It doesn't matter that the routers respond to ICMP, it matters that they generate them, and that they're addressed properly, and that intermediate routers don't drop them.

Some routers will generate the ICMPs, but are rate limited, and the underlying poor configuration means that the rate limits are hit continously and most connections are effectively in a path mtu blackhole.
You should start with Unity, it is going to provide you with some rails so you don't go off course and there is plenty of content out there to learn from. Game development is going to be more code than configuration so you are going to have to get comfortable with that.

One thing I have learned as a sysadmin who has had the privledge to see the inside of hundreds of companies from medium sized law firms to F500 oil companies:

There is a lot more incompetence than you would ever want to believe, and it's not always where you think. I've traced most of it to a failure of connection/communication between IT departments and C-levels/boards. The CTO/CIO and the person immediately below them (and the person immediately below them) are the "buck stops here" people for these kinds of issues, but often are either one of two types. 1) Too much MBA, not enough tech. 2) Too much tech, not enough MBA.

Both tend to have pretty similar results.

Answered my own question:

Information Technology (IT): “The entire spectrum of technologies for information processing, including software, hardware, communications technologies and related services. In general, IT does not include embedded technologies that do not generate data for enterprise use.”

Operational Technology (OT): “Is hardware and software that detects or causes a change through the direct monitoring and/or control of physical devices, processes and events in the enterprise.”

So basically OT is IoT and embedded devices, and IT is everything else on your network.
I have got an intern at AWS so I hope I get to see some good design and meet intelligent people there.
It may be speculation, but I honestly can't categorically state it is unfounded. I have no love for FB, and, as parent memtioned, they are hardly the only beneficiary of this particular loophole.

Then, if you recall FB recent stance on e2e, Barr's and Lindsay's comments, the question of political influence over IRS becomes much less an unlikely proposition.

It does not make it automatically true, but let us not pretend that IRS moves in mysterious ways.

To claim otherwise is to ignore context in which IRS goes after them. It may be completely unrelated, but it does raise questions.

I think this is a neat idea, but I suspect it would be more useful as a standalone device than as a wearable. Devices like this could be installed in secure rooms or deployed on the fly in discreet locations with a high rate of success, I'd guess. Arrays of them could work together for better coverage.

Still, this may be the only real option in public spaces (i.e. outdoors). If you're okay with people knowing that you're trying to avoid being recorded, then this would probably be fine.
They still have nearly 10k employees and are a big, affluent company. None of their project should be a one-man project, but, even if it were, they should still be able to find enough engineers to work on it in case of emergencies.

If it can be done by a small startup with a total of 3 devs in the entire company (and I have seen it done), it can be done by a company the size of Citrix.

Property is not a positive right. Property ownership is derived from the self-ownership of the person who created the property by combining their own labor with unowned land. The exclusive right to decide how the property is consumed is a negative right; others have no obligation to provide anything to the property owner, only to leave the owner (including their property) alone. Homesteading imposes no cost on others for the simple reason that these others have no claim to the unowned land being homesteaded.

Your error is starting from the assumption that land is owned in common by everyone, rather than unowned. If land were actually owned in common then you would need to obtain permission from every single person on the planet before using any of it. You would starve to death long before you obtained even a small fraction of the necessary consent. And no, the government cannot grant that consent on behalf of others who never deliberately and voluntarily agreed to permit the government to represent them. You would need the consent of each and every individual.
A crude way to estimate embodied energy is just from the cost. It had to take less than $1.25 worth of energy to produce and distribute. That might have been something cheap and polluting like heat from coal, but it's still not much. You could look up the cost of that in India or China or wherever it's cheapest to get the worst case amount of energy or CO2 emissions.

Alternatively, plastic takes about 100 kJ/g to produce. So if the bulb has 1 g of plastic, that's about 0.03 kWh of energy. Nothing compared to the savings in electricity using it.
> That perspective being, "How fast are you at good enough?"

That's a great question to ask.

However, I now ask you if that's really the question you are indeed asking an engineer who already has a full time job with possibly a hour or longer commute and is attacking your problem at the end of the day or week.

If that's the case, what you are really asking the question "How fast are you at good enough when you are extremely tired and nearly exhausted?"

Either that or you're selecting for candidates who are not challenged enough at work and work at a place that does not fill the rest of their employee's time with busy work to make up for the slack so they have time left over to work on your project.

You have thought of the problem from your viewpoint as an employer but have you viewed it from the viewpoint of an employee who's so frustrated with their current employer that they are willing to put up with hours of looking for job posts, doing background research on companies, filling out forms, following up on applications, answering random trivia questions and random take home assignments at the end of their full work day?
Thanks! That's good to know. Regardless, for this occurrence it was probably better for me to edit and be a bit more specific :)

Agreed, of course there isn't a "right" way. But companies should be internally consistent in how they do these things.

So, I can imagine if you (as the IRS) can demonstrate that they used on method of doing this sort of thing for some stakeholders, but another for the sale to Irish subsidiary with no real justification ... you might just have an argument this was for tax avoidance purposes.

Also I didn't mean to suggest that absolute value comparison was the right way to do this. Just that it is entirely plausible the FB intentionally lowballed the sale. It's clearly the reason these companies are in Ireland at all. Cases like this I suppose are about defining the line between "fair play" and not.

It's pretty amazing how powerful small chip-on-board (COB) LED modules have become. I recently built a 6000 Lumen aquarium light with 7W - 850 Lumen COB modules. The active surface is just 5x5 mm, so the illuminance when held in front of your eye (1 cm² surface) is about 17.000.000 Lux, roughly 100 times brighter than direct sunlight on a summer's day at noon (so don't do it as it might be the last thing your see with that eye). And those modules are actually at the low end of the available power, you can get up to 35 W packaged into such a tiny COB, which is just crazy. Good thermal anchoring of the chips is therefore paramount, as they will quickly heat up to the point of being destroyed by electromigration if they're not properly cooled (and I imagine for the control electronics in the light bulb the high temperatures are also not beneficial). Anyway, it's still impressive how much light you can get out of such such tiny devices.
That is a cool trick, but in that case the energy gradient is from inside to outside the sheet (sunlight heats the air under the sheet), right?

I'm sure the researchers have thought of this, but it wasn't in the abstract.
Thanks! I knew about this book before but couldn’t go through it a lot because it started to get very tough. So, I decided to read each and every concept from the basics before I jumped into that book again.

During cold winter months, when one is otherwise attempting to add heat to the indoors, the 'waste' heat from incandescent bulbs is not really 'wasted', since it contributes slightly to maintaining the interior room temperature.
This is a good find! Thanks!
"As it turns out, that is probably the most popular use case for maps in the world."

...

"I'm confused by the complaint that the "Maps" app only caters to the 90-percentile use case for maps, but doesn't cover the other uses-cases well."

Seems like there is an awful lot of room between "probably the most popular use case" and "90-percentile use case", no?

Smart way to do it, but it will set you back $0.5/month. You can likely do it cheaper with Lambda and API Gateway, but you'll have to invent the secret sauce yourself.

I'm always a little surprised when there are short comings in IAM like that with route53 and records. It seems like a natural thing to be able to control, but for some reason you don't have resource level controls on hosted zones. It's all or nothing.
> I think by implying that the IRS went after them, the "weird trick" was not as legal as previously anticipated, despite being guidance from a professional.

That's about as legitimate as "the police investigated them, so they must have done something wrong". That kind of argument has huge problems.
And? the workers are the ones producing the platform, not the CEO or board members. It's well within their purview to inject politics if they communally agree upon it.

I see the modern environmental movement as a continuation of western imperialism. The developed Western world especially Europe intensively developed their land and eradicated much of their wildlife, in the process of developing the richest civilization in the world. As a result, now the majority of undeveloped land and species lies in the developing world. The modern environmental movement seeks to limit how these countries can develop and what they can do with the natural resources of their countries by using Western social, diplomatic, and economic pressure on these developing countries.
I have started to use Zotero for managing bookmarks. It works quite well - maybe even very well. Also, I can back up to .csv (among other formats) and always have my links. Only downside is to remember to have Zotero up and running - it's similar to needing a local server in that respect.

I (unlike most, I think) still today don't keep a lot of apps open. This is less about performance, and more some irrational OCD sense of comfort.

And it doesn't improve performance.

I actually think the one thing that has improved performance-wise is concurrency. Our computers can now do many more things at once than before. But all of those things are slower, regardless of whether you're doing 50 or just 1.

To many people, computers are a tool;to many IT people, they are a way of life. Its not about big picture, its about proximity- some rant about some minor detail on something you value captures more attention than something you don't care about.

> Cheetah's were evolved to be really fast, but they're still slower than a motorcycle

A good kick can permanently disable a motorcycle such that it can no longer move faster than a cheetah. Less so for cheetahs- they can heal from wounds. A cheetah is also carrying with it all the needed equipment to turn many forms of raw matter (meat) into fuel to power a cheetah. And many cheetahs carry with them a fully functional cheetah factory.

My point is that humans are great at optimizing one dimension, but to build something that is better optimized in enough dimensions to outdo life is very unlikely.
True, and I agree it is bad. But I stand by my original comment. I believe all this happens far more often than we know right now. I predict we'll be finding out in the not so distant future that we've all been targeted and breached. All our data are belong to them.

People rarely apply for Django jobs if all they know and have been working with is Java and have never coded a Django app.

> Sending a jumbo frame down a line that has hardware that doesn’t support jumbo frames somewhere along the way does not mean the packet gets dropped

Almost all IP packets on the internet at large have the 'do not fragment' flag set. IP defragmentation performance ranges from pretty bad to an easy DDoS vector, so a lot of high traffic hosts drop fragments without processing them.

If we had truncation (with a flag) instead of fragmentation, that might have been usable, because the endpoints could determine in-band the max size datagram and communicate it and use that; but that's not what we have.

50% placement doesn't seem bad to me at all...
I related a story recently about a casual friend who decided to mess with me by using email spam. Instead of learning to do loops in csh, he wrote a recursive variant a lot like what you have here. He had to go to the admin to get back into his account.

My favorite bit was he showed me the code, I saw the problem and rather than telling him how to flood my mailbox properly (because really, who would?) I just said, "You don't want to do that..." and walked away.
Yes, the ratholeing vs. generalizing is an interesting phenomenon. I get the sense that it's largely personality-based. Some people (most computer people) are wired up to get every detail exactly correct and if anything is out of place they break out the tweezers and start tweaking. That's exactly what's required in most engineering work. It can lead to perfecting something that's about to get thrown away.

The other personality deals with abstractions, analogies and top-down thinking. When faced with an issue they'll start by defining goals and values. And it's easy to be blind to the details when you're thinking of the big picture and ask for things counter to the laws of physics.

Even if you're a two-minded kind of person and can deal with both generalities and specifics, it's incredibly hard to deal with both at once and quite a task to switch from the one mindset to the other.
Ah, that is interesting. My experiences were before 2018 and I had not kept an eye on it, so I did not know this.
Ask HN: best communication practices at great companies?
I work at a startup where people aren't very good at sharing information with other teams. This creates trust and communication barriers, reduced transparency, unclear roadmaps etc. What best communication practices did you take from working at other companies? E.g. how you collect and share team updates, through which channels, how often, to what audience. What problems it solves?
I've tried a few of the GE bulbs over the years, and the quality and CRI is always not that great (sometimes easy to tell by taking photos with a good camera and seeing how little color you can get out of certain channels). Cree bulbs have always been pretty good, and Phillips bulbs have been the best.

There are a few other brands you can get online that have better rendering (CRI), and are more accurate to the stated color temperature over time, but they cost sometimes double what even the Philips bulbs cost.

I also wanted to add a data point that I've switched every light in our house to LEDs over the past decade, and only had two bulbs (out of maybe 50+) fail in that time—both were in outdoor fixtures which range from 10-100% humidity, and -10°F to 110°F through the year (quite a torture test).
Donald Trump 'offered Julian Assange a pardon if he denied Russia link to hack'
I have some spots in my house where it's a major hassle to change the bulbs, so the long lifetime of LEDs was an important selling point there (in fact, much more important than the energy savings). Thankfully I've had good luck with those (all Cree bulbs), but I'd be pretty annoyed if I bought LEDs for those fixtures and ended up having to replace them after a year or two.
I'm pretty sure that even a 50% mitigation is still valuable, and a remarkable number of attacks are completely unsophisticated. Having gone over server logs specifically looking at this sort of thing, I can tell you that a lot of attacks absolutely do appear to originate in countries that are vanishingly unlikely to have legitimate interest in the site (this was a small local business in the US, with logs showing a lot of `/wp-admin`-type attempts from Asia/Russia). So yes, blindly banning unexpected countries is very likely to reduce the number of attacks that you get, and if nothing else reduce log spam. It's a bit like changing your SSH port: easy to bypass, but it still reduces attacks by quite a bit.
