Fluid Dynamics was backed up by lots of differential equations for example, stuff like Gamma Function would come up in a lot of places. Solid Mechanics had a lot of integrals second moment of area etc.), Linear Algebra I can remember from Fracture mechanics and crack propagation (Stress and Strain tensors etc.)

The author clearly haven't read the top Bitcoin book (the bitcoin standard) as an introduction of what problem Bitcoin solves (inflation).

He changed his whole life by moving away from Turkey to the country with the reserve currency status and then says that ,,everything's fine with the money and banking system''. I challenge him to move back to Turkey and interview some people there.
> I'm a little snarky, but you have a broken idea of what math is.

I do not, which is why I explicitly acknowledged that what I want is not "real math". I don't care about math for math's sake, even a little. Not my thing, never will be.

Basically I want to learn to apply useful results from hundreds-of-years-old "advanced" math the same way I learned math in grade school: memorization, pattern recognition, heuristics, intuition, and drilling, all with a focus on application. Keep the proofs far, far away unless there's some excellent reason I have to know them (and perhaps there's actually no way around that, but I suspect the current situation has more to do with the interests and world-view of people who design math curricula, i.e. mathematicians, than strict need, if you're mainly focused on application). Ideally, almost every single problem set would consist mostly of so-called word problems, drawn from realistic circumstances.
> This is actually saying German imports from France will potentially cause an energy shortage, exacerbated by Germany's exit from nuclear generation

Actually, both countries import and export energy from each other, we're importing from France outside the winter when we have shortfalls with renewables because our grid can't shift enough energy from North to South. The difference is that unlike France we don't go and pat ourselves on our shoulder for being oh so carbon friendly. That French claim to grandeur can only be made because everyone ignores that it depends on Germans and Brits.

> This is the actual measuring stick of success: how much carbon is released for each watt-hour of electricity? France is way below Germany on this.

Yeah, because we have a lot of old coal stinkers that drive up our g/kWh emission average - and because the followup emissions of nuclear plants (from construction and teardown of the plant as well as the operation of the nuclear waste storage and the mining, refining and transport of the fuel) have been underestimated [1]. The old figure used to be ~66 g/kWh whereas the actual upper bound is 180 g/kWh which is even more than natural gas (~117 kWh).

The elephant in the room is followup costs though - nuclear power has a lot of these, from insurance in the disaster case to the teardown and storage of the waste. If these costs that are currently effectively offloaded to the taxpayer would be accounted for, nuclear power would be at 90 ct/kWh, and that's the optimistic case.

> And lastly, it's strange to call nuclear a "dead" energy source when it's still generating more than wind and solar combined.

It's a technological dead end for short-term woes. The most modern EPR reactor design takes a decade to build apiece, and every other design no matter which base technology has been vaporware to date. Even if we were to commence construction for a dozen plants now, they would only become available in the 2030s!

We need solar and wind now, and actually smart grids where big consumers like heating systems and providers like electric cars can be coordinated centrally.

It is available for Android, iOS, Windows, macOS, and Linux. (At one point there was even a version available on Windows Phone 8.)

Perhaps it checks your boxes of good RPN calculator, available on all platforms. I don't know how much an HP-42S feels like a 41C.

In any event, thank you for ralc. I've off and on been searching for a nice web-based RPN calculator.

A few days ago there was another post about Google and Ukraine. I took another look at it and found an update that I hadn't seen until now:

This is an excellent explanation of the process. Like a lot of people, I was pretty surprised at how the certification works when I first learned about it. It's way more about checking that you have a process than it is checking that the process is sound.

I am not a hospice worker, but I have heard more than one old person say #2 and #4 - that they were busy working and did not get to see their kids growing up as much as they wanted, and they wish they had not lost touch with old, good friends. Not sure why she did not hear this from the thousands of older people she worked with in hospice care, I have certainly heard it.

That's perfectly fair, in fact I don't even recommend using Litebulb for senior positions. The problem for senior openings is always going to be sourcing (there's just not that many good engineers to begin with that meet that bar). We've found that there's no discernible difference between the code of strong intermediates and seniors anyways. For seniors, you're looking for qualities like ability to mentor, to give direction, to architect, to produce specs given vague client demands, etc.

I do however think there is a non-negligible boost in signal accuracy for intern and junior candidates for the first 6 months. Predicting long term growth comes down to things like work ethic, willingness to learn/grow, and resourcefulness, but immediate production-readiness is an important attribute for many companies, especially earlier stage.

These virtual interviewing pain points all make sense, and if I'm not mistaken, https://www.dover.com might have solutions to some of these. Full disclaimer, they are a client of ours.
