1 min readI had the opportunity to install the e-learning package Moodle, and when I quickly ggged it, how to set up Moodle on Amazon EC2 was a hit. I thought that I had won because it was too detailed, but when I set it up, I created a mine clearance memo because it was filled with mines due to the Moodle version upgrade. 1. Set up Amazon Linux AMI 64bi please...
December 17, 2014 1 min readI recently switched from ubuntu to mac. Now you can develop unlimited iPhone apps! (Lie: However, even though it is the same unix-derived OS, there are some differences.) What I am most concerned about is that it is basically an app and a window. As someone who wants to generate a lot of virtual desktops and set up terminals here and there, this specification doesn't really fit in. ...
December 4, 2014 1 min readWhen I upgraded MySQL to version 5.6, I was in trouble because some queries were slow. As a result of a lot of ggg, the information that hit is as follows. character\_set\_connection = sjis and DATETIME columns are not indexed http://bugs.mysql.com/bug.php?id=74449...
June 11, 2014 2 min readThis is Google Glass Report Part 2. Last time I borrowed it, but this time I bought Google Glass Explorer Edition Ver 2.0 and reviewed it. Amazing! The representative is cool!! First of all, about the difference between the ver1 I borrowed and this ver2. Even if you gg, you won't get clear information. Google Glass 2 offers minor but important...
June 2, 2014 2 min readThe rumored Google Glass. It's already quite readily available in the US. But I can't buy it in Japan. Why can't I buy it! Does it mean that you should ask a parallel importer with risk? No, it's impossible. But those who have it have it. Early...
March 14, 2014 1 min readI don't know how to upload the extension file. See the Devleloper Console help _Note: Currently, due to the limitations of the new Google Play Developer Console, you can't add extension files to the first APK file you upload a new app. To avoid this problem, you can first upload only the APK file and add the extension file if necessary...
March 14, 2014 2 min readI was living a comfortable Git life with TortoiseGit and GitHub, but one day I suddenly couldn't pull. It seems that communication with GitHub via port 22 is no longer possible. Why? Speaking of number 22, it is an SSH port. I'm also sshing servers on AWS, so I can't think it's closed somewhere in the company's network. I wonder if they were banned from GitHub? ...

It's so ruthless that it passes through the catch clause. The fact that this exception occurs means that the manifest and the code do not match, so the code should be corrected! ...

March 13, 2013 1 min readDo not reuse passwords. The password must be at least a certain number of characters. Passwords must be changed regularly... It's impossible to remember that! So, I will publish a password management app that I created for the company. There are already a lot of password managers on Google Play, but the reason we didn't adopt them is - many of them ask for unnecessary permissions (for internal use)...
February 4, 2013 2 min readEven if you have a debacher and can perform steps, you can't let go of the ease of debackloging. In the case of Android, you can use the standard Log class to achieve that goal, but many people would be happy if the Tag had the class name, method name, and line number in it! When I thought about it, there was a person who realized it. For some reason, I tried to classify this so that it can be used. \[code lang="java"...
January 30, 2013 1 min readPhone numbers are structured with two hyphens, such as \[area code] - \[area code] - \[customer number], but this is surprisingly difficult to put a hyphen in a number that does not have a hyphen, such as 0312345678. Sometimes the area code is 2 digits, sometimes 3 digits, sometimes 4 digits, and mobile phones are 3 digits, so it's too much to do on your own. Wikipedia's area code section...
