MySQL Replication on Mac OS X

Last week I finally had the time to take care of a backup server and set up a database backup scheme. I chose to use the built-in MySQL replication tools since I do not have to replicate between different database brands. I described the steps it took to get everything up-and-running in 'Setup MySQL Replication'.

Fit an Apple TV 1 with a brand new 160GB disk

After Googling for a day I finally found everything I needed to get my Apple TV 1 (with no disk) working with a brand new Samsung HM160HC PATA disk. The whole process is described in 'New disk in Apple TV1'.

E$-Library Manuals for AS/400 now online

Manuals for my E$-Modules and Functions for AS/400, iSeries or eServers are now online and searchable. I discovered a lot of typos and faulty descriptions in the old manuals, so the manuals included in the downloads have been removed. This way it is also easier to update them - and you can save them locally without my sidebar etc. by copying the contents and paste them into Pages or Word. Also, I added *SAVF files to the three major utilities still in use by me, which makes it installation on your iSeries a breeze.


I just edited the tag mv_timeMenu on tagSwap. Because copy/paste on tagSwap does something with line endings that makes much code end up all being on one line, I post the routine here too. Simply copy & paste.

  Creates a list of time values inside a <select></select>. Example:
  <select name="xyz" class="abc" id="def">
  [mv_timeMenu(-fromHour=800, -toHour=2300, -minutes=25, -selected=$db_value]
define_tag('mv_timeMenu', -optional='fromhour', -copy, -optional='tohour', -copy, -optional='minutes', -copy, -optional='selected', -copy, -optional='firstblank', -EncodeNone);
  local('result' = '', 'p' = 0, 'z' = 0, 'h' = 0, 'm' = 0, 'y' = 0, 'f' = false);

  if(! local_defined('firstblank'));
    local('firstblank' = 0);
  else(integer(#firstblank) <= 0);
    #firstblank = 0;
  #firstblank = integer(#firstblank);

  if(! local_defined('fromhour'));
    local('fromhour' = 0);
  else(integer(#fromhour) <= 0);
    #fromhour = 0;
  #fromhour = integer(#fromhour);

  if(! local_defined('tohour'));
    local('tohour' = 2359);
  else(integer(#tohour) <= 0 || integer(#tohour) >= 2400);
    #tohour = 2359;
  #tohour = integer(#tohour);

  if(! local_defined('minutes'));
    local('minutes' = 15);
  else(integer(#minutes) <= 0);
    #minutes = 15;
  #minutes = integer(#minutes);
    #result = '<option value="" ';
      if(#selected == '');
        #result += ' selected="selected"';
    #result += '></option>';
  // Calculate correct starting point
  #z = #fromhour;
  #h = integer(#z / 100);      // Take hours-part
  #m = #z - (#h * 100);      // Take minutes-part
  #y = integer(#m / #minutes);  // Calculate how many times the frequency fits

  // Calculate new minutes-starting-point
  if(#m == (#y * #minutes));
    #m = #y * #minutes;
    #m = (#y + 1) * #minutes;
  #y = integer(#m / 60);      // Calculate how many hours minutes-starting-point contains
  #h += #y;            // Add those hours to the hours-part
  #m -= (#y * 60);        // Subtract the hours from minutes-starting-point
  #z = (#h * 100) + #m;      // Construct new time

  #p = 0;
  #f = false;
  while(#z <= #tohour);
    #result += '<option value="' + mv_fmtnum(#z, '####', 'R') + '" ';
      if(!#f && #selected != '' && #selected >= #p && #selected <= #z);
        #result += ' selected="selected"';
        #f = true;
    #result += '>' + mv_fmtnum(#z, '##:##', 'R') + '</option>';

    #p = #z;        // Save previous time
    #h = integer(#z / 100);  // Take hours-part
    #m = #z - (#h * 100);  // Take minutes-part
    #m += #minutes;      // Add interval to the minutes to get total-minutes
    #y = integer(#m / 60);  // Calculate how many hours total-minutes contains
    #h += #y;        // Add those hours to the hours-part
    #m -= (#y * 60);    // Subtract the hours from total-minutes
    #z = (#h * 100) + #m;  // Construct new time

'Transfer services from server to server' mind map

Using mind maps to follow your thoughts and track your findings is really a superb experience, every time again. And especially MindMeister, because it is 'in the cloud', i.e. web-based and can be accessed from anywhere and almost anything.

Every one of my personal projects goes into MindMeister if it involves more than just a few scribbles. In this mind map, I have noted all steps I must take, with all peculiarities that arise in the process, to transfer web sites and services from one server to another, in this case from a virtual CentOS server to a co-located MacMini Server from 2011. Mind you, the MacMini Server is no toy anymore - it is blazing fast!

I find this mind map quite interesting and since I am not the only one in the world doing stuff like this, I thought I'd share it so you, reader, might find the information in it somehow useful.



Browsing the wines in our supermarket, I stumbled across a wine that really stood out: Slurp! Since I am always in to try something new, especially bio-/eco-wines and their statement on the label, I went for it. Well, a super wine! I can really recommend this one! The label is transparent and I used a blue background while scanning, so the text would be pleasantly readable. slurp
