Dealing with mobile carriers is really hard - their tech stacks are awful and outdated and they see everything as a threat and try to protect their turf by any means.

Hm, I happen to live in Germany. I have yet to see a map that's years out of sync with reality from GMaps... and I don't use much public transit anymore (mostly because I lack that kind of patience).

It is my understanding that public transit information has to be offered by the respective Transit Authority, and that does not currently happen with GMaps. Chances are Here is paying top coin for that.

When doing a search on "My Location -> Leipzig HBf", I get oneidentical street routing (google taking construction sites into consideration when calculating the driving duration). Google gives me an alternative strreet route, Here doesn't. Google suggests I can drive to the nearest airport and fly over there (making the trip 3 hours shorter) - and gives me the estimated fare. Here gives me the information about using the train (making the trip two hours longer) - without giving me the fare.

As of now, I do not see an advantage... can you give a more specific example?

I thought you were being a bit hyperbolic until I watched it. Nope, it was stellar. Thanks for posting it for those of us who hadn't seen it, it was fun, and even better, I learned some things about something I thought I already understood.
Cool collection! Thanks, added to my shell startup :)
I'm frankly a bit offended by the type of computer science and computer programming that you dismiss as not a "real job".

Sure, Conway's Game of Life is a toy problem, but the optimizations used to make it run fast (which go way beyond mere bit-twiddling, btw) are useful tools and practice in a programmer's mental toolbox, for solving real problems.

Certainly, a programmer who "merely" plugs frontends into backends with databases or whatever it is that you consider a "real job" in programming[0], doesn't need to know about bit-level optimizations to do that job. But I would argue that even then, it makes a better programmer, knowing about that sort of thing, broadening your bases, versatility and well-roundedness.

Doesn't mean you have to use it on problems where it's not supposed to, or premature optimization.

Elsewhere in this thread you say you don't need low-level optimizations because Redis handles this for you. But you wouldn't say that the people researching, designing and building Redis weren't doing "real jobs", would you?

I think broadening your bases is actually a pretty good reason for learning about these (or other) things. Because you seem to have a pretty narrow view of what a "real job" is in programming. In particular that you can't seem to come up with any good reasons for knowing about bits, except IEEE floats.

What about graphics programming, usually pixels are packed into a 32-bit RGBA word, you need some basic bit operations for this. Most situations abstracting that away kills performance.

If you need to read out sensors from a device, you're probably going to come across bits (and many other ancient programming lore) somewhere along the line.

If you write code for small / low powered hardware (like Arduinos or equivalent) you are going to need to know your way around bits and bit-manipulation code is very welcome there.

Knowing about these techniques is also important because sometimes they suddenly become useful in a whole new or modern context. Take antirez's Feistel network approach to this fizzling-problem, for instance. That's a cryptographic primitive now used in a graphics context. You can make exactly the same point about it, that a programmer who is supposed to do frontend/backend/db work, should never write code like that, and indeed this is true, you most definitely should NOT be coding your own versions of crypto primitives in a context like that (I'd argue that's even worse than bit-twiddling).

[0] I'm kidding, I respect the work that goes into it. I think it's boring as hell, but it's a lot of work and not all trivial either.
That sounds a bit dangerous to the lay person...
ArgParse: an argument-parsing library for Swift 4
I used to think CS was the exception to my college is worthless philosophy. Then I started dealing with recent graduates. The quality of the education coming out of supposedly decent schools is abysmal. I think modern college is proving itself particularly ill suited for the modern job market. They are teaching out of date skills at a glacial pace. In fact, it’s gotten bad enough that I don’t even ask about whether a candidate has a degree, they are simply irrelevant.
Could you describe the misalignment? That's interesting - Arduinos etc have made USB 2 pretty ubiquitous, so this could be useful knowledge.

(I'm tired and needed to re-google it, so for anyone else: Full = 1.1/12Mbps, High = 2.0/480Mbps.)
Is this really leftism or a provocation? Either way it backfires by playing right into the simplistic right narrative of theft and jealousy and makes the left look like clueless out of touch jokers with no solutions for innovation and a weakness for ill thought sledge hammer constraints. It's a disgrace.

The bigger problem is significant gains in western democracy and liberalism are being watered down with serious issues around regulatory capture, surveillance and accountability growing. Or current systems, laws and legislation would have been dealing with some of the privacy and market problems caused by Google, Facebook and Amazon.

The EU is trying but it's not in the US interest to interfere with the growth of these companies for many reasons from surveillance to market domination so they will not meet legislation here.

When I visited the whales exhibit at the Museum of Natural History in New York, 3 years ago or so, they showed that early whales were kind of like alligators, so I'm not sure why this is a new discovery. Perhaps it just firms up the timeline for when their feeding mechanism changed, or maybe there's some other detail that's escaping me here.
A Blue whale can consume as many as 40 million krill per day, if that's not a predator, not sure what one is.
> I was lucky enough to go to college in Europe, where it's basically free

This is not at all the case in England unfortunately - I guess I really should've considered studying elsewhere in the EU where fees are better.

With that said, I still think I've got a better deal than most US students since the fees there just seem to be ridiculous.

> I then moved to the US debt free

This is something I've considered, but I feel like I'd miss being an EU citizen, the NHS and the culture etc. How have you found it since you moved, if you don't mind me asking?
I did a BA and an MA in the arts. I don't work in the arts now, 10 years later, but on a daily basis I see how that experience gave me tools and skills I didn't have at the end of high school that help me succeed. Just in terms of professionalism, communication skills, and being exposed to new ideas and challenged about how I see the world. As well as, occasionally, a specific piece of knowledge being useful (eg I'll do musical transcriptions from time to time). I was a disaster coming out of high school, and college was the ideal environment for me to become more independent and less of a jerk. I almost studied commuter science, but ended up picking music and English, which has led me such different and interesting places.

One caveat: I come from a country where you don't have to go into debt to attend college. This frames the experience very differently, I think.
Business roll out mobile apps over websites – Why?
Sort of.

The underlying infrastructure is quasi-nationalised in many cases and the private companies sit on top.

For an example look at the big six (largest electricity providers) they all buy electricity from the same place at the effectively the same price, they don't even maintain large parts of their own infrastructure.

The way it was privatised was the worst of all options.

Same with the railways. The companies Joe public interact with don't own the track etc.

It's a truly British solution, what's the worst way? Let's do that.
I can't imagine anything more likely to make a teenager want to go to college than a parent saying that they shouldn't!

My wife's parents didn't want her to go to University and only changed their minds once she became a barrister (advocate here in Scotland).
I wonder how practical a portable laser gun would be, as I'm imagining a laser diode array would need to be amazingly powerful (I'm assuming much greater than the 40W version in the video?) and they'd require a very beefy power source.

It seems diode lasers are up to 60% efficient?

It looks like you can get extremely high power pulsed laser arrays though.
And you buy something for that debt.
You buy freedom.
In those 4 years, you can basically do anything you want- like really do it. Want a laser to print 3D Lightning into mid-air, yeah we have one in the lab, go and grab when its not used.
Want to write some software? Congrats, you got 4 years, and will recive a good grade when you present your program as a project.

All this needs a certain personality type though- and there are some for whom college is a lot of closed doors and hostile personalitys.
There are some who cant self-organize, and who by staying would force organization from outside upon all other students.

I miss my college years. The many moments, i found some pocket universe of complexity in places least expected.

It's weird how a lot of people think they didn't learn anything in college. I thought so too, just after finishing. Now I can think of a lot of things that I maybe didn't learn very well, but I heard of in college.

- Some guy writes about Bayesian networks. Lo and behold, I remember doing it in college.

- Someone floated the "20 most important equations" meme and I've seen them all at college or at work. I can't say much about each of them, but I definitely saw them and know roughly what they are about.

- Coding. We did some of that in uni, though not in depth the way I do now.

- Pretty much every economics topic you see in a newspaper.

It wasn't that much of a waste of time. Kinda like a buffet where you try a few things so you know they exist, which perhaps is what college is supposed to be.

Having to prep for exams killed the joy though.
Free email course on Business Model Canvas 101
In the beginning of this year, we at ElpisDesign had few objectives for this year. One of the most crucial points on that list was to share whatever we have learned and whatever we are learning with others. 4 months back, we created a Design community - Design Delhi which now has 700 + thinkers, and so far we have conducted 5 events. :) Moving in the direction of sharing we are extremely pleased to announce that we are launching a series of byte sized Email Courses.
The first course is on "Business Model Canvas 101". This course is ideal for business owners or aspiring entrepreneurs. This tool has been a lifesaver for us and for many of our clients to whom we have had the honor to teach and share it. There are many benefits to use a Business Model Canvas, but we will just give you one- IT GIVES YOUR ENTIRE TEAM A REFERENCE POINT. You can save a lot of time and energy if next time every team member of your business is on the same page.
This course will start from the Friday of this week and will be delivered to your inbox every day for next 10 days. You will just need to take out 5 minutes of your day. In the end, you will also get a small quiz to test what you have learned.
So hurry up and Subscribe here for the course: https://goo.gl/UpNeiu
Anything construction related. Personally I'd love to take on the challenge of building a stonemason bot.
I've been in industry 40 years and can think of 2 times I directly used what I learned as part of my job.

1. Calculating the temperature distribution across a fiber being heated by air (spoiler: it's uniform).
2. Calculating the annual rate of return from an investment from an Sybase SQL server without resorting to a procedural process, i.e. using only the ln, exp, and sum functions available.

The second really goes back to high school math so doesn't count as a reason to go to college.

NYC Algoriz (YC W17) Is Hiring Lead Engineer / Future CTO
In my experience only maybe half of people actually use much of what they learned in college in their job. Many people don't end up in what their degree was and also many jobs are learned primarily through job experience. If you think about it most people learn more practical skills in the first year of having a job than in 4 years of college. I think that when people spend such a large chunk of their time and money on something they expect a little more results and he is exaggerating because he is frustrated with it.
Nt really related to gigster specifically or this raise, but…

I would be curious to hear the “BHG” theses from various companies. At a sufficiently ambitious scale, the thesis would have to be tackle some core (and IMO open) questions in economics, the “theory of the firm” family of questions.

One (not the most ambitious) thesis could focusing on standardised tasks, anything from uber to tax returns. Another would be focusing on well defined tasks, like building an app from good specifications.

More ambitious ideas would need to deal with poorly specified (or completely unspecified) jobs. Jobs with substantial creative elements. Jobs with a risk of failure. It would need to deal with cross collaboration.

I don’t know much about this area, but it would be interesting to hear about it.
Model-Based Machine Learning by Winn and Bishop (Early Access)
Yes, I agree that content silos are a problem.

But with IPFS, [1], (which is a federated protocol) you can "host" a HTML file or video or any content without any difficulty yourself.

I'm not sure if it would be suitable for the functionality in Facebook though (sharing stuff with friends only), sending messages, so that's part of the reason why we need more research.

The network effect of Facebook can be mitigated by introducing laws that open up competition, like the telecommunications acts, which opened up the market for telephony.

Yes, that bothered me too. Not everyone is you.
Didn't we know that already?

I mean, the evolution of Cetacea is fairly well understood by now. We know they all derive from a terrestrial small carnivorous artiodactyle. And all descendants had sharp teeth until relatively recently. Even today quite many of them are still active predators.

Yes, you can assign values to different world versions, but each version would have their own values.
It's a meaningless (to others), subjective categorization. There is no solution to the trolley problem where both branches agree to let one branch die.

I didn't mean that I do not have any preferences, but that my
preferences aren't special or better than others' preferences, in the same way that
another version of the world (where Pratchett's wishes were overruled) is not a
better world than the current one. I think I'm skirting close to
Leibniz here. Yes, the world could be better, but it would not be our world, and it
would only be better to some of us, and worse for others.

It's highly unlikely that your best Kafka is my best Kafka. As such there is no Best Kafka. The world in which I help Kafka finish The Castle is one in which (for want of a nail) a trillion years from now the Zormulons exterminate the Qdhraxians. I doubt the Qdhraxians are happy I at least got an ending to a story.

The mantra has always been "College isn't for everyone". I think some people have assumed this was pejorative and just directed at bad students or the poor, but there is much more to it. Maybe college isn't for you _right now_. Maybe you don't know what you want to study yet. Maybe you aren't yet mature enough to leave home. Or maybe money is a factor. But "Don't go to college" to me seems as naive as "Everbody should go to college."
>Snapchat is just a product, I think the real invention that you overlooked is the internet.

When I think about, I suppose it would be almost simpler to explain Snapchat than the Internet to a 18th century person.

Though, like you, I think I would try first to explain the Internet.
Yeah, created some great friends, have an amazing professional network, was able to do research with professors, and took classes in areas I wouldn't have thought to otherwise and the environment can't be replicated online.

This isn't to say that college is for everyone, but I don't regret my experience one bit.

the 24/192 downloads or SACD releases are often the only way to hear the album with real dynamic range.

Yeah, this is often true. Some of Green Day's (a band I've never previously been into) albums were released in 24/192 or 24/96 a few years back and they actually sounded really great, with real dynamic range.

Also true? The completely absurd fact that sometimes a vinyl rip of an album will actually have the highest dynamic range, even though vinyl has a much smaller dynamic range than 16/44 audio. Bands often use "loudness wars" mastering for the digital release and then proper mastering for the vinyl release.
> University professors are among the first to say "do as I say" without any motivation (and no, they do not "want you to challenge them"; they just tend to be very narcissistic). The first thing I had to unlearn from college is repeating prefabricated opinions (which I had to do to get acceptable grades).

This is so vague. What kinds of "opinions" are we talking about?

Your opinion on what topics the professor should teach or whether he should assign homework? Yeah, no, just sit down and learn the curriculum the way they've designed it. When you graduate and start teaching, then you can be a rebel and do everything your own way and prove to everyone they're doing it wrong and you're doing it right.

Your opinion on whether you should use method 1 or method 2 on your homework? Well if they're telling you to use method 1, it's because they're teaching it and want to make sure you learn it. Even if it's painful.

Don't forget the reason you're there is for the faculty to challenge you, not the other way around. Their job is still to teach you the way they know best. If you don't care for that and want to teach yourself, then indeed, don't go to college.
On that note, does anyone have good resources on building laser powered products? I figured it would make sense to start by reading an optics textbook. [1]

Something like Building Electro-Optical Systems by Hobbs. First problem is that I wouldn't even know which ones good.

The next problem I see and which the article touches on is that the wrong setting might cause irreparable tissue damage. Which by extension means that making sure that the variance is power must have a bunch of failsafe circuitry more so than the average meditation eeg startup.

I believe there are reliability test scenarios for electrical equipment in space, so i assume there's similar things for this use case. Would anyone be able to point in the right direction?

I can confirm, as a professor who hires PhD students and postdocs, I do give MOOCs some positive weight. Of course there are not one of the most important points in the CV, but they can and do help.

If a candidate already has experience or "traditional" qualifications in the subject of interest, a MOOC is not needed and probably will be worth approximately zero.

But for example, I have sometimes got CVs from candidates that had a formal education focused into topic X and are applying for a position to do a PhD in topic Y. Having taken a MOOC in topic Y tells me that they have a real interest in that subject and motivation to pursue it. They were not just applying because they saw the offer and they liked the location or the salary so why not.

For young candidates that are straight out of their Master's and don't have much more to show apart from their academic record, a bunch of MOOCs also shows me that they are people who really have an interest in learning, and are not just focused in ticking the minimum marks needed for their career goals.

So yes, definitely several times the presence of one or several MOOCs has had an influence in hiring processes I have conducted, and I know I'm not the only one.
I don't think so. Lasers are ineffective as lethal weapons (they are very effective as blinding weapons, which is probably worse and inhumane).
