Was time for a review of Header and Footer, the plugin many of you use to inject codes in the head, footer and middle of the posts and pages. The most common injections are: Google Analytics, specially with customizations Facebook Pixel AdSense Verification metatags The new version removes the Open Graph minimal support since that […]

Use get_option() Only Once, As Late As Possible and Store It
I see many plugins to get their options (one or more) with the super useful get_option() of WordPress not only once but every time they needed it and sometime more than once inside the same function. This is definitively not good for performances. Let me explain why. Admitting your options are “autoloaded”, your get_option() does […]
Clean Up WordPress User Meta Data Table
During a maintenance of a blog, I needed to clean up the user metadata table since many users was deleted from the main user table (wp_users) with a direct query. The quick and dirty solution is to run a “left join delete”. Here the SQL statement:
|
1 |
DELETE wp_usermeta FROM wp_usermeta LEFT JOIN wp_users ON wp_usermeta.user_id=wp_users.id WHERE wp_users.id IS NULL |
Easy and really quick (please avoid to clean […]
Akismet Optimization
I started a war again the resource wasting on Periodo Fertile. That blog counts an important number of pageviews and even if the server has a lot of power it was suffering. But that sound strange to me since with the same visitor load, months ago the server was not so overloaded. Why? WHY? A […]

MD5 in Java Compatible With PHP md5() Function
The request was to have a Java function generating the same MD5 string generated by PHP when using the md5() function. Here the code snippet:
|
1 2 3 4 5 6 7 |
MessageDigest md = MessageDigest.getInstance("MD5"); md.update(value.getBytes("UTF-8")); BigInteger hash = new BigInteger(1, md.digest()); String result = hash.toString(16); if ((result.length() % 2) != 0) { result = "0" + result; } |
Please, note the check on the “toString()” result which must be padded with a zero if needed. Have a nice hashing!
MD5 in SQLServer 2005+ Compatible With PHP md5() Function
The request was: replace the clear password on a big account database with its MD5 version as a string like the one we get with the md5() PHP function. There are a lot of suggestions on Stack Overflow, but many of them work only with SQLServer 2008 or greater version. Of course before to understand […]
