I'm an engineer and have worked in medical imaging for my entire career (20+ years) writing software to transport, analyze and report on images from MR, CT and X-ray systems. I originally did a PhD in computer vision and jumped into medical imaging, first as a post doc at University but I've since worked in the pharma industry and in the last 10 years at medical imaging startups.

It's a fantastic intersection of software development, pattern recognition and algorithmic development in a space that gives your work definite meaning - spending your days looking at images of people with cancer, osteoporosis, arthritis, lung disease etc can help focus you on the MVP that matters. You learn some radiology as you go too; I'm pretty good at KL scoring for OA on hip and knee radiographs for example.

Development in this space can also have it's frustrations, having to combine the latest innovations with the need to meet FDA and European regulatory requirements requires a little lateral thinking sometimes. Historically there was a reluctance in the field to adopt newer technologies but in the last 5-10 years that has really started to change with a lot of imaging moving into the cloud and the regulators waking up to fact that software isn't built like a syringe!
Elixir – Building a Simple Api
Note that this is on an ancient Kindle without a touch screen. I have a Kindle Paperwhite and it most certainly does CSS and JavaScript. It's slow as hell and scrolling on an e-ink display is very painful due to the time it takes to refresh the screen (especially because scrolling is done by dragging, like on an iPad, but there is no visual feedback – it would be much better if there was a "page down" control).
You can guesstimate these things a bit by the Kurzweil type technique of projecting Moore's laws type improvements in computation and comparing them to animal neural systems as in one of his graphs:

Ask HN: I have 9 months to build a strong portfolio. Any suggestion?
I have until the end of the year to build a portofolio to demonstrate my skills in the following frameworks/technologies/languages: AngularJS, ReactJS, RoR, Python, Go, Scala, Clojure, Android and iOS dev; and I seriously lack project ideas.

Do you have any suggestion?

I will take anything (web app, mobile app, programmer productivity tool, game, small interpreter/compiler, ...) provided it can be done in a small timespan (1-2 months), is challenging and will let me dig deeper in the technologies listed above.
It runs through a custom HTML/JS client over web sockets with a video codec designed to be decoded with low CPU overhead [1], or a native client [2] for better performance, especially with game streaming.

For anyone interested in the space, we also have https://x.io which wraps our streaming tech up with a bunch of other stuff to make running an app as easy as making an API call.

> what good are they?

People might reply that most management is, in fact, not good, or at least contributes no better than random chance.

Be careful about questioning the need for management, that way lies anarchy - literally! http://en.wikipedia.org/wiki/Mondragon_Corporation

I don't believe Holacracy is striving for anything like that. I think it's yet another faddish management theory with buzzwords to keep people - who would otherwise contemplate the uselessness of their existence - busy at large bureaucratic companies, much like the tides of reorganization and the rigors of standards compliance and change management do.
I don't have a Voyage yet (will probably upgrade the next time I'm in the US), but I mostly agree that each device has been a small but good upgrade. I do dislike that they removed the physical buttons, and the first version where they did that was a bit of a pain, but you get used to it.

The Paperwhite screen is just fine for me, and the justification problems the poster refers to have only been annoying to me a few times - the free public domain books are often not converted decently, and side-loaded books aren't always formatted nicely. Other than that, no problems here.
I thinks these articles are exaggerating a situation which could have been a simple defamation lawsuit.

That's almost right. It should display the last page read!
Clickity Click - http://www.lucolo.com/

Advice

- You mention what Lucolo does not do - but it is not clear what it does do, o make it a viable email alternative. No mention of any features either.

- If you are not comfortable providing screenshots, a simple mockup would do as well. This works wonderfully on conversion rate (in your case visitor to email capture)

- Have an "about" page on the website, that gives us some information on who you are and why we should trust you with our email addresses.

All the very best!
I love the virtual bookshelf concept. I love not to waste time wandering through libraries and that almost any book is two clicks away from me.

That said, I'm also a graphic designer and many book layouts are awful. I can't tell how many times I read 1 star reviews of good books which were worthless as an ebook.

The ebook is thrashing 500 years of typographic tradition. It's trashing everything we know about making a good reading experience. This is not only insulting, but insightful. Amazon is telling his costumers:

"We are a GOOD ENOUGH company. We are not striving for excellence."

OT: I've recently tried Audible as well. I felt dirty and cheated on. I gave a chance to Amazon Kindle, but I'll never compromise with Audible's business tactics.
Maybe you ought to keep reading through 632.6 and 632.7. Once you've read those, keep reading the entire thing plus the body of case law which explores these concepts and their practical applications. You're really doing yourself no favors arguing from ignorance and expecting others to do the research you're apparently too entitled to do yourself.
I don't get it, so this is a video player app that's built on a browser which then just uses the same thing my actual video player does?

What does making software fast mean?
Along with building customer engagement it is important to build a brand. The brand becomes a gateway to other services like certification, training and consulting.

For an open source OEM, a brand is obvious, but for a community player, it is not so intuitive. The brand is built by focusing on contribution, good writing (blogs, articles etc) and showing visibility on the forum. Like the OP mentioned, you cannot be too invested in the IP as a non-core player.

It's not quite the same thing, but X.IO [1] from OTOY does a lot of the things mentioned, and can even run Steam directly without having to use in-home streaming (and we can take advantage of things like NvFBC to cut down capture time).

Going that method you lose the price advantage you'd get with the spot market, but a lot of the underlying complexity is removed.

TV5MONDE – A (tentative) technical analysis
A few months ago I was trying to remember the name of this game. It took me over an hour of searching, but I eventually found it. It's called IMPETUS. Here is a post-portem on the author's site [1], and the original Ludum Dare post [2].

The two games are a little different, but they're similar. In Impetus, everybody cooperates to continue pressing the button, but you can press it as often as you like. There's no per-user tracking or anything like that. Also the timer was 10 seconds instead of 60. It lasted under 12 hours.

Microsoft would never say for sure.

And you're discounting company-internal products that were built in the 95-98 era, then updated when new business regulations came out, but were never rewritten in a modern language and the company wouldn't spend time and money to port them to Windows 9 when they worked fine on every previous version -- they'll just wait until a newer version of Windows fixes the problem or Microsoft very forcibly drop support for 8 completely.

I ran those sites through the Sitetruth.com business legitimacy checker. The results are amusing.

hillaryclinton.com - no street address on web site. SSL cert is domain control only validated. Known to Open Directory, so it gets a medium rating of a yellow circle.

tedcruz.org - the robots.txt file redirects to the robots.txt file at "www.tedcruz.org". We interpret this as "robots go away", which is perhaps too strict. The SSL cert is domain control only validated. The site is known to Open Directory as non-commercial, so it gets the grey non-commercial neutral rating.

marcorubio.com - the robots.txt file redirects to the main page, which was interpreted as "robots go away". The SSL cert is one of the low-end Cloudflare certs with a long list of unrelated domains, so that's useless. Known to Open Directory from an old Senate campaign, and Open Directory says it's non-commercial, so it gets the grey non-commercial neutral rating.

randpaul.com - no street address on web site. SSL cert is domain control only validated. Not in Open Directory. No way to validate site ownership, so it gets the red do-not-enter symbol.

Paul's US Senate site, "www.paul.senate.gov", is much better. The U.S. Senate has a good Organization Validated SSL cert with full address info. (Our address parser couldn't parse "The Capitol" as a street address, so there's no map.) Amusingly, the SSL cert covers the sites of a number of senators of both parties. That site gets a green checkmark.

There's also "jebbushforpresident.com" and "jebbushforpresident.net". Both are bogus sites, not from the candidate. No street address, bad SSL certs, not in Open Directory. They get red "do not enter" symbols.

Not one of the candidate sites has a street address, or an SSL cert better than the low end "domain control only" validated certs. None of them except the U.S. Senate site match anything in our business directories, but one would not expect that for sites like these. The SiteTruth engine did properly identify the fake Jeb Bush sites as less than legitimate.

My biggest gripe with Voyage is the silly restriction to 4GB and no SD card in order to make PDF viewing far less likely. A lot of scientific papers are available in PDF only as well as older books and magazines and they are considerably larger than Kindle's own format yet preserving layout nicely, so they are my preferred media. I don't care about uneven lighting (yellow-blue cast across the screen) as I turn the light completely off.

Is there any e-reader with "retina"-style e-ink that is optimized for viewing PDFs/PostScript and allowing a SD card?
We will correct this. Thank you!
Were there specific reasons in choosing atom-shell rather than eg. nw.js?

I think he has some valid points in his rant, although I must say I enjoyed my Paperwhite 1st Gen very much and I don't find those issues (especially on the justification and font choices) to be a blocker for me from enjoying the books.

As Linux advocate myself, I was surprised to see Stack overflow's statistics[1] showing Linux being on par with OSX among the SO user-base. That was honestly more than I expected.

Where I live, I mostly see Lenovo's or Dell's running Windows. There has been an increase in Macbooks but it's nowhere near the norm.

Linux of any kind however... I've seen maybe two times in a corporate setting or at the developer conferences I've attended the last two years.

Where I work, I literally feel like the only guy at all running Linux. There's clearly huge geographical variations at play here.

I live in Japan and my wife is Japanese. Also, I had this conversation with several Japanese people.

I can tell you that most Japanese I know hate the concept of tipping and it makes them uncomfortable. They also hate giving tips. Not because of the money, but because they think that tipping is a way of looking down the other person.

Of course, when I say offensive I don't mean that they will curse and hate you forever. But probably some will think: "I already have a salary, I don't need you give me your coins".

If there's an scale of socially awkward situations, I guess tipping would be slightly under asking ketchup for your sashimi. But definitely not as bad as going into someone's house with your shoes on.

Ask HN: Startup failing due to lack of business acumen, what can I salvage?
Hey folks,

I cofounded a startup that makes a point of sale app a few years back, and we've made nearly every mistake in the book. Hiring friends for key positions, never took any investment money or sought any out consistently, had cofounder drama, second system syndrome.

I'm the tech lead, and our product's fundamentals are strong. We're a solid alternative in our marketplace, even with two years development spent on a second system that was thrown away.

This time around, we've taken one punch too many. My current business partner pitched another company on providing us capital for referrals we can offer them, and drew up what looked like a realistic plan. That plan looks like it has quickly fallen apart, due to him not accounting for any debt service in our expense projections, as well as overestimating our ability to hire and train replacements as our sales department churned. Sales through last month were consistently 25-30 licenses of enterprise software, priced in the $1000s, and now we have approximately 2 in the first half of April, two weeks into replacing our sales staff that had us between 25-30 sales for 5 months. The other company's initial payment that was intended to fund operations as we pivoted from a high license fee model to a monthly fee model, was instead spent on emergency debt service.

I'm at a loss because I'm at the end of my rope psychologically. I don't have the energy to spend yet another year keeping the company's head above water. At this point, I'd rather move on. Ideally, I'd find a buyer who will take on the company and give it the love it deserves: I found out late last year that our cost per acquisition from Facebook ads was roughly $100 for a software license worth around $1000, so there's a great business here. There just needs to be someone who can take charge of it, and fund it. How in the world would I even find that?
Why not write the news article when the hotel has actually opened? Otherwise it just sounds to vaporware.
I don't know much javascript, but that looks extremely error prone to me. How would it behave in different monitor sizes? With zoomed in/out screens? On mobiles, tablets, etc?

And it would still be pretty easy for a cheating script to work cheat your validation!

So do you feel the pitfalls of probabilistic programming / Bayesian data analysis are potentially more severe than those of traditional methods?

I don't get to use that much Bayesian analysis in my work, but I've been toying around with a hierarchical model of content popularity recently: are some topics / authors / genres more popular than others? Frankly finding it hard to separate the signal ("this is what people actually like to read") from the noise ("this is what just happened to be trending and will not be reproducible").
The Intel chips (Xeon E3-1285L v3 - Haswell and Atom C2750 - Avoton) are both built on 22 nm. The Power 8 processor is using the same process size as the Intel parts, 22 nm. The ARM 64-bit Applied Micro X-Gene 1 SoC tested is on 40 nm. X-Gene 2 is on 28 nm and X-Gene 3 will be build using a 16 nm process. X-Gene 2 is apparently sampling now but we didn't get access to it yet, nor have we seen any publicly available platform using it. Once we'll get access (which should happen soon) to Xeon-D (Broadwell-DE) using a 14 nm process size, the results will be added to the repository at http://lvalsan.web.cern.ch/lvalsan/processor_benchmarking/

I do not use mock objects when building my application,
and I do not see the sense in using mock objects when testing.
If I am going to deliver a real object to my customer
then I want to test that real object and not a reasonable facsimile

This reveals a fundamental misunderstanding of the purpose of mocking.

If I test object A (and mock B for this purpose), I'm testing A - not the mock.

Another test verifies behavior of concrete object B (while mocking A).

Mocks themselves are not what is being tested.

Of course it is possible that both A and B behave correctly in isolation (measured against expectations defined by unit tests), but they don't integrate well.

In other words, expectations, assumptions verified by both unit test suites do not cover everything that's actually required for the components to form a functional system - there is a "gap".

This is however not a flaw of Dependency Injection, but a natural shortcoming of unit tests as such. Obviously they are not a replacement for integration tests - but that works both ways. Different beasts.

The advantage that unit tests have over integration tests is that they make it much easier to pinpoint sources of failures.
That's been huge for me as well. Speaking at conferences and writing my book over the past year has been a great entrance in to getting business. It's really paying dividends.

Plus, the article gets it wrong: the Paperwhite screen isn't backlit, the leds are oriented perpendicularly from the reading angle, so there is no direct light shining your eyes. Add that to the automatic dimming, the Paperwhite isn't going to keep you awake.

As an anecdote, I am immensely susceptible to falling asleep when reading in the dark with the Paperwhite.

The only place I've ever seem Illumos mentioned is in the ZFS community as a OS where ZFS is fully supported and fully integrated.

It seems like the majority of the ZFS crowd prefers running FreeNAS, NAS4Free or ZOL instead. So the only place I've ever seen Illumos mentioned, it still seems like a niché product.

I just tried out SelfControl.app, and it's actually really effective! If you edit /etc/hosts while it's running, it replaces the entries immediately. And somehow I couldn't get any blocked websites to load even after quitting the app and then editing /etc/hosts. I'm not sure how it's doing it, but to be honest, it would be far less effective if I figured it out!

EDIT: I couldn't help myself :/ Turns out that it also adds some ipfw rules: http://www.joshuakehn.com/2010/10/25/Defeating-SelfControl.h...
"Doing things that don't scale" is great advice for people whose first inclination is to automate everything with code, and not do 'people' stuff.

Ultimately, though, you've got to be able to work "on" the business, and not in it, as they say. And that means doing things that "scale" in some sense. If you aim to keep the business small, it means doing things that let you remove yourself from the day-to-day operations of the company.
