luos··on Hidden obstacles for self driving cars
I don't have a driver license so for me that would be perfect. I don't care about driving, I don't want to drive, but I want my (or a) car to come for me to the bar / after work. If the weather is not good then I will use public transport.

I think people overestimate their abilities. Sure, this is a new technology but in X years these cars will be better drivers than 99% of the people.

luos··on Google's driverless cars designed to exceed speed limit
Would these cars overtake others, for example if there is a car towing an other on a one lane (each way) road going significantly under the speed limit?
luos··on A Murder Suspect Asked Siri Where He Should Hide His Roommate
If you have an android and enabled some kind of feature by mistake (like me, I always say no for these but it has my location, even when I was abroad) you can see the log here:

luos··on JPG Internet
I had almost the same idea. Here there is something called facebook zero which is available at 0.facebook.com, it's facebook without images but it is free for T-Mobile users.

There would be a possibility to do some browsing if a user sends a query message to a page/other user-bot which then downloads the information and responds in a fb text message. Like that google sms feature.

Fortunately I have internet on my phone so this is not really a need anymore :)

luos··on OpenStreetMap Then and Now
I recently went abroad in Europe and because of the price of data roaming I decided to install the OsmAnd android app for navigation.

In Romania, Transylvania using instead of a map it was very good. Even the little dirt roads were there. I had three problems with the app. The navigation did not wanted to respect my setting for "prefer highways", we always tried to regenerate the route, "we are near, maybe now it will know". Seemed like it hated highways. The app felt very buggy, I know it is free, but froze a lot of times and has un-intuitive controls. For example if I wanted to add navigation to a target it sometimes used a location from yesterday or something totally unrelated. Asking a question "Do you want to keep the current route?" it sometimes keeps the current route, sometimes reverts back to a route before, sometimes even just shows where I was yesterday. Third is, searching is a PITA. Because a lot of house numbers are missing you can only input intersections, sometimes it works, sometimes not. Searching for POI-s is good (remember, it is offline), but a lot of things are missing. I found if I add favorites and want a route between them then that usually works. (I don't know how the app creators are related to OSM.)

Anyway, I recommend the app because it is valuable and usable if you don't have connection (and free if you use only 10 maps).

Recently I wanted to use a web based map in one of my project and I found it is very easy to use OSM with http://leafletjs.com/. It has some bugs (I couldn't get a "map loaded" event out of it, maybe it is just me) but overall I think it was easier to set up than a google map. The one thing I missed is the geocoding of addresses, it is not really reliable because of the missing house numbers, instead of OSM I used the google solution and they can work together flawlessly.

I am glad to see a free map solution gaining popularity. Where I live there are events for mapping. I think on Saturday there was an event for mapping accessible roads/buildings for disabled people and someone even added all the fire hydrants downtown.

luos··on Ubuntu Mate
What kind of scripts do you use?

I use xfce but I only use xrandr (not depends on xfce) to switch between monitors and don't really know what other scripts are useful or good to have. (or what can I achieve with scripting)

luos··on Dart 1.5
I tried dart just last week with dart IDE (1.4.3). It was good, much better than javascript.

My observations: Installing dependencies was easy. Types help a lot. The IDE is good but sometimes can not show the correct type or just shows dynamic, the autocomplete is usable if you write `this.` . Usable for a modify-refresh cycle but the attached chromium seems to be a little buggy (on xubuntu the window is not correctly drawn). In-browser exceptions are a little cryptic to read. Very similar syntax to java/c#. Good stdlib (I tried async/browser/math). Little cumbersome calling JS but it works. Bult-in factory pattern, setters/getters.

I think they could let users create multiline functions with the => operator (currently only one line). :)

I tried to pub my code, but it did not work for some reasons. I haven't tried since then so I don't know what kind of js it generates.

luos··on Ask HN: Who wants to be hired? (June 2014)
Location: Relocate to London from Budapest (EU citizen)

Stack: I am a PHP/JS developer (1.5+ years of working experience) but I want to move to Scala

Resume: on request

Contact: luosathn@gmail.com

If you are looking for a junior scala programmer in London I would gladly relocate. I am learning computer engineering at the Budapest University of Technology but I only finished the 90% of the BSc. I am a student now but I decided it would be better if I get some fresh air outside my home city.

In 2010 I worked 3 months as a "data management" intern in a bank. I did the intern things of looking things up in the bank's databases, learning about the systems, writing Oracle, MSSQL queries. From 2012 to the end 2013 I worked part and full time (when I had time besides the school) as a PHP developer at a small company. My task was to maintain and develop PHP and MySQL/MSSQL applications. But sometimes I had to tackle things like XSL.

In the meantime I started my own company to operate a family business, my work was to set up webshops, managing the hosting and small developments. We tried ourselves in the social buying hype too but it did not work out as planned. I usually used prestashop and joomla for these.

In late 2013 I decided to focus on school but I just could not get into the right mindset so I decided to try something new and try to relocate to London.

Last year I started working on a hobby scala-play project and I started to like the language. I think it is the most usable language I used (despite its quirks). I am managing the Linux VPS which this app runs on, so I am somewhat familiar with linux systems, my desktop is linux too. I tried several technologies like rails, node.js or laravel but these are just to improve my knowledge.

I am looking for a scala job opportunity mainly in the webdevelopment/distributed-systems part but I am interested in other type of jobs too. I am a webdeveloper but I really like solving IT Security problems (like the Stripe CTF) too.

I am currently living in Budapest so I need time to relocate. If the company could help in finding a room that would be good but if not, that is not a problem.

luos··on Facebook without the News Feed
I am using facebook like this for at least half a year with the News Feed Eradicator plugin. I don't really care about other people posts or jokes for the 2214 time. Sometimes I check it on my phone on the bus and it really just reinforces my decision to hide. And the best is that it's eradicates the possibility of mindless-endless scrolling. Overall, recommended. :)
luos··on Creative Cloud outage leaves Adobe users unable to work
Sadly Gimp doesn't really work. I tried to use it but always were differences when showing the psd. (Missing effects, bad colored layers, etc. )
luos··on Report: 44% of Twitter Accounts Have Never Sent a Tweet
In my country noone uses twitter I know. I only used it once to message Digital Ocean why are they so slow. It worked out better than I expected, they responded in 5 mins and I could see others with the same problem. Other than that I really don't know why would I use it. I think for me reddit multis are the perfect solution.
luos··on Drop Dropbox
There is tresorit ( https://tresorit.com/ ), but depending on what you want to do, they seem to be a little expensive.
luos··on There is a pure HTML Gmail, and it still works
I think it is because performance. Visit techcrunch (23) or huffingtonpost(30+) for example with an extension like ghostery which shows how many external js lib gets loaded. I don't block js but I block flash and it is for the same reason.

My record is around 40+.

I don't know why do they need that many. See reddit, loads 2 I think.

luos··on Scala – 1 Star – Would Not Program Again
It is not just about the trailing slashes.

I wanted to create pretty urls but I couldn't do it in a simple way because the developers thought that in a path can not be optional parts, like: /article/1/article-slug and /article/1

So they removed a useful feature. And it was in a 2.x -> 2.x+1 release... Yesterday it worked, today not. I was not happy. :)

http://stackoverflow.com/questions/14980952/routes-with-opti...

My othern concern with scala, what is mentioned in the article, is the operator usage.

How am I supposed to "invent" this <:< notation for adding headers? (dispatch lib) `val svc = url(object_url) <:< Map("User-Agent" -> "Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Win64; x64; Trident/5.0)")` or in squeryl, converting a boolean into a "query boolean": ``` val fls = false fls.~.? ```

Other than these, I like it. When I am coding in JS or PHP I always praise the scala types/ compile time checks. I am almost afraid of dynamic typing since I tried scala. :)

luos··on Ask HN: Do you use N + Enter to access Hacker News?
Yes, sadly. On my machine it is win+w - n + enter (new browser + hn ). If you don't want to waste your whole day on HN try the procrast settings in your profile. What works for me is every 70 minutes I get 10 minutes HN.

I started developing a site which domain starts with "news". Sometimes in some mysterious way that is the first. :)

luos··on DigitalOcean Sucks. Use DigitalOcean
I use smallest Digital Ocean package (Amsterdam) to run a play 2.x scala app. It is not a visited site (yet, heh) but I am very happy with it. And they gave me a coupon when I couldnt tinker with the project and cancelled, so I am back again :)

The sucks part fortunately havent affected me yet. I could use a little more ram but when I am there it could be changed with a click (and a reboot if I remember correctly).

luos··on Startup Idea: Solve Personal Analytics
I'm slowly creating something similar to learn rails.

I want to track how much spend, consume electricity or gas, what are my goals.

The problem I found that I forget to enter the data into the app so it is fairly sparse. I can only get meaningful data on a monthly base.

I imagined it would be capable to compare gas (heating) consumption with the weather on the same day but it is not really working (without some automatic data input, that I don't have).

Among others I though about adding mood tracking, attaching 1-3 picture/day so when you want to watch back on your vacation you are not overwhelmed with 5000 photos, tracking locations. I would like to think about it like a social network where I am alone or something like this. (Codename: Track My Sheet :-) )

Showing trends, adding watchers like "you now need 1 year 3 months on your Y Account to reach Z amount at your current rate +Q USD / day, but these kind of things are faster with an excel sheet. Here is a dashboard mockup: http://snag.gy/OozTi.jpg

It is similar to the reportr.io app, actually I started mine on the same week before I first saw it on HN. :-)

luos··on WebGL Terrain Flyover Demo
Did you install specific drivers for it? I'm using a Thinkpad T420 with xubuntu and i only got 12-13 fps in Chrome 24.0.1312.52.

edit: Ok, I figured it out, it's because I used an external 1920*y display, if I resize the window it gets faster.

luos··on Ask HN: Which hosting company to use for a small SaaS product?
AppFog has a free tier under 2GB Ram, 50 GB bandwith and 100 Mb database.

I think it's not the cheapest but it gives you some time before you have to invest. I didn't used it in production, but for testing it was good enough. I could deploy a scala-lift app in a not too hard way. (1 GB ram, 2-3 hours thinking and one af push, but I was not familiar with lift or clouds at all)

There is a class on coursera going about scientific writing if anyone interested:

luos··on Apple's poisonous touch silently kills the GNOMEs of the Linux forest
I use gnome because my computer can't run unity. :)

I didn't wanted to change to other desktop because as it always happens to me, something goes wrong and i can't use my system for half a day. (Today i'm upgrading to 11.10, the support term is over for .04, I hope it goes well...)

luos··on A life less posted
"it definitely indicates something that person has to deal with"

I don't agree. On facebook you see idealized lives of others and it can be pretty depressing. You see others going on vacation but you don't see them fighting with relatives ( ok, I see that, it just annoys me) and you can start thinking that their lives are better than yours.

I don't know if this is an accurate source, but I think this can be a problem for not so (mentally) stable people: (They could suffer from this without facebook too, but the dose on facebook is much bigger than in a close friend circle.)

luos··on A Node.js speed dilemma: AJAX or Socket.IO?
"AJAX is usually faster than Socket.IO to “code”..."

I tried node.js and some modules a couple of weeks ago. It was pretty easy to set up and I had a "working" chat application in few hours with socket.io. It was 20-30 lines of code, provided callback to send data immediately to other clients.

I don't think polling the server every 500 ms is a good practice, say 5-10 sec or more can be reasonable, but with socket.io you got it instant.

luos··on Is it OK to hold credit card numbers in cookies, Santander?
I dont know either why is this the default in rails. In PHP you only have a session id in a cookie. When I first saw how it works in rails (ruby?) it blew my mind.

I don't want to think about how many rails user don't know this and send sensitive data to the client.
