What I find wild is the presumption that with a prompt as simple as “I want to wash my car. My car is 50m away. Should I walk or drive?”, everyone here seems to assume “washing your car” means “taking your car to the car wash”, while what I pictured was “my car is in the driveway, 50m away from me, next to a water hose”, in which case I 100% need to drive.
I think it's a bit disingenuous to reduce the article to a single sentence that's in parenthesis and links to a widely shared publication about an a MIT report. Especially when said article continues with "Don’t get me wrong: I am not denying the extraordinary potential of AI to change aspects of our world, nor that savvy entrepreneurs, companies and investors will win very big. It will — and they will."
One doesn't have to agree with the original report, but one can't in good faith deny that the whole thing smells of a financial scheme with circular contracts, massive investments for an industry that's currently losing money by the billion and unclear financial upside for most other companies out there.
I'm not saying AI is useless or that it will never be useful, I'm just saying that there are some legitimate reasons to worry about the amounts of money that are being poured into it and its potential impact on the economy at large. I believe the article is simply taking a similart stance
The idea seems very cool.
I didn't create an account because it's asking for my email address when using my google account. Don't want more spam.
Also, some decisions seem more politically charged than necessary, like using "Donal Trump" as an example of an "Easy" debate opponent.
Finally, I don't know the SMS-style abbreviations are much appreciated on HN (u for you is the most annoying example in your introduction). I'm not sure why it's bothering me enough to tell you about it...
Some could argue that the transistor wasn’t an invention but a discovery: the physical behavior of the semiconductors has existed for millennia, and we discovered that behavior, but we had already invented vacuum tubes before which did the same thing, just a lot less efficiently. Notice that I said “invented” vacuum tubes because the behavior comes from careful engineering and manufacture which didn’t exist in the known universe before that.
But here too, arguing on invention vs discover is pointless because there’s no common truth…
I'm not sure if the linked pages was updated recently, if I'm completely misreading it or if you're trolling. There's only one processor family (matisse) that's documented as "no fix planned). All datacenter products already have a fix published, and all non-matisse chips will have a new firmware available by october 2024
I’m going to rebound on that and explain why it doesn’t make sense to hold on to RSUs.
Disclaimer: I’m an IC myself.
I worked for my 1st company for 15 years. Held to their RSUs most of the time. Then moved to another (public) company and stayed there for a year before leaving. Now in a startup with a lower salary and no immediate liquidity on my stock options.
When you work at a public company, you have multiple exposures to the company’s growth: the RSUs that have already vested, the RSUs that haven’t vested yet and through your own career growth and salary increase that goes with a successful company. If you were early enough, you also get market cred for having made the company successful. If the companies goes under (or shrinks, or lays people off), all those assets are at risk.
Usually, one has more in granted stocks than in vested stocks. If your company just went public, you might have a lote more sellable than in your pipeline, but even that is unusual. Usually, you’ll still have more in the pipeline than you’ve already vested.
If your company has been public for a while, you should get frequent refreshes, which means you still have a significant numbers of unvested shares.
Regardless, you should sell as soon as you can, because of the remaining exposure through unvested equity. Use the proceeds to place in an ETF, or in a high-yield savings account, or some more aggressive investment strategy. Or use it for the downpayment on your house, or fund your kid’s college funds, whatever floats your boat.
Anyways, keep in mind that you still have a significant exposure to the growth of the company through your unvested equities. If you’re worried about short-term cap gain, don’t be. If you sell immediately, there’s no growth between cost basis and selling price, so no cap gain. Another upside to selling is that you’re not bound by the blackout periods, so your assets are much more liquid. And remember you still have exposure
I’ll play with you:
It might not be such a bad thing to increase cost of trans-oceanic transportation. Right now we’re shipping stuff that makes little sense no to produce locally simply because (cost of overseas labor + cost of transportation) < (cost of domestic labor). I would suggest this is absurd both from an ecological and from a humane standpoint. Increasing the cost of transoceanic shipping might help flip the scales a little bit
Alternatively, I’d suggest that the premiums might not increase that much. Cost of insurance would be (cost of a claimable event)*(probability of such event). I’d hope the latter tends towards zero, significantly reducing the product of the 2.
We can also look at the potential impact of such a “new” policy on total insurance costs. Apparently, the Dali is able to transport 10k containers. And current shipping prices of $4,000 per container, that means that the cost of the trip alone is in the $40M range. If we take the lowest possible value of the goods, that’d be $40M and the arrival location. I’d argue that the probability of losing the vessel and its cargo is higher than that of hitting a bridge, especially if ports start deploying tugboats around their facilities
When B wakes up the 1st thing it does is state.exchange(sleeper,…), which returns unlocked, and set the state to sleeper. I think it works.
I had some concerns about the second one, but I think it works too…
Really nothing disingenuous here. “Trusted by top companies with learning budget” is pretty damn clear and accurate. All in the same font, so there’s no “fine print” argument to be had either.
seeing as some people have already added some comments criticizing the code of conduct, I thought I'd add what I think is the most important parts of that code of Ethics :
No one is required to follow The Rule [...] or even think that [it] is a good idea. [...] anyone is free to dispute or ignore that idea [...]
This is a one-way promise [...]. the developers are saying "we will treat you this way regardless of how you treat us"
No one is forcing their beliefs onto anyone. keep the pitchforks in the shed.
Who cares about screen refresh rate? It’s not a FPS, if’s a webservice for bookmarking. If they can stay under 100ms, everyone would be fine. 16ms is starting to flirt with the limitations of your eye, without even taking into account info processing
translation of the main points (of the linked article, not the full 43-pages BEA-RI report) :
Fire started simultaneously in a battery and and in a power inverter. It doesn't look like there's any comment on why/how it started on either and how/why it started on both at the same time.
Batteries were lead-acid, not Lithium-Ion (lead-acid is supposed to be less of a fire-hazard).
There's timestamped video of the start of the fire. Alarm was triggered within less than a minute. Someone was at the initial fire location within 2 minutes. Building was evacuated within 4 minutes. Fire Department called within 7 minutes of fire start. On site 17 minutes later. Power company is called within 17 minutes of the 1st fire alarm. Power company couldn't cut power from the substation because of fire risk (and delay to get approval from OVH, which owned the substation). The upstream substation is shut down 80minutes after the fire started.
The fire-engulfed building still has power for another 98 minutes. Fire is considered under control 3h after that (6h after it started), extinguished another 3h later.
There was significant concern that the building would collapse.
There was no fire sprinklers or fire-extinguishing mechanism in the building itself. Water supply was insufficient (single fire hydrant delivering 16k gallons/h). Now water reserve, or pumping mechanism (the Rhein was super close).
Only after 2h were the firefighter able to throw water at the blaze. Before that, there was still electrical power on site.
Recommendations:
Battery storage already have some regulation WRT fire hazard. Charging equipment don't. Apply the same rules for both
improve the ability to cut power from a site
There's a bunch of question that pop in my mind :
Concerning the construction, how common is it to have a 1-h fire resistance ? In the report, they say the floors are made out of wood with a treatment to allow for 1h firewall, and the "internal structure" has a 1h "fire stability". That sounds awfully low to me, especially considering that the fire took 6h to control, 10h to clear.
What's "R-5" concrete structure ?
The power is provided through 2 redundant 20kV AC lines. Then, the power can follow one of 3 path :
directly fed into the hardware if it's "clean" enough
corrected to be cleaner before being fed into the hardware.
converted to DC before being fed into the batteries.
My question : Why don't we convert all the power to DC in a central location before feeding DC power to the servers ? I would expect some significant saving costs in DC->AC conversion, no need for AC "cleaning", and the ability to extract the AC->DC conversion out of the servers (increasing density, and removing some more heat close to the servers). I'm sure it's not a new "idea", I'm just curious as to why it's not a good one.
On the report itself, it looks like the presence of battery makes electrical cutoff much harder. If you cut the main power lines, the batteries and power generators take over, so your DC is still powered.
I’m totally happy using the properties format from java. There’s comments, it’s easy to grep. Main missing part are value types and multiline (or maybe it’s there, I’m not sure). The parameter reference substitution would be nice to have too.
no only paying the warehouse, but also you'll soon be on the hook to pay for part A, B, C and E even though you have no way to sell the widget you were supposed to build with them. And if you're really lucky, those stored parts might be either perishable or quickly deprecating due to technological changes.
Here, take my upvote. Can’t remember the last time someone seemed to genuinely apologize, explain what act they’re apologizing for, acknowledges their knowledge gaps and seems to actually thank their corrector, all the while sprinkling the comment with a hint of self-deprecation…
The beginning of your post did sound like a lot of bragging. Once I got to the end, I felt that I could have written a large part of it...
Feeling of being rarely challenged, loneliness, frustration with slowness, and urge to go and fix "it" have been very present for me over the past 2-3 years. It's been pretty harmful to my mental health. But it's also forced me to look at the bigger picture. So while I feel like I've lost a few years of my career, it's not all lost.
Some things I would suggest :
Don't express your frustration. You care, that's a good thing ! But you can't let the frustration overshadow your knowledge and your message. Seen it in some uber-smart people, and it just makes everyone feel bad.
Act as a teacher? I'm not sure if that's something that interests you, but it's something that'll take some of your time, improve the team around you, make you feel less lonely and make you seem more approachable for everyone. I also find it very rewarding.
Change jobs ? New team, new company, new role ?
If you're interested by CS in general, find people outside of work in the industry that you think are "10x" devs as well (god, I hate that term...)? Simply people you respect that have similar interest. I haven't solved the "how" myself, so if you're open to having some off-HN conversations about this, just let me know and we'll figure something out :)
Being from Paris and living in The bay area, a lot more women breastfeed here than in France. Even in the countryside of France, where my extended family is, few women breastfeed.
Please let’s not make blanket statements about Europe vs USA.
Clearly, European countries will be touchy about exporting baby formula. Also, the food regulation being widely different, I’m not sure how easily one could import european baby formula
I just don’t understand the answer. Seems to be conflating “energy cost” and “financial cost” under the same umbrella. I don’t think Prometheus is disputing the energy costs of “the physics required to assemble a molecule”.
Current processes use heat+pressure, which are pretty wasteful, and often rely on burning fossil fuels in the 1st place, which will mechanically increase the financial cost”
What I understand from Prometheus is that they have a different way to “assemble molecules”, which relies on “electrocatalysts” instead of “catalysts requiring high temperature and pressure”. On the face of it, I can totally see how such a catalyst would decrease the “financial cost” without necessarily impacting the “energy cost”. It’s simply using a cheaper energy than the current processes.
The twitter answer rings similar to someone who would say “There is no shortcuts around the physics of producing light” to justify why LED lightbulbs would never make it. Most of the energy of incandescent bulbs is just heat, and there are physical process that produce light without all that heat. I don’t see any reasons why the extra heat would be needed to produce fuels
As others have said, you seem to be focused on the deep technical aspect of your projects, with no clear customer or market.
What is the driving force behind your attempts to start a software business ? IMO, that is the most important question that you need to answer before thinking of "what now". I'm not clear if you want to be your own boss, if you want fame and glory, if you want to be filthy rich or any other reasons. None of them are worth feeling bad about, really, but it's important that you're honest about it. Only then will you be able to forge a path that fits that goal.
The word « apathy » is a pretty important one, and that’s what they responded to. Depression is not necessarily accompanied with suicidal thoughts and dark feelings. For many depressed people, « apathy » is a pretty accurate description. So maybe that person is not clinically depressed, but the advice of mentioning the apathy to the OP’s PCP STILL STANDS, and the possibility of OP exhibiting signs of depression does too
Is really 99% accuracy good enough. A 1gHz computer does 10^9 operations each seconds, 10^7 of which would be inaccurate. That sounds like a pretty high number to me, but I’m no quantum scientist
Honest question : as a GoF researcher, wouldn’t I generate thousands (millions) of mutations from my 1st virus pool, which would each have a low number of mutation (s or n) compared to the original strain, then “select” the most resistant ones from that 1st pool of mutants, and use those to repeat the process ? I’d expect the result to be much richer in n mutation than in silent ones, just because I forced their selection. Am I missing something?
Maybe you didn’t fit the addiction part of aloholism, but when it comes to consumption, a 6-pack a day definitely puts you in that category, along with associated psysical and psychological risks. I’d definitely mention that level of alcohol consumption to my GP and get all relevant blood tests
I think the parent was talking about themselves being a "paid consultant", not the OP
Even for stuff as simple as handling LOBs, I buffer on both read and writes. Some DB APIs really do “what you tell them to”, even if that means being unbearably slow when unbuffered
The worst I’ve seen was actually streaming the LOB on getLength. Since there’s no JDBC API for lob.getContentAsArray(), you need to call lob.getContent(1, lob.length()) (notice that you’d start at index 1…), which by default would stream the LOB twice under the scene!
WTF? Care to explain, or just trolling for fun ?
This. « Demo vehicle » printed on the top right corner of the screenshotted page, 1500 miles on the odometer. Nothing to see here, except « read the not-fine prints »
This was probably career ending at your company, I expect you have been added to a layoff shortlist somewhere for the next round of downsizing.
Uh? I think it’s pretty random to say that kind of stuff without knowing anything about the new company. I can’t see any decent company firing newly acquired employees because they want to move fast…
You didn’t move the IF. you literally removed it.
If (a) DoExpensiveStuff());
Becomes
When modifyA() RecompileIfWithNewAValue();
As long as you call the initial if more often than you modify (a), you’re fine (and the JVM was able to see that you called your if 10k times without modifying the value of (a) even once)
