Der er desværre nogle kriminelle, der har opdaget min kortlink-service lnk.dk og bruger siden til at lave korte links, der peger på forskellige phishing-formularer. De fleste på fransk, enkelte på dansk.
Jeg vil helst kun have, at min side bruges til lovlige formål, og derfor har jeg i første omgang lavet et kontrolspørgsmål i formularen til at oprette links. Jeg håber, at det kun er ærlige mennesker, der kan svare på spørgsmålet, og at det er relativt nemt for dem:
Nyt kontrolspørgsmål om en kendt dansk cykelrytter på lnk.dk
For at implementere det nye felt, redigerede jeg min Django-applikations forms.py med feltet og krav til validering:
from django.forms import ModelForm
from django import forms
from .models import Link
from django.core.exceptions import ValidationError
class LinkForm(ModelForm):
everyoneknows = forms.CharField(label='Hvad er fornavnet på cykelrytteren, der vandt Tour de France for mænd i 2022?', error_messages={'required': 'Indtast cykelrytterens fornavn'})
def clean_everyoneknows(self):
answer = self.cleaned_data['everyoneknows'].lower()
if answer != 'jonas':
raise ValidationError("Det fornavn, du har indtastet, er forkert.")
return answer
def __init__(self, *args, **kwargs):
super(LinkForm, self).__init__(*args, **kwargs)
self.fields['destination'].widget.attrs['placeholder'] = 'https://eksempel.dk/meget/lang/url'
self.fields['shortlink'].widget.attrs['placeholder'] = 'eksempel'
self.fields['shortlink'].label_suffix = "" # Remove colon after label
self.fields['shortlink'].required = False # Not required in form
def clean_shortlink(self):
shortlink = self.cleaned_data['shortlink']
return shortlink.lower()
class Meta:
model = Link
fields = ['destination', 'shortlink']
labels = {
'shortlink': ('Evt. selvvalgt kort link:'),
}
error_messages = {
'destination': {
'max_length': ('Din destinationsurl er for lang til denne kortlinkservice.'),
'invalid': ('Din destinationsurl er ikke en gyldig adresse. Husk http://, https:// eller ftp:// foran dit link, hvis du har glemt det.'),
},
'shortlink': {
'unique': ('Det selvvalgte link, du har valgt, er allerede i brug. Find på et andet.'),
'max_length': ('Dit selvvalgte link må maksimalt være 100 tegn langt.'),
'invalid': ('Du kan kun bruge bogstaver (dog ikke æ, ø, å - kun ASCII-tegnsættet), tal, bindestreg og understreg i din selvvalgte adresse.'),
}
}
Det bliver spændende at se, om ændringen har nogen effekt.
Today I received an e-mail telling me about something to do with making money through ads. I used to have an AdSense account for making sweet money on the internet, but I closed it years ago, partly for earning hardly anything, partly for being tired of tracking my few website users for cents.
I tried the Sign in link in the e-mail to see if I could possibly get rid of future mailings about a product I am not using. This took me down a rabbit hole of errors and user-unfriendly help pages…
An unwanted mail from Google
When I clicked Sign in I got to a page saying my account was closed (this I knew), and would I like to reactivate my account?
It looked not unlike this image, which I found somewhere. Now I wish I took a screenshot, but for reasons I will disclose later, I am not able to access the page anymore:
Google telling me my account is closed, but still sending me e-mails about it
Does YouTube hold a solution?
Seeing as the original e-mail mentioned YouTube, I thought I might have a setting somewhere on YouTube I could disable to un-link my YouTube videos from my closed AdSense Account.
After 5 minutes of browsing I concluded that no such option existed.
In which I try to get support
Next I thought if I could just delete my AdSense account instead of merely having it closed, I might just get rid of further mailings.
I looked for a delete option somewhere, but none existed, so I tried Google AdSense Help. I tried more eloquent expressions than “delete adsense account”, but all options only led to something called Community. And DuckDuckGo’ing “delete adsense account” led to many Community requests for deleting accounts, but only answers such as You can’t ‘delete’ an Adsense account. You have to close it properly, following the official instructions. (I really like the quotations around delete in that quote.)
Community does not equal a contact option, Google.
Try the opposite!
Next I had a stupid idea. How about reactivating my account, look for an option to disable mailings and closing it again? Counter-intuitive, I know, but I have succeeded previously with similar tactics.
This happened when I clicked the reactivation link on the account closed page. The error is fully reproducible by clicking the link again, which I tried:
I finally got ENGINEERS on the case, but not in the way I hoped
I’ve got rights
As a citizen of Europe, I have certain rights. One of those is contacting big corporations holding data about me and telling them to delete my data and having them refuse due to something they call legitimate interests which roughly translates to making dollars by knowing my shopping interests.
I went back to AdSense support and slowly typed Fully delete my account under GDPR to let Google know I mean business.
I was happy to see an actual envelope icon in a button saying e-mail. I clicked. This happened:
I finally thought Google took me seriously, and maybe they do, just not seriously enough for a working e-mail contact
Det irriterer mig hele tiden at blive spurgt, om jeg har lyst til at blive overvåget med cookies på diverse hjemmesider. Det har jeg ikke.
Det undrede mig, at jeg, fx ved besøg på PriceRunner, synes jeg blev spurgt om det samme igen og igen i deres cookie-dialog:
PriceRunners hyppigt forstyrrende cookie-dialog.
Forskellige udløbsdatoer på “ja” og “nej”
Jeg undersøgte udløbsdatoerne på PriceRunners cookies, og det viste sig at:
Siger du “Nej tak” til cookies, udløber den cookie, der registrerer, at du ikke vil overvåges efter 2 timer. Når der er gået 2 timer, og du besøger PriceRunner igen, bliver du spurgt igen.
Siger du “Ja tak” til cookies, udløber den cookie, der registrerer at du gerne vil overvåges efter 1 år. Du kan altså besøge PriceRunner igen og igen (meget relevant her i Black Week) uden at blive forstyrret med nye cookie-spørgsmål.
Ja til cookies på Pricerunner. Du får lov til at genoverveje dit samtykke om 1 år.Nej til cookies på Pricerunner. Du får lov til at genoverveje dit nej om 2 timer.
Må det være sværere at sige nej end ja?
I slutningen af oktober 2021 forsøgte jeg at få afklaret, om praksissen er/var lovlig.
De flinke folk i Datatilsynet har udarbejdet en vejledning om cookiedialogbokse. Hovedlinjen i vejledningen er, at det ikke skal være sværere at være “anti-cookie” end “pro-cookie”. Her er et par citater:
“Et samtykke skal være frivilligt. Formålet med betingelsen om frivillighed er at skabe gennemsigtighed for den registrerede og give den registrerede et valg og kontrol over sine personoplysninger. Et samtykke anses derfor ikke for at være afgivet frivilligt, hvis den registrerede ikke har et reelt eller frit valg.” (side 12)
“Elektroniske samtykkeanmodninger skal ikke være unødigt forstyrrende, men det kan samtidigt være nødvendigt, at samtykkeanmodningen til en vis grad forstyrrer brugeroplevelsen, hvis anmodningen skal være effektiv. Opgaven for den dataansvarlige er således at vælge en løsning, der rammer den rigtige balance.” (side 16)
“Derudover skal det generelt som nævnt ovenfor også være tilsvarende let at afstå fra at give samtykke til behandling af sine personoplysninger, som det er at give det.” (side 17)
Jeg synes det lød som om, at der var en chance for, at PriceRunners (med mange fleres) praksis var ulovlig.
Det var den (umiddelbart) ikke.
Ingen hjælp at hente hos Datatilsynet
Desværre synes Datatilsynet ikke, jeg har en sag. I mine øjne er det svært at få øje på andre begrundelser for hele tiden at spørge om samtykke ved nej til cookies, end at tilskynde til, at brugeren på et tidspunkt takker ja, samtidig med at risikoen for at klikke ja ved et uheld stiger, jo oftere man bliver spurgt.
Men: Det beskytter databeskyttelsesreglerne ikke mod i Datatilsynets vurdering. Her er kernen i argumentationen:
“[…]databeskyttelsesreglerne beskytter retten til at give samtykke, herunder at betingelserne til et gyldigt samtykke er opfyldt. Det er i den forbindelse Datatilsynets vurdering, at uanset at hjemmesidens cookies har forskellige udløbstidspunkter baseret på, om du giver samtykke, eller afviser at give samtykke, ændrer dette ikke på, at du som bruger stadig har mulighed for at afvise hjemmesidens behandling af oplysninger om dig. Der gives således fortsat brugeren et frivilligt valg.
Datatilsynet vurderer endvidere, at det faktum, at du som bruger oplever flere gange at skulle afvise hjemmesidens behandling af personoplysninger ved brug af cookies, ikke er et element, som databeskyttelsesreglerne beskytter den registrerede imod.”
I like to document my doings and for about 15 years I’ve been documenting the books I have read. First in Notepad, then in Excel and finally in Python and Django with a database somewhere in the background. I am amazed what experts help amateurs achieve.
This post explains the proces of collecting data about my reads in little detail and in too great detail the code behind the page.
Some books of 2020Statistics
Finding information ONLINE
Most data was crawled from Danish library ressources, Goodreads and Wikpedia with varying success. A lot was entered manually, especially with works in translation. I spent hours and hours being pedantic.
Even though librarians have been managing data longer than anyone else on the planet, there is no autoritative relational database where you can look up when some book by some author was first published and when the first Danish language version came out. In defence of librarians, many writers go to great lengths to make data management on books hard (one example is the genre “non-fiction novel” used by Spanish writer Javier Cercas).
The mysteries of Goodreads
I was mystified by the ability of Goodreads to place study guides and commentary to great works of literature first in their search results (and many more strange things) and terrified by Google displaying available nowhere else I could find on the web author birthdays on top of search results .
Also, Goodreads magically has editions of books that are older than when Goodreads claims the book was first published.
Goodreads: When what you’re searching for is nowhere near the first hit
How does this autocomplete work?
I wonder?
First published on April 5, but first listed edition is from March 23. Huh?
Adding books
After crawling for data, I made a form to add new books:
Step 1. Push “Look up”PROFIT!
The form
This was a breeze in Django. Here’s forms.py:
from django.forms import ModelForm
from books.models import Author, Title, Read
class AuthorForm(ModelForm):
class Meta:
model = Author
fields = ['first_name', 'last_name','gender','country','biography','birth_date','data_quality']
class TitleForm(ModelForm):
class Meta:
model = Title
fields = ['title','genre','read_language','original_language','publisher','isbn','published_date','first_published','cover_url','ereolen_url','biblo_dk_url','good_reads_url','pages','original_title']
class ReadForm(ModelForm):
class Meta:
model = Read
fields = ['date']
The view:
And here’s the logic from views.py (I probably shouldn’t uncritically be saving cover URLs found on the internet to my server, but):

The views.py function for the front page is short and sweet:
def index(request):
context = {}
context['request'] = request
reads = Read.objects.order_by('-date__year', 'date__month','sort_order','id').select_related('title')
context['reads'] = reads

return render(request, 'books/index.html', context)
And, while longer, I think the template loop is nice too, (although there is that clumsy nested loop):
{% regroup reads by date.year as years_list %}
{% for year, readings in years_list %}
<h2>{{ year }}</h2>
{% if year == 2015 %}

<p>I was working in England from around September 2003 to February 2004. This gave me time to read a lot, but not the computer access at home necessary to register my reads precisely.</p>

Efter at have hentet en masse flotte fotografier fra internettet, havde jeg brug for lidt grovsortering. Jeg ville fjerne de fotos, der havde for lav opløsning til, at jeg gad kigge på dem og måske på et senere tidspunkt printe dem ud.
Jeg bruger først “walk”-funktionaliteten fra biblioteket os, som lader mig lave en løkke-funktion gennem alle mapper, undermapper og filer fra et sted på min harddisk.
Derefter bruger jeg Pillow til at hente størrelsen på hver led af hvert foto og udregner arealet. Hvis et foto er lig med eller større end 3 megapixels (3 millioner pixels) beholder jeg det. Er det mindre, sletter jeg det.
Her kan du se, hvordan jeg gjorde:
# megapixels.py
# Author: Morten Helmstedt. E-mail: helmstedt@gmail.com
'''A program to go through a directory and subdirectories and delete
image files below a certain megapixel size.'''
import os # Used to create directories at local destination
from PIL import Image
import PIL
save_location = "C:/Downloads/"
contents = os.walk(save_location)
for root, directories, files in contents:
for file in files:
location = os.path.join(root,file)
if not ".py" in file:
try:
image = Image.open(location)
area = image.size[0]*image.size[1]
if area >= 3000000:
print("stort", location)
image.close()
else:
print("for lille", location)
image.close()
os.remove(location)
except PIL.UnidentifiedImageError:
if ".jpg" in file or ".png" in file or ".jpeg" in file or ".tif" in file:
print("deleting:", location)
os.remove(location)
except PIL.Image.DecompressionBombError:
pass
Hvis du har været på internettet, er du sikkert en gang stødt på sådan ét her:
Mange webadministratorer vælger at skjule disse oversigter over filer på en webserver, som webserversoftwaren Apache kan generere automatisk.
Men jeg opdagede ved et tilfælde, at jeg kunne se, hvad fotoagenturet Magnum havde lagt op i deres WordPress-installation.
Jeg besluttede at forsøge at lave en lokal kopi, så jeg kunne kigge på flotte fotografier uden at skulle vente på downloads fra internettet.
Først forsøgte jeg med Wget, som er et lille program, der er designet til at dublere websteder lokalt. Men Wget havde problemer med at hente og tygge sig igennem de lange lister med filer. En af dem fyldte fx 36 megabytes. Det er altså rigtig mange links.
Derfor lavede jeg et lille Python-program, der kan tygge sig igennem denne type mappe- og filoversigter og downloade dem lokalt.
Her er det:
# apache-directory-downloader.py
# Author: Morten Helmstedt. E-mail: helmstedt@gmail.com
'''A program to fetch files from standard apache directory listings on the internet.
See https://duckduckgo.com/?t=ffab&q=apache%2Bdirectory%2Blisting&ia=images&iax=images
for examples of what this is.'''

På kukua.dk kan virksomheder i kulturbranchen komme i kontakt med studerende på Institut for Kunst- og Kulturvidenskab på Københavns Universitet. Tænk: Opslagstavle.
Det er gratis for de fattige, (men kreative), virksomheder, som fx får dygtige praktikanter uden at betale en krone for det.
De virksomheder, der har kompetencerne til det, registrerer sig og lægger selv deres opslag op.
Kapitel 2: Jeg får en mail
Den 15. april 2019 modtager jeg dette fra en studentermedhjælp hos virksomheden Copyright Agent:
Kære Kukua.dk Vi er blevet opmærksomme på, at I sandsynligvis har krænket ophavsretten, da vi ikke kan finde belæg for anvendelsen i vores systemer.
Som billedbureau ejer Ritzau Scanpix videresalgsretten til det pågældende billede som er markeret med en rød firkant i det vedhæftede dokument, der yderligere indeholder dokumentation for den krænkelse, vi mener har fundet sted.
På den baggrund er Ritzau Scanpix overfor ophavsmænd, forpligtet til at søge vederlag og godtgørelse, for billeder som er publiceret uberettiget. Selv om det måske ikke har været jeres intention, så er det en krænkelse af fotografens ophavsret at publicere det uden gyldig licens eller tilladelse.
I det vedhæftede materiale er generel information, dokumentation, faktura og opgørelse af kompensation til rettighedshaver samt “Ofte stillede spørgsmål – og svar”.
Da Ritzau Scanpix oplever et stigende antal ophavsretsbrud på deres materiale ser de sig nødsaget til at finde og police deres materiale, så de også i fremtiden kan levere kvalitets materiale til deres kunder.
Copyright Agent samarbejder med en række professionelle fotografer og førende billedbureaueromkring sikring af deres ophavsret på internettet. I kan læse mere om Copyright Agent her: www.copyrightagent.dk
Hvis I har spørgsmål eller dokumentation til sagen, så er I meget velkomne til at besvare denne e-mail eller kontakte os telefonisk på 70 273 272 mandag – fredag fra 9:00 – 17:00.
Oplys venligst dit sagsnummer, hvis du kontakter os telefonisk, så vi har mulighed for at hjælpe dig i den konkrete sag.
Med mailen er vedhæftet en pdf-fil, der fortæller, at jeg har brudt ophavsretslovgivningen, med en faktura på 3.437,50 kr., som jeg skal betale “inden 10 dage fra dags dato“.
Her kan du se pdf-filen – blot har jeg bortcensureret det billede, Copyright Agent har sat ind for at dokumentere min påståede krænkelse af ophavsretten:
Så jeg tænker straks: Det har som sådan ikke noget med mig at gøre. Ligesom politiken.dk ikke er ansvarlig, hvis jeg kommenterer på en artikel med hele teksten fra Syv år for PET, (blot de fjerner den igen når de bliver opmærksom på ophavsretsbruddet), er jeg ikke ansvarlig, når jeg i god tro går ud fra, at mine brugere selvfølgelig har lov til at publicere de fotos, de publicerer – det er jo trods alt deres egen kreative branche, der lever af ophavsretten.
Så jeg svarer fluks:
Kære Fatima
Det er en bruger på siden, der har lagt det pågældende billede op. Alle kan selv registrere sig på siden og lægge indlæg op.
Så vidt jeg kan se, er den pågældende selv ansat på – eller har tilknytning til – Posthus Teatret. I indlægget står hendes telefonnummer, så jeg synes I skal ringe til hende og spørge. Jeg fjerner hjertens gerne indlægget og/eller fotoet fra siden, såfremt jeg modtager en tro og love-erklæring fra jer på, at I ejer ophavsretten på fotoet.
Mvh Morten
Fatima svarer:
Kære Morten Jeg vedhæfter dokumentation for, at Ritzau Scanpix har ophavsretten til billedmaterialet. Vi vil kontakte Posthus Teatret. Tak for hjælpen.
Jeg sletter billedet fra kukua.dk og skriver:
Kære Fatima
Jeg har slettet billedet fra serveren.
Og Fatima svarer:
Kære Morten
Det er noteret, at billedet er fjernet, hvilket vi takker for.
Og jeg tror at alt er godt. Men det er det ikke…
Kapitel 4: Rykkeren
Den 14. maj 2019 modtager jeg en ny mail fra Fatima:
Da betalingsfristen er overskredet, sender vi en lille påmindelse. Ved manglende tilbagemelding i løbet ad ugen, vil vi sende rykkere i sagerne med de oprindelige beløb.
Vi har ordnet sagen – og derfor regner jeg bestemt med, at du frafalder kravet.
Og jeg tror at alt er godt. Men det er det ikke…
Kapitel 5: Inkassovarsel
Den 12. juni modtager jeg denne mail fra – gæt selv – Fatima:
R2, krænkelse af ophavsretten – inkassovarsel
Kære Kukua.dk
Vi har tidligere fremsendt krav om kompensation for krænkelse af vores klients ophavsret. Vi har fortsat ikke registreret jeres betaling og fremsender hermed vedhæftede rykker i sagen.
Copyright Agent samarbejder med en række profesionelle fotografer og førende billedbureauer omkring sikring af deres ophavsret på internettet.
I kan læse mere om copyright Agent her: www.copyrightagent.dk
Hvis I har spørgsmål eller dokumentation til sagen, så er I meget velkomne til at besvare denne e-mail eller kontakte os telefonisk.
Vær sød at ringe til mig ved lejlighed på 25 80 16 54. Vi har allerede afsluttet sagen, men du bliver ved med at kontakte mig.
I øvrigt har jeg også besvaret alle dine tidligere e-mails.
Og for nu at sige det helt klart: Jeg har ikke tænkt mig at betale for en mulig krænkelse af ophavsretten, som det ikke er mig der har begået.
Kære Fatima
Vedhæftet er dokumentation for, hvem der – hvis der er foretaget en krænkelse af ophavsretten – har foretaget den, ved at uploade det pågældende billede til den server, hvor kukua.dk ligger. Du kan rette eventuelle krav til den person.
Jeg beklager den tilsendte rykker, hvilket blev sendt ved en fejl. Vi tager sagen videre med Posthus Teatret.
Jeg håber at det er endt godt for Posthus Teatret. Jeg ved stadig ikke, om de havde lov at benytte billedet af deres biograf, men at Copyright Agent går efter en fattig kulturinstitution for (efter eget udsagn) at hjælpe fattige kreative, viser tydeligt at Copyright Agent kun gør deres fejlbehæftede, inkompetente arbejde for pengenes skyld.
Kapitel 6: Hvorfor dele historien?
Så hvorfor offentliggøre min runde i managen med Copyright Agent?
Så andre, som i den lignende historie med advokatfirmaet Njord, der uberettiget sendte fakturaer på downloadede film til hvem som helst, kan læse om Copyright Agents forretningsmodel og -metoder til skræk, advarsel og måske hjælp, hvis de skulle være så uheldige at modtage en mail fra virksomheden.

Ej, jeg havde allerede prøvet at simulere Krig, men synes det kunne være spændende at få logikkerne til at hænge sammen med interaktivitet (dog højst begrænset) og logikker for rent faktisk at vise spillet.
Nu har jeg gjort et forsøg og jeg har kommenteret en masse i koden, så den forhåbentlig er nem at følge med i.

Due to the order of player b's shown cards being different than for player a, this loop to show cards
in case of war is a little different from player a's.
The slices variable contains pairs of values saved as strings that the Django template filter |slice can
understand, e.g. "1:5". These are looped through so that only parts of b_cards_on_table corresponding to
the slice is looped through for each single, double, etc. war. The loop through b_cards_on_table is reversed
because the card being turned is shown left of the hidden cards in the war.
