I’ve heard rumblings from inside AWS that there is internal pressure not to make CloudWatch too powerful, lest it harm their partners (like Datadog, etc).

I’ve heard this a couple times after complaining to AWS engineers about CloudWatch shortcomings.

That said, CloudWatch has gotten tons better than a few years ago.

Not sure I understand the "large" comment.
Painful to configure.. have you looked at CP-Ansible: https://github.com/confluentinc/cp-ansible

High Latency: Kafka's latency depends on your configuration and infrastructure. It has some of the lowest latency out there when configured correctly.

Curios to know why you find it difficult to look after? It's super stable, and is pretty easy to monitor via JMX.
Seems like you're being intentionally reductive to get a rise out of people. But this argument has been had a million times in the form of --

- All corporate profit is theft!
- Profit not theft because money is our primary means of compensating people for shouldering risk, etc etc etc.

I would nonetheless appreciate a pay raise.
> News to me - I thought that study of non-conventional superconductors relied heavily on effective field theories.

What they meant is that understanding the microscopic degrees of freedom, the electrons and ions in a superconductor, does not require field theory. The plain old particle based Schrodinger equations for N electrons interacting with N ions should be absolutely fine.

The problem is that we can't actually do anything with that description, so things like effective field theories help us distill the important parts away.

> Also, I think this is a bit of a strawman - there's a ton of money and effort going into condensed matter physics right now.

While I agree, and I would love to see more progress in particle physics, I also think that comparing the funding landscape of particle physics to condensed matter physics is a little misleading.

New discoveries and incremental improvements in condensed matter physics benefit the world in direct and tangible ways. The frontiers of particle physics left the regime where it can benefit the world long, long ago. The energies are just too high, there's no reason to believe that anything they discover will actually matter to anyone other than satisfying their intellectual curiosity (or spinoff technologies).

I don't want to sound dismissive of particle physics, because I really do believe in doing physics for its own sake, but honestly a better understanding of particle physics is unlikely to benefit us any more than a great new piece of literature, and the price tag on the next generation collider is just mind-bogglingly high.
Yes, it is an accurate description of Cell. RefCell is best thought of as a single-threaded RwLock.

The Cell type doesn't allow you to get an &mut to the contents because a &mut requires exclusive access to the contents, which requires some sort of locking to do through an aliasing reference.

The Cell type also doesn't allow you to get an & to the contents, because a & requires the target to remain immutable for the duration of the reference.

For Copy types, Cell provides access through set/get, whereas for non-Copy types you can use swap/set.
> If anyone thinks less of you because you simply know five swearwords, it's pretty much their problem.

That's your position. When i'm hiring, there is simply no way i would bring someone on board who didn't know at least ten.
I think we frequently make the assumption that others know what we know unless we have evidence to the contrary.

This is a fair critique, but as sibling commenters pointed out, a well-structured interview is highly repetitive by design, so that every candidate for a particular role gets as close as possible to the same interview experience. When you’ve done dozens or hundreds of these it becomes kind of like mind-reading, you just know what the person is thinking and roughly what they’re going to say and do for the next 45 minutes based on what they do in the first 5. And yes, sometimes, that can get boring.

But your point is valid in the sense that, as an interviewer, I do try to bring energy and interest to each interview, both because it’s what the candidate deserves and it’s better for me too.

And to be clear, most interviews are interesting and enjoyable, even the sessions I’ve done a hundred times. But, just being realistic, neither I nor the candidates are always on our A game, and sometimes the result is a quiet and dull interview.

And to be clear, that may still result in an offer recommendation! Some of these interviews are dry because the candidate knows the material down pat, doesn’t want to chit chat, and has no questions. Those are, in fact, the very kind of person I imagine would improve their performance by smiling and asking what I had for lunch :)
Are you intentionally being simplistic or do you really think that’s a reasonable statement? Are you literally trying to claim that any given life is a fungible economic unit?

According to the NHS, over half of deaths attributed to covid in the UK were going to die within a year anyway, from other causes. Over half of deaths are from nursing homes in many places. We’re sacrificing the economic livelihoods of our children to buy a few months for a small fraction of the sickest, oldest people.
They're charging $400 an hour to come in and unfuck years of devs thinking they can design databases because they read a MySQL How-to Article
Same is with Free Software. On one hand it is nice that you are receiving so much value for free, on the other all business models revolving around it contradict basic sales principles and are wildly unsuccessful.

So for example, I use horrible debuggers like GDB in 2020, because there is no company that is willing to put that much effort and take that much of a risk into developing a better tool debugger, since there are no profit incentives around it. You cannot really expect developers to pay for their tools in 2020 and that is both good and bad.
Years back there was a trend of using blurred profile photos, which could be "unblurred" if some criteria had been met. This is a logical extension of that idea and I wish I'd thought of it back then.

However, I don't like the idea that "women control the blur". While I think I understand the reasoning, I think it would be better to automate the process. For instance, gradually decreasing the blur based on number of interactions, with participants slowly "resolving" and becoming clearer to one another as they get to know one another.

In this way, each person involved "controls the blur" by simply choosing whether or not to interact with the other person again.

And btw what about same-sex interactions where there is no woman or two women?
This is just burden-shifting, and if it is the best argument that can be made, there would be essentially no case for a bigger accelerator at this point.

Things are not quite that bad, but the case is weaker now than it has ever been before.
I assume it censors 'Spurs' to '_____'.
That is because Western Europe has restrictive tariffs on car imports.

If you want to put high tariffs on imports in the IS, then the IS industry would re-emerge also - though the price of cars would double.
What makes it difficult to look after? Genuinely curious. I've run it in production for years and its been pretty solid.
Not a lot really, as far as the 74xx series goes. 10ns gate delay for the original 74xx TTL chips, vs 6ns gate delay for the current CMOS 74HCxx chips. The reduced power consumption is a bigger benefit.
There is the idea that consciousness cannot be expressed as a computational process (at least not a classical one) because computation is deterministic. We are a part of nature and nature seems to be unpredictable at the quantum level. Quantum states can not be predicted even when taking the whole past history of the universe into account.

I think the free will lectures from John Conway also go in that direction: because some properties cannot be predetermined, free will must exist. Something must make a decision in order to have an outcome.

This all goes far over my head and I may have misinterpreted the great John Conway. In that case I beg your pardon and would love to hear your thoughts on it.

I can’t follow his logic whatsoever.

China...actually handled this outbreak. That’s why they can reopen. They were locked down for months in many areas. So that comparison if anything is a justification not to reopen right now - stay locked down long enough to squash this, and we’ll be able to safely reopen like China.

If anything he should be suing the county for putting on such an ineffective lockdown which makes this take longer than it needed to. Businesses are forced to close but for individuals it’s basically a completely voluntary lockdown right now and I see lots of people opting out, not wearing masks, meeting up with friends, etc.
You should be able to (within reason) use your computer without an internet connection.
Moreover comparing a HOSPITAL with a factory is ludicrous as the viral loads are orders of magnitude different.

> The higher the frequency, the steeper the gradient.

Losses also scale with frequency.

And while other acceleration principles have higher voltage gradient, they still can't reach TeV of collision energy, since you either can't concatenate them, or you can't control the beam sufficiently well.

As I wrote in another comment, stuff like plasma wakefield accelerators need to get better by a factor of 1000 before they reach the realms of SRF accelerators. This wont magically happen over night.

And most of these people have tenure, they hardly care for trends.

I have been to all major accelerator physics conferences over nearly the last decade. Despite clic there is no one seriously claiming to go beyond LHC energy without SRF. No one. Not the plasma wakefield guys, not some strange theoretical accelerator principle. No matter what you read on Wikipedia.

Your namedropping comments with very little actual content, disregarding the work of thousands of scientists show a certain arrogance that is super annoying.
How do you monetise your own site?
Do you all have any idea to monetise your own site? I've heard of affiliate marketing but I don't want to sell whatever i do not believe in, or do not really use. Do let me know what are your thoughts?

I also wonder if you all know how I can go about monetising my blog in particular as well? I mainly posts about technology and learnings.

Photoshop was a big one that I missed, until someone posted their self-made online editor to reddit: https://www.photopea.com/

I'm not sure what modern photoshop looks like, but the interface is completely familiar to me as a former CS2 user.

While Photopea is online, its completely satisfactory for small editing tasks that I need to do. Only gripe is that saving massive pngs with 100% quality causes the site to freeze

I lack experience in AWS or clouds but I wonder what is the alternative to CF if I should avoid it? I can imagine alternatives to the rest but I cannot come up with one to CF.
It's not over until those countries' policies are back to how they were prior to the outbreak (borders open, travel allowed, no lockdowns). Until then, it's just hoping for the best for when they do.
Shots fired, haha :)

Just to make sure you see it I’m copying some things I wrote to other replies:

1. Charisma is a plus, but how much depends on the role, and for most roles it’s not going to matter.

2. To be clear, most interviews are interesting and enjoyable, even the sessions I’ve done a hundred times. But, just being realistic, neither I nor the candidates are always on our A game, and sometimes the result is a quiet and dull interview.

Could you elaborate on the proxy pass option piece?
The CDC and/or FEMA having emergency powers during pandemics beyond what might be expected was something of a sci-fi trope for years. I guess there was some kernel of truth to that premise.

Example from the sci-fi game Deus Ex:

> Informed Guard: Executive Order 10990. It lets us take over all modes of transportation.

> New Guard: FEMA can do that?

> Informed Guard: If the President declares an emergency. Executive Order 10995. We can take over the media.

> New Guard: All of it?

> Informed Guard: Any at all. Executive Order 10997. We can take command of natural resources.

> New Guard: So it's all legal.

> Informed Guard: The National Security Act also falls under our umbrella. And the Defense Production Act. If he plays his cards right, Walton Simons can pull off a bloodless coup.
How Pandemics End
“Lives” are not fungible. Covid almost exclusively kills people who were very close to death anyway - look at the age and comorbidity data. It’s very clear. If anything, the numbers are absurdly inflated because people are dying with covid rather than from covid.

It’s abundantly clear that the US’s approach will cause more net long term suffering than Sweden’s approach. It looks like the increase in overdose and suicide deaths among younger people is already on track to destroy way more life-years than the most generous attributions to covid.
honestly im not sure how sarcastically to take this. you can listen to one day of content and really not absorb any of it. it takes the rest of the week to apply, reframe, doublecheck, internalize.
This is completely tangential to the actual content, but what's the aim of a screenshot of Wordpress' PHP as the article lead image? It's on the first page of results if you search "code" on Unsplash and doesn't really add anything to the writeup. Maybe I'm not the target audience, but it'd be much better to read what you have to say rather than scroll a screenful of a stock image first.
I know several people that regularly give out autographs. I've heard from several of them that their autograph is totally different from their actual signature. Only a couple of them said it was for security reasons, where most have said it's just simply to make it as fast as possible.
Aside from being a meaningless anecdote, your claim is unproven. How are we supposed to know that you really had an order?

Also, this comment is pure advocacy. We come here for analysis and depth.
That number has to be put in perspective. There's barely any excess mortality in Germany since COVID hit (meaning it's within normal variation). That's success any way you look at it.
People aren't generally very good at probability. Plenty of people get it wrong despite understanding the puzzle correctly.

> Valve is basically a criminal game stealing empire by infecting games with client-server code.

Uhh.. Valve release all their game server binaries for anyone to run, and sometimes even the source code (Half-Life, Half-Life 2). If you're going to rag on any games company, it shouldn't be them.
I guess I'm not seeing the distinction. People do have nice little side businesses built around blogs, which are pretty easy to set up. (I'd never go the Medium route; I've published there but only as a copy from elsewhere.) And anyone can publish a book on Amazon even if they can't/don't want to go through a traditional publisher.

I just don't see recommendation engines/other infrastructure on YouTube as offering any particularly unique discovery and monetization mechanism vs. other media. If anything, it seems you're more dependent on the whims of Google than in the case of, say, an independent blog.

Godot lets you script with native code (GDNative) and more importantly lets you access the very low level parts of the engine should you so wish, allowing you to implement advanced custom functionality performantly.

I do get your point but honestly unless you're a big studio or a custom engine enthusiast, there's very few logical reasons not to use a framework.

After 4 Years of Silence, a Call to Mom on Mother’s Day
Interestingly I have the opposite experience with the previous battlefield 3. There are still several active servers, all of them are generally fun to play with no weird rule sets. I remember in the earlier years of the game some servers had rules like no sniper and you were automatically kicked if using one but that was made clear in the server title.
The initial claim is broad. ...but the application can be pretty narrow as neighboring jurisdictions are allowing people back to work.
Please consider more critical thinking.

What we know is that certain outlets report that 281,147 deaths in the world were attributed in part due to symptoms potentially related to Covid19.

This is a sad terrible time, but the likelihood that those numbers mean what you think or say they mean is low in my opinion.

The evidence from Sweden and from serological data everywhere doesn’t suggest that to be the case. It’s looking more and more like the lockdowns are actually accomplishing approximately nothing. But I can tell you didn’t consider/understand my point about why it’s stupid to just optimize for “number of deaths”, which is the relevant part.

side note: I did note a change we built made it in to a released version of qemu:

> qemu-img convert -n now understands a --target-is-zero option, which tells it that the target image is completely zero, so it does not need to be zeroed again.

It’s worth mentioning how simple the computer is. While the Gigatron is an 8-bit computer running at ~8 MHz (and probably more powerful than an 8086), it only has... seventeen instructions (with a few encodings for different operands). The instruction set is so limited, they created Gigatron Control Language (GCL) to allow you to write in a slightly higher level assembly.

So getting an emulator running is quite an achievement.
Anecdotes are worthless.

>That's unnecessary, unhelpful, and just escalates the debate immediately.

Stating facts about the fact that everyone is losing control of their PC's because of their stupid consumer behavior is not in any way inflammatory.

Why would you give away your basic rights to own and control your own PC and have it coded honestly unless you were irrational?

There are dire implications for privacy and human rights if you believe in "cloud computing" which I refer to as "stolen software as a service"

SaaS can only exist in a world where the public is irrational, you are building turnkey dictatorship infrastructure, if the world ever goes south because every piece of software can monitor and spy on everything you do and is broadcast to foreign companies and governments, you are naively trusting these foreign entities have your best interests in mind.

I'd say that qualifies the word "stupid" in my post. You've just allowed every big company to spy on you permanently and helped wipe out privacy for the rest by producing perverse market incentives for software that locks down our devices and removes our freedom and privacy.
This. People who swear do it so frequently it looses the power. It shows a lack of vocabulary more than any sort of moral failing. If you only swear rarely you get a lot more impact when you do, vs. the person who cannot avoid every 3rd word being a blue one.
