We’ve just moved to Snowflake. I haven’t really been impressed with some of the new features added to Redshift, it seems like too little and too late.

The JSON support (SUPER type) is kind of cool, and they are moving towards more “automatic” sorting + partitioning, but it’s just all a bit shit to be honest.

We encountered major bugs with data-sharing, our clusters keep insisting that zstd is the best compression format to use for all our data (but then never actually using it), materialised views often fail to update and understanding why is a nightmare, terrible performance if your strings are varchar(max) (guess what Glue sets them to…), Redshift data often just dies (4 hour downtime recently, no status page) and has some really weird semantics around listing queries, before the data API you couldn’t run async queries and it’s eventbridge integration straight up doesn’t work, nightmare bugs in the Java connection library that don’t show up using psql, tiny set of types (no arrays, uuids), unkillable queries, AQUA actually causing everything to slow down hugely, critical release notes posted only in a fucking random forum, etc etc.

Snowflake has apparently sorted this, as well as including ingestion tools (snowpipe) that you’d otherwise have to stitch together with AWS Glue or something (a cursed service if ever there was one).

That being said, in some cases Redshift absolutely flies. But the real world isn’t filled with ideal schemas and natural sort keys. It’s messy. And Snowflake deals with messy better.
Apple has both an SDK for turning a series of photos into 3D models and scenes, as well as LIDAR sensors in their high-end phones and iPads. Notably, though, last I checked these are separate initiatives and the SDK doesn’t use the LIDAR data, but depth information the camera gathers by using two of its lenses.

If a game doesn't want TCP at all for whatever performance metrics they think they need to hit in their networking stack, HTTP/3 is not likely to meet their needs/standards/expectations either even over UDP because HTTP/3 just moves some of TCP's stack into the application protocol over top of UDP and in some ways remains "just" a TCP-over-UDP tunnel.
Getting and spend coin in the early days was the draw. Too much money poured in making everyone afraid to spend because everything is worth so much. I remember people dropping coin in reddit to anyone with a positive comment.
From the hiring side, I've seen some help the candidate cheat the interview.

In my experience on both ends, they don't care about good fit nor qualifications. It's a numbers game - throw almost any candidate at a position to hope it gets filled, or contact as many devs as possible to make them a client.

Recruiters that are actually part of the company tend to be better in my experience. I won't even talk to 3rd party recruiters.

Point taken, but jeez, Hackathons are supposed to be participatory/inclusive events. Feels a bit harsh and counter-productive to just tell back end devs to kick rocks. Full disclosure I am running a hackathon at my company this very week and am nervous about participation and this post made me anxious lol.

*For one very narrow definition of Hackathon

Seems like the author needs to attend Hackathons where the sole purpose isn't to sell a SaaS prototype to investors and clients. I have been to enough of them where no one cares how fancy the CSS styling on the page looks. Or even that there's a GUI at all. One time the winner wrote a CLI script.

Sounds like they are selling Wifi++ - what confuses me is how/why Amazon is involved, apart from selling the hardware. Is there a subscription piece?

The implication of this product concerns me, although maybe it's just a communication issue. Amazon is selling this as an Amazon product, but wifi isn't an Amazon product, nor is 5G. They are retailing the gear to put up a 5G network - so why call it a "product" and roll it out like this?

"Not to mention you will never--and I mean never--get people of a certain temperament to go along with an ever-changing set of rules designed to inflict zero emotional distress."

Why not? Because they'll throw tantrums, whining about how it's just so unfair that they can't call people stupid? Too bad. They can suck it up and do their jobs- a part of which is effective communication- or they can leave.
The trick is to find an active community where they know their stuff and will downvote/delete spam. Unfortunately those needs to be extremist for their hobby and so they will look down on perfectly fine for normal use low budget things.

CaaS: Cortisol as a service
I think this is moving the goalposts. Yes, I agree that nonverbal communication matters. And I understand it's possible there is some code to communication, similar to how different cultures use words differently. But that's not what's being discussed.

"That's stupid" is referring to something being stupid, not someone. You need to invent additional context to interpret this differently.

Almost always as a rule they are. You are not going to get people to vote for a union security clause that decreases net pay.
> The results keep getting "refined" so as to suit the popular 80% of queries, while getting much worse for any technical or obscure queries.

The fundamental, unavoidable problem is that the cost of providing high-quality results on the long-tail of possible searches tends to grow faster than the revenues that can be earned from those increasingly rare, obscure, long-tail searches. Any search service seeking to maximize profit, like Google or DDG, ultimately always evolves to perform less and less well on the long tail of possible searches.

The search service we all wish we could have -- a service seeking to maximize the quality of individual searches, no matter how obscure -- may not be feasible as a profit-maximizing business.

The reason I would prefer not to mark as "not interested" is that there is so much content that is being produced by channels that I subscribe to that I never get recommended to me.

If you put it that way you make it too simple. The question is whether I want a second, smaller computer inside my larger computer that may at any time corrupt memory, monkey with network frames, turn off the power, assert PROCHOT, or do a million other bad things. It's not just a tool with benefits. It has both benefits and risks, and in my experience the risks are not worth those benefits.
Presumably they sell network management/operation/maintenance/... as a service. (Similar to how cloud-managed wifi stuff is a thing, except mobile networks are more complex)
It reminds me that we don't see "floating" touchscreens anymore.

The Galaxy S5, and probably other phones had this feature where you could actually trigger hover targets by hovering your finger above the screen. I just tried it on my Galaxy S5 the linked page and it works flawlessly.

It may be one of the gimmicks Samsung loved to put in their phones at the time, but as we can see, it is not completely useless. And it also doesn't look like there is any downside to it, except maybe a very small increase in price.

I think you are still under the impression that success is still based on codebase and you just need the perfect source code to build the most successful service. That's wrong. Success is built on relentless labor, continuous marketing and luck. That's why Gitlab can build a successful company while dailymotion can fail to build what is functionally not new.
"To make use of multiple NICs I needed multiple NFS connections per NIC."

What? I presume "multiple NFS connections per host." was meant. Not sure what those NFS connections are supposed to be though. NFSv3 is (stateless) request/response protocol on top of TCP/IP connections. NFSv4 introduced sessions, but here NFSv3 was used, wasn't it?

It's been said that every dollar on the internet has been made by unbundling and rebundling products. In the US, cellular started as a service that was dominated by regional players and now it's essentially a 3 company monopoly. In the same way FinTech's have gone after traditional banks, I can see business models of providing regional or niche cell phone services.
It's giving me better results than Google. I'll try it for some time. Thanks.
> lmfao. so you're telling me "quantitatively" that google search results have gotten better, without citing any data at all, but with an appeal to common sense and "technological advancement"?

Yes. If that sounds so unacceptable or strange to you, I suggest you try it. Works really well when reasoning about unavailable data, or researching a field with slow peer-review process.

> what if i told you that search is an adversarial problem

Then I get an adversarial reaction and a downvote from you.

> it's possible for google's tech to be getting better slower than the aggregate tech power used to game google search is getting better? is this not a patently obvious possibility?

Yes, that's plausible. Should be measurable quantitively too. Can you cite some data on this? :)

We could compare to the available data on the quality of (HTML) e-mail spam filtering over the years, which all have kept up. Like pg said: Spam is solved, when skilled spammers start creating content which does not look, feel, or talk like spam. So webcontent-spammers still are on the first 2 pages of Google, but with content not classifiable as spam/content farm.

> which benefit google's interests rather than their users.

One of Google's interest is their user. But perhaps not the type of user you are. Studies have shown the value that the tech of Google is delivering its users per year. This value was in the thousandths, and this value has risen. Meanwhile, Google makes about tens of dollars per user per year, less for technical users which don't click ads or block these.

> it's not some kind of gotcha impossibility for google's tech to get much worse over time

It really is, no way to mince it. Google search is funded by Google ad tech. Google ad tech has improved ML by a ton. To say Google tech is getting worse, is to totally overlook deep learning revolution, word2vec, transformers, BERT, etc. etc. etc. To state that, is to reveal the truth that you are ignorant of major technological advances in the past decade, only looking at the issue from the viewpoint of a single atypical Google-search user. What would you even do with quantitive SEQ data?

Do you really think it is possible that Google runs an implementation test of a new ranking model, and deploys it, while all measurements, human labeling, and user tests show it is doing worse? Of course not! Only if you think you are smarter, could you think that Google search changed and has gotten worse.

If Google does ML like the rest of the industry, all model changes move up their designed levers, or these changes are not committed. So if Google was unable to improve search, then Google would have looked exactly like 2008 Google. The fact that it does not, shows either you or Google is wrong. If I had to make a bet...
My organization's most recent hack day was won by the UX team signing up for a free demo of a chat bot service and demoing it - not a single line of code. We haven't had one since, nor do we use chat bots anywhere in our org a few years later.
What do you mean "too late"? Redshift was released in 2012.

Edit for future readers: the original comment was "I haven’t really been impressed with Redshift, it seems like too little and too late".
I am sure it is possible to surprise with a search service that is as much better as Google were to it's competition when it launched. I have no idea how to build it, but given that Google eqrch as of today is not very good, it must be possible.

I think the idea is that AWS is slimy for rejecting a deal with a startup and then launching a competitive product. There's a difference between independently coming up with an idea versus transparently copying someone else's idea. Of course, we can't be certain that the AWS folks who launched Private 5g were even aware of the Soracom deal offer, but the optics certainly aren't favorable.
Thanks for this, it looks quite usable.
CI/CD's must be stupid simple to work with and that's their entire purpose: you should not waste time with clicking and scrolling and dealing with custom setups. Even Jenkins, which is dog shit and I've had to use in the past was light years ahead. Have a look at gitlab, github, circleci and all the big players in the field - the exact same task takes considerably less time, documentation is perfect, whatever you want to achieve is no more than 5 lines of YAML away, the UI isn't something from a 2 year old's sketchbook, the outputs are actually clever enough to work out when and where a test for instance failed and take you directly to the relevant section of the log rather than having to click "show more" and scroll up 20 times. The email notifications it sends are practically useless - they are basically images of the static noise coming from the big bang, except they clutter your inbox. And to think the company was paying close to 3000€ per year for this crap genuinely baffles me when you have an endless amount of free and open source alternatives that actually work.
I've never seen anyone do what the author is writing about.
I think there's a reasonable argument there, but I can understand the model better before the internet (since distribution was way harder and more expensive). The terms were definitely bad for talent because early talent had no leverage before the internet (and couldn't coordinate).

After the internet whatever argument the record companies had was way weaker and their unwillingness to update (instead attempting to fight everything legally) cost them enormous returns.
N2 has BFloat16 instructions. EDIT: I probably should have a citation: https://developer.arm.com/documentation/PJDOC-466751330-1825...

Page 50 of 92 shows off BFCVTN, BFDOT, BFMMLA (matrix multiply and accumulate), BFCVT, and other BF16 instructions on the N2.

I'd assume this Graviton 3 is a N2 core. But that's just me assuming.
Most of those "real opinions" are not real opinions.

I've been on both sides of paid reviews on Reddit.

Athena is not BigQuery. Athena is just a fancy wrapper around Hive (you can see this right from the log output) and just runs map reduce over your S3 data. It's a great tool for what it is.

BigQuery is a full database. It is significantly faster than running anything from Athena. The closest comparison on AWS is Redshift.
I’ve been using DDG for sometime now and can attest, it’s results are very good for technical queries. It’s fast and private.

> Much depends on just how open those windows are. "All windows wide open in every classroom" during very warm or very cold weather is excessive

During a pandemic, it makes a lot of sense-- at least for the "extremes" of weather faced here.

> A window cracked open for ventilation, and either at the top of the classroom (warm weather w/ cooling active) or bottom (with heating), and a fan within the room for vertical mixing ... might help.

Might, but who knows how much? How does one weight the ordinary risk of sickness and infection (outside of a pandemic) with energy costs? (Especially when there are less energy-intensive ways to get the ventilation).

> A slight improvement is to have a single exit point (vented with a fan) and rely on structure permiability to introduce fresh air. That's effectively a negative-pressure system.

> From there, exhaust and intake with heat recovery is the next obvious step.

Yes, and pretty quickly from here you're ending up designing a structure without windows that open, so you can ensure that your fancy ventilation system does the right thing, filters don't get fouled, and you're not wasting heat.

> I mention older construction as replacing building stock is a long-term and expensive process.

Well, sure. But we were talking about it in the context of someone complaining a new building doesn't have windows. Older, smaller, poorly sealed buildings are a lot less likely to be retrofitted with no windows than new construction.

> It also recommends on exhaust fans rather than interior circulation fans to minimise strong internal air currents, with intake provide as I've indicated above.

Well, duh.

An otherwise well-sealed building, with a porous wall structure held at a small negative prssure, is effectively a very simple heat recovery ventilation system, too.

> On grounds having being state controlled? I'm not sure US regulators do have that power. On some pretend grounds, to be able to wield it as a geopolitical weapon? Probably not.

overall, the Commerce Clause in article I of the US constitution grants the federal government power to regulate commerce with foreign nations, which includes import / export restrictions. For example you can't really buy things from Iran or Cuba without major restrictions if at all.

if a trade embargo doesn't fall under the realm of "geopolitical weapon" I don't know what does.

What exactly makes you think that? If covid disease gets a refresh every couple years like the flu does, it's not impossible that we never, ever get rid of it. It could just become a disease you just expect to get once you're older, unless humans as a species grow immune to it (read that as: lots of us die and only people with resistance to the virus get to breed for a generation or two).
