Ask HN: Why is Java AOT compilation (using graalvm native-image) slow?

I like KDE 5 very much, personally, and am a user of the KDE Neon distro. If you've looked again at KDE recently, what are your primary paint points?
Here is the rationale given in the source paper: https://media4.manhattan-institute.org/sites/default/files/t...
quoting from paper:
Basket Component: One Semester of Public College
Source: The COTI uses the federal National Center for Education Statistics estimate for total tuition, fees, room, and board at a four-year public institution. 67
Rationale: Two children pursuing four-year degrees would require a combined 16 semesters of college, so a household preparing for those costs would need to save roughly one semester’s worth of cost per year before the children reached college age. (While the savings might ideally earn a positive return in the interim, that return would need to be quite strong just to keep pace with the rate of increase in tuition over the same period.)
The one-semester estimate may overstate costs in some respects—for instance, a family would likely have 20 or more years between the birth of a first child and the college graduation of a second. And in practice, many children do not ultimately attend college (though a small and, it seems likely in recent decades, declining share has chosen from a young age not to consider that path). But it also understates costs by considering only public college costs; private college costs are more than twice as high.68 Note also that the cost of public college tuition already incorporates the substantial public subsidy provided by the state government.
It is simple to see what energy source is pulling above its weight and what energy source is pulling below its weight.
Go to here: https://www.eia.gov/beta/electricity/gridmonitor/expanded-vi... , select "daily" view and put in 60 days to get a more representative sample.
on 12/19/2020 -- looks to be a fairly typical Texas winter day
natural gas production was 331660 megawatthours
wind was 191415 megawatthours
for a ratio of 1.73 gas/wind
this appears to be fairly typical numbers on a daily basis over the winter -- actually on a number of days wind surpasses gas
natural gas 692091
for a ratio of 7.68 gas/wind
natural gas 2/16 vs natural gas 12/19 is ratio 2.09
wind 2/16 vs wind 12/19 is ratio 0.47
so as expected during an inclement weather event natural gas ramped up and wind ramped down. natural gas just didn't ramp up enough to pick up all the slack from increased demand and ramped down renewables.
"I get that wind + solar can't cover everything, but right now what we're seeing is massive failures from gas. In a universe where we had more wind + solar, there could likely be more energy going around right now." -- Wind is failing much worse than gas from an objective power generation standpoint. All wind has going for it is the tyranny of low expectations.

Researched each of those models -- none of them are actually available for purchase currently as best I can tell.
I prefer sct -- a very simple tool for setting the color temperature:
I apologize for not making it clear that I intended this to be a parody illustrating the absurdity of a certain POV when carried to its logical extreme (most POVs are incorrect when carried to an extreme).
After further thought, I should have added an /s at the end or better yet not posted at all. My apology for the dishonesty to anyone who took this literally.
I meant this comic to be a somewhat tongue-in-cheek parody of positions I have seen people take, which I intended the ellipses to hint at. Clearly there are some genetic differences between populations.
Race does not exist... therefore there won't be a genetic difference in average outcomes between different people groups. It is useful to think of variation from person-to-person but it is impossible to make comparisons between ethnic groups/races because no substantive differences exist among the various human populations. Probably the study results you reference are a result of different environments...
I feel that Windows 10 has an improved file explorer and file copying dialogs over Windows 7. In every other way I feel that I still prefer Windows 7 -- system stability, lack of apparent bugs, much more coherent settings functionality, lack of resource-consuming microsoft spyware (cortana), better built-in themes, messages from system are less annoying/"cutesy", ability to fully control updates, lighter and better built-in apps.
I think 7 still remains the peak of Windows and I agree with you that Windows 10 presents a lot of motivation to stick with OSS :)
Just a note: turblety's comment does not make any allegations to the effect that you can't /run/ compiled lazarus apps on macs, just that it seems hard to set up a lazarus dev environment on that platform.
So? You did not address the argument or the information presented, but rather went straight to attacking the messenger. Seems to me that the central thesis that renewables are increasing electricity costs even as main-stream journalists report that renewables are now getting cheaper than non-renewables and commonly say things like "we are reaching a point where the new energy technologies are going to be cheap enough to drive a lot of the old coal-burning power plants off the market" is correct -- or at least I haven't seen evidence to the contrary.
I personally think that might depend on what you mean by "slow". Tcl/Tk programs can be very light and memory-efficient -- you can pack a lot of features into a program that only takes 10 megabytes or less at runtime and that starts up and responds to input near-instantly. The event loop abstraction which is well-integrated in Tcl makes it easy to handle sockets, files, timers, and gui events all on one loop which done right can keep your program very responsive without needing to worry about multithreading.
In terms of pure runtime performance (CPU efficiency I guess), do you know of any reasonable benchmarks comparing TCL to say, Python and Ruby? I wonder if they might all be in the same ballpark?
I don't get the joke. The truth is probably that genetics do play a role (perhaps small though) in intelligence, as it does with other measures like height or bone marrow donor compatibility.
I think its a joke, or it should be. Income of $200k puts you above 97.3% of Americans according to https://dqydj.com/income-percentile-calculator/ .
As with most things that can be measured, it depends on your POV and agenda.
In 2017 dollars Regan increased the debt by ~ 4.15 trillion, while Obama increased the debt by ~ 8.88 trillion (using the numbers found at your link (which is just one way of counting the debt for a president), taking the the entire debt increase as a lump payment in the middle of the presidency and using this inflation calculator to estimate the amount forward to the present http://www.in2013dollars.com .
So in absolute terms Obama increased the debt by more than twice as much as Regan who had "insane deficit spending" according to you.
Also you state that Trump is on track to increase the deficit in 4 years more than Obama did in 8 years. I believe this is a lie -- the estimated numbers even on that website show 1.233+1.225+1.193+1.119=4.775 trillion over four years for Trump which is marginally less than Obama spent over his first four years (even excluding the Economic Stimulus Act in 2009) of 0.672+1.276+1.229+1.652=4.829 trillion even before adjusted for inflation. On what planet is 4.8 trillion more than 8.9 trillion?
Your post does not address Raymond's arguments, but instead primarily just attacks the messenger as supposedly not being qualified to comment on language trends.
While it may be true that ESR is not a superstar programmer in the image of a John Carmack or a Bill Gates, he has been a working C developer for over 30 years, and has contributed to numerous open-source projects, including systems projects, over that period of time. The examples he lists in the article are some pieces of software which he is currently a maintainer for.
Actually I think the fact that he is not a superstar programmer with a signature project possibly makes him a bit more qualified to comment on language trends. After all, most of the developers in the industry are by definition about average, and if average (or even somewhat above average) developers are finding their productivity much higher in Python and Go than they do in C, then they will start doing more work in those languages and less in C. In fact, that transition is exactly what ESR is describing in the article.
Certainly it seems that Go is usable for certain classes of problems that would formerly have been C's domain.
Note that it appears that a large number of the segfaults which Michael (phoronix) is reporting may be coming from a software issue. In particular, people on the phoronix forums are reporting that conftest segfaults are a known software issue and also one has reported that he was able to reproduce the conftest segfaults on an intel CPU.
So not saying that there's not a problem with Ryzen, but it is possible a large number of the errors are false positives arising from a known software issue.
I would wait Michael runs the same test on an Intel CPU with no problems to pass judgement.
March 24, 2017 -- "During the past year, Let's Encrypt has issued a total of 15,270 SSL certificates that contained the word 'PayPal' in the domain name or the certificate identity. Of these, approximately 14,766 (96.7%) were issued for domains that hosted phishing sites" 
LetsEncrypt isn't perfect either. You've got to be cognizant of what details you are sharing over the connection, regardless of who signs the certificate.
