ohwp··on The Russia Left Behind
Wow great pictures! Didn't have time to read the article but I had to look up the photographer: http://www.kostyukov.com/
ohwp··on How web browsers resize images
Some time ago I did a test for mobile screens. I used 64 color images at 2 times the size they had to be (for high-res displays).

High-res devices don't scale those images, but because the pixels are so small 64 color images are still looking good.

Related to this post: small displays will downscale the image to 50%. I noticed that most modern browsers use a nice reduction algorithm so the interpolation of 64 colors is also looking good.

ohwp··on WebStorm Tricks and Tips: Live webinar Thursday, October 24th
Same here. There are so much nice tools and shortcut to make your life easy! A very good return of investment for me.
ohwp··on Dropplets - A simple database-less CMS
A small rant: I think it is bad practice to hide content below the page height. I just wanted to close the website because I thought 'nothing to see here' before I accidentally scrolled and more content was revealed.
ohwp··on Firefox fixes save gigabytes of memory on image-heavy pages
Opera 12.16 kept it's memory around 330 MB (initial 270 MB).
ohwp··on Windows Phone doubles share in Europe, trails iPhone by only 1% in Germany
I've got the feeling the iPhone lost its cool here in the Netherlands. Suddenly the buzz is all about Nokia and HTC while Samsung and Apple are becoming less popular.

And I think I can understand why. The Nokia 520 is a great device for under € 170. And the HTC has a great screen, stereo sound and a very smooth designed Android version.

ohwp··on Researchers Develop Method for Getting High-Quality Photos from Crappy Lenses
This is not about reducing noise it is about fixing aberration and distortion.

So it even works on noisy images where you get a better quality image of the (still) noisy image.

They never mention that they extract details that aren't there. They just present details in a way that humans perceive as "sharper images".

You note about scanners is interesting. There once was a project that converted scanned disk record into MP3s. You had to scan the disk several times because of the scanners aberration (http://www.cs.huji.ac.il/~springer/DigitalNeedle/index.html).

ohwp··on Researchers Develop Method for Getting High-Quality Photos from Crappy Lenses
Nice! This is working better than I imagined. It's also smart they are using each channel separate since different wavelengths bend different.

And since this is a post action this could also be used as plugin for Photoshop, Gimp and others.

ohwp··on Your name is way too long for your ID
Since I read articles about this I just use a varchar-fields for 'name' in my databases. Never had any issues with names after that.

You can alway store name-elements as meta-fields as long as the original name is untouched.

ohwp··on Work like hell
A lot of people immediately start to talk about burnout. But it's important to understand that a burnout is not about working hours.

The fire burns out when no fuel is added. Fuel can come in many forms and shapes, like: working out, love what you do, gain energy from your work, eating healthy, sleeping well, and so on.

So the quote only applies to people who love what they are doing because they get there fuel from the job (which isn't a job for them but a way of living).

Question is ofcourse: why don't you do what you really love?

ohwp··on PhpMyAdmin Turns 15
I don't use PhpMyAdmin a lot, only when there is no other option available (I prefer SQLyog). But lately I got very frustrated by the interface changes.

Then I discovered the option to enable the old theme again. A great tool!

ohwp··on Glare from London 'fryscraper' blamed for melting cars
Had to think about the same Las Vegas building.

But the Vegas one even has a curve. So there is a potential lethal focal point.

ohwp··on Show HN - Client-side Google Analytics without using cookies
The rules also changed. Now it's enough to just show some text that you want to store cookies without obstructing the website.
ohwp··on Tell HN: Add ?share=1 to Quora URLs to display content without login
Looks like they totally closed the forum. There aren't any posts indexed by Google.
ohwp··on Tell HN: Add ?share=1 to Quora URLs to display content without login
Same with vBulletin™ boards.

Change

  showthread.php?1234-title
to

  printhread.php?t=1234
and suddenly you can read all the content (except for attachments) without login.
ohwp··on NSA finds Snowden hijacked officials’ logins
And this is one of the reasons why the argument 'got nothing to hide' doesn't count. When a hacker can access all this information it becomes easy to steal someones identity.
ohwp··on The consequences of living with a legacy PHP framework
Ofcourse there should be a better alternative at the time you tell your customers to move on. But no, they didn't run to competitors. I don't want to sound very arrogant, but when your work is good, customers will stay because they trust you.
ohwp··on The consequences of living with a legacy PHP framework
The company I work for also had this problem.

The solutions was in fact simple: we told our customers we wouldn't add any features or changes other than bugfixes. When you are telling the software is outdated and the support is gone they all understand it's time to move on [1].

Most of the time the customer also wants to get rid of the outdated website/webapp. So it's also a good reason to start something new.

[1] Ofcourse this doesn't work for all customers.

ohwp··on An attempt to create the highest resolution real-time map of global temperature
Real time means that a calculation ends before the next update. Real time doesn't say anything about rate but means there is a constant rate.
ohwp··on How one man turns annoying cold calls into cash
In the Netherlands we have a Don't Call Me List (https://www.bel-me-niet.nl/ (call-me-not)). When you subscribe to the list it's illegal for companies to call you (for advertisement). Works very well.
ohwp··on Ubuntu Edge: how many phones were really ordered - and the mistakes
Estimations are that Jolla is going to produce a batch of 50,000 units. http://techcrunch.com/2013/08/21/jolla-closes-first-pre-sale...

So I think it's strange Canonical didn't make this happen.

ohwp··on Apple seeks to trademark “startup” in Australia
At first I thought it was a joke. Then I read the article...

This is one of the reasons why I never buy something from Apple. I think they are bad for our creativity.

ohwp··on I Forgot My Phone
I started ignoring the people after there complete focus went to the phone. And they learn quick. Suddenly they realize they are behaving very anti social.
ohwp··on Life without a cell phone
I own a cell phone but never use it for the same reasons as you. Never missed it, never will.

This month a video went viral about the subject: http://www.youtube.com/watch?v=OINa46HeWg8 (I Forgot My Phone). So true.

ohwp··on Why I Hate Frameworks (2005)
Ofcourse the message here is 'too much abstraction'.

There are loads of bad frameworks that want to be too smart and too clean. I mean, there is nothing wrong with writing HTML. But I've seen stuff like:

   $output .= $framework->dom->returnInputElement('text', 'name', $initValue, $options);
That's nice and all but when it just returns the element without any extra functionality I think its just a waste of code and resources.
ohwp··on Defeated
Maybe even simpler: stay, don't fly.

The best solutions would be that all passengers refuse to take the scan.

ohwp··on Myth: Select * is Bad
SELECT * can be bad when you join other tables. For example:

  SELECT
      *
  FROM table1
  JOIN table2
      ON table2.field = table1.field
In the above example you select everything from both table1 and table2. When they contain fields with the same name, strange things can happen.

Therefore always use: SELECT table1.* FROM table1

ohwp··on Will we ever want to have sex with robots?
Cheating does not depend on physical or lifelike.

Cheating is when you say "I love you with all my heart" but in the mean time give your heart to other stuff.

ohwp··on I’m Thinking. Please. Be Quiet.
I'm going to be your neighbor! Just have to convince my wife.

But serious: I've got family living 1 km away from your place and they always notice cars passing by because it rarely happens.

ohwp··on I’m Thinking. Please. Be Quiet.
Tonight I woke up at 4 because it was totally quiet in the city. It's strange that we feel discomfort when things are quiet.

It shouldn't be that way and it's one of the big problems to be solved. Electric transportation can help. And maybe electric leaf blowers are the next thing Tesla should promote.
