I see. Thank you. I am sure for some that $15K is an investment.

I don't understand why you think 3000$ per seat is asking too much. If there's a market for cheaper products just build it. After putting in the work, you might actually think 3000$ is cheap.

I have never used IDA Pro but maybe the licensing comes with some sort of support agreement?

tpfour··on Lightweight versions of websites without all the bloat
Well I am interested in lite websites as well but this list contains about 20 links with roughly half that aren't "lite versions of websites". I am just wondering why this is the topmost story.
tpfour··on Lightweight versions of websites without all the bloat
Why is this the top voted story barely 40 minutes after submission? Are people really excited for 20 links, most of which aren't even "lite" websites?

Every now and then there's an odd top story on HN which makes me wonder who actually reads this site. I guess I'm not hip enough!

tpfour··on U.S. oil production to be equal to Russia plus Saudi Arabia by 2025
Oil glut? The analyses I've read point to an oil _crunch_. Are you being sarcastic?
tpfour··on FreeBSD 12.0 is now available
This is surprising. When did you last try it? A fresh install of 6.4 feels very lean and mean although a little sluggish when browsing the web for example. OpenBSD just feels really solid and simple, but powerful if you want it to be. The whole system feels very well integrated, nothing out of place. For my purposes I much prefer pledge to seccomp. It is much easier for me to use one of pledges' system call subsets, risking allowing a little bit more than necessary, than doing the equivalent in seccomp. Sure it might be more fine-grained, but I won't bother. I guess nothing stops developers from adding their own pledge syscall subsets to their kernel and recompile it, thus getting closer to seccomp control.

However my box doesn't feel as snappy as a lean Debian 9 install with xfce4. You have to decide if that's a dealbreaker :)

tpfour··on FreeBSD 12.0 is now available
OpenBSD if you don't mind the performance hit. It does feel a little bit slower when browsing the web for example. I don't mind.

The installation is very quick and then it just work on my t470. Documentation is excellent. Try it.

tpfour··on Go 2, here we come
My only experience with Go was around 2012-2013. It was fun, but I did not bother sticking with it. The forced directory structure was a little bit annoying and I found myself writing interfaces for everything. I'm sure people will say it's my fault as a programmer, but it turned me off from the language.
tpfour··on 2018 was a terrible year for Swiss glaciers
This is possible as long as precipitations are large enough. I would think this is still firmly an "if" proposition.

At first glance it does not seem obvious at all that the water cycle as we know it will be recognisable in 100 years.

tpfour··on 2018 was a terrible year for Swiss glaciers
> Huss says glaciers are essential to feeding Europe’s freshwater rivers, which provide drinking water to millions, especially in the summer months when there is less rainfall. “The summer is when we need the water in the lowlands.” he says, “If the glaciers are gone, this can have really serious consequences.”

What to do? Once actually "solving" the problem becomes a critical political issue, will there be anything left to "solve"?

tpfour··on Ask HN: YouTube down?
It just came back online for me.
tpfour··on [dead]
Prime example of what I would call a "suspicious submission". How did this get to the front page?

There is no information whatsoever, neither in the "About" or "FAQ" pages.

I am seriously wondering how much voting can be gamed. Can it? Is it?

tpfour··on Opinion vs. Skill on Hacker News
Your experience mirrors mine.
tpfour··on Bay Area city blocks 5G deployments over cancer concerns
Noobermin mentioned that OP compares a power vs an intensity (different units).

OP suggests that THz radiation is ionizing - it is not.

OP maintains that a lightbulb emits "10-100x" more radiation than a cellphone - at what frequencies? Is he talking about power or intensity?

tpfour··on Bay Area city blocks 5G deployments over cancer concerns
You could have a point if you put a little bit more effort into your rant. As it stands you are making a couple of factual errors, as others noted.

THz is non-ionizing, for one.

tpfour··on Beyond Spotify and iZettle: How Sweden became Europe’s capital of startup exits

    one team say one thing and the other read it as something else
To be fair, this happens to me with lawyers, wherever they are from. It has been a recurring theme of my interactions with them! Also, I will concede that I have never done business in Sweden. Just that from my own experience, there are bad apples and variable quality in businesses, wherever they are from :)

The article is pretty clear though, Sweden seems to be hitting above its weight.

tpfour··on Beyond Spotify and iZettle: How Sweden became Europe’s capital of startup exits
I have been doing business with people "elsewhere" in Europe. Never had any problem. You might be generalising a bit early. And if American English is a dealbreaker, or even considered a "plus", maybe your potential business partners pick up on this and could be irritated?

Some American companies I can send an email and get a response in 10 minutes. Others I have to send 3-4-10 and never get a response unless the account manager is called on his personal cell phone.

tpfour··on Unpatched routers being used to build vast proxy army, spy on networks
I finally convinced myself of building an opnsense wifi router after years of procrastination. I want to take back control of my network, or at least monitor it properly.

What are the most interesting network analysis tools I should look into? I'm talking more about high-level visualisations. For example, I'd be interested in keeping a list of every device that's ever connected to my network, and maybe get alerts upon detecting it. Or map requests/connections in real-time/historically on a globe in HTML5. Just some fun stuff to actually get a sense of what's going on in my network.

Any recommendations?

tpfour··on Data Engineering Patterns with Apache Airflow [video]
I couldn't be bothered to even pay attention to the material. I found the presentation repugnant.

From Prezi's homepage: "Harvard researchers find Prezi more engaging, persuasive, and effective than PowerPoint.". My experience was the complete opposite. The medium completely destroyed the message.

tpfour··on Um – Create your own man pages so you can remember how to do stuff

tpfour··on The Updated Pioneer Offer
I understand, but then wouldn't you reach 5x more people if you handed out $1000 instead?

I'm not against the idea, I'm wondering where the $5k is coming from. It just seems arbitrary and not very much without a proper justification.

tpfour··on The Updated Pioneer Offer
I am still not sure about the $5k. Why not $15k, which is what someone working minimum wage should expect to earn in a year?

The target population seems to be people who come from poorer backgrounds. $5k can be a lot of money for someone making only 3x that per year, but it doesn't seem anywhere near enough to get said person to focus on a project and especially not enough to get them to work on it and found a company. If the goal is to get "lost Einsteins" to spend time creating things and building companies, then you must give them the time luxury to do so and $5k just seems on the very low end of possibilities.

What am I missing?

tpfour··on Do electrons think? (1949)
I think you are abusing language here, probably not intentionally, and it distracts from the actual issue. You seem to understand the difference but for those who don't, here's a crucial distinction that's often overlooked by laypeople:

The Schrödinger (Dirac) equation itself is deterministic. Given a wavefunction at time t=t0, you can calculate its evolution to time t=t1. What is indeterminate is the observation of the observable. The distribution of observations is entirely determined. Only the result of a single observation is indeterminate: in the limit of infinite measurements, you would get the probability distribution back which itself is determinate. The various "interpretations" concern themselves with what happens at the time of measurement. For example, the Copenhagen interpretation says that the wavefunction, which was evolving deterministically, mutates into a new wavefunction which itself evolves deterministically. This act of going from one to the other is considered indeterminate and is given the name of "collapse". However the dynamics of each wavefunction is entirely determinate.

tpfour··on Wanted: ‘Lost Einsteins.’ Please Apply
It is, but that is not a particularly fruitful avenue of thought for the problem at hand.

I could annoyingly argue that OP and yourself choose not to each dedicate 20 hours more per week to work for even more money, money that you will send me so that I can work less at my day job and work on more interesting projects. But you can't do that because you have made other choices etc. It's a bit circular isn't it?

tpfour··on Wanted: ‘Lost Einsteins.’ Please Apply
> Everyone can find 15-20 hours per week. It's a matter of priorities and choices.

Do you have children?

tpfour··on What Are the Differences Between Clojure, Scheme/Racket and Common Lisp?
You should try Gerbil, a dialect built on Gambit Scheme. You can find it at https://github.com/vyzo/gerbil. I suggest you look into https://github.com/vyzo/gerbil/blob/master/doc/tutorial/http... for a simple HTTP server :)
tpfour··on What Are the Differences Between Clojure, Scheme/Racket and Common Lisp?
For me the most important difference is Lisp-1 vs Lisp-2. I had tried my hand at Common Lisp a couple of times before trying Scheme. The latter immediately felt "cleaner" than CL.

My favourite implementation is Gambit Scheme and I have currently stumbled upon Gerbil (cons.io), a dialect built on top of Gambit. It's just fun to work with.

tpfour··on Why some PhDs are quitting academia for unconventional jobs
Not OP but it absolutely depends on the sub-field, the most glaring difference being between exclusively computational/theoretical research vs "wet" lab, and even withing sub-subfields it can vary a _lot_.

Depending on the PhD program you can be required to take as low as 1 PhD level course per year. The "real" learning takes place by reading papers + lab work.

The transferable knowledge might not be the specific capacities developed (e.g. how to properly plan and manage a multi-step organic synthesis, how to write an SCF routine, etc) but rather to be able to sit down long enough and reason about the world to make hypotheses and test them. That in general is very useful and a skill most workers in the workforce simply lack. I do not say this to be condescending, it is simply my experience that there is a clear divide in the mental processes of people who went through at the very least a Bachelors' vs people who did not. It's not better or worse, it's different.

PS: Anecdotally, I have not completed my graduate degree for reasons of lack of funding. I really enjoyed what I did but TAing 2-3 courses per semester while working a part-time job (or two) to make sure I could get some vacation time once a year, pay the bills and go to the restaurant with my SO just wasn't worth it. As others have commented, money in academia is most definitely a winner takes all game. Experience showed me that in a cohort, it's mostly the top 5 or so students with excellent grades that will get the scholarships. Then you get maybe a dozen or two who live on ~1k a month and the rest well, fend for yourself (even if you have an advisor). I happened to be in a sub-field where professors were broke, so that was it. I eventually quit due to being absorbed in other (boring but paying) work, with now realising it was a mistake but a mistake that brought food on the table. Today I regret and want to go back, but you can't feed a family with $10k a year can you?
