Application development vs Kernels and drivers development

When speaking about how to develop software, one is usually making the difference between drivers, OS and rest of the application software.
It is always about different strategy in developing the software. The lower software layer have to be generic, scalable and easy to use, if possible. The developer is applying some paradigm, even defined by the OS itself and has to optimize the usage of the hardware. The primary customer of his application is the colleague next to him who will develop further the application


The application has slightly different constraints. It has to meet the expectations of the customer, as well as to implement non-functional requirements. Now, the customer is identified and the generic cases are not in the focus. One can argue that re-use of software is a trend now. A trend yes, but a primary focus very seldom.

Then, it is the pressure of delivery date. The generic development has some buffers in the timescale. The application has to meet the delivery date to customer. This is not easy to negotiate and it is part of the product to be delivered. The generic software is part of a strategy. We start early, it is nothing yet defined and there is no recipe how to do it.

This fight with uncertainty combined with the scarcity of information in what regards the new technology is giving the developers of basic software this aura of pioneers or medieval knights who are pushing the limits. The others, as harsh it might seem, are actually the bourgeois who are the core of society and they are keeping where there are the existing limits.

mai este programarea o meserie elitista?

ai facut calculatoare... poti sa imi re-instalezi windowsul?
fa-mi si mie o configuratie buna ;)

Asa arata cultura ""populara" cand am terminat facultatea. Cum o fi acum? S-a schimbat oare perceptia?
Mai sunt absolventii de facultati tehnice favorizati ca statut? Cred ca inca sunt, prin prisma angajatorilor care curteaza studentii valorosi din anii mici.
Pe de alta parte, in urma cu 10-15 ani, programatorii erau un club restrans, care avea cunostinte bune de programare. Acum, pe urma democratizarii programarii prin "drag and drop", programare fara pointeri, PHP for dummies etc. programatorii sunt mai putin retrasi intr-un turn de fildes.

Voi ce parere aveti?

Manager? Leader? Both?

Seth Godin has an interesting point here

The difference between management and leadership is widely discussed and certainly there are major topics where the difference is clear.

If you are a boss, think about how much you see yourself as a manager and how much as a leader. Then, try to capture feedback to understand if the others seem you in the same way. Put the feedback back into your own system and adjust yourself as described in theory of self regulated system. Look for your own equation.

Democracy in software engineering?

Article first published as Software is Democratic on Technorati.

Maybe you have read "Funky Business". Two Swedish professors, Jonas Ridderstrale and Kjell Nordström. are writing about how information open more opportunities for less developed countries.
Internet access is cheap, the need for application is great and the offer is high. The quality can vary, but this happens in all the cases, no matter the origin of the author. Now, the most significant competitive advantage is the intelligence of the software engineer.
The engineering is democratizing in what regards software. With a decent speaking of English, a decent internet connection and anyone can challenge the old markets. MIT is publishing courses on their website Many other universities do the same. Internet is full of tutorials and courses. So the information is easy to grasp and use at will
One can argue that you need licenses for the tools. This is partly true. On one hand, there are plenty of frameworks for free. You need a few bucks to be able to publish apps on Apple Store. Or the well known platforms of download, where you can offer your products.
As well, the pressure from emerging markets can be seen in highly specialized markets. Telecom, automotive electronics are now produced all over the world. The development locations are spread in the same way. A few months ago, Bosch opened a new development center in Vietnam. How do you find this? I find it as a natural step to globalization.
The funny thing is that salaries in developed countries are not going down, even with this equality of chances. This is, IMHO, due to large increase in demand of applications. Suddenly, you can sell thousands of applications on web stores. Nevertheless, compared to 10 years ago, I do have at least 5 devices which embed software. The new TV set I would like to buy has even WiFi included. My fridge has a complicated algorithm of freezing. The oven can be set in all kind of programs. I don't have an iPhone. Still, my phone has internet connection, camera and calendar included. I expect that average gadgets do have more lines of code than AppleII computer.

So, there is room for everyone. The next thing will be to transfer all this programming mindset from single processors to multiprocessors. Let's see how this will change the world.

Unit test

Do programmers test? If yes, do they think that testing is somehow dishonoring them?
Do great programmers have a great testing technique? YES.

I noticed that most of the programmers hate to test their work before integration in a bigger product.

I will come back to testing, attitude and tools.
