Sometimes you want to automate some SSH command execution and don't really care about checking the remote machines in ~/.ssh/known_hosts. Warning: do this only if you really understand the consequences! I.e. it is very silly to ignore known_hosts on any machines across the Internet. It makes some sense on intranet, where servers are rebuilt frequently and where external access is restricted. And even then think long and hard before using this trick:
You might have heard, that Trolltech has recently released a new version of their famous QT library with preliminary support for Android and iPhone (iOS) support. This is, actually, pretty exiting news, because it means that, at least in theory, one can have a single mobile application code base for two most popular smart phone platforms on today's markets. And, possibly, for most desktop computers as well, because QT runs pretty well on Windows, Linux and Mac. Throw in support for QNX / BlackBerry 10, which QT also provides, and the prospects become almost irresistible.
For the last couple of years I repeatedly see submissions of spam comments to my web site, which advertise "essay writing services" (read - cheating at course assignments for money) for students. I receive at least a couple a day, sometimes tens of them. This is despite having enabled CAPTCHA validation of comments submissions. The spammers' software manages to circumvent this protection, albeit not always - most of the undesirable content is stopped. What really puzzles me, however, is the extremely poor wording of these spam messages.
Released some time ago new C++11 standard introduced lambda functions - long anticipated and exciting feature. On the other hand, boost::variant has been around for awhile and is used successfully in many projects. The recommended and type-safe way of applying type-specific logic to values of variant types is using visitor pattern. However, a visitor is a functor, which until now should have been defined separately, in a class of its own. It would be nice if we could use lambda functions to achieve the same functionality.
Python allows you to send calendar appointments (invitations / events) directly from your code. It is quite easy to create a new appointment in the standard iCalendar format (ics). You can do it by hand or use a convenient icalendar open source module. In order to convince Outlook, however, to present the iCalendar events as native calendar appointments, you will need to make some effort. Fortunately, other people have already collected all the necessary pieces.
Google provides APIs to access its data using various languages. You can manipulate Google calendars, contacts, documents etc. Most of the time the usage is pretty straightforward, but sometimes it is not clear how to achieve a specific goal. For example, it took me some time to figure out how to download all events for a given calendar. The main reason behind the difficulty is the upper limit Google places on the number of calendar entries returned by a single query. There are API calls, which help you to overcome this constraint. Below is the relevant code for your enjoyment.
Sometimes you might need to generate tables in good old plain text. Python can be used to perform this task. Here's a link to the relevant python recipe. Alternatively, there is a ready made module TextTable, which is also quite convenient.
Google Contacts allow setting birthdays, which are then picked up by Google Calendar automatically and displayed as events on the relevant day. This is very convenient for keeping track of your relatives', friends' and other people's birthdays. Having a reminder saves you an embarrassment of forgetting your girlfriend's/boyfriend's/auntie's day of birth and prevents unnecessary bad feelings.
