2019-01-12 Enabling some old web userdirs 5 months ago
I received a "complaint" that a very old site on the webserver wasn't working anymore. I am not a person to just stop something without planning that so this was an oversight. It was one of the userdirs on idefix.net: Ivo van der Wijk who hasn't updated the page sinds 1994. No, really, not even the broken links. In restoring this one and the others I found that php in userdirs is disabled by default nowadays, found via PHP not working in userdir (public_html) - devPlant. Maybe a good idea, but I only enable php on virtualhosts where I want it, so I disabled that rule. I hadn't missed it on my own webspace yet, but a site like Het online dagboek van hester (Renate) in Australie (en daar in de buurt) depend on PHP completely. While I was looking for the reason the php failed I also noticed that /etc/apache2/mods-available/userdir.conf also has some configuration I do not appreciate, it enables userdirs globally when the module is loaded:<IfModule mod_userdir.c> UserDir public_html UserDir disabled root <Directory /home/*/public_html> AllowOverride FileInfo AuthConfig Limit Indexes Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec Require method GET POST OPTIONS </Directory> </IfModule>I disabled that part: I only want the userdir to work on specific virtual hosts.
2018-10-21 One of my first radio contacts (re)confirmed 8 months ago
From time to time I check whether eQSL has new incoming confirmations for PD4KH contacts. Recently I found one for a contact that goes way back, and it was before I used a linux radio logging program so I did not have the details stored in my logging program. But my website still has those details: Vanavond vanuit de achtertuin contact met PI4HAL via repeater PI3UTR. It turns out PI4HAL decided to stop sending out paper cards and started using eQSL. I guess they uploaded all old logs. I do remember the contact and being nervous about actually talking "on the air" and finding my turn between other callers to that station. This was a trigger for me to check my old logs and make sure I upload things correctly to ARRL Logbook of The World including the few satellite contacts. Oh and I never started using hrdlog as PE4KH. It did not add a lot for me.Read the rest of One of my first radio contacts (re)confirmed
2018-09-24 After 25 years with sendmail there was still something to improve 9 months ago
I still like running sendmail on my own systems. But sendmail evolves with time and my configuration does improve slightly sometimes, such as on the introduction of authenticated smtp with secondary passwords. After the recent upgrades to the home server there is a new mail server with some other new details and suddenly other systems at home could not relay. A bit of searching found Best practice: sendmail and SMTP auth with the right flags for the DAEMON_OPTIONS to only offer authentication on port 587 (submission). I noticed the local systems tried relaying via port 587 so I changed this to port 25 where IP-based relaying is allowed. No idea why I set this up to use the port 587 when I set it up previously. And yes, I checked it, I started with sendmail in 1993, so 25 years of sendmail on port 25. I did start with writing my own sendmail.cf rules but I switched to .mc based configurations.
2018-09-14 IT attacks in higher education have interesting holiday patterns 9 months ago
According to this article: Students blamed for university and college cyber-attacks - BBC News the new pattern is that attacks on IT systems in higher education happen in active times in education. Interesting quote (for me):There was a very sharp decline in attacks in the Christmas, Easter and summer breaks and during half-terms - with attacks rising again sharply when terms resumed.I remember starting in system administration and learning quickly that the Christmas holidays period was the busiest period in attempts to break in to computer systems all over the world. This was simply explained by the fact that the Christmas holidays are the most universal school holiday in the world and all the teenage hackers had time to play with computers, modems and networks.
2018-07-10 Found the original article about Steven K. Roberts and his recumbent bicycle Behemoth 11 months ago
I noticed the Nomadic Research Labs site was cleaned up a bit more, so I searched again for the article that I read in August 1995 about Steven K. Roberts and his recumbent bicycle Behemoth: "Big Electronic Human-Energised Machine ... Only Too Heavy". The scans are at BEHEMOTH in Kijk – Dutch Magazine. Interesting detail is that the top left text refers to a picture of a Challenge recumbent. I recently ordered a new Challenge recumbent! Maybe I should find out whether I can find that page of that magazine. Several things can be related to seeing this article: buying the book Computing Across America, selecting a recumbent bicycle later in life and this idea in the back of my head of future recumbent cycling trips.
2018-04-06 25 years of Linux use 1 year ago
In looking at a problem with the linuxcounter script I noticed I am now passing the 25 years with Linux mark. I first saw it in the beginning of 1993 when part of my internship happened at the 'expa' lab (if I recall correctly) of Hogeschool Utrecht with SLS Linux. Anyway, still using Linux a lot. It's been an interesting 25 years!
2018-02-01 TV plannen van 50 jaar geleden 1 year ago
Iedere maand verschijnt er een Electron van 50 jaar geleden op Electron 50 jaar geleden en daar kijk ik graag even in, om het 'nieuws' op amateurradio gebied van 50 jaar geleden te zien. In die van Februari 1958 viel me een stukje op onder het kopje "Televisie" met:Voor onze lezers is het wellicht interresant, te weten dat Philips op Maandag het normale TV-programma relayeert in band V: beelddraaggolf 772,25 MHz, geluidsdraaggolf 777,75 MHz. Amateurexperimenten in deze band zijn van veel belang, want ondanks de ontvangstmoeilijkheden, die er nog zijn, kon het toch wel eens dé TV-band van de toekomst blijken te zijn. Een voordeel van deze band is natuurlijk in de eerste plaats het grote aantal beschikbare kanalen - de band loopt van 610-960 MHz! -. De commerciële televisie, die in ons land ook nog eens op gang hoopt te komen, vlast natuurlijk op een aantal kanalen in die band. Een ander voordeel is, dat de antennes zo klein kunnen zijn, hetgeen het stedenschoon ten goede zal komen.Ondertussen is analoge TV opgekomen in de UHF band en weer gestaakt. Opvallend is voor mij ook dat de genoemde draaggolf frequenties niet uitgekomen zijn op latere UHF kanalen. De afstand van 5 MHz tussen de audio en video draaggolf klopt wel met de analoge TV op UHF standaarden van later. Commerciële TV via de analoge etherkanalen is er nooit gekomen, dat is heel lang tegen gehouden en later via kabel/satelliet opgekomen en pas bij de digitalisering kwam er ruimte voor digitale TV via de ether. Het deel van de UHF band gereserveerd voor TV-kanalen is ook gekrompen, ondertussen zijn we aan het werken naar een einde bij 700 MHz. Mooi om zo'n voorspelling te zien en te vergelijken met de huidige realiteit.
2017-11-13 The television version of "The Cuckoo's Egg" 1 year ago
I read the Dutch version of "The Cuckoo's Egg" when it came out in 1989. Later I bought the English version. Via a complete diversion I found out this weekend the book was made into a TV documentary: The KGB, the Computer and Me which has a lot less personal diversions than the book. It is played by Clifford Stoll himself and others involved in the original story. Although the CIA guys look a bit more stereotypical than they come out in the book. A very interesting part is there is a closing remark in the documentary by Markus Hess. Now I want to get a view of the movie of the other side, '23'. The funny part is that I found this documentary from following news related to amateur radio: Cliff Stoll -- K7TA -- Has THE KNACK. And a GREAT NOVA Video. Clifford Stoll does have a callsign: K7TA
2017-10-15 Getting to play VIC-20 games again 1 year ago
Ages ago my first homecomputer was a Commodore VIC-20. I did basic programming on it and played some games. I remember the game Centipede and loading games from audio cassette. These days games seem to be enormously complex and expensive or filled with advertisments. I don't like these, the last time I seriously invested time in a game was Pinball Dreams. I found out about the VIC-20 emulator xvic, part of the vice package. I even bought a cheap USB joystick to use. I never had a joystick with my VIC-20 so it was about time to get one. This joystick is a DragonRise Inc. Generic USB Joystick (yes, including the spaces) and I noticed today it wasn't working right: up and down on the joystick did not work. I found out eventually the left and right on the second stick mapped to up and down, thanks to a simple joystick tester from Joystick - Denialwiki in 7 lines of Basic. Some searching found DragonRise USB Driver Issue - RetroPie which mentions this issue in hid-dr.ko happened in Linux 4.4 - 4.9. I did not feel like going back to compiling my own kernels for this laptop, but there is a simple solution in Ubuntu 16.04: use hwe (hardware enablement) kernels. These seem to be aimed at the long term support server versions, but they fix my joystick problem and I can play centipede.
2017-09-01 The right to be forgotten versus keeping history 1 year ago
For ages the whole 'right to be forgotten' issue was something happening to other people for me. The worst I do on my website is name spammers that keep sending me unsollicited e-mail. This changed when I started playing with old files from BBS Koos z'n Doos including old BBS lists. A few years after I started putting these on-line I received a request to remove a name from the lists. This person advertised running a 'hardcore sex' BBS in the 1990s. But in 2013 the rather unique name of this person showed up with a decent company and in this BBS list. I could imagine that this person had no idea in the 1990s what someone might do years later with that information. At the same time it felt bad to 'change history'. Those were original files, it felt bad to change them. But after consideration I changed the name to spaces. I also received notice from the google webmaster program that some search results are hidden on bbs.idefix.net. I have no idea which ones or what names I should mask. The whole 'right to be forgotten' is a typical 'shades of gray' subject.

2016-05-27 Reminded of Computing Across America 3 years ago
A fellow radio amateur posted an old picture somewhere of Steven K. Roberts on the Behemoth "Big Electronic Human Energized Machine, Only Too Heavy" bicycle, a recumbent bicycle with computers and amateur radio as a joke suggestion to me. But this is more than just a joke to me, I follow the work by Steven K. Roberts since somewhere in the 1980s when I saw an article and picture about him in a popular science magazine. Articles and pictures by Steven K. Roberts are now collected on microship.com where some of the old memories seem to have gone the way of the 404 after almost 30 years of gathered digital history have been reorganized. Steven is still busy with the same ideas, nowadays on a nice sailboat, as can be seen at Blog - Technomadic & Gonzo Engineering with regular projects. Browsing the site I found some interesting videos such as the ones in Vintage Video: Computing Across America - Hackaday and Computing Across America - April 1988 - Louisville WHAS11 Bernson's Corner - Youtube.com.
2016-03-26 Adam Curry discovers new geek hobby, tries it immediately 3 years ago
I have been following Adam Curry on and off since the Curry & van Inkel show on the radio in the Netherlands years ago. He is a hobby pilot and active in amateur radio. Recently he heard about skywriting with gps/aprs and went all in: Digital Sky-Writing by Adam Curry and I found it on Skywriting with APRS - /r/amateurradio on reddit. Comments on reddit aren't too favourable, it is clearly a first try but I am amused by Adam's actions. Have fun, Adam.

This is really old-school: I see messages in the newsmaster mail from a newgroup/rmgroup war. Haven't seen that in email@example.com asks for christian.binaries.sermons to be created. If this is acceptable, type: /usr/lib/news/bin/ctlinnd newgroup christian.binaries.sermons y firstname.lastname@example.org And do not forget to update the corresponding description in your /var/lib/news/newsgroups file. The control message follows: .. For your newsgroups file: christian.binaries.sermons Christian sermons CHARTER: christian.binaries.sermons is a newsgroup for Christian sermons. The newsgroup and hierarchy will not be strictly moderated per se. Spam and heavy trolling is not permitted, however, and may be post-moderated after the fact. The christian top-level hierarchy does not follow the precise policies of the current free.* hierarchy. We do, however, share a similar vision of a relatively free and open hierarchy allowing almost anything created by virtually anyone, with few rules. JUSTIFICATION: Christianity being one of the world's largest religions, there are several Christian newsgroups in various hierarchies out there, but no established central structure that combines a variety of topics, and especially Christian binaries are fragmented in disjointed hierarchies throughout the Usenet. This newsgroup under the free.* mantle espouses the ideas of freedom, the liberty to create your own group, and allow relatively free posting with the exception of spam and heavy trolling. As Christian newsgroups are often trolled, this is a necessary evil for the hierarchy to thrive. In this new age of persecution and ostracization, the christian hierarchy is necessary to unite Christians worldwide and give them a digital home. There has been much discussion on the Usenet regarding the need for separate Christian groups, especially topic -specified binaries groups, which seem to be largely absent in terms of Christian media. The amount of Christian material found in any typical web search on this subject alone is sufficient justification for this group.I'm not sure usenet binaries are the best way to reach christians today. The church I visit uses live-streaming with availability on a mobile 'app' and the archive is available via the church website.

Ik kwam wat papieren tegen van het BBS Koos z'n Doos en de vlakke scanner is weer beschikbaar, dus ik heb die papieren weer eens gescand. De rekening van de harddisk uit Februari 1993 en de kerstkaart uit December 1993 zijn nu echt goed gescand en beschikbaar in hoge resolutie. Wat ik ook nog tegenkwam was een rekening voor een ROM upgrade van het SupraFax 14k4 modem uit December 1993. Opvallend, de aanschaf van het SupraFax 28k8 modem was Juli 1994. Ik weet op dit moment niet precies wat de reden was van de ROM upgrade, ik ga er van uit dat het te maken had met het definitief worden van de v32.bis standaard. De SupraFAXModem 14400 pagina op Wikipedia Engels geeft hierover geen informatie.

Vandaag is het precies 34 jaar geleden dat 27 MHz communicatie in Nederland werd geintroduceerd, 27 MC artikel op de nederlandse wikipedia. Ik luister wel eens met een scanner naar 27 MHz verkeer, erg vermakelijk.

Searching for the print header - COM port cable in the PC parts junk box for the new weatherstation on the alix.1c board gave 5 of them, 2 with db9 connectors and 3 with db25 connectors. I tested them all with a real telephone modem. In total 3 worked, 2 didn't but that may be because there are two different standards for it.

Nu ik bezig ben met ritchie als weerstation computer en tegelijkertijd even keek in mijn Linux Counter entry naar wat 'oude' systemen. Wat ooit een topsysteem was (500 MHz pentium III met 512 Mb geheugen) is nu oud ijzer en ongeveer dezelfde specificaties (500 MHz AMD Geode met 256 Mb geheugen) is een minimaal systeem met verminderd energiegebruik. Grappig hoe de zaken veranderen.

An interesting bit of cold war history: when the British army had a large number of people stationed in Germany a TV station was set up, BFBS Television which still runs in areas where the British army is active. Back in the 1980s satellite home distribution wasn't an option so first videotapes where sent from the London studios to the German transmission center(s) where they were transmitted to the families using low-power local UHF tv transmitters. 'Current affairs' programs such as the news were only delayed by about a week, less urgent programming could be delayed by up to 6 weeks. In 1983 a microwave link England - France - Belgium - The Netherlands - Germany made live transmissions possible from London, a major and costly upgrade. The first live transmissions were the ITN and BBC evening news programs both of which mentioned their new audience.
