Android DiskUsage – check your free space
What to do when the memory card or internal memory is full on you Android device? How to find the real nasty memory hogs? That’s what the following article is about.
A few days ago I was confronted with the fact that my memory card on my Galaxy S2 was full. Unfortunately, I could not imagine what would consume so much memory, yet I was willing to to clear something up on a venture.
So there had to be an app. As always, I prefered a free one. And here it is – Disk Usage – my find of the day.
With DiskUsage you can visualize which folder uses how much memory. So you get a quick overview of where the real “memory hogs” are.
After starting the app, you must first select which storage medium has to be analyzed. You have the choice between the internal (device) memory and/the SD card(s).
How to add speech recognition to any website with HTML5
Since Apple’s Siri voice recognition/voice control has again got back in focus of the crowd. But Siri is far from being the only working voice control solution. There were already a number implementations before, some good some bad, and there is still far more than just Siri.
How you can “install” a voice recognition into your website with just one line of code, is what I want to show you today. The whole thing is based on HTML5 and is established as an input element-tag.
And this is how it works:
<input type="text" x-webkit-speech />
Who wants to see the speech recognition in action, should go over there. The only downside of this solution is the fact, that this speech recognition is far from cross-browser compatible. So at the moment it’s only implemented in Google’s […]
News flash – the shop is opened!
It’s once againt time for a small update, so once again there is something new at this blog. At the top menu, a new item called “Shop” has been added. Yesterday I created an tiny aStore, that’s how Amazon calls its custom shops.
Therefore the products are not from me but from various retailers. The shop here in the blog is basically an selection of items from the Amazon range, handpicked by myself.
All products in the shop are either owned by myself, so that I can recommend them with a clear conscience or they’re products, which I think are worth to be recommend and relevant to one or more of my blog articles.
If you buy something, I get (on average) 5-10% commission of the selling price. With a purchase through the shop you can support me and […]
404Checkr – a fast and free bulk link checker
This article is dedicated once again to a small self-creation. So it’s about a little tool of mine, which I have created acouple of days ago, as in most cases, out of necessity. So I was recently looking for a opportunity to check a large list of links as easy as possible to identify the dead links out of it.
The initial situation
At least if you have to check 20 or more links for their validity by hand, you realize that ther must be a better and faster solution. Therefore I have written a small program in C#, which helps you to check as many links/urls as you like for their validity. I have named the tool “404Checkr”, whereby 404 refers to the HTTP statuscode 404, which says that a page/file could not be found.
What does the […]
Mastering OpenSSH – Part 3: How to secure login by using a key file
After we set up an OpenSSH server in the first part and completed the basic configuration to secure the server in the second part of this article series, we now want to configure the server to make use of a key file (hereinafter also “key”) for the login process.
The SSH key authentication is based on the principle of asymmetric encryption. So we need a key pair consisting of a public key and private key. The public key is then stored on the OpenSSH server and the private key goes to the client.
The top priority here is to keep the private key secret forever and in any case. If someone else comes into the possession of the private key, he or she can log on to your server.
As a small obstacle you can provide the private key itself with a password. But nevertheless, if the private key gets public or falls […]
