luka-birsa··on Airbnb gets into the property management business
I Love the idea behind Airbnb, but I hate what they are doing recently. They are deregulating the market and making it worse for everybody except the tourists.

Thanks to them it will be harder for you to rent or buy a place to live. At the same time they are putting registered businesses out of business thanks to the marketing of "sharing" economy, which is a huge sham (see Uber).

I hope that countries protect the regular Joe's living in cities and demand payment for professional renting services, just like any regular apartement / hotel.

Thanks for ruining it for everybody else, so you can make a boatload of money.

luka-birsa··on Google Takes on Uber with New Ride-Share Service
Love it how Uber is getting Ubered by providing a service they were supposedly providing but it was only a marketing scam to get around Taxi regulation.

This is proper "sharing economy" where the other party isn't doing this to make a living out of it. I wonder who will Airbnb the Airbnb and is that at all possible.

The end will be the same anyways - both companies are competing for a spot on the customers mobile phone so that they could provide a service when autonomous cars are up and running.

luka-birsa··on Uber Loses at Least $1.2B in First Half of 2016
I'd also add that the proof is in the whole "let's create autonomous cars and drive people around without drivers", where it's kinda obvious that it can't be a sharing economy if they provide the car and the driver is not needed.
luka-birsa··on Uber Loses at Least $1.2B in First Half of 2016
I'd say that Uber is more a taxi company than a car sharing company as people buy dedicated cars to provide service and earn a living. I'd go as far as to say it's a first trully global Taxi company with a very good app and payment implementation.

The whole car sharing is marketing bull, so that they can justify dodging regulation and dumping prices.

luka-birsa··on How to Set Up and Deploy to a 1000-Node Docker Swarm
Fully agree, this is a typical example of a shitty Swarm/Kubernetes/etc blog post, which gives no real substance - this stuff is covered in first 5 minutes.

We are just deploying our first Kubernetes cluster in production and anything more than basic hello world would be welcome. Like how to configure networking in production, how to route traffic to containers, how to provide volume storage (backups, etc..).

I mean, we'll get there of course, but we opted against Swarm as data is even more lacking than Kubernetes.

luka-birsa··on E-paper is making it's way into museums
Sure, you can use HTML&JS to create an interactive E-Paper device with the technology that Visionect offers - check the development kits: https://www.visionect.com/development_kits
luka-birsa··on E-paper is making it's way into museums
You'll need to wait for E Ink to launch 24" displays :).
luka-birsa··on E-paper is making it's way into museums
You can check https://joanassistant.com which is a room booking system, based on the same technology. It integrates with Exchange, Office 365 and Google Apps, connects via WiFi and runs for months on single battery charge. Its fully interactive and updates instantly.

We're changing that and helping E Ink to break through into digital signage and there's actually a lot happening in this segment.

You have bus stops, buses, traffic signs, museum labels, room booking signage, smart digital prices, buildings, queueing systems, outdoor ad panels,...

Check our blog for some examples: http://blog.visionect.com

luka-birsa··on E-ink wifi display project
Access to panels is possible, you just need to find the right distributor. But getting the display is just a small part of the story. You need to build your driving electronics and figure out how to drive the display. 3-4 inches are also usually much simpler to drive, you can use a TCON and there's no waveform management, etc...

The fact that this is much harder than it seems (hardware is non-mainstream, access to documentation is limited, support is very hard to get, displays need special driving chips) actually prompted us to provide a development platform for E Ink. It took us years to figure everything out and for somebody wanting to prototype something this is a show stopper.

As far as pricing goes, the 6" panels are priced approachable, while the large displays still need to hit the mass production price points. Obviously if you buy from us in bulk we can provide you much better pricing than a price for a development kit, but E Ink is not cheap.

luka-birsa··on E-ink wifi display project
We tried that previously, but it didn't work out. People that want a cheap version, still complained about the price and suggested a hacked Amazon Kindle as a viable alternative.

Refresh rate: ~750 ms for 4 bit and up to ~125 ms for 1 bit

Videos of device in action: https://www.visionect.com/blog/kindle-users-can-your-reader-... (our previous generation device)

High prices are driven due to price of screens and the amount of support we provide. It's a development kit, intended for customers building products. We're not that much of DIY (like a hacked Kindle or the OPs solution), but rather a production ready solution that you can use to prototype and later deploy in field. Examples [1], [2], [3]:

You could try using our development kit [1] which is a production ready version of OPs system.

You can already get color e-Ink screens and not only that - they are super large (32"). Currently they are still priced a bit steep but the prices will drop. We provide development kits [1] if you want to try and build any of the applications you have in mind.

luka-birsa··on E-ink wifi display project
You can. As mentioned in other comments we provide a development platform for E Ink displays that comes with open API and the ability to quickly hack together stuff using HTML.

We support WiFi, 3G and Ethernet and you can get sizes from 6" - 32". Check out our online docs [1].

I'm very impressed that you managed to create a nice DIY replica of our development kit. https://www.visionect.com/development_kits

We do the same in our Visionect Platform - a server component streams images to a WiFi, 3G or ETH enabled E-Ink device. We do sizes from 6" (proper device in casing) to 32" (in color as well).

luka-birsa··on Blue Ocean: a new user experience for Jenkins
Integrate into Gitlab, so we do not require a secondary Service. :)
luka-birsa··on Blue Ocean: a new user experience for Jenkins
We're running both GitlabCI and Jenkins (different teams) inhouse. Gitlab really upped their Game with the integrated Docker repo (we've adopted Docker heavily) but it is lacking the plugin ecosystem of Jenkins.

Jenkins on the other hand just feels dated. The new ui is very welcome.

Looks like we're going to keep the dual approach for a while until things crystallize further.

luka-birsa··on Scaling to 100M: MySQL Is a Better NoSQL
We've drank the NoSQL coolaid mostly as we prefered a schemaless approach to our database and couchdb looked like a cool thing to use. Tested, deployed in production abd after a while we figured out that most of the promises about performance, stability, etc we're mostly bull.

HStore was released, we've migrated to PG and we can't be happier. Zero issues so far.

luka-birsa··on PaperLike: 13.3″ E Ink Monitor by Dasung Tech
We offer a bunch of E-Ink digital singnage solutions which can be used as a photo frame for the wall in sizes between 9.7" and 32". Check out http://www.visionect.com/technology/
luka-birsa··on Get Your Development Team Started With Go
Sure.

But since the post was on topic of Go and we do have quite large Go infrastructure I just wanted to comment that Go is awesome. More people should know about the awesomeness and perhaps experience the same as we did.

luka-birsa··on Get Your Development Team Started With Go
Probably true. But it would take us longer, code base would be larger and still harder to maintain and more error prone compared to Go.

It's a very old project and super important core technology - we did refactors before and I was somewhat scepitcal when lead devs on the project suggested to use Go instead for the next "refactor". I was blown away by the quality, speed and productivity.

If you're building server infrastructure that needs to be performant, consider Go.

luka-birsa··on Get Your Development Team Started With Go
Go Lang was a huge win for us in our server infrastructure. All high performant but hard to maintain C stuff got migrated to Go in 6 months and we never looked back. Code is much more managable, less debugging for memory management, much more readable and shorter by 60%. All that at negligable performance penalties.

For us its a freaking story of awesome success. Go = ROCKS!

Not as the default DIY kit, but there are other sizes we can support with the same electronics (basically all screens from E Ink and Plastic Logic). Also keep in mind that sizes other than 6" and 9.7" aren't mass produced, which means higher prices - there's a reason why Sony is selling their 13" PDF reader for 1k EUR.
luka-birsa··on How my school rejected an app made for students
I agree.

If I'm not mistaken, Google got sued for providing short excerpts of news from various news outlets and decided to settle out of court.

luka-birsa··on How my school rejected an app made for students
I'm not certain that linking and providing access is the same. Let's take a copyrighted work which we can relate to more easily than web pages - TV Shows on Hulu.

Now, you can always link to Hulu in your browser and direct your visitors to Hulu. Hulu as the (C) holder can then decide if you're geographically suitable to recieve this content.

How about building a proxy webpage that provides access to Hulu (let's call it EU-Hulu)? We'll build a complete Hulu clone that works in EU by tunneling video streams via VPN to our page and stream them from our web video players.

I don't think that adding attribuition (ie providing a "THIS CONTENT IS FROM HULU" and their logo) to the page would solve our legal problems. If anybody can confirm that this is in fact legal, I know what I'll be developing in the near future: EU-HULU, EU-Spotify, EU-...

Copyright law is very very very strict. If it's not explicitely stated it's forbidden. Even by taking code from a pastie repository, where it's clearly made public, you're braking the authors Copyright unless he specifies Licensing terms that allows you to copy paste it into your app. Source code for all closed source software could be made public and that doesn't mean you're allowed to use it in any way.

To go even further - Hulu, while it openly shares video content to US citizens is unavailable to the rest of the world. We all know that you can bypass the limitation by employing VPN, but you're breaking the Copyright law nontheless. It's their choice if they want to limit access to their copyrighted materials.

If OP built a Web browser clone, he would be in the clear. He instead took data from the webpage, mangled it into his own app and sold it for 0.99$. Now while I do not agree with the tactics employed by the school (they should embrace it instead), image we would be talking about Wikipedia and 6.99$ BestEncyclopedia app, developed by Apple, which downloads the data and presents it a very nice way (they'd call it Cylopedia-Flow with huge images and Helvetica all the way).

Right now you'd be very pissed at Apple.

I was hoping there will be a discussion bellow ideas hence the tag, to distinguish between discussions and ideas.
luka-birsa··on The Open-office Trap
Couldn't agree more. Open offices, while fancy looking, sport apalling usability. After moving into ours we had super issues with the team adapting to the noises and layout. Things got better only after most of the people started using headphones.

Separate office with a closed door = productivity boon.

luka-birsa··on Ask HN: I am a good developer but have a serious gaming addiction
I'm guessing a lot of us lack self-control when it comes to working from home. Too many distractions - for you it's games, for me it's the internet, for others chatting with friends.

The only thing that kind-of works for me is a complete change of setting - when I'm at home I never plan to do any work. All work has to be done in a designated place.

I started this in my colleage years, where I had a serious issue with distractions (like spending 3 months playing DeusEx from 7AM to 2AM) when I should be studying. I solved this by going to the Library and studying there. Sure its a hassle, moving to a secondary location, sure you need to figure out what you need to work there, but it was worth it. You just need to make sure that if you get an urge to game/surf the net/etc.. you get out of there. Sooner or later you'll get trained to automatically start working at the locaiton.

I have a similar setup with my current job - all work needs to be done in the office and the only work I do at home is the stuff that really needs to be done (I'm a cofounder, so it's easier :)). If I were to start all over again, then the first order of business would be to get myself a desk or an office - without that, regardless of how badly I want to do something, I'd be lost.

PS: An additional improvement in an environment is to condition yourself to work with music on your headphones. I started listening to music on my in-ear headphones due to the open-floor nature of the office and it really boosted my productivity (less distractions).

As a side-effect now headphones invoke a Pavlov-reflex, whenever I put them in my ears (sometimes even without anything playing) I start working harder and with more focus. It's also a curse - last time I needed to hack something (with maximum concentration) and found myself franticly searching for my headphones. Before finding them at last, I actually contemplated buying a new set right away.

BTW: We do have a team of people working in our offices and we did outsource quite a lot of stuff out. We found it that it's very common for people to get distracted when working from home and the tasks (even when properly planned) don't get executed. Now we actually prefer to have the outsourcers work in our offices if possible or we demand very hard penalties for missing deadlines (and they still do it!).

Don't feel bad - what you're experiencing is the norm.
