In the US I expect prime meat to be considerably cheaper than usual. With restaurants not buying there will be a glut and I expect regular stores (instead of just speciality shops and suppliers) will be getting it for awhile.

If there’s 1 thing the US has it is food and the supply chain is excellent. If anything this is an opportunity for the US to make a move on trade with Britain and possibly the EU to export our Ag there, for awhile anyways.

Given that the US government was prevented from _counting_ them in the 2020 census, I doubt this very much. As an immigrant myself, I also took the liberty of replacing "immigrants" with "illegal aliens" in the quote above, to be more precise.
Having been in this situation, as well, I find that the aging out of technology MUST be led by a CTO who is competent enough to know that tipping point of cost-benefit. Their job immediately becomes a political choice (pass the pain to the next guy) when the point has passed and it gets worse every new CTO. Some of these systems are HUGE (hudreds of millions of lines of ColdFusion, where I worked).

No I’m not. I’m saying FAANG are hiring based on fast pace general problem solving skills that are difficult to game and have very little to do with computer science.

That is why “our” interview processes are being compared to IQ tests.

“We” have rejected people who teach computer science fundamentals at prestigious schools and hired teenagers who only started learning about algorithms a few months before the interview.

How is that relevant at all?

Thank you! Linux desktop is far from secure, even with all these suggested solutions. The lack of popularity by attackers means defenders and coders alike focus on mitigations based on assumptions or a small amount of historical data.

From a bad guy's perspective, they just need a foot in the door and move laterally if possible.

In my opinon, while all these hardening features are great, nothing beats behavioral detection and prevention. This isn't easy on linux to be honest, but a way for admins(power users?) To define rules like "a process tree with firefox as a parent is running unusual commands or processes" , more or less what is done with sysmon except with perhaps the audit subsystem would be of tremendous use. Assuming you can't prevent initial access or exploitation, what can be done to detect attacker activity on Linux Desktop?
This is not actually correct. See this NRC publication "Radioactive Effluents From Nuclear Power Plants: Annual Report 2008."

https://www.nrc.gov/docs/ML1036/ML103620452.pdf

Power reactors discharge a small amount of radioactive material into the environment under normal operating conditions. See figures 4.1 through 4.12 in the report. The Palo Verde Nuclear Generating Station in Arizona [0] released 1844 curies of radionuclides in a year from gaseous, liquid, and particulate discharges. In SI units, that's 6.8 * 10^13 becquerels.

According to the World Nuclear Association, a kilogram of coal ash contains about 2000 becquerels of radioactive material [1]. In 2012, the United States coal fleet generated about 110 million tons of coal ash [2]. In 2012, the United States generated 1514 terawatt hours of electricity from coal [3]. That puts the coal ash radioactive burden to the environment at roughly 1.45 * 10^11 becquerels per TWh of electricity generated in coal plants.

The Palo Verde annual radioactive effluent discharge of 6.8 * 10^13 becquerels from an average of 32.3 TWh electricity generation [0] comes to 21 * 10^ 11 becquerels per TWh of electricity. Its radioactive discharge to the environment is significantly higher than the average discharged via coal ash to produce an equivalent amount of electricity.

However, before getting alarmed, see figure 2.1 in the NRC Radioactive Effluents report that I linked at the beginning of this post. Even though nuclear plant effluent adds more radiation to the environment than coal ash does, industrial sources of radiation (including nuclear plants) account for about 0.1% of general population radiation exposure. Natural background sources add up to about 50%. So the marginal danger of radioactive exposure from normally operating nuclear plants or coal ash dumps is very small.

People who say that coal plants emit more radiation than nuclear plants are not helping to counter "radiophobia." They are in fact attempting to exploit "radiophobia" to stir up fear over a very minor aspect of coal's environmental harms. (And coal really is an environmental disaster in many other ways.) Worse, people making this argument are not even correct about the underlying numbers. Many of them are just parroting a Scientific American article [4] which itself is a misleadingly garbled retelling of an actual research report [5] [6].

Good point. AGPL goes definitely in the direction. It is not just open-source it definitely also has parts of the fair-code spirit...
Yup, and that's kinda intentional. The design is to be a monitoring system, not a generic TSDB. What it does needs to be simple, fast, and reliable so that your alerts get sent out.

The original design inspiration, borgmon, also was a terrible storage system and had an external long-term store layered on top of it.

This isn't a design flaw, it's an intentional trade off to make the core use case as bulletproof as it can be. Having seen "monitoring systems" based on something like Cassandra, aka distributed storage, is cringe inducing. The first thing to crash a the first sign of network trouble is distributed storage.

is it the time to stop kowtowing to the the Chinese government?

the way I see it it is the PRC use their clout to bully individual Nations with the knowledge that other nations will happily take their money so they can threaten to remove this money and find another country to fund. If all Nations start rejecting the PRC worldview on things like calling Taiwan, Taiwan and not so readily accepting the government views they will not be able how to use that influence anymore. this would also reduce their legitimacy at home. now is the time to break trying to strangle hold on manufacturing which is basically what supports there are entire economy and as a result keeps the government in power.

Calling non-D functions means the compiler cannot check them, and will rely on the user having correctly specified and annotated the function signature.

I.e. you can have "unsafe" annotated code which the compiler doesn't check, which is indeed where the dirty deeds get swept. For example, I doubt someone could write a guaranteed safe implementation of malloc().

The idea, naturally, is to specifically mark such sections so that your crack QA team knows what to focus on, and to minimize the amount of such code.

The trick is to make the safe sections expressive enough that it is practical to write the bulk of the code in safe sections, thereby minimizing the "threat surface".

Please be careful in announcing new truths based on your interpretation of a couple papers. That’s not how science is done.
Common.net is planning on gigabit wireless service in Alameda and San Leandro later this year. And they offer 300mbit service now. The technology is there to do this without laying fiber or other traditional infrastructure. If there are many people that want something better than DSL start a wireless ISP.
In fairness, now that I check Wikipedia, it appears that the SPR is 80% full, and furthermore the average price paid was about $28/barrel.

Right now WTI is $25ish and Brent is almost $28, so adding more to it probably isn't particularly vital at this moment, either in terms of increasing energy independence or in taking advantage of cheap prices.
Looks like I'm stupid :)
The tests on the SARS virus used 254nm wavelengths, which deactivated the virus in fifteen minutes. Your sources both say that that length causes severe damage, and both only tested 222nm's ability to kill bacteria. A conclusive "yes" would need testing done on a virus with the 222nm length.

Eventual deprecation is not a valid justification for making current technology less useful.

Now I would buy your argument if C++ were as conservative as C, but it clearly isn’t. It keeps trying to push itself as a modern general purpose language, while ignoring what it actually takes to be useful as one.

Because the DFA follows edges, not logic. If free appears twice along any sequence of edges, the compiler rejects it.
>what is not always talked about in the media currently is, that not all viruses are replicated functional. In fact, a large fraction of viruses produced are not capable of infecting a cell in the first place due to replication errors, mutations, etc.

I agree that people aren't writing news articles about that, but why is it noteworthy that they're not? It doesn't matter if only 1% of the virus particles on a surface are infectious if there are millions of particles.
Thanks for the feedback. Let me fix that.

> they're fundamentally referring to the underlying engine that makes those apps slow. If that engine was fast and light on resources, the complaint wouldn't exist.

Firstly: in that case you'd have to compare it to the weight of the entire desktop environment. I would bet money that Gnome + your GTK app is not meaningfully lighter-weight than Chrome + an Electron app. It's just that the former has a privileged place in the OS, and is a dynamically-linked dependency instead of a statically-linked one (using those terms loosely).

Secondly: The web itself is not fundamentally slow. People who aren't web developers love to repeat this mantra, but it's simply not true. That's what I'm trying to get to the heart of here:

1) JavaScript is slower than C++, but it's very rare that enough actual work is being done in JavaScript for it to become a bottleneck (on the UI side), even in complex web-apps. Most of the grunt-work, including recalculating layout, is implemented in C++ as part of the browser.

2) Layout calculation can be slow-ish in extreme cases, but that's a direct tradeoff for the benefit of using the world's most advanced UI layout system, which provides real value.

3) Under normal circumstances an entire web page runs in a single thread, which can be a problem when the occasional expensive operation blocks other ones, but Electron gives you several options for moving expensive operations to separate threads. By default the web view runs in a separate thread from the "main" process, and you can spin up workers or even split your UI into separate web views so each panel gets its own thread.

I think the origins of this myth are:

1) Websites have become much slower than they need to be with the increase in JavaScript dependencies. 90% of this is due to ads and analytics, which couldn't care less about their impact on page performance. The rest has mostly to do with the initial load-time of that 1-2MB script, rather than the runtime of the actual JS code.

2) As with any technology that lowers the barriers to making things, there's been a dilution of less-skilled developers putting things out into the world, decreasing the overall perceived quality of the space. But this isn't an indictment of the technology; if anything, it's a complement. It has to be distinguished from the actual merits of the tech.

> but by using Chromium everywhere, developers don't have to deal with cross-browser issues

I think it has more to do with being able to build and ship copies for all systems through a single channel. Building a "first-class" Mac app (a dock icon, hooks into system APIs, etc.) that uses Safari's web view right now would probably mean opening XCode and writing quite a bit of actual Swift as a wrapper around the web UI. People don't want to do that; it defeats a lot of the purpose. My proposal in my last comment would solve this problem.

I think that's why you're getting the response you are in this thread - if it really did '100% of the positives with 0% negatives', it'd have to consider the logic. There's an impossibility proof for that which has already been cited in the thread. It's usually illustrated using a function that solves the halting problem rather than the Goldbach conjecture.

If the compiler rejects things that have free appear twice on branching control flow paths but aren't actually broken due to dynamic control flow (like your looping example given elsewhere) then that's a false positive, isn't it?

And people thought '0% negatives' was meaning 'no false positives'.

The US military has authorized the use of hollow point rounds as needed. They just don't believe that it's necessary most of the time in combat. Which is entirely correct - modern FMJ rifle ammo achieves similar and better terminal ballistics via fragmentation, without sacrificing armor penetration or flight ballistics like hollowpoints. But for 9mm, the equation is different - hence why M1153 is a thing, and is issued broadly to military units.
I used to think municipal fiber was the answer to improve internet service, but while it may work, I've seen that it is certainly not the only way.

I moved to Berkeley for university and there are several competing options for gigabit internet (including Sonic, LMI, etc.). When the gigabit service arrived to disrupt the AT&T/Comcast duopoly, suddenly the customer was important, and we were able to get great speeds, prices, and customer service.

What I'm saying is that you don't necessarily need to make internet a public utility to improve service, just to get some real competition. If that competition needs to come in the form of municipal fiber, then that might also work, but it could also be a private company.
Products which require a lot of manual effort to harvest are generally luxury goods, not essential for feeding the population.

If for whatever reason it seems that this year there's not going to be enough migrant labor to harvest your strawberries, then when the spring comes you can plow that field over and plant potatoes, which will require much, much less labor and feed more people from the same field.

This year is very much not 'business as usual' both in production and also in consumption. Just as most other fields, farming needs to adapt to the changing situation; IMHO it's counterproductive to invest a lot of resources to try and preserve the status quo - we're going to see that some farm products become harder to grow, or harder to transport, or are more difficult for people to afford because of economic problems. It does not mean that we should heroically strive to preserve our ability eat as before, if that means that we're going to be eating less of product like that - less fresh food year round (greenhouses or imported), less meat, less fruit, etc, than that should be accepted, and it's okay; and it's okay if the circumstances force the farmers to switch from high-value labor intensive foods back to cheap, efficient staple crops.

A prime example is the scenes I've seen from Netherlands sizeable flower plantations; as flower purchasing in most of their export markets is way down, a lot of the harvest is just discarded. I'm certain that some of that field/greenhouse capacity will be repurposed for basic food growing instead.

The news in France reported strictly the same situation.

Polish Worker ( which are majority in field work in rural area ) are sent home due to quarantaine, thus there is not enough workforce to harvest fruits and vegetables. More than half of the production of small farmer is at risk of being lost , and theirs salary with it.

The Unicode issue is one of the most painful sticking points. Handle legacy filesystems with the chance of filesystems that have previously valid (non / non \0 containing filenames) files in various encoding soup nightmares? Python3 is NOT the the tool for that job!

No. The study I referenced used total energy per cm^2 required to deactivate the flu virus, which is J/cm^2. You get that by multiplying the flux by the exposure time.

So whichever exposure time gets you the 1.8 J/cm^2 is enough to kill the flu virus and presumably SARS-CoV-2.

> I guess that performance is at least as counter intuitive as statistics.

I don't think this is really true. After you've optimized enough code over the years, you start to get a sense for bottlenecks, and your code is usually "fast enough" even on the first try. When it isn't, finding the problem with a profiler is usually pretty straightforward.
