That's not idiomatic code.
Seen any articles about 'The Great Resignation' lately?

Yep, and very few mention money as the reason why people are leaving their jobs. It's much more often about a re-evaluation of people's priorities. There's no reason to believe people will find new jobs that give cost of living adjustments.
> Yes, mask may work in some circumstances, but everyone wearing them all the time in social settings?

I found it pretty obvious almost two years ago already that N95s are pretty good at filtering particles (even smaller than rated) and that most people are pretty bad at using them consistently. Further evidence is great, but I wonder if people really are surprised to find this out.

One thing should have been obvious to everyone at all times: You cannot eat while you wear a mask. People take their masks off all the time to have a meal together. What's the point of wearing a mask for the rest of the day then?
I would love to hear something about the chemistry implications as opposed to just the algorithmics. (E.g. to a chemist the local environment of an atom in a molecule is all important because that impacts the NMR, what reactions can affect that atom, etc.)
> Why aren't companies doing this?

I don't know why the company you work for doesn't do it. In the place where I live (Europe), it is fairly common for medium and large companies - my salary is updated every year to reflect inflation. This is independent from pay rises and is happening automatically to all employees. The places where it usually doesn't happen is the smallest companies like startups and mom-and-pops where every penny counts.
I totally agree with you and that is why I have also added to the post the link to the open course MIT site.

I also believe that is quite naive thinking that you can learn math in some depth just watching videos (at least with my capacity). For me it is a way to keep some pace and order when learning and, as you say, to find some bibliography and material that is being used by the professor.
Also, will Monero ever become a supported payment method?
Seeing more and more ‘multiplayer’ text editors here, great! Looking forward to a lighter alternative to Etherpad-lite.

I'm sorry you're in that situation. It may be more possible to get out of it than you think. I felt I was stuck in my previous job (which I stayed at for over six years) and dragged my feet to go job searching because I expected I'd struggle to get through technical interviews, and also was worried my skills had atrophied a lot since I was learning a lot of tech for something not high in demand (telecom-based).

But when I got serious on the job search, finally, I got about 10x more recruiter interest than any previous job search in my life, and the technical interviews I mostly did well on (a few places I didn't). And landed a job that uses very modern technologies and a 60% salary increase.

Maybe it could be the same for you as well. Companies are much more hungry for employees right now than they were two years ago.
Simply existing in a capitalist society is enough to have the cons explained at you.

If not in the almost exclusively investor owned media then in the attendance-mandatory antiunion propaganda meetings you will be forced to attend if managment start to fret.

There's no danger of not hearing the cons.
That indeed is a good link.

If you’re setting yourself up in a consultancy, you don’t usually need start up capital and hence no loans required.

Bank accounts and insurance are a requirement however!
I believe the study mentions many of the issues you just described. Are you saying the article about the study is meaningless or the study itself is meaningless?
Isn't that just pumped hydro? You would need similar masses of water.
It won't happen because those criteria are antithetical to the purpose of a union. Unions are about solidarity as a working class against corporations. It doesn't work unless members see eachother as on the same side regardless of perceived competence
Financial analysts != energy technologists with a scientific background.

You do not need LinkedIn. I closed my account there early last year, and have never regretted it or feel that I miss out on anything. Instead, needless distraction has been removed. I was on LinkedIn for 12 years, and never once got a consulting gig from it; rather, those all came from colleagues, Craigslist, and DICE. I looked for new opportunities this past autumn, and found _plenty_ without LinkedIn.

YMMV, and for me a key factor is that LI is heavily slanted to full-time employment. For consultants, its value proposition isn't so great.

Good luck!
I feel similarly. I love playing around with Julia, and it’s nice for academic one offs, but I wouldn’t choose to use it for a serious deployment at my job. And the interesting part about ML is that industry is very close to academia relative to other fields. So that predisposes a lot of academia to using SKLearn/Pytorch/Jax etc., because that’s what industry is using, and it’s getting the most development.
Instead of doing 10% raises across the board, companies should do raises bottom up and use dollar amounts instead of percentages. 10% of 50k is way less than 10% of 400k, it's not a "fair" raise.
Abstraction is inherently not about deduplication, it is about capturing intent and meaning. About the universality of certain concepts within your code base. Either based on your problem domain or in the context of your application architecture.

Once you abstract only to shorten your code you’ll likely regret it quickly.

"Everyone is a high performer or thinks they are at....", but not everyone can be with in a given cohort. But who really knows? The employer might know based on their internal metrics, but is that info worth sharing accurately to the employee? Wouldn't you want your high-performers to think they just might be just good enough to keep "performing up" and costs down?
Very common
Aren’t KN95s just N95s with the Chinese standards (vs US standards) but should technically work for the same particle sizes?
- Scraping faces to find missing persons: ethical

- Scraping photos to create deep learning VQGAN+CLIP art generator: ethical

.. we can go on and on, but we should all agree scraping is a useful tool that should never be outlawed.
Does it matter if the artist themselves rejects the idea though?

People were discussing having a "no machine learning clause" back when Copilot was being heavily scrutinized. I wouldn't be surprised if some artists allow republishing but not machine learning use. Plenty of artists already have a clause that prohibits any kind of republishing, and Danbooru is known to rehost some of those artists' content anyway until the artist notices and requests that it be taken down, if ever (for a time, they even allowed paid rewards from Patreon and other subscription services to be republished).

The original dataset from Danbooru probably contained some percentage of content that would not have been there if the original artist had noticed in time.
https://www.amazon.com/Schaums-Outline-Elementary-Mathematic...

Schaum's Outlines are like that "Learn X in Y Minutes" site for school subjects. They give the clearest, most bare bones explanation so you can quickly identify gaps. I had the college algebra book for the required math class in technical school. Between that and YouTube, I was able to pass the class.
The thing with teachers unions and doctors unions you have to remember is that they represent the interests of the teachers or the doctors. They don't represent the interests of pupils, patients, or the public. In fact they have to work directly against those groups for the interests of their members.
Here are two use cases why I scrape YouTube.

- There is no external API for getting scheduled streams or when they have gone live AFAIK. This lets me be notified of new stuff to watch.

- The API for getting a channel's members is locked down. I applied for access to it 6 months ago and haven't heard anything about it from YouTube so I just scrape it to give members perks.
that's a different thing than a less-productive worker not being fired
It's not just a temporary failure, it's potentially the entire AZ going down hard. High Availability network boot without local storage is very difficult/expensive.

They can still use local disks to provision the OS over a network but boot from local storage, and prevent writing to disks from the booted OS (hell, they can completely remove the disk drivers from the kernel!). It just doesn't make sense to ditch the drives from a reliability standpoint. They're going to have a big outage one day just because they didn't want to deal with drives.
And they also stepped away from a discussion that has no chance to come to fruition.
Due to dietary restrictions my basket has remained mostly unchanged for years. Every grocery trip is basically vegetables, meat, brown rice, milk, cheese, and cooking oils or spices if needed.
Unions protect people who should have long since been fired, even when they literally cost the company millions.

That (huge) company actually completely moved overseas. The second (also huge) company moved 100% of their manufacturing to Mexico.

In another place that I worked at fresh out of college, they actually covered their signage on trucks because the truckers were being beat up in truck stops and getting their tires slashed. One of the truckers told me that he made top of the industry wages and he was happy with management and didn't see any need to join a union, but that he was worried about getting beat up if he didn't vote to join.
unions are about workers, not investors

Yes, and so do research orgs. My organization does a lot of scraping because we deal with local election data and that's. Uh. Let's just say that if all counties had websites that were like Web 1.0, that would be an improvement over the current situation.
I didn't dv, but that'd be .63%. That's not peanuts I'd say...

No. I got all of my contracting jobs via HN (except the first one, which was a natural transition) and am very grateful for that. All of my clients were / are great, professionally and personally.
I think that opens up a discussion about sensor size not being the biggest factor in image quality and whether it's worth it or not in practical terms to have a large sensor. Personally I have found that my full-frame DSLR gets a lot less use than my phone with a sensor size that is a fraction of the DSLRs! Yes, artsy bokeh shots/low light photos (although this is subjective due to recent developments with smartphones) are easier to take with a larger sensor, but I almost feel like they're going obselete now at least for every-day use.
The particles are floating around in the air. They don’t hit the glass and turn around and go home, they continue to float and a draft or whatever will disperse the particles throughout the room.

Sure, what do I care? I care about people not corporations. There are competitors salivating to scoop up any devs who are out of a job if Google goes under.

>it would be wise to look at why we got rid of them. I'm the UK

It would be wise to question why the military was brought in to get rid of them - both in the UK or the US.
I wouldn't say I'm great at math, I scraped an A-Level in it over twenty years ago, didn't use it much for years, but then I got interested in graphics again and there are some severe gaps in my knowledge.

I remember at the time, I just did not understand matrices, I now use them a hell of a lot and I still suck at them.
Linear algebra is another one.

Most other stuff day to day stuff I can reasonably understand, or at least sit down with pen and paper and work out what I need to do but the above 2 frequently get my head stuck in knots, I often think about maybe doing a course on these 2
Thanks! these are not the only stories I could tell, but just two picked at random.
That looks like a great resource! How often is the data set "updated"?

I'd imagine most people's use cases need data which can change from day to day or week to week but I do think that this is fantastic if I was to have a project which was looking at data across a longer timeframe.
I buy exactly the same things every week and my grocery bill has gone up 25% in the last 12 months.
Got my last two jobs via LinkedIn. I don't engage much with LinkedIn beyond using it as an online resume and a job hunting tool - they basically ruined the groups feature a few years ago AFAIC.
It is pretty common. The goal of the minifier is to reduce the size of the file, so taking the function names, variable names, etc and making them as short as possible works towardd that goal
I guess instead of:

/index.res

/posts/index.res

You’d need:

/index.res

/posts/posts_index.res

Their constitution has been completely rewritten several times, most recently in 1987.
My step-father is in his 50s and is currently doing a masters whilst working full time. His kids are admittedly old enough to mostly look after themselves at this point, but 1 of them still lives at home and he also most of the cooking and cleaning in around the house.
I am a midlevel frontend developer. I had to look for a job one time per year for the last 3 years.

3 years ago I tried everything. I applied to (literally) hundreds of position. More than 100 on LinkedIn, which led to nothing (50% ghosted, 50% automated rejection). Applied to a few from HN (“Who is hiring”), a couple of interviews, no offer. A fez dozens on AngelList, a few interviews, one offer, got hired.

2 years ago I mostly gave up on LinkedIn. Still applied to a couple of dozens there, same result of 50% ghosted 50% automated rejection. Applied to a few dozens on AngelList, a few interviews, no offers. This time, on HN, I applied to all positions that I could be a match (for two “Who is hiring” threads). A few interviews, got hired by one of those.

Last year I ditched LinkedIn completely for applications. I did not apply for a single job there (but kept my profile updated and I could see that my profile was visited by people from the companies I was applying). Applied to all of HN positions of December’s thread, several interviews, two offers. Applied to about 20 positions on AngelList, a few interviews, one offer, which I ended up accepting.

So LinkedIn is a complete waste of my time when applying to jobs there, but I believe keeping a profile there helps a little (although probably a good enough resume file could do the job).

Some caveats, with more experience my application-to-interview-to-offer ratio improved a lot, except on LinkedIn. There a couple of reasons for this I think. Big companies use LinkedIn more. Big companies have more silly (imo) requirements, having a CS degree (I don’t) or the recruiter recognizing where I studied (I went to college in Brazil).

Also, this last time I was back living in Brazil, so I wanted companies that hire globally remote and that’s mostly small companies that don’t use LinkedIn for hiring.

5% does seem excessive. I worked at a unionized tech company, and I paid 0.5% as union due.
A union at google would be sufficient for the unions to operate a single party state. It's not a workers rights issue, it's a national security one, imo.

Actually a few RDMBSes (Oracle, Postgres, MS SQL) have graph extensions. I've never used any of them, but I assume they work around some of the basic unsuitability of traditional tables for storing graphs.
This really only applies to the scrappy startup phase before finding product-market-fit with a minimal viable product. Once you've hit that write tests.

We could say no here shortly after finding product market fit to make a more featured v1, but I wouldn't want to work at a place where a big part of the job is backfilling missing tests.
Grid storage is going to be big business in the future, on the order of size of storage for electrical vehicles. (And these will certainly not be mutually exclusive markets! Vehicle to grid tech will become widespread, as is already seen in the new F150 Lightning truck). Lithium ion will dominate for the foreseeable future, as the industry has scaled to massive sizes and already, and has the advantage of being currently unstoppable in the EV space.

Batteries with a design that can decouple the energy from the power ratings, like this one, will be able to address parts of the market that lithium ion cannot. And if the cost per MWh of additional energy is cheap, and round trip efficiency stays above 50% or so, that sort of battery will have a huge edge in a part of the market that currently has no clear winners.

There are many competitors in the non-lithium ion storage space, but one of the top contenders to watch is Form energy, which has a rust-based battery, and is rumored to have a cost as low as $20/MWh, about a tenth of that of lithium ion.

> union employees who contributed nothing for year

Me and my co-workers create wealth, a portion of which is sent off in dividends, the majority of which is going to heirs who have never worked a day in their life. I am more concerned about that than that the guy working next to me isn't killing himself more to fill that heir's pockets.

Organized labor is made up of the people working and creating wealth. Of course you don't mention the indolence of the idle class expropriators who the people doing the work are organizing to combat.
I bought up COLA with a director and was told 'we were all the in the same boat'

I hate that attitude from higher ups. An employee looking at inflation and wondering if they'll need to heat their home less or much less food is not in the same boat as a higher up manager who might have to buy a new Mercedes every other year instead of every year. It might be the same problem for everyone, but it absolutely doesn't have the same impact.
I just popped open DevTools on an SPA I made using create-react-app with default settings. Sure enough the minified production JavaScript uses shortened variable names. This is default configuration for Webpack, which is pretty widely used throughout (and outside) the React ecosystem.

Interestingly you can still view the unminified source, since create-react-app generates source maps by default.
> Out of curiosity, what does it look like to not-suck at math?

The speed at which you an understand, internalize and can put to use a new concept when it is presented to you.

This is usually combined with the practice of the trade providing you with actual pleasure, which is, of course, a self-reinforcing loop.

Some folks can take a single semester of linear algebra and absorb the majority of the thing, including learning far more than the course required because they truly liked it.

Others can take the first half of their career to finally understand the ideas and apply them properly.
They often do the things you say, but not always. It's up to the members.

Look at the unions for professional athletes or for Hollywood writers for examples where unions are mostly doing very good work on behalf of their members.

In tech almost all workers are heavily invested in their companies.

US unions are like US healthcare, regulatory capture makes them suck. Unions working well in other countries doesn't mean it works well in USA. And neither party wants to improve the state of unions, democrats are on the side of union leadership while republicans are just anti unions in general, none wants to support workers on this.
