A significant portion of the first two years of a typical Bachelor's degree program are very liberal arts heavy with a generous sprinkling of electives. These classes may deliver some value to the individual, but it is questionable how much they add to your skillset as a software developer. Also a bootcamp is a very compressed format, versus a typical college schedule.

On top of all of this there is also the elephant in the room that the cost of college has become so great that the value proposition isn't the same as it was in the past. If I can learn even 75% of what I could learn from a college at a bootcamp for a fraction of the price, does it still make sense to choose college?
Hi, thanks for the response.

30 years of being in tech and startups. Previously deployed, managed and optimized 150,000 GPUs across 7 data centers.

Power usage has changed quite a bit, such that we see articles now about how older datacenters power rack density doesn't work any more [0]. Each of our MI300x boxes are 7KW. That doesn't work with only a 20amp circuit to your rack.

Liquid cooling has been in development for ages, but is now being pushed to the front due to the higher power requirements of the servers. We have to lower the PUE, in order to increase rack density. This increases complexity through the entire supply chain.

Networking is more complicated. For example, we are running into sonic software issues with the need to deploy VRF to support multiple customers, and it is buggy AF in some implementations from some vendors. NICs no longer talk to CPUs, they talk directly to GPUs (RoCE), and that has more interconnects (8x), along with the way they are connected and managed at the switches. One design even puts each GPU on a separate switch, requiring even more cables. When you are at 400G/800G, which chip you choose in your switch matters.

Relationships. Dealing with multiple vendors, supply chain issues, finding power/space, all these are more complicated now that demand is far far higher. 6 years ago, Cenly Chen from Supermicro said AI spend in 2025 would be $36B [1]. Current estimates now are $750B+.

You can't just order a box of MI300x from your local BestBuy. These things are export controlled by the US govt and effectively classified as weapons with restricted usage. We have to KYC our customers.

This is just the tip of the iceberg, I could go on and on... now that I'm in the thick of things, I feel pretty confident that we are providing a pretty necessary service. Especially at the scale we are building for.

It was just a simple observation. You are reading into things too much. There's no need to be so defensive. Your comment hasn't upset me in the slightest ( rationally or irrationally ) and I sincerely hope you weren't offended by mine.
> With as much margin as cloud takes, there will be increased interest in on-prem and mixed environments.

Or cheaper clouds...

I wonder how much lock-in the current clouds actually have. And if they'll fully take customers down or entire industries hostage like the mainframes did.
I wonder why the cost of running on the cloud, engineering cost included, is not a concern to companies. Per DHH, even a modest app like 37Sigal's would cost millions more than they liked (https://world.hey.com/dhh/we-have-left-the-cloud-251760fb)

On the other hand, as increasingly only a few cloud companies know how to build out datacenters, maybe the talent pool for building datacenters will keep shrinking - a vicious cycle in which fewer companies will choose to go with their own data centers.
> To be honest most of you will be fine running a single dedicated bare-metal server

Someone that says this has never even reflected about availability requirements.
That's just raging idiocy, not a worthy article.
I can explain why the kids with A names outperform the kids with Z names.

As someone whose first and last names are both very early in the alphabet, I was always called on first or second when I was in elementary school and middle school. I always had to be there early.

My friend whose name was very late in the alphabet learned he did not have to be ready for the first minute or two of class.

He would be standing near the door talking as I was quickly pulling out last night's homework, and I would be marked down for not being ready while he would later be commended for being ready when the teacher called his name.

As a teacher, I see that the kids who stand outside the door talking do not do as well as the kids who are there early.
I pay a colo for power (which also covers cooling) and the costs are still waaaay less expensive than EC2; orders of magnitude less. Like <300USD a month (amortized) for hundreds of cores, hundreds of gb of ram, hundreds of tb of disk space. The same costs for a EC2 instances (reserved 3yr, so it compares nicely) is thousands of USD per month.
Here's a link to the language itself. Hasn't been updated in a couple years, unfortunately. Maybe getting some attention here could help.

This is the same argument that mainframe companies made in the 80s. Mass commodity systems will eventually kill the big gpu except for legacy and niche workloads. It's the tech infra circle of life.
It's easy to get what's going on once you realise it's a sickness industry, nothing to do with health.

You want lots of sick people to treat a lot. Doctors being short on time etc, is fine - it's business.
I don't think he denied that.
This pdonis is a jackass - here are direct quotes from Dennett:

- "There is no reality of consciousness independent of the effects of various vehicles of content on subsequent action (and hence, of course, on memory)." - from Consciousness Explained, page 132.

On page 113 he says:

- "Unlike mental states taxonomized folk psychologically, "content-fixations" are each precisely locatable in both space and time".

^ he is saying mental states are not locatable in space and time.

Page 138:

- "There are no fixed facts about the stream of consciousness independent of particular probes"

An interview:

- "The reason [consciousness] is so puzzling is that people think they ought to be able to study it from the inside, using pure phenomenology, those give you hints but they are illusory. That's not what's really going on."

Source for this interview (New Scientist): https://www.youtube.com/watch?v=wm8M_xQrgCk

From David Rosenthal's Content, Interpretation, and Consciouness:

- "There is good reason, in any case, to construe Dennett's pandemonium model as positing only subpersonal events of content fixation, rather than full-fledged intentional states. Thus he writes:

"We replace the division into discrete contentful states-beliefs, meta-beliefs, and so forthwith a process that serves, over time, to ensure a good fit between an entity's internal information-bearing events and the entity's capacity to express (some of) the information in those events in speech. [10]

10: Dennett speaks throughout Consciousness Explained of such nonconscious, subpersonal events

Wikipedia on Multiple Drafts:

- "Dennett argues that [consciousness theories] share a common error in supposing that there is a special time and place where unconscious processing becomes consciously experienced, entering into what Dennett calls the "Cartesian theatre".

A couple more Dennett quotes:

- "There does not exist ... a process such as 'recruitment of consciousness' (into what?), nor any place where the 'vehicle's arrival' is recognized (by whom?)"

- "the Multiple Drafts model goes on to claim that the brain does not bother 'constructing' any representations..."

I could go on forever because this was his main jam. I find it hilarious this pdonis person has such a high karma/score/whatever on this site after such awful takes.

I won't even get into Searle who pdonis just Googled for the first time, bringing up Chinese Room (1980) as if it's a scientific theory. What a joke, I wish he could be downvoted.
Mmm, if you said Cruise I'd be on board, but Waymo is my primary mode of transportation around SF these days.
I applied 9 times and never got an interview. I've moved on from entrepreneurship (for now?), but would love to know what percentile I'm in for consecutive rejections as a consolation prize ;)
Waymo is amazing and has fully replaced Uber for me in SF. They're also expanding to the entire peninsula from SF down to Cupertino - you're out of date on this.

Waymo driving in SF is way better than human. It's not timid either.

This Mercedes post is marketing - it's not really what people consider autonomous given the constraints.

> "Drivers can activate Mercedes's technology, called Drive Pilot, when certain conditions are met, including in heavy traffic jams, during the daytime, on specific California and Nevada freeways, and when the car is traveling less than 40 mph. Drivers can focus on other activities until the vehicle alerts them to resume control. The technology does not work on roads that haven't been pre-approved by Mercedes, including on freeways in other states."

The above makes it nearly useless and far less useful than what Tesla has been shipping for years imo.
https://en.wikipedia.org/wiki/Zelda_Williams
"potential in the space?"

If you read the article, they essentially just have Tesla Autopilot with self insurance and driver monitoring removed.

This "landmark achievement" only works on freeways and under 40 mph.
very refreshing to read. theres just so much complexity behind myriad of decisions just to build simple apps/websites and this is not a coincidence.

by draining cognitive resources you are able to manipulate people into making poor quality decisions. ex) mainstream news, aisle of grocery items, FANG-led development mythos and over-engineering

the last one is especially susceptible to manipulation.

"but we have to scale", "i read HN article from an ivy league founder", "someone with lot of followers on twitter said so"

and boom you are no longer in control of your mind or aware of losing control.

marketing is just like herding cattles, DDOS their cognitive resources so they can't think for themselves and gaslight each other, make them use your npm/pip package with a subscription/metering from day 1, get em while they are young.
Rail systems could and if you look for it, already do form gutters along the panel-to-panel seams to not drip water inside the contiguous array area.

Still cheaper than a metal roof intermediate layer, though.
But in places like Germany overhead glass outside of some limited applications (notably greenhouses for farming) isn't allowed to drop on anyone's head just from a sharp pebble impacting and cracking a glass layer. Sadly the regulations are just as strict for a home carport/garage-without-door as for a majestic train station hall. So aside from the worse cooling it's in practice cheaper to just use a corrugated sheet metal layer to catch rain and falling glass, with the structural support for both unified.
Because in reality the two party system is not accurate. It’s rich versus poor, those with power versus those without. Nobility versus peasants. That’s just how it works.

I did:

"empiricism is an epistemological view which holds that true knowledge or justification comes only or primarily from sensory experience and empirical evidence."

Note the phrase "or primarily".

> knowledge is combination of empirical and rational sources

The "or primarily" hedge is all I need to refute you (or at least to show that we are not actually in disagreement). However, rationality can itself be justified by empiricism if the Church-Turing thesis is correct, which I believe it is.
I don't think many people use their phone contact list like that.
Thanks for the info! Glad to see I'm not the only one thinking it was a weird path to take.
Anki is outdated, here's a donkey?
I was using Anki flashcards since my university years. I even learned English with it but now it feels outdated both by design and features. So I’ve made a replacement for myself and enjoyed it. Now I’m making it publicly available with some AI features. All features work well but personally I’m in love with simplicity in the design. Here’s Anki Donkey :)
Sure, everyone knows Waymo's schedule has slipped.

I read the comment as saying that Waymo's product itself is not living up to expectations.

It looks like it's slowly but steadily expanding, at least in sunnier climes, and offering a decent user experience.
First of all, should be (2023).

Second, he starts with sudo. Where's that command line coming from? Who installed the OS? Who maintains it? What about availability zones and fast failover?

You can do self hosting if you want, but it's not as easy or as cheap as he's making it out to be.

Cloud is still better for early stage startups, that's why everyone's using it.
Also a lot of startups right now need 1 - N GPUs on demand. I do not think the author has ever worked on a growing product.
For example, if the screw/servo controlling one axis of the dish is turned by a minimum adjustment, how many hundreds or thousands of miles does it throw the cone’s target at the distance of the probe? What’s the remaining margin for error at these scales?
20% less plastic, leading to a claimed 13.5 million pounds of plastic annually prevented from joining landfills, is not nearly enough. A sea change is required, so that zero plastic is used for non-essential products (whatever we decide those are, starting with medical, I guess?).
Who will be in line for jail sentences if it comes to that?
If we assume induction motors get replaced by ECM motors or 3 phase induction motors with VFDs, then everything but aquarium pumps and hair clippers? /me ducks.
This is a great idea! Next time I mark a stack of exams I will also note the time of day that the mark was entered. I can then cross-reference this with how long I have been sitting between breaks, since my last meal, etc, etc. Unfortunately I will not have this opportunity until mid-fall 2024.

Oh wow, I'd forgotten about Front Row... presumably named after how if you say with a Mac in the front row of an auditorium the people behind you could pull out any Apple remote and use it to make your laptop fade to black and enter some crazy UI you didn't recognize ;P.

The ages of the patriarchs are almost certainly some sort of Hebraic numerology that has been lost to history and may have been influenced by different traditions (the ages in the Septuagint differ, for example). After all, the fact the majority of them are divisible by 5 is an interesting data point (compared to the lengths of rulership of kings, much later, which appear randomly distributed).

Lloyd Bailey wrote an interesting (non-peer reviewed) paper on the subject, "Biblical Math as Heilsgeschichte?"[1] and Ben Stanhope in "(Mis)Interpreting Genesis"[2] covers it as well.

Democracy baby! /s
yes, or more than one. but doesn't that say more about the metric than about what is measured?
The best answer to that question that I know of can be found in chapter 7 of David Deutsch's book, "The Fabric of Reality." But he's just channeling Karl Popper if you want to go straight to the source. The TL;DR is that science does not rely on induction at all.
> It is just an abuse of science.

> > Our governments have done awful things in the name of science, including eugenics and forcible sterilizations.

"...in the name of science" -- it hardly matters whether it's proper science or anti-/un-scientific nonsense when the result is deeply immoral. The fact is that both science and "science" have been and continue to be used to justify horrible acts. We have to stop that.
I spend quite a bit on cloud, and despite that I would not spend my time setting up my servers/firewalls /auth .. Just not worth the time.

This reads like promotional literature for using Cloud services. Why do all this crap when you can just use AWS or GCP? Heck, as a bonus, you can blame them when it breaks instead of getting fired!
Saw how comfortable and respectful unionized jobs are when my wife had a medical condition. At my tech company, they'll try to create fake narratives to PIP you out.

Unions are totally worth it when there is abuse of power.
I'm a near last letter surname. It's not uncommon for arbitrary things to be sorted by name, but a ton of official things use surname ordering. There's things that also I tend to seem to be last on where I don't know the sorting method, but I suspect it isn't uncommon for someone to just throw in a sort somewhere (though it's also common to see people do things in a LIFO so disadvantage people who get shit done on time... My apartment renewal does that...). I also remember getting a PCR test in covid where they binned by last name.

I can just say I do remember being last in a lot of arbitrary and official things and seeing other friends just get done with it faster and have to waste less time sitting and waiting.

> Introducing a slight bias factor that is randomized each time results in a lower average bias compared to a bias factor that is the same every time.

That's what I'm saying—it's reasonable to believe that the submission time is correlated with other factors, such as ability or confidence (though the effect can cut both ways, with extremely able students submitting early because they finish early or late because they are extra careful, and similarly for other factors). Thus, this isn't really randomization, just correlation with another factor than the name.
Part of it seem to be in the format of the "stop doing math" meme[1], so I am not sure how much of it is serious.

It's actually getting popular again even among quantum physicists.
Anecdotally, I have not come across any German, Austrian, or Swiss CEO who liked unions.
you might be making a case that you can't talk about morality without talking about free will.

I run a sales dev agency and your numbers are decent. Here are two things to try:

- message founders in the space with "I'm working on a new startup and could use your advice"

- after each interview ask them for a referral to someone who you could interview

This creates a referral flywheel and eventually will be a function that brings you customers. I have written a blog post on the topic but I don't think linking here is cool.

Existing inverters are already capable of 150% for short bursts, if you define 100% to be the constant full load capacity.
I don't understand. It's true that judging humans by human intelligence should have a perfect alignment. But it's not necessarily true that judging other creatures' actions by drawing rough analogies to human intelligence is valid. Birds waiting for an opportunity to steal seeds doesn't really strike me as a universal indicator of intelligence.
AMD did not have useful implementation of PDEP/PEXT instructions until Zen 3, which is barely more than 3 years old. All prior AMD implementations were microcoded for compatibility purposes only. If you cared about performance it was faster to do it in software for most applications. The Zen 2 implementation was something like 6-7x slower than the original Haswell implementation.

For all practical purposes, you had to write performance code like AMD did not support PDEP/PEXT.
I could write a novel in response to this.

Top comment reflects on how "getting to market fast" is the most important thing, much more important than costs.

I agree.

Second comment reflects on reliability. Reliability is only a concern when you actually have a product that people want to use.

Cold hard truth:

If you are trying to get to market as fast as possible, most of the cloud abstractions are going to slow you down in most situations. It can be worth it, but your MVP should be as fast to develop as possible and there's nothing faster than writing code and running it.

Second, the reliability of a single machine is much more than you think. Until recently AWS didn't even cover their own reliability of a single instance, if they needed to boot you off a node and shut down your EC2 instance: you might get a bit of notice.

Ironically, you don't even need five-nines in most cases, and if you do, cloud only gives you a toolbox to get there, it's not going to get you there without serious human investment.

You will get 2-3 nines of availability with a bog standard PHP+MYSQL on a single machine.

You know how I know? Because we all did this 15 years ago and truthfully: servers and operating systems are significantly more robust now than they were then, so it's only gotten better for those who do things "wrong".
Surgeons don't get immediate feedback because the advisability of procedure X ends up being a statistical matter that might not be decided in the surgeon's lifetime. It depends what it is. They will have opinions of course, but will work with the system and follow process.
The name "Anki Donkey" leaves you open to legal action from Anki for reusing their trademark on a similar product. I'd recommend changing the name to drop "Anki".
There was a bit of press a few years back when they got approval in Germany, but I’d imagine that Mercedes might be reluctant to bet the farm on this or link it to their public image; self driving cars have not, ah, exactly been an unqualified success thus far, and raising expectations could come back to bite them later.
> The cars aren't autonomous at all

Isn’t this just a swing of the pendulum to a similarly misleading extreme?

Somewhere between “this car is autonomous” and “not autonomous at all” lies the truth of the matter.

These cars have the capability of driving autonomously under specific conditions. If you drive a lot under those conditions, this functionality may be compelling.

Comparing this to cruise control (the automatic variety of which has been available for many years at this point) also seems quite misleading.
