Several times I have wondered, does IBM really have a team of testers in connection with Lotus Notes development?
..or are things just tested á la "this seems to work OK, ..next" ?
I have come to the conclusion the later is sometimes the case.
If you have used the new "slide in a summary" pop-up feature in Lotus Notes 8.5.3, which shows a window when new mails have arrived, you may know what I mean
By analyzing the behavior of the pop-up it seems to pop-up when a new mail has arrived to the database, however the content of the pop-up is another story .
The content seems if based on a combination of a random selection of unread documents from the inbox, mostly new ones and are often the same mails repeated.
The junior developer, who coded this ...send a few mails to himself, saw a pop-up window, smiled and said "this seems to be working all right.. "
NO, it does not work all right !
Testing is not about simulating a simple "normal" scenario only, It is about getting out in abnormal weird scenarios too.
Hints to IBM:Mail rules may actually move a document to a folder, so it is actually never shown in the Inbox? OK?
It is not uncommon to use mail rules, the pop-up window was clearly NOT tested with a combination of mail rules.
Only show me the "new" mails in the pop-up list ONCE!, my users are freaking out and are really annoyed, ..ONCE !
Was this feature tested on real users?
Clearly not, users like subtle, discrete hints of a new mail has arrived ....ONCE!
The principles are actually rather simple:
Compare date/time when the pop-up was last run with creation date for documents from a date/time sorted list of all documents (not only inbox) in the mail database
Show only incoming mails and unread
The classic recycle design pattern is flawed in some document iterations
Fri, Apr 26th 2013 7:57a Jesper Kiaer As we all know you need to recycle your Domino Objects in Java to free up the back-end C++ objects, or your server will crash in the end.
People in general use the same pattern when iterating through documents.
Something like this:
Document doc = view.getFirstDocument();
while (doc != null) {
Document tmpdoc = view.getNextDocument(doc);
doc.recycle();
doc = tmpdoc;
}
This will work in must situations, but in at least one situation you will get a serious NotesException:

Using Solid-State Drives in your servers? Beware research show risk of massive data loss
Tue, Mar 12th 2013 4:46p Jesper Kiaer If you like me are using Solid-State Drives (SSD) in servers because of the great performance ...beware!
New research show that 13 out of 15 Solid-State drives will suffer data loss or worse when they lose power.
That is really scary numbers! ... so maybe it is time to check the UPS again? ;-)

Why your Notes directory suddenly grows several Gigabytes
Mon, Sep 24th 2012 3:08p Jesper Kiaer Today I was cleaning up they hardrive containing my Lotus Notes installation. It is installed on a Solid State Disk and it had only 5 Gigs left. It is known fact that a SSD must have plenty of free space otherwise it is going to crash and burn way too soon.
I was looking to clean up my Notes installation a bit, but first I needed take a backup of it and I noticed it was very large. During the backup, which was actually a simple copy, I saw it took a long time to copy several files, hence they h [read] Keywords: lotus

When the order is crucial - use of both compression and encryption on data.
Mon, May 7th 2012 6:46a Jesper Kiaer Sometimes the order in which things are done is really crucial.
An example to this is the mix of encrypted and compressed data.
Should you:
Compress encrypted data ?
or
Encrypt compressed data?
Due to the nature of encryption and compression the answer is of course very obvious, but I will anyhow back it with a small example.
I have created some simple Java code which does the following:
1. Takes an XML file with domain names and creates an DES encrypted file from it.
2. Creates a compress [read] Keywords: java

Flaw in popular mobile apps exposes users to identity theft - storing passwords in plain text files
Mon, Apr 9th 2012 1:47p Jesper Kiaer Storing passwords in plain text files on an iPhone??
You would think it would be very obvious that this a very bad idea, right?.
But NO! ..Facebook, LinkedIn, Dropbox (again?) and others thinks this is a great idea...well at least until Security researcher Gareth Wright revealed how they handles security in their iPhone Apps (and most likely Android too he says).
Again this makes you think...when such a fundamental security rule is broken, which other are broken too?
Outsourcing anyone?

The old joke of making somebody read complex names out loud in an airport, which actually means something very different, (still funny)
Tue, Mar 27th 2012 1:43p Jesper Kiaer Found this joke in an very old mail...
This is an absolute classic.
you must read the story first. Its a bit complicated the story, but basically
they wait for a flight from a far away place and then write down names to
give to the announcer at the airport and then go near a speaker and record
what they say
This is his story.....
"We'd go and sit on the balcony at Terminal 3 at Heathrow,
directly under one of the speakers as the roof is low. We put the tape

Importing Holidays into the Lotus Notes Calendar
Thu, Mar 15th 2012 5:34a Jesper Kiaer There are a few simple steps to update a Lotus Notes Calendar with holidays for your country or religion.
The administrator:
Open up the administrator client and go to the "Configuration" tab.
Go down to the "Miscellaneous" section and open up "Holidays".
You will see entries for each country or religion. They may look old but they are actually repeats so they could be quite valid.
My old entries here are good for 10 years.
The newest Holiday entries are kept in the NAB template.

Thu, Feb 23rd 2012 2:49p Jesper Kiaer If you really want to stress test your hardware and software solutions nothing does it better than a free porn site.
Youporn.com runs Redis as their primary database, which of course is a NoSQL database.
A cluster of Redis databases handles over 300.000 queries per second!!. and over 100 million page views per day.
That is a hole lot of queries and page views...
