| .: Add node to MongoDB cluster To add a new node to an existing MongoDB cluster, login to the mongo shell on the primary node and run the following command: rs.add({host:"mongodb3.example.net:27017"})
Similar to remove a node from the cluster, use: rs.remove("mongodb3.example.net:27017")

| .: Custom nginx error pages For quite some time I've been using custom nginx error pages on this site.
error_page 429 @custom_error_429;
location @custom_error_429 {
internal;
more_set_headers 'Content-Type: text/html';
echo '<html>...</html>';
}
Now while implementing custom error pages for a different project, I tried to see if there is an easier way to do this. Instead of generating and defining a specific error page for each error, a single error page is used for all errors.
error_page 400 401 402 403 404 405 406 407 408 409 410 411 412 413 414
415 416 417 418 421 422 423 424 425 426 428 429 431 451 500
501 502 503 504 505 506 507 508 510 511 /error.html;
location = /error.html {
ssi on;
internal;
root /var/www/default;
}
nginx provides the status code as variable to our error page, but we also need the error message to make it more userfriendly.
map $status $status_text {
400 'Bad Request';
401 'Unauthorized';
402 'Payment Required';
403 'Forbidden';
404 'Not Found';
405 'Method Not Allowed';
406 'Not Acceptable';
407 'Proxy Authentication Required';
408 'Request Timeout';
409 'Conflict';
410 'Gone';
411 'Length Required';
412 'Precondition Failed';
413 'Payload Too Large';
414 'URI Too Long';
415 'Unsupported Media Type';
416 'Range Not Satisfiable';
417 'Expectation Failed';
418 'I\'m a teapot';
421 'Misdirected Request';
422 'Unprocessable Entity';
423 'Locked';
424 'Failed Dependency';
425 'Too Early';
426 'Upgrade Required';
428 'Precondition Required';
429 'Too Many Requests';
431 'Request Header Fields Too Large';
451 'Unavailable For Legal Reasons';
500 'Internal Server Error';
501 'Not Implemented';
502 'Bad Gateway';
503 'Service Unavailable';
504 'Gateway Timeout';
505 'HTTP Version Not Supported';
506 'Variant Also Negotiates';
507 'Insufficient Storage';
508 'Loop Detected';
510 'Not Extended';
511 'Network Authentication Required';
default 'Something went wrong';
}
Now we have the status and the status_text variables available in our error.html page. <html><body> <h1><!--# echo var="status" default="" --> <!--# echo var="status_text" default="Something went wrong" --></h1> </body></html> | ||

| .: Happy 20th Birthday x-log On June 2nd 2002 I published the first (test) entry in this weblog. The first entry has disappeared since (thus making the second entry the first one in the archive of June 2002).
Compared to 20 years ago, the about page no longer needs to explain what a weblog is. Also the weblog here has changed quite a bit. Initially its content was more on the pure web-logging side (commenting on interesting links I encountered during my daily Internet surfing) mixed with some kind of a journal/commentary of my day-to-day life. Later on it moved more towards a 'knowledge dump' on technical topics mixed with some music discoveries and random personal post from festivals and travels. And lately it has been rather sparse again with posts, still mostly on technical topics around coding, networking, security mixed with some personal posts commenting on the current world situation. From the list of linked Blogs in 2002, only deep-resonance aka mk is still active, special shout-out to Markus for the continuous persistence. | ||

| .: Non à la guerre! Nein zum Krieg! Today I went to Bern to the rally for peace. Swiss media reported that this was the largest rally for peace in Switzerland since the rallies against the war in Iraq in 2003. That I can link to my own blog entry regarding the rally for peace from 19 years ago, makes me sad. Besides showing up to the rally, I also did donate to the ICRC to provide humanitarian aid and I do encourage you to do the same. | ||
