That’s a fascinating case study. Thanks for sharing.

Not so long ago, I was designing visualisations for a different type of underlying graph structure, but one that had some similar elements in terms of “close” edges that could be drawn together, a desire to minimise edge crossings, and the like. I spent quite a while studying Beck’s famous London Underground map and its modern derivatives, and then experimenting with some of the same ideas mentioned in the article here. I too found that rendering clean, practical diagrams to show messy, real-world underlying data can be surprisingly difficult! I have a lot of respect for the Transit App team if they’ve successfully implemented algorithms that can produce output as beautiful as those examples in their general case.
Indeed. I saw "Shenzhen I/O" on HN, clicked because "ooh Shenzhen!" (been there, place of dreams for hardware hobbyist!) wondering what weird startupy thing it will be. Then saw Zachtronics. That's insta-buy for me, as it has been since SpaceChem and the flash games on his website.

Just as a different counter point, I have coded in lots of environments including factory floors full of thundering industrial equipment and in the Gobi desert using a noisy smelly diesel generator as a power source etc.

I think I did some of my best work when assigned a desk essentially in a corridor. A constant stream of people behind me, no privacy, noise etc. There was no half-concentration which privacy can encourage e.g. flicking to email/web every 5 mins. It was either get 100% wired in or don't bother trying. Concentration is partly a learned skill and being an environment of disruption is a training ground. Concentration begets concentration - if you have deep focus on a piece of work and made great progress, its much easier to get back to that state than if you have been farting around at the surface. If you have allowed yourself to indulge in "semi-work" then you are not like a rested athlete but an unfit one - you will have to train yourself back up to high-productivity.

The really tough environments have been temperature extremes (your mind/body just stops functioning), noise at the truly headache inducing level (sitting 10m away from a drive-train rig the size of an Olympic swimming pool) but the worst of all for me is emotional noise e.g. people bickering. Trapped in a small office with unpleasant people is where I say "never again".
Also, the name, I would have taken this tool as related to textures... not text.
The problem is that virtually every grade school math program will teach you rote practice... and then nothing else. Seeing examples and doing exercises is still key even if you're teaching category theory to graduate math students, but nobody would consider someone who had only mastered that part to understand the subject.

The efforts to de-emphasize it seem to be in the hope that it'll magically cause people to learn the higher concepts as long as you use the rest of the time to read passages out of a book about them. They've clearly been unsuccessful.
It's a cartoon, dude.
your employees don't even realize they're being ripped off.

Careful with your terminology there. To be "ripped off" requires there to be no other choice. Your car has broken down in the desert and the single mechanic within 100 miles can charge you what he wants.

In that light, it is not possible for an engineer contemplating accepting a job offer from Facebook to be "ripped off". He's in intelligent businessperson negotiating a deal with a ton of other options available. They can't force him to do anything, and if he sees an open plan office as a downside, he can negotiate compensation in other forms.

Personally, I'm happy to work in any environment you put me in. Stick me in the swimming pool and feed me margaritas all day if you think it helps your corporate culture. I'll assume you've done the math and factored in the drop in productivity, so I won't feel bad to watch it happen.

That's the nice thing about business. You can assume the other side of the table is also behaving rationally, and let him shoot himself in the foot if he pleases.
Well...a feeling is captured, not the feeling.
My laptop came with a DVD burner a couple of years ago. Maybe used once. I swapped it with a 1 TB SSD earlier this year but I can connect it with USB if I have to.
Yes. As long as I don't get the hard time and can continue future robbery attempts, I'm fine with that, given I will get caught in the first place.

Unless the idea is that Epi will all of sudden become affordable like it used to be.
Looks lovely. But their comparison with apple and google (https://medium.com/transit-app/transit-maps-apple-vs-google-...) is missing something: "works on a desktop computer". I have a surface 3 pro with chrome/firefox/edge installed, I'd love if there were some html5 web view onto this for planning trips in advance, where I quite like the larger screen size and the ability to screenshot/print just in case.
Thank you for sharing. By the way, your mother is a very talented writer! That was a pleasure to read.
Learn More about Postcard Printing Designs
Postcard Printing is among the most widely used strategies used in advertising and advertisement. This is in line with the fact that pamphlets come with a wide range of functions that enables you to achieve specific customers as well as pass across an advertisement message effectively. When considering this kind of printing, there are a number of factors that you should always keep in mind to help make the most of your advertising campaign. Style is among the most crucial elements that you should focus on in order to make probably the most of the investment. It's good to note there are different design choices you can settle for such as:
Bi-fold design is among the most popular options used in Postcard Printing.
It's preferred by many people because it is easy to use; it is affordable and highly functional. The product is collapsed and it forms different sections including the front include, back include and 2 internal panels. There are also different configurations to consider when using this design such as the 8, 12 and sixteen page designs. Consequently, you get to choose a choice that works best for your advertising and advertisement goals. http://www.55printing.com

Let's imagine a universe where research showed that factory workers gained significant productivity when they had private spaces to concentrate. Do you think that the factory owners would suddenly erect partitions? Of course not - at least not until they faced significant competition and were losing market share.

Too many people doing software over-inflate their importance to management. The reason why there are few offices at tech companies is simple. Management views software developers as factory workers, and they want to 'see' them working hard for the money that they're spending.

One would have thought that the Russians would know this better than anybody after the USSR's collapse but military might is meaningless if you don't have the economic might to back it up.

Russia is little more than a petro state whose economic fortunes are almost completely related to the price of oil.

Putin should be focusing on broadening the Russian economic base but is instead engaging in stupid military endeavors that are only kidding Russia friends. The EU would love to trade with Russia but his European tinkering had made it impossible for them to do so. The US is obviously not a fan. Give it a few years and he'll probably piss off China too (or they'll find the US and European relationships more useful) and the Ryssians will have little more to do than reminisce about the time they annexed Crimea.
That really didn't make the bosses happy. I quit for other reasons but looking back to it this could have also been one of them.
The problem with story problems is, as the article states, that they are never really presented in the open ended way they claim to be. You almost always teach a class a fixed operation, multiplication for example, and then give them a bunch of word problems where multiplication is thinly disguised.

A much better exercise is to give an absurdly open ended exercise. "I'm at the supermarket, which checkout should I go to?" is one I have used in classes before. You can get a discussion going and generate a lot of interesting ideas, and almost every time I do it in a class someone says something I've not thought of. Once students have given you some good ideas you can massage it into a model and do some more 'proper maths' work. Of course, this takes a good teacher that can engage and steer the class.

Also, the managers who sign off and make the final decision on which office plan to go with tend to spend most of their own work time meeting and talking to people, rather than needing to sit and concentrate on something for several hours. I expect this influences a cognitive bias when these managers consider the productivity level of an open plan office.

I've been using LaTeX for about 15 years, and my biggest problem is still the error messages. At least once a year I just end up deleting a maths equation entirely, and then writing it out again in tiny fragments, to figure out where the error is.

Some concrete small problems:

* Why can't I just write _, < and > in plain text mode? Why does an _ complain I'm not in maths mode?

* It's very hard to cut+paste code samples in for this reason. You can use verbatim, but then that often doesn't nest correctly inside various types of things.
That's happening to me often, too. But as I understand it, the habit of just starting applies to continue working on the unfinished work-in-progress project as well: starting a new project is your way of procrastination.

> "You can look at developer velocity and bug fix rates, to name a couple of readily available metrics."

How? If an office starts out open plan (which many of them do), are you going to move to new offices just to test the theory that it'll make your employees more productive? Plus, bug fix rates are a bad metric, bugs are not equal in complexity, and even if you try and guess at the complexity before working on a bug that's only an estimate, and one that doesn't take into account other important factors such as the level of churn in the codebase and the level of familiarity the developer has with the part of the codebase they are asked to fix.
It seems clear even from the summary that this process was used to test the silk fibers, not to produce them. Presumably the control silk and the nanotube/graphene-fed silk were both subjected to the carbonization treatment and the then the researchers tested the conductivity of both specimens.

As I commented to a different reply, skipping the render step does indeed remove the sawtooth, which is why I think the problem is in the 3D engine. Past that, it's not so easy to jump into a three.js-sized chunk of 3rd party code and find atomic things that can be turned off in such a way that everything else still functions.

(I mean, not to suggest that what you describe isn't useful - I'm just hoping to use profiling tools to attack from a different direction.)
> Objection 5. You’d never find enough teachers who were capable of teaching a course like this. To do it well, you need to have a very sophisticated understanding of probability, statistics, game theory, physics, multivariable calculus, algorithms, etc.

Objection 6: If it's hard to find teachers to teach it, maybe it's a little challenging for students (even though a good math expert might find it interesting).

Just because a math expert thinks something is interesting doesn't mean low performing students will find it interesting.

For a more HN friendly example - what bunch of high school students wouldn't want an IT class that taught compiler design, instead of stuffy old Excel? Even Python is more fun that spreadsheets, right?

Certainly there are large swaths of high school math that can be cut, and replaced with more relevant stuff. But some care needs to be taken that it's actually teachable.

The article does partly cover this though:

> Thoroughly road test questions before letting them loose on the nation’s schoolchildren. In fact, that applies to the entire course: make sure one has something that definitely can work before encouraging too many schools to teach it.
Possibly because they're molecular biologists, geneticists, and bioinformaticians who study the specific interaction of amphetamines with specially bred mice and observe markedly different responses in the amphetamine dosed knockout mice vs. the amphetamine dosed control mice?

In light of the events with Dropbox recently (Mac application issues, password dumps from 2012), what is the best cloud storage service?

I am looking for something that has full end-to-end encryption, high storage limits, and I don't want to use Google Drive, OneDrive, iCloud Drive or Dropbox.

I have heard of many different services that people have switched to, but what are the pros and cons of each. How much storage can you get? What are the pricing tiers?
> Runtime performance degradation is unacceptable

Requirements like these are not grounded in real software use.

In economic terms: a cheaper/slower software can be acceptable over a more expensive/faster software. Example: Java-based software vs. the same written in C++.

In reliability terms: a more robust / slower software can be acceptable over a more expensive/faster software. Example: Erlang-based software vs. C++ software on a network switch.

And so on.

Abstract/absolutist requirements like 'Runtime performance degradation is unacceptable' is not often found in actual software development/use.

Software usually has a multitude of different important qualities. Raw performance is just one of these. Especially one then needs to say what performance exactly and how to measure it. Performance can be measured in many ways: throughput, latency, micro-benchmark speed, etc. etc. Optimizing one (say, throughput) then has effects on others (say, latency). To achieve faster throughput, some functionality can be affected.
Really impressive demo. Thanks for sharing.
The GDS have done some great work. Nice to get a gentle reminder that they're still public sector crazies once in a while. ;)
Nothing. It is like using reserved world IPs in your internal network. There is perfectly valid range you can use so why not shift to that?
There are many people working on various aspects of DNA graphs - for example, there's now the FASTG format, a replacement for the FASTA format which is essentially a graph in text form: http://fastg.sourceforge.net/

Some assemblers (SPAdes?) have started to support this format, but most downstream software only uses the FASTA format (the non-graph version from a single genome/representation).

The mind is like a state automaton. It has states and it transitions between them.
Food is a necessity. Eating at a restaurant is a luxury, hence the tax.
That's true of a lot of practices, but when the feedback loop isn't as tight, it's easy for companies to ignore it. There are countless examples of big companies hemorrhaging talent because of their corporate culture, policies, etc. I've witnessed it many times with my own eyes. But that sort of thing doesn't manifest as the company burning to the ground in the next year and then people going "why did that happen? oh, it's because we lost Jim". Instead it looks like a failure to execute as well on big projects. But because there are always so many things changing from project to project, it's always easy to blame something else. And the management at most big corporations are loathe to blame themselves or their policies, so they always find some other convenient excuse.

This is a big reason why companies change character of time and transition from being industry powerhouses to also-rans.
This depends very much on how you measure success. Remember, News Corp valued MySpace for an $580 million.

“much harder to convey confidence for the policymaker who may make an important decision from advanced analytics with deep learning algorithms.”

The thumbs up gesture is an offensive gesture to Muslim cultures. Equivalent to the middle finger in US culture.

The "OK" circle with thumb and finger is offensive in Southern European countries (e.g. Greece), also somewhere around the same level of offence as the middle finger.

GDS might be part of the British civil service, but the UK is still a multicultural society with workers from all over the World here, including I believe, GDS. That might change in the next two years, but right now, it's who we are (and I personally hope it's who we remain in years to come).

It's not "political correctness gone mad" to choose a hand signal that isn't offensive over one that a third of the room might find offensive. It's just polite.
A talented 21 year old could have 10 years experience working on software projects with 5 years leading a team on product strategy. It's unusual but it's not unheard of, especially with today's level of access to computers and programming languages. 10 years ago was 2006 - every browser was a programming environment even then.

Equally possible, a 51 year old might have spent the previous 50 years in non-management roles and have no experience at all.

In project management and tech, experience and age are not related.

Not only that, if I recall correctly they were simultaneously telling another part of the government (the FDA) that the patent made generic substitutes for the Epipen impossible. The argument that the classification "goes back decades" probably doesn't hold much water, since there were generic substitutes for it once upon a time.

Capturing the interest must always be first.
So to capture the interest, one must use math applications like game or physic simulations that allready captured the audience, allow beginners to modify the laws and abstractions within and create a "im at home with this"-intuition to delete the "im just not cut out for math" bias.
Questions would not come from the teacher, questions will come from the students on how to modify the application.
My problem is more about bikeshedding than anything else. Every morning I start my work enthusiastically but then obsess over stupid things like the variable names, optimization, too much refactoring, indentation even sometime (like it would be so good to see all these = signs to align.. aaargh) and then just mentally exhaust myself with these trivialities and then it's back to reddit or hn. Worst part is that I'm aware how useless it is to obsess over such things yet I still catch myself doing it way too often these days.

Or being good at listening to, understanding, and learning from other people's experiences to recognise those pitfalls when you encounter them yourself.

This is exactly why accelerators like YC put so much emphasis on mentoring. Being able to talk to someone who has already been through something makes you much less likely to handle a similar situation poorly. You don't have to have direct experience of a pitfall yourself to understand it.
So, agreeing with that, are you aware of a specific terminology or theory of easy-to-measure vs. hard-to-measure costs and benefits?
