Not sure why this is flagged. In any case, I wouldn’t try to over optimize for anything right now. If you find those various things interesting, then it means that there isn’t one of them that is the answer that you’re missing out on.

I would just look into various jobs in the industries you’re interested in. Many times the academic subject doesn’t line up with what you’ll actually do as a job.

Also realize that your interests and personality will change over time, so the most important thing is to just “head in the right direction” and not have a master plan for the next forty years of your life.

It's an idiom for telling the compiler “don't give a warning on this argument not being used, I know about it”. Not all compilers will heed it. Other choices include e.g. __attribute__((unused)) (GNU), [[maybe_unused]] (C++17/C23) or just not giving it a name (nonstandard, but very commonly supported).
It is amazing when you visit a city that has banned billboards especially when coming from one that does not.

It's the same (opposite) feeling you get when watching an ad free streaming service and the switch to live TV or Prime. Which is just like switching to a browser with out uBO.

Ask HN: University open courses for software design?
Hi everyone, currently I am trying to learn software design & engineering by these mit opencourse courses

https://openlearninglibrary.mit.edu/courses/course-v1:MITx+6.005.1x+3T2016/about

https://openlearninglibrary.mit.edu/courses/course-v1:MITx+6.005.2x+1T2017/about

I think I learn much better by these
type of university courses and was wondering are there any other universities open courses on subject of software design or construction with actual projects, assignments, pdfs for learning material that other folks have used.

I think these kind of courses can help a lot of students with software design.

Open to any programming language and framework:).
Ants and bees are not showing selflessness, they are showing strict hierarchy and chain of command.

Entirely different concept. Not to mention that ants are very, very far from dogs, dolphins and humans. There is no reason to think that a dolphin would have to share their behavior, nor that a human wouldn't share their behavior - do people really choose to be selfless when they dedicate their life to a company, or are they just mindlessly following the march like the ants? There will be the occasional ant that doesn't do as told, leaving the question of where there are more humans or ants breaking showing independence and breaking out of rank.

For reference, there exist many types of ants that have abandoned the normal ways of ant colonies.

> Isn't it very typical for an ISP to run their line onto your premises and put the demarcation device on your premises with your power supply etc? Usually there isn't a "their side" where it still works.

There is, in my case. Their point of presence is about 800 meters away, and they have a simple switch that aggregates connections. Their optical terminal on my terminal (a switch-sized 1-U rack-mounted box with ANNOYING fans) does all the traffic shaping, authentication, etc.

> It's possible that the termination equipment could be a bare SFP and not a big box, but the ISP wants to be able to monitor the status of your connection up to the termination equipment, because that is their responsibility to keep online, and they can't do that if it's just an off-the-shelf SFP. They probably wouldn't agree to do it and still have any SLA.

Sure, and having equipment on my premises makes it much easier to debug the issue. But they actually monitor the BGP session state, not the optical path.

I had to live off of savings for an extended period of time, after they locked out a significant portion of small businesses from participating in the economy in 2020. The FTB, California's version of the IRS, noticed the unusual activity activity on my account, of me still paying my mortgage, despite not getting any income, and were nice enough to send me a bill asking for tens of thousands of dollars, because it's really difficult to live off of savings, so surely I owe them taxes for something.

Looks like he made his own service manual for this piece of gear and it has the manufacturer's logo on it without their consent.

Which he prepared for the client in decent presentation quality.

One of the most admirable things to do, above and beyond most repair professionals, looks like Mark really is a cut above and it shows.

The top instrument companies have always recognized the advantage of partnering with the rare individual who can service their complex and unique products, and have been the most willing to provide schematics and discounted parts in order to make as many into authorized service centers as possible. To enable field calibration and service, or bench work without having to send their own people or ship the unit back to the main repair depot.

The lesser outfits, not so much.

If you've got money-making instruments to sell, you really don't want to work against someone who has the talent to fix defects without even having any factory documentation. That's hard to come by, they could be your best ally. Imagine what could happen with full factory support.

And Mark prepared his own documentation! How much more respectable can you get?

Posting it on Youtube is the only real mistake, unfortunate but true.

Obviously, Youtube is not a respectable enough place, oh well, who knew?

From the commentary it does look like the circuits are not more innovative than the "generic" guidelines published by the component manufacturers to encourage engineers to adopt their semiconductors for various intended purposes.

When these analog devices were first emerging, some of these data sheets were widely published back when some of the example circuits were still under patent. There was every expectation that if you copied one of them, you would have to license it before you could legitimately include it with your own product. For these preamp components, patents have all expired now so that's not a consideration any more. However it's possible that somebody 30 or 40 years ago might have drawn up a PCB of a completely generic circuit that exactly conforms to an example public-domain schematic, no longer under patent by decades, but that pattern on the PCB could easily still be under copyright for decades to come.

You create your own original artwork, you own it, even if the circuit is exactly the same.

Thus I would say the patterns on the PCBs are only legitimate to reproduce in much less than their entirety, like passages from a book. That could be a pitfall, but I don't think more than a few relevant excerpts were casually shown in the video.

That is what it is afaict, but NVIDIA says this in their 2019 post "Machine Learning Acceleration in Vulkan with Cooperative Matrices"[0]:

> Additionally, if the GPU includes dedicated hardware for high-speed matrix operations, such as the Tensor Cores on Turing GPUs, then the Cooperative Matrix extension can tap into the power of this acceleration with no application changes.

The benchmark graph doesn't look too great, though - around half the "theoretical peak tensor core performance".

I understand the second paragraph, but:

> Having a right and receiving justice are two different things.

That doesn't yet make sense to me. What good is a right if it stays theoretical, without an ability to execute that right in practice?

Or, in other words, if a person has a right but there are no ways to execute that right, how is this situation practically different from that person not having a right at all?
"The rules in this book include:

As simple as possible, but no simpler

Let your code tell its own story

Localize complexity

Generalization takes three examples

Work backward from your result, not forward from your code

The first lesson of optimization is don't optimize

A good name is the best documentation

Bugs are contagious

Eliminate failure cases

Code that isn't running doesn't work

Sometimes you just need to hammer the nails

"

Sounds quite solid - as guidelines. My only rule for programming is, that the result is correct and usable.
Do any of us really care which of these mega-bureaucracies is to blame for each particular hurdle to receiving healthcare?

From the patient’s perspective, they are all conspiring to gouge us, deny us care, and perpetuate their gold-plated monopolies.

The constant factor is that the patient always loses.

It’d be nice if we could have a political system where politicians represented their constituents, rather than their financial backers. But I fear that the culture war has made that very unlikely. It’ll get worse before it gets better.

What often is fully ignored in such articles is the false positive rate.

Like e.g. where I live they tested some state of the art facial recognition system on a widely used train station and applauded themself how grate it was given that the test targets where even recognized when they wore masks and capes, hats etc.

But what was not told was that the false positive rate while percentage wise small (I think <1%) with the amount of expected non-match samples was still making it hardly usable.

E.g. one of the train stations where I live has ~250.000 people passing through it every day, even just a false positive rate of 0.1% would be 250 wrong alarms, for one train station every single day. This is for a single train station. If you scale your search to more wider area you now have way higher numbers (and lets not just look at population size but also that many people might be falsely recognized many times during a single travel).

AFIK the claimed false positive rate is often in the range of 0.01%-0.1% BUT when this system are independently tested in real world context the found false positive rate is often more like 1%-10%.

So what does that mean?

It means that if you have a fixed set of video to check (e.g. close to where a accident happened around +- idk. 2h of a incident) you can use such systems to pre-filter video and then post process the results over a duration of many hours.

But if you try find a person in a nation of >300 Million who doesn't want to be found and missed the initial time frame where you can rely on them to be close by the a known location then you will be flooded by such a amount of false positives that it becomes practically not very useful.

I mean you still can have a lucky hit.
It’s not consent if you’re not allowed to say no.
It looks that way because we're all in a filter bubble, but I don't think there's much evidence that people generally support murdering executives as a productive theory of change. What you can say is that Twitter feels unified on this --- and even then that's a vibe, not a fact.
> Meanwhile, deployments keep getting rolled back?

One could say that the scenario as described in the post I originally responded to, by localghost3000, doesn't make sense, yes. If there have already been multiple rollbacks, and this is the first conversation you as a manager are having about them with this report, then you as a manager have already messed up by not addressing the issue sooner.

But that just makes it even more of a problem to lead with language like "quality issues in your code", implying that all the responsibility lies with the report, and none of it lies with you, the manager. The approach I described, where you focus first on the objective fact, that the rollbacks happened, and on how to keep them from happening again, avoids that.
> it's actually publishers who won't put up micropayments on their content

Won't, or can't?

Do you have a good article about how to set up a paywall or tip jar for small transactions, with a clear description of what percentage goes to middlemen and (mainly in the case of proof of work) how much externality cost it incurs?

I would like to be able to pay $cents or even $dollar for instant access to an article, but only if X% actually goes to the recipient (I don't know what X is, yet), and I would lead by example on my own content. (though most likely tip jar, not paywall)

What I've heard — and I don't claim any real expertise — is that the city was built by a significant amount of private money and certainly private companies, and what made the city fail was several different governments all deciding that they didn't want this sort of thing, specifically China wanting houses to not be investments and restricting how much money Chinese citizens could take out of the country, while Malaysia started off in favour of it but then decided that "foreigners" (which in the face of Forest City would have been Chinese) shouldn't be buying up housing in Malaysia.

That's not really a sign of central planning failure, any more than, say, California City — failure, sure, but not due to what distinguishes economic central planning from capitalist diversity's self-balancing.

Well they are bringing “demand for wind farms” and whether that is good or bad or neutral is a matter of analysis.

I don’t personally care for or have any bitcoin or crypto, but I suppose it’s interesting to think about how that functions as a general speculative commodity and how that type of speculation compares to the other types in the economy. A first order analysis might say “buying real assets like grain commodities does more for the economy than buying what amounts to burned up megawatts”, though it is interesting to consider how bitcoin has affected the demand for new electricity build out. We have heard some horror stories of carbon intensive bitcoin mining but there is also more demand for electricity in general and electricity providers will spend some of their build out on green technologies.

All that said I’m pessimistic that simply burning megawatts as a form of market demand generation is even remotely optimal. In my view direct government investment in green energy buildouts would be more economically efficient and environmentally beneficial (I’ve not yet studied how China is doing it but if I wanted to know more about what’s possible I’d certainly research what they are doing). It is probably fair to say “bitcoin as a means of stimulating green energy growth is a poor allocation of finite resources”.

So maybe the net value is zero or negative. But there is some value and some harm this type of thing invites.
