In Excel you can easily fill in a column with a list of values. Some times also in Emacs you my need to write down a bunch of similar code. The dotimes function with the “elsp eval” M-x : (Esc + : on windooze) will solve your trouble easily. Try out this code on scratch buffer:

A new version of an Arduino Realtime OS is on the go:

I have used with profit and fun NilRTOS, and I strongly suggest to you this new variant.

A preemptive multi tasking RTOS in a 2KB 1-MIPS, 8 bit microcontroller remember be the ugly time when a MS-Windows 3.x with 1 MB of RAM was an inferior operative system no-preemptive at all, but with nice software like Excel and Access

AngularJS is indeed a good framework, but if you lose some grip on it (i.e. you go in vacation for 2 weeks), it is very complex to re-grasp.

Also I have seen junior JavaScript developer confused my $scope use.

JavaScript on client side has damned destiny: it is too easy to develop a framework from scratch: so roll you dice, cross your finger and find plenty of AngularJS alternatives

Today I took a light rail with my son, to bring him to school. That tram is 90 years old. It has been maintained for 90 years. Milan city sold some of them to San Francisco too.

Oracle SQL Developer is full of nice feature, damned by a overwhelming options pane, like the one I will describe to you right now.

Even if  Oracle databases (<12) does not support auto increment, you can easily ask to your sql data modeler to generate for you a sequence and a trigger in a automatic way.

Sometimes in University I found bold young guy saying something like:

I will reimplement this in machine language because is faster

I will reimplement this xyz C function by my own

My program crash, I think there is a bug in HP UNIX socket implementation

I will ge rid of this Java Garbage Collector because it is too slow. I will reimplement all the code in my C++ routine.

Belive me: your code is doomed. A full list of guys have already done your same code, found a million bugs and corrected it in the tool you want to replace because they are shitty slow, to your eyes.

I feel your pain because I made your same mistake. Keep reading.

Oracle SQL Developer is full of nice feature, damned by a overwhelming options pane, like the one I will describe to you right now.

I will show here a very fast way of comparing different database and auto-generate migration script.

1. Reverse engineer the source database using Oracle Data Modeler
2. Now select the right arrow  shown below:
3. Select the destination datasource (more here) when asked.
4. The compare pane will enable you to compare the databases. But the default options will also use schema name to detect different object, so you will not get what you want in every scenario. In 50% of my daily job, schema are different, so you must select the options below to fix it: Select "Options" and then "Compare options". Then  de-select "Use schema property" like suggested below:
5. Push the "Sync new object". Then push the "DLL Preview" button and inspect the generated database.
6. Bonus: by default the tool will not include tables to drop. Inspect the two pane ad check the table you want to drop in the left pane.
7. Refrain launching the script without proper testing. You are migrating your valuable data.

Pandoc is an universal document converter to convert Markdown, Org-Mode, Html, Word documents from one markup format into another  After using different tools, (including GNU info and SGML). I find out pandoc vert handy.

The BBC Micro bit an ARM-based embedded system designed by the BBC for use in computer education in the UK. The device has been given away free [...] [to every 11 years old pupil] in the UK, and is also available for purchase by anyone.

This is the wikipedia definition.

To increase performance and SD life of your raspberry PI 2/3, you can follow my first article on this subject.

You can easily increase even more the SD life if you can trade a bit of RAM.

The key idea is to take advantage of tmpfs, which can be resized on the fly too.
