dalai··on Show HN: I made a Chrome extension that helps battle impulsive procrastination
I know, but somehow the motivation is not there, especially with side projects. I started a couple that aimed at improving our internal stuff, but they are sitting there. Everybody is positive until it is time to deploy/use something new. I did manage to read quite a bit and try new things the last couple of years though.

In the end, it is always lack of motivation I guess.

dalai··on Show HN: I made a Chrome extension that helps battle impulsive procrastination
My #1 reason is that I don't have enough to do.

I've complained about it so often to colleagues and supervisor it has become a running joke, but nothing changed. Previous job was even worse. I've been doing 2-3 weeks of work, followed by 1-2 months (if not more) of just sitting there, even when I have 2 or 3 projects in parallel. Somehow everyone else seems to be busy all the time.

dalai··on Why I'm not a big fan of Scrum
The article is also criticizing their particular version of scrum. For example "collecting points" or obsessing about them is not unadulterated scrum; the word points or planning poker are not even mentioned in the scrum guide. Any good developer, scrum master or book on scrum will tell you that story points are not a performance metric and they are only to be used by the PO and just for planning ahead.

There is little to criticise about pure unadulterated Scrum because there is surprisingly little prescribed and what little there is they openly tell you that you can change it in the retrospective. The real problem is that management, agile coaches (and unfortunately sometimes also some developers) often want to religiously apply every little thing they ever read in a book and seemed like a good idea. I think that solutions to all the problems the author mentioned are possible without deviating significantly or at all from scrum -- should that be important for whatever reason. The only prerequisite is that everyone involved is open to change.

dalai··on Federal health expert drop flossing from health guidelines
All the dentists I've tried so far in Germany have recommended flossing. The last one actually showed me how to do it properly and gave me a free sample to use until I bought my own. Perhaps things are changing here too?
dalai··on Microsoft to Cut 2,850 More Jobs in Exit from Phone Business
> how they think Nokia would've fared any better than HTC (or Sony, or Motorola)

Back in the day Nokia had good hardware, a 40% marketshare, brand recognition, a loyal customer base and a wide distribution network. Certainly noone knows what Android could have done for them, but theoretically they were at a better position to take advantage of it than HTC/Sony/Motorola.

dalai··on GitHub is down
> Mixing the two is convenient, but can stifle innovation.

Could you elaborate?

I think I've heard the argument before, but I don't really see how. These outages show up again and again, partly because people cannot access the project issues.

dalai··on The text/markdown media type
I personally prefer Asciidoc(tor). The syntax for the basic stuff (headings, source code, links) is at least as easy as for markdown, but it also allows more advanced cases (tables, splitting into files, text substitutions, etc.) without resorting to writing html or using external tools. Asciidoctor also directly supports the markdown style for headings, block quotes, etc.

I see markdown more for writing a quick note or something that will not exceed a few pages.

dalai··on Europe abolishes mobile phone roaming charges
> They are in the EU also ;)

I thought they capped just the roaming charges, isn't calling to mobile numbers in other EU countries still (relatively) expensive? My german carrier currently charges 20 times more for those.

dalai··on A practical Git introduction
Honestly, since when is that a great feature? I can't think of any other piece of modern software that requires that of its users (other dvcs with similar feature sets included). Noone should care about "internal" interfaces, no matter if they are easy to learn or not.
dalai··on A practical Git introduction
I am not sure what your point is. Subversion, git, hg, darcs all get the job done. Was your choice of git based on its superiority over the other ones or just a side effect of its popularity? The problem with git is not that you will run into issues, it is that other vcs provide a saner ui and require less of their users without missing on features.
dalai··on Fixing a 37-year-old bug by merging a 22-year-old fix
DE, FR and IT have the same currency only the last 15 years or so. One would expect that they would be using the same conventions because of the history and relationships between CH and all of these countries.
dalai··on iPhone 6 Plus bending in pockets
True, but I would assume that most people have a reasonable expectation that their phones will not get damaged in typical usage scenarios. And yes, I do think that putting your phone in your front pocket is typical. In my view that means that there is a design flaw.
dalai··on The most expensive lottery ticket in the world
And how many fail before they get any backing but after sucking a lot of money? The 1 in 10 chance of success could actually be optimistic.

Anyway I think the 90% failure rate might be based on this: http://www.wamda.com/2013/02/90-percent-of-tech-startups-fai...

dalai··on MH370 assumed to have crashed with no survivors, says Malaysia Airlines
It only took a couple of days to find where the Air France 447 crashed despite its location. Moreover, I doubt either accident would have been prevented or people would have been rescued if the precise location of the crash was known sooner.

There is some value in knowing early where an accident occurred, but that is rarely a problem. How much is it worth to fix it for the few cases that happen in the middle of nowhere?

dalai··on Failure is an option
I think his point was that is should also be an option in large, proven and socially important markets.
dalai··on E-mail didn't really evolve since Gmail. Why is it so hard to innovate?
> conversation threading

I believe this existed before gmail

> gigabyte storage

was not a tech problem before

> speed

in what way? the ui was and still is as fast as most lightweight desktop clients

> powerful search

maybe, although some clients supported powerful search with regex before

I think gmail was not that innovative, but it did bring everything together very well, in a very user-friendly way, along with some new-ish stuff like tags and the no need to delete anything.

dalai··on College considers basing president’s salary off that of cleaning staff
It is not about basing his salary on that of the cleaners. It is about having a limit on the range of salaries in the organization and the cleaners happen to have the lowest there. The idea is that the extra profits should be shared by all the employees and not collected by the top executives.

As to why they wouldn't just leave, well let them. You could hire better faculty members and you will have a sparkly clean university that can attract better students. Your research/teaching statistics go up and you can pick more funding. At some point other universities will follow your example and administrator salaries will normalize.

Not going to happen though .... more likely they will outsource the cleaning so that the president can earn 10x the salary of the IT stuff. Then they will probably outsource IT as well ...

dalai··on Machines are better referees than humans but we’ll be sued if we use them
This is not done by the publishers. They only provide an online system to do so. The editors and reviewers are other scientists.
dalai··on Steve Jobs time capsule dug up after 30 years
So much wrong with this coverage. The only thing new is the exclusive "fake" find video. From a cnet article back in September:

But Jobs' mouse wasn't easily found inside. Rather, it was hidden amidst hundreds, or even thousands of other artifacts last seen in 1983. So the "Diggers" team had to wait a few days before reaching their goal.

Which also begs the question. From thousands of artifacts the only thing worth a photo is a mouse?

dalai··on UBook – Markdown for eBooks
If it is not meant to be hand coded then I would think that starting with Markdown is a bad idea. Markdown was meant to be human readable with minimal markup. This means that there are many limitations as to what you can represent in Markdown.

To me, it would make sense to start with something more expressive. There are many different types of books (fiction, technical, poetry, interactive) and many types of semantic information that you will need to encode that publishers may require. Moreover, it is not just semantic information you need to capture. For some books the placement of the elements on the page, the font used, etc. may be important. If this format is also meant as an intermediate format for printed books then you only need to take a look at LaTeX and its numerous packages to get an idea of all the different things someone might require.

Even if you decide to go with something like Markdown, it makes sense to look at mmd and pandoc extensions (e.g. for tables) before coming up with another syntax.

dalai··on How to stop feeling lonely
> I agree that getting out of loneliness is hard but it's not impossible.

I don't disagree there. My point (which I probably didn't really make) was that you can't have a recipe for it. Too much depends on the particularities of the person and their situation.

> I don't know how big your city is

I live in Munich, which for Germany is big and quite international.

> Don't get me wrong but your post sounds pretty negative

Maybe I focused too much on the bad stuff. I do have some friends, I do have the opportunity to go out from time to time. It is just that these relationships are superficial and not as fulfilling. Curiously, others do not seem to mind at all.

> Then, why don't you change them?

I am actually in the process of doing that even though, professionally, it is probably a bad move. I've been applying to different places and positions for some time now, unfortunately I haven't had much luck so far due to various reasons.

dalai··on How to stop feeling lonely
I understand what you are trying to say, but I think mercer (in a sibling thread) has it right. A lot of us are in environments that feel like they are designed to keep us separated after we enter our professional life. This is particularly true for people that have moved by themselves to a different state or country and basically need to build a social circle from scratch. And this gets more difficult as you grow older.

I live in a central European country for four years now and I find it extremely hard to meet new people even for a superficial friendship.

- I have very few coworkers, but even if I didn’t, people tend to keep professional and private life very separate here. Some actually think they have “enough” friends and you might never get through to them no matter how much you try.

- In my home country I would usually meet people through friends of friends, but here my friends will rarely bring anyone else of their circle when we go out (even when asked).

- Meetups are also a big failure for me. Most of the time they involve huge groups that are very impersonal. They involve people that are here for a month up to people that have been here for 20-30 years and have their own cliques within the meetup. The first year I kept going to the same meetup and kept introducing myself to the same (more or less) people and held the same discussion over and over. Each meetup was as if I was there for the first time and needless to say, I didn’t make a single friend from that. Even in the smaller ones, it seems that most participate either to spend a night away from their spouse/“real” friends or just for the activity.

- Going up to talk to random strangers is also not very common here, but even if it was, it is unfortunately impossible for me. I feel incredibly self-conscious and uncomfortable. I tried it when I was in the US where people are more open and I honestly hated myself. I doubt PUA literature would help.

Anyway, I don't want to be too negative and I also have me to blame for the situation. What I wanted to highlight is that it also depends on the cultural environment and the particular circumstances. To me, it is quite indicative that we have dating websites and meetups and social web sites and whatnot but we are generally more lonely.

dalai··on Ask HN: Making extra income with books
Why a failure? As you say this is a niche topic and if the info is correct on Amazon, it has only been out a year and a half.

I am an author of a robotics book in an even more niche topic and I doubt our royalties totaled more than ~$5000 in the 4 years its been out (no upfront payment). I've always considered it as something to put on the CV more than anything else.

dalai··on Is Economics a Science?
Do they actually have prediction models that work? Goldman Sachs is not an outside observer. Every time they make a public prediction they are also affecting the outcome. The same goes for several well-known economists. Even if the prediction is not public, Goldman Sachs is quite capable of influencing a lot of people to get the outcome it wants.
dalai··on Think piracy is killing the music industry? This chart suggests otherwise
Well the problem with trying to counter the argument that piracy is killing the music industry is that we are talking about potential sales that would have happened in a universe where no piracy existed. I doubt the graph will help much. They can still claim that with the trends before 2004 the total revenue should have exceeded $100 billion so they still lost $40 (imaginary) billion.
dalai··on Open Letter to My Students: No, You Cannot be a Professor (2011)
I sometimes wonder whether there is indeed less need for professors or whether it is easier and cheaper to use postdocs, adjuncts, "research professors", etc. for the work that professors are supposed to do. It appears that universities are trying to avoid offering tenured positions at all costs. Florida polytechnic for example adopted a non-tenure faculty model which according to its Board of Trustees will help recruit and maintain top talent[1]. I wonder if they actually believe that.

When I was a phd student I did an informal check on the professors in my department. Even though it was no ivy league school, on average it took them 2.8 years from entry into the phd program to getting a tenure-track position. Now 2.8 is probably the average number of years as a postdoc you need to have.

dalai··on The Ph.D.-Industry Gap
A "data scientist" or a "programmer" are hardly senior level positions.

In my experience as a PhD with (currently) almost 4 yrs postdoc experience, I rarely get an interview when I apply for an industry position. I think there is a good element of truth in what the original author is saying about a gap. As PhD students and postdocs we do a lot of things. We have to write code, we have to manage students, teach, publish, apply for grants, manage research groups or entire projects, handle scientific and financial reporting, etc. The problem is that our skills don't exactly match company requirements that normally have different people for most of these tasks. To make things worse, people tend to believe that we will be arrogant pricks who will demand really high salaries even though we are clueless about how things work outside academia. Just look at some of the comments here.

For an entry level programming position a recent CS BSc appears much more desirable and cheaper than any PhD. I doubt that we even get much of a chance to show how good (or bad) we are. For higher level positions a PhD rarely has the "right" experience. What we are left with is usually something that fits well with our research. This is what the author found and as far as I know he is not in the minority.

dalai··on Death of an adjunct professor
A tenured professor though can get $20k per class or more, assuming that he/she is only teaching and not involved in any research (most start with 3 courses per year). Of course many tenured professors also bring money to the university through grants and whatnot, but that is not always the case. I know of some that get more than $250k a year just to provide prestige to the department and maybe teach a course now and then.

In any case, it doesn't matter if the class size is 10 or 50. You still need to prepare the same material, you still need to be there for the same amount of time. $3500/class sounds like a bargain to me. A TA earns more.

dalai··on The Two Envelopes Problem: the most boring paradox in the world
The issue as I see it is that the probability exists that the other envelope contains Z/2 or 2Z, but not both - ie. the probability that one of those exists negates the other from existing, because in order for both to be possible you're introducing a 3rd value where only 2 existed at the start.

So there is 50% probability that the other one contains Z/2 and 50% that it has 2Z. Do you disagree with that statement?

I have two values A and B. I ask you to select one. What is the probability that the remaining value is C? Obviously it's zero.

No it doesn't. According to the problem, both 2Z and Z/2 are possible and you don't have the information to decide either way. Think of a simple coin toss, before I show you the result it is 50-50 to be heads or tails, even though it is just one of the two.

dalai··on All-New Kindle Paperwhite
The DX is not very good for reading pdfs. It does not render them very well and the pdf viewer is lacking in features. This is remedied a bit with jailbreaking and using other software. Personally, I am still disappointed at the lack of official updates for it, especially considering how much I paid for it (shortly after it came out).
