I worked on a different xenon-based experiment[1] for my PhD. We were looking for similar rare decays to learn about neutrinos. Our observation of double beta decay of xenon 136 used to be the record for rarest decay.

Xenon has some very nice properties as a particle detector for rare events:

1. For one thing, it's a noble element, and so it can be purified very well to reduce background decays of other elements.

2. It's also a very heavy atom, and so it's self-shielding from external radiation. The core of the detector is shielded very well from radiation coming from the outside, so any signal you see there is most likely from decays of xenon or from things like dark matter WIMPs that don't interact much with matter.

3. It is a natural scintillator[2]. It gives off light when an interaction or decay ionizes the xenon atoms. That lets you actually detect the event, and by collecting the scintillation light, and the electrons from the ionization, you can get a decent measurement of the energy of the event.

4. It's recyclable. The XENON1T experiment follows the XENON100 experiment. The 100 kg from XENON100 were reused in XENON1T, and the tonne from XENON1T will be reused in future experiments. So the cost gets amortized.

$120/g sounds on the expensive side. The price is always changing based on supply and demand. One manufacturer deciding to use xenon in some process, or finding a way to replace xenon with argon, can swing the price by an order of magnitude.

As for leaks, I can say on our experiment we took the possibility very seriously. The entire xenon gas system was made of ultra-high-vacuum plumbing, and we helium leak checked every connection. When the xenon was outside the experiment in bottles, we had sniffers around the bottles to make sure they weren't leaking. We also had emergency systems in place if we needed to recover the xenon, including a "balloon of last resort" that would've captured the xenon in the event of a catastrophic failure.

I'd rather not mix archaeology with politics. The museum fire was heartbreaking but to call it a conspiracy against our own history is too far fetched.

Don't get me wrong. I despise the current government. I just don't think there's any conspiracy here.
Is that what the arts and humanities graduates serving my coffee in Starbucks are generating - culture?

Don't conflate culture with those who study it. The vast majority of non-STEM graduates generate no activity of either cultural or economic significance. All such degree programmes could be dropped tomorrow with no detriment to society.
> Is it because they also have a web version and people can use the web version also (amounting to content consumed outside the app)

Have a web platform as well, use 3rd party billing dont pay the tax. You sort of know the answer to this question.

You may be looking at the wrong side of this however.

After the cost of setting up a 3rd party gateway, and then dealing with currency (if your international) and then dealing with the overhead of a website or other means of consuming content the tax might not be a tax at all. You need to take a look at what "break even" is on sales for you app before you make this call.
I suspect he means the WSL given the context of the previous sentence.
Certainly startup equity is a) a risk and b) sometimes hard to quantify in real dollar terms. But if the startup is successful, equity value is very real and should not be ignored or swept aside. My advice: Don't join a startup unless you believe in its growth potential and your compensation package includes equity. Without the equity and the potential that comes with it, there is little reason to join a startup. You might as well just go with an established company instead.
> You are being given the numerator without knowing the denominator, so it is all worth zero until you get to see the Cap Table. Most startups wont let you see the Cap Table.

Every single time I've accepted a job at a startup that offered ISO stock options, I knew # of shares outstanding (the denominator), terms of all funding rounds, strike price, exit strategy, total amount of money raised, who the major investors are on the cap table, etc.

The jobs were at startups funded by the best investors in the world and high caliber founders who valued transparency. One went on to become a unicorn, and the other is an extremely early seed stage company where I work now.

If a startup isn't willing to give you information beyond # of options granted, then that is a red flag in my book. Not all startups are like that.
Sure, but who tells the client what the correct hash is?
people in this thread have a crazy assumption of in-car network security.

leave this thread with one single knowledge: cars have a single canbus network, with zero security. your radio, turn signal, engine intake computer, are all talking in the open over a single data wire.

anything you plug to that network can listen /talk to anything, and instead of security you have a priority bit (or a few of bits, don't remember) that is completely self regulated by each device.
I'll also mention the urban dictionary when looking up recently made up words.

Also, learning different languages usually reveals that you cannot think in the same way when using different languages. So you may end up creating new words to describe ideas the other language doesn't convey.

Anyway, languages keep evolving all the time ;)

You can go even farther, if less than 50% of the people studying it work in that field, maybe less than 20% work there? And their expected wages can't pay for the cost of the college education in 20 years, then it's very questionable to study in that field. Unless you are rich already.
Well, I would have been in 4th grade when Linux was posting about his free operating system, and we had an XT at home. My sister went to college in '93, so we gave her our old computer and got a brand-new 486/33. In 93 I was BBSing; 94 had a shell account, 95 had Linus' "hobby" installed on the family PC.. So I guess that was 8th/9th grade.

But I, too, often feel I "missed out". I guess it's part of the human condition :)
I don’t think the typical “change of variables” definition is bad.
You take the derivative of L along the fiber of the tangent bundle.
If the derivative is non-singular it defines an isomorphism in each
point of the tangent space with the cotangent space. And that’s the
important thing, going from the tangent bundle to the cotangent
bundle. Now we can use all the beauty of symplectic geometry

Look, the evidence is always surprisingly weak. This isn't necessarily because these things don't work, its because the epistemology used is terrible at evaluating these sorts of questions, when someone has bothered to look in the first place. See here:

Anecdotally my life experience is that exercise is the best possible way to combat depression. The other day I was crushingly depressed and had been for a week. I went and hit my heavy bag for twenty minutes and came out feeling fine. The effect was profound and easily felt. I don't need a study to convince me further; my lived experience is a superior epistemic method here.
There seems to be maybe one missing and that is the disproportionate bias from reputation.

People can completely hate people they've never interacted with before just because of what they hear said about them.

Once I stayed at a hotel with this guy who had some mental illness, bigoted ideae, and who thought I was gay. There was a gay pride parade going on that day nearby. He completely lost it and was yelling and harassing me. Of course he ended up getting escored out, but what happened before that was possibly even worse.

When I went downstairs the staff wouldn't even talk to me because he had gone down there first and badmouthed me in advance. I was just lucky several people came down and acted as witnesses. I also had a cell phone recording, but it didn't even matter at the time because they wouldn't even give me the time of day.

If you think about it, it's crazy how easily people can be made to put you down.

Right, tell that to a person in 3rd world who doesn't know where their next meal is going to come from. Money is not the most important thing in the world when you are making more than maybe $60-$70k/year in NA, but if you are making anything less than that, it definitely is the one of the most important thing if not the most important thing in the world.
It's not bullshit. But at the same time, I wonder why so many people do these majors. They mostly end up working on a unrelated field. If they go to university just because they are passionate about learning the subject and are willing to pay for it, that's great! But I feel it's just that they are pressured to go to college, they are pressured to "follow their passions" even when it will not work out, and in fact some menial jobs require a degree nowadays.

We don't really need (economically speaking) lots of philosophy majors. And maybe that's okay if people are doing philosophy majors for the knowledge, but I don't think that's the case. And if they want a good job, I think we should discourage these majors.

That doesn't mean we don't need philosophy. It's really important. But it doesn't make much difference if the people who have a degree on that work on unrelated things.
This isn't about GPS navigation systems in your in-dash screen. This is about hacking into a service linked to a device specifically designed to do what he did with it.

From the article:

>The hacker, who goes by the name L&M, told Motherboard he hacked into more than 7,000 iTrack accounts and more than 20,000 ProTrack accounts, two apps that companies use to monitor and manage fleets of vehicles through GPS tracking devices. The hacker was able to track vehicles in a handful of countries around the world, including South Africa, Morocco, India, and the Philippines. On some cars, the software has the capability of remotely turning off the engines of vehicles that are stopped or are traveling 12 miles per hour or slower, according to the manufacturer of certain GPS tracking devices.
I thought devs make more than data scientists? It's my experience that devs are in much shorter supply related to the demand, and their (comp or) value is usually higher.

It gives the app developer deploying the profile enough access to pipe all traffic through a remote VPN or attempt to redirect certain traffic through DNS resolution, with new certificate trust settings, to let you capture TLS and non-TLS traffic from your phone. It also gives them enough power to change the configuration of the phone this way at any time.
It’s a very common HN trope: go to any thread where tech salaries are mentioned and you’ll find someone whose sister’s boyfriend’s roommate makes $400k at Facebook, so therefore that’s a normal, expected salary for all tech workers. Point out actual publicly available data like Glassdoor or Salary.com and you’ll get a whole bunch of nit picks about their methodology or the fact that they report base salary only, etc.

Yes, there are likely outlier employees at outlier companies making huge comp but those have to be at least 2 to 3 standard deviations right of the average.
A program is not required to produce an output and is not even required to finish.

Wisdom of the policy aside, why is it implemented in such a seemingly insane way? Why not just look at the equivalent of last year's W2? While not perfectly representative of steady-state income, it's what many other income-based systems do and you can easily have a petition process for claiming that that year's income is unrepresentative.
Life is a lot better in Seattle. I'm over 50, no problem working as a dev or other roles, endless opportunity. If a job gets too stressful tell them to change it, or get a new job that probably pays more.

Long polling can work great as a bidirectional communication layer (send and receive messages over 1 connection). A few things that it would be worse with:

* Request headers are processed on each request. Even with keep-alive connections the request headers are sent/processed

* Message latency can be much higher in poor conditions because multiple requests have to complete to complete a loop (I think it's 3 connections and each connection can potentially be re-sent which means it can take several round trips)

* Not fully duplex connection, you can't send and receive data at the same time on 1 connection

* Domain limits imposed by browsers apply

* edit: binary message protocol can't be used

It's better for some use cases:

* Easier to implement (standard HTTP). WS is definitely much more complex to implement

* Easier to deploy (standard load balancers / proxies should work well)

* Takes advantage of keep-alive

> The Brazilian Navy has (...) in turn charged Mr. Marx with ''contraband'' of objects recovered from other wrecks in this country. (...) the Brazilian officials showed a catalogue of an auction held in Amsterdam in 1983 in which, they said, gold coins, instruments and artifacts removed from shipwrecks in Brazil were offered for sale on behalf of Mr. Marx and his associates.

> Several attempts to give Mr. Marx the opportunity to respond to these charges were unsuccessful. One phone call ended abruptly when Mr Marx said, ''Don't bother me,'' and then hung up.

I have to side with the Brazilian government here, not because I think they're right (I don't know) but because their action will lead to the least harm.

If Marx is right, and Brazil has its say, then the worst that can happen is that an archeological site will be buried in a known location for several decades until someone else will give another try.

If Brazil is right, and Marx has his say, then the worst that can happen is that an irreplaceable archeological site will be plundered in haste with 20th century technology (which is, let's admit, not that great in digging up underwater ruins without destroying them), forever losing an opportunity to learn more about ancient Romans who made it to Brazil.

Not all wonders have to be excavated in our own generation.
Thanks for the suggestion! I'll take a close look at it.
As mentioned in a footnote in the blog post, I think Gelfand and Fomin’s “Calculus of Variations” is very clear on its topic. Wald's "General Relativity" is slow-going, but excellent. No good textbooks on quantum mechanics or QFT exist; Weinberg's "Quantum Theory of Fields" is probably the least terrible on that. Nielsen and Chuang's "Quantum Computation and Quantum Information" is still excellent, but pretty out-of-date.

Also, to be clear, I haven't worked through most of Sussman, so I can't recommend it one way or the other. I was just commenting on the handling of the Legendre transform.
Severe depression leads to isolating behaviors. If you're not so depressed that you are able to leave the house and go somewhere, you're ahead of the game and excercise is just icing on the cake.
The "secret" (a link to another private whatsapp group to which not everybody should enter, just for easiness of organizational purposes in an event, so not much of a critical secret) was reportedly seen by around 5 people out of 200 in the group. No one of them bothered, if they did it would mean just a bit of explanation and taking them out of the new group. By all means, being able to quickly make a correction was not too late and was not security theater. Your position is that of "if we cannot solve 100% of a problem, there is no use to solving 95%" which is clearly a false dichotomy. There is value on editing or deleting messages after the fact of sending them.

Case in point, I just edited this message to change all "_" to "*" to make italics work. That's another use: fixing wrong assumptions about usage of technology itself.
> Point out actual publicly available data like Glassdoor or Salary.com and you’ll get a whole bunch of nit picks about their methodology or the fact that they report base salary only, etc.

So you don't have a counter argument is what you're saying? The truth is those site are insanely flawed and if that's what you're using to form your basis for negotiation then you're at a disadvantage period.

Compensation is often base + bonus + equity. For sufficiently senior positions, the equity component can be almost as much as the base salary. If the equity is liquid, then why is that not relevant?

FYI new grads at any of the big tech companies are bringing in close to ~$200k in total compensation their first year. It's not just someone's sister's cousin. It's a majority of engineering new grads who work at any of the BigCos which employ A LOT of people and are constantly hiring.
Why would you join taking compensation not knowing it’s value? In my experience companies will always tell you some mix of shares outstanding, current fair market value and sometimes even the valuation for the next venture stage (I don’t see why as an employee you need to see the cap table). While predicting the future is impossible, this information helps to assign a non-zero value to the options.
Since you put in all the work! It's the binomial distribution [1]. What you've done is to simulate the distribution of a sum of binomial distributions.

Your point of there being more than two types of rare cancer and that any selection of outliers over all the types would give rise to the same sentiment is totally correct.

I did the quick mental calculation with one in a million. As you see in your simulation the difference between 1e-5 and 1e-6 makes all the difference here.

Better to ask what you can be part of now than worrying about what you missed.

The shape of computing has changed a bit since then but there's still a lot of very interesting work now and going forward.

But I totally get it... I've felt that way before about tech and music. In the case of music I spent so many years only paying attention to rock from the 70's, 80's and 90's and telling myself music was dead now, but it is not... it's just different and needs to be discovered.
There has always been a limit to what people within a community will tolerate, even in the name of "freedom of speech."

It used to be a widespread virtue for people to cite "freedom of speech," let people say their piece,then just go on with your own life. The people who were going around trying to persecute others were bigots trying to exclude Jews and Asians from their clubs. (Happened to my family.) The people who were going around to people private lives with toxic behavior justified by their beliefs were people like the Klan and the Westboro Baptist church.

Now, people proclaim as if it's "mainstream," that it's a virtue to give people "consequences" and engage in the same kind of impingement on private lives, exclusion, and active persecution those bigots once engaged in, then call it "justice."

It's quite a huge difference in society. Such active persecution used to be the sole province of widely recognized fringe bigots. Now, it's supported by politicians at the national level and it's claimed by people who purport to be mainstream and normal.

It's no longer a live and let live society. We should be suspicious of those who would engage in an Orwellian retcon of the past, and pretend it was always so.

Your financial advice is solid. However I hate Big Co politics (it’s caused me mental health issues in the past) and I enjoy being able to be a generalist. Of course some people thrive in highly politicized environments or enjoy being specialists, so in that case, a Big Co makes perfect sense.
