Unfortunately absolutely not, for many reasons:

1. A neural network with ReLU activations (the most common one) effectively has a piecewise linear optimisation surface, so the 2nd derivative is 0 almost everywhere. No curvature, no Hessian.

2. 2nd order methods make an assumption that the optimisation surface is (close to) convex, which is very much not the case with neural networks.

3. Even if the above were not true, to measure the Hessian you would have to iterate through the entire training set to measure it before you could make take an optimisation step.

4. Representing the entire Hessian for a network with N parameters needs O(N²) space, where N is on the order of 10⁹, so you couldn't use a method that needs the whole Hessian. There are so-called Quasi-Newton methods that need O(N) space though, like L-BFGS.

Neural networks need completely different optimisation methods, and there is no practically useful application of any of the Newton or Quasi-Newton methods for their optimisation.

I can empathize with the customer here. I have also seen it from the other end, working for a large and slow SAAS organization. I see PMs always wanting to show the customer the "roadmap" because they think it somehow appeases the customer and calms their wrath. The wiser customers know that a roadmap is not a promise, and will take it with a huge grain of salt. I have grown to almost despise the word or mention of it. Quit with the meetings and compliance reviews and politics and just get stuff done for god's sakes.
Steve Jones mentioned why he chose mechanical, it stored more songs, in 2002 you didn’t have many gigabytes. The iPod was the size of a deck of cards, it wasn’t much larger. You listed an MP3 player you needed to add storage to, when SD cards were 8mb or 16mb for the period.

You could get 2GB flash on the iPod nano. I wouldn’t have liked the nex one, the battery life was probably worst, the iPods had good monochrome at the beginning, and the good ones they were fighting were the rio karma which also used HDD, battery, and the Archos were good too, and no different aside from the iPod needing iTunes.
I just completed a job search and probably focused on salary a lot more than I should (although it worked out in the end) simply because I was unwilling to ask a ton of details to figure out the value of the various benefits.

One of the challenges is that as a candidate, it is hard to know how real the perks are and whether they will stick around. One company I know advertised a choice of dev hardware, specifically a 17 inch PC or a 15.6 inch PC. No real choice. My past company had semi-private offices, until we grew and everyone was put into a new noisy single room open office, with everyone, including execs, taking meetings at their desks.

Sure, you might like one manager over another, but they will probably be gone in a year anyway. In my two and a half year career at three companies, I have worked for 6 people.

With valuing health care plans, at least in Canada, so much of the value comes from the specifics and your specific needs. My employer has unlimited and 100% drug coverage. If you are chronically ill, that could be worth $20,000 dollars a year. Great dental too. But if your need is physiotherapy, I actually have the worst plan I have ever had, capped at 90% reimbursement up to $500. Same with mental health needs. 90% capped to $500 for therapy.

Valuation of these things is messy, so people just go with salary.

Wonder if Elon would choose to address the main issue of Fertility in the Western World. Since more and more Men and Women are having difficulties conceiving. With the increasing costs of Fertility and IVF treatments citizens are finding it hard to come up with money to have children.

Meanwhile the US and Canadian governments are not dealing with this problem. Perhaps leadership should start to address the problems that their citizens cannot have children and do something financially to assist families in need. Instead it seems that Canada is continuing to just fill the population with refugees and immigration.

I'll play devil's advocate here and say that sometimes these incidents deserve praise because they uncovered an issue that was otherwise unknown previously. Also if the incident had a large negative impact then it shows to leadership how critical normal operation of that service is. Even if you were the cause of the issue, the fact that you fixed it and kept the critical service operating the rest of the time, is worth something good.

Coloring with Code – A Programmatic Approach to Design
IMO there are (almost) never too many scientists. Yes there will be junk science. In fact most findings are false or offer nothing new. The few that are true form the basis of the progress that mankind has made.

That aside, I think two more reason for the reproducibility crisis are

(1) the restriction on papers lengths by journals. I remember having to cut so much stuff out of my fist papers just to get it down to the 12 or so pages that I was limited to. When I finally finished I thought to myself "I pity the fool that tries to implement this technique based on such paltry information"

(2) Some researchers will not share all material and methods because they wish to stay ahead of the competition. I know this from experience.
I would much prefer it actually and in practice many days I do. I will also work a lot at night.

The reason I prefer it is that I can just focus on that one thing and keep the context in my head. Even very degraded, I seemingly can get a lot of work done simply by having lots of focus time rather than being interrupted every hour or so.

This sounds like the opposite, actually (in part, and in part like an instance of my “only” caveat above—many things you can’t do with Glibc alone, and other people are much worse at versioning): it’s bundling its own old libm (part of Glibc) instead of using the system one, but at the same time is trying to link to the system libasound, which expects a new libm and predictably fails (note that only one libm can exist in a given process, though different modules can refer to different symbol versions within).

The Ballistics packaging people got it exactly backwards, in other words: Glibc is the thing you least want to bundle unless you’re bringing the entirety of the environment with you (including things like libGL and libX11). Try just removing the offending libm, maybe? Then the loader should probably fall back to the system one, given that it’s finding a system libasound, and that’s what you want.

I just wanna know where the hell local ads are any more, lately it really strikes me how much a megacorporate desert the ads on streaming services are are - where's the low-budget ads for the local mattress discount outlet with the owner dressing up in a goofy costume, where's the furniture chain with a jingle the owner's daughter (who is now the current owner) sang when she was six, where's the spots for local events, where's the local SPCA showing me cute shelter cats, all of that stuff? Those used to be scattered amongst the spots for global corporations. Now they're gone.

The reasons why they did the pivot were mis-represented. They said they were doing it. They did a very poor job of justifying it in cost/benefit terms which a public agency like CSIRO can work with.

It is understood CSIRO has a strong bias now to self-funded work, which goes to commercialisation. its dogged it since the formation. The problem is that the IPR vesting and profit outcomes of work done can sometimes be misunderstood against wider gains. Standards work (for instance) often generate no profit. Does that mean CSIRO should stop doing them?

Data61 "was" formal methods. A lot of their work was in proofs. They applied the proofs to etherium, and they generated a huge amount of interest in formally verified blockchain contracts (which btw I think are bunkum) but the actual value was in the understanding of proof systems and verification. Australia is going into the Aerospace sector quite heavily. This is an area where verified systems are very important.

The "AI" component of proof is slim. Arguably there is an ML component, but having continued role in SEL and trusted platforms and applying proof systems and verification was a good thing in my opinion, and was not justified in being ditched. It looks to me like a poor long-term engagement strategy to walk away from a foundation.
> You might be misunderstanding. They parent may be saying that they download the maps and just search for a road and use it like a paper map.

Maybe? When hiking it makes some sense to forego GPS to save battery power. I didn't consider that possibility when I commented earlier, but in my defense the context of the comment is using maps without an internet connection.

I think the difference is that Teamviewer/AnyDesk is intended mostly for corporate usage. Their software is optimised for images that are mostly static, letting them get away with much less bandwidth without making text blurry or illegible. Standard H.264/H.265 encoded video needs sharpening and extra filters to be both low bandwidth and legible in many cases.

Parsec and friends use more bandwidth and hardware resources to get a stream going, but that stream is of much higher quality. You probably won't be running a fully-staffed remote support company over DSL or basic cable with Parsec, but with Teamviewer you just might. I've made several remote support connections at the same time on ≤8Mbps down on a simple Core i3, you just can't get that done with a game streaming solution like Parsec. Modern streaming services also require hardware encoding support or their CPU requirements are huge, and the endpoints support software often connect to isn't that powerful.

Microsoft's RDP solution in excellent on all fronts, though. Normal H.264 encoding for moving content and static-optimized codecs for office machines, all with heuristics to switch codecs on the fly. Sadly, this is all locked away behind licenses for consumer devices, but the technology is there.

but yeah wal file are probably the culprint here.
btw. most of the time it's not just aws rds, as somebody else stated a few things in postgres do happen to write data into wal files.

there is a lot more to it and depending on the config and replication it can behave a little bit differntly i.e. under normal use these files can get reused depending on min_wal_size/max_wal_size,etc... it's quite a complex thing and normally do not need to be fine tuned.

I'm also pretty sure the behavior changed in more recent versions (which probably made it worse in this scenario, but more default safety for everbody.)

And I agree with what you’re saying, too. I don’t think it’s relevant to music that many musicians are poor, but I think it’s relevant to what I thought was being discussed.

I'm not seeing from the error message how that qualifies as a glibc symbol compat issue as such. On the face of it, it looks like the application is vendoring its own libm rather than using the system glibc's libm, and then it tries to load other system libraries which expect to load the newer system libm and instead find an older one.

If my interpretation is correct, then if it's going to load system libraries, those may require system glibc, and if it's going to use system glibc, it should use all system glibc rather than trying to mix and match.
I get what you are saying.

I have found the opposite though, but not on new hires.

On new hirers the employee is looking at money, and reputation.

I have seen guys stay in mediocre companies for years because they like the owners, and the managers.

A place can have a lot of perks, but if the employee doesn't feel like they are family/team; you will have an employee that does the bare minimum, or tries to sabotage at worse.

Those middle managers whom are terrible with people are poison to the company.

I used to work for a restaurant consultant firm. I basically got the job because I spent way to much time hiding out in school, and was a cook in high school.

Our job was to go in as customers and find out why the business was mediocre. We also looked at the accounting. (This was before cameras were everywhere.)

I did feel like a weasel, but told my boss employee theft is not part of my job. I will not go to court, or even turn in tap tillers (guys basically stealing). The restaurant industry is rife with theft.

My boss's attitude was basically try to turn over help every six months. It's cruel, but effective.

I noticed a trend. On pretty much every fledgling site I went to, there was one, or two, people who made the staff angry. The employees seemed to take it out on the restaurant.

They were all middle manager types.

I once went into this bar in SF that used to be profitable. I went there a few times. There was this one bartender/manager who was nice initially, but had a very bad side to her. She literally alienated 90% of the staff. Even customers did not want to deal with her.

She was a friend of the owner. She was the queen of Mixology (Her title), and mean. She had something nasty to say all the time, but was cagey. When someone was watching her, she was Dorothy from the Wizard of Oz.

I told my boss the problem, but the owner never fired her.

I left the job after a few months.

Most of the restrants failed because they were in the wrong location, or food wasen't right, but there were places that went down to one, or two, toxic people.
Unmatched cost-application(utility)-need = tiny pool of buyers.
Some needed it, some could afford it, some had a use for it. Cost was the major hill, lower that hill and more would buy, get it really low and the people that play with things, games etc would buy in.

I've used GPS navigation extensively on my phone with no internet service; I drove clear across Canada with my simcard pulled, it works fine.

If I had to guess, these conflations of cell service with GPS are a product of misleading UX created by Google. OSMAnd makes the nature of GPS clear, displaying a count of satellites it's managed to hear. Enough satellites to get a location good enough for car navigation almost always takes less than a minute.
Fascinating! Going to use this in one of my projects.
> But you can’t guarantee it.

The fundamental logic error in the justification for tests is that I don't need to guarantee that the issue will never reoccur. A reasonable level of confidence is more than sufficient for most projects, most of the time.

As an example of an environment where automated tests are critical: I read a post by someone complaining that when they worked at Oracle the automated test suite ran through hundreds of thousands of individual tests and took hours despite using a huge farm of servers.

That guy was wrong! I would absolutely test something like a commercial RDBMS to death. Those tests are not optional. Similarly, if I was developing a file system such as ZFS, I would also test the heck out of it. Famously, Sun had a test lab where robots would physically pull drives out of servers!

But would I test a typical web form with automated tests? No. It's boring CRUD code. It's going to work, because I use parametrised queries using strongly-typed ORM to a CotS database platform using "boring" code paths that are well known to work. If the DB schema changes, the build will fail.

I'm more interested in testing if the form UX layout "looks pretty" and has a "nice layout to help the workflow." Ensuring those will also exercise the boring parts of the back end code anyway as I click through the form a bunch of times.

Once the code has been established as working, and strong typing is used end-to-end, why bother testing it over and over?
This is why my company has custom applications that talk to the ERP for certain departments. Inventory control in the ERP isn’t going to work with reality. The data modeling is good enough but the interface is not.

Rather than train everyone we hire to use horrifically bad and expensive barcode readers, we purchased cheap smart phones, put them in cases, and locked them down to run an app that uses the camera to scan barcodes. Drop a phone? It’s encased in rubber. Run it over with a forklift? Toss them another one from the box and then figure out why this only happens on Tuesday afternoons.

We already need a dev team for other reasons. Adding another decent programmer to create and support internal apps isn’t that expensive in the long run. Plenty of good devs like me who are happy to work remote from the Midwest at less than FAANG rates. :)

>professionals are going to want to see the rounded “actual” values

Ideally, a generalised design tool should cater for rounding to 8bit and other meaningful precisions, or keeping source data intact.

All we’re talking about is _allowing_ for a user to type in a fractional number, and for it to be kept. It’s not a difficult request, and it doesn’t negatively affect normal use for people who don’t even know the feature exists. They can continue typing in integers.

If we’re talking about software design, it’s likely that in many situations the buffer being rendered into will be deeper than 8bit per channel, so even covering 0-255 is not enough.
