Protocol buffers are a flexible, efficient, automated mechanism for serializing structured data think XML, but smaller, faster, and simpler. You define how you want your data to be structured once, then you can use special generated source code to easily write and read your structured data to and from a variety of data streams and using a variety of languages. You can even update your data structure without breaking deployed programs that are compiled against the "old" format.

Protocol buffers are now Google's lingua franca for data at time of writing, there are 48,162 different message types defined in the Google code tree across 12,183 .proto files. They're used both in RPC systems and for persistent storage of data in a variety of storage systems.

Value Added Tax (IVA) increase from 15% to 16%

There was a great improvement regarding the original proposal by our de-facto ruler (why de-facto? Because it is still unclear whether he won the popular vote. He has about the same legitimacy as George Bush during his first term: Legal but illegitimate): In Mexico, there is a category of items regarded as fundamental, which are exempt of IVA (tasa cero). This category includes food and medicines Of course, this category makes up the bulk of the poorer people's consumptions, so they pay much less IVA than people with higher living standards. For a very long time, there has been a push to remove this exemption. This has been fortunately clearly understood and fought against. So, the presidential initiative, as I was saying, contemplated a global 2% tax which would not be IVA, and which would be applied universally. This tax would be earmarked to be applied to social programs, and was euphemistically called Impuesto de Combate a la Pobreza (poverty combat tax). Many people applied the concept of duck typing (if it looks like a duck, walks like a duck and quacks like a duck... It is a Value Added Tax). As many analysts, I believe this tax was meant to be the foot in the doorstop, leading to point out in a couple of years that anyway nothing is IVA-exempt anymore and the world has not come to an end, and we should apply universal IVA... So, the reduction in the increase (2% 1%) is not the most notable thing here The notable (and good!) thing is that they didn't succeed into killing the tasa cero.

3% tax on telecommunications

Many friends have started rallying (with the IMHO least effective way of protest you can find on Earth, just by stating their adherence in their Twitter and Facebook profiles. Wow, great deal!) that the original proposal included a 4% tax on telecommunications, and it appears that 3% will be applied. They say, quite fairly, that telephone and Internet access are no longer considerable a luxury, but a need to power the society into becoming better prepared, more competitive. My friends state as a contrast the Finnish ruling broadband access as a citizen right. What they seem not to realize is that the proportion of taxes in Mexico (collected from the responsible taxpayers, which is not by far the way for the bulk of the money in this country) is close to 30%, taking into account the big taxes (IVA, ISR/IETU) and the host of smaller ones. In Finland, the percentage of taxes payed by every person and remember that tax evasion is way lower than here!) is over 50%.

So What is my opinion on this? What would my ideal tax scheme be?

• Nobody likes taxes. But the country needs far more infrastructure, far wider inverstments. We need higher taxes But we need those taxes to be collected from people with higher income. And yes, that would mean I would most probably pay more (as I do sit relatively high on the income scale Qualified work, even if you do not seek money for the sake of it, pays much better than non-qualified work; remember the minimal wage in Mexico is around MX$50 a day - Less than US$4 or 3).
• The increases should be applied to the income tax (ISR). It is supposed to be around 30% for income levels over MX$5000 a month, with a very slight increase after that point. Income tax is highly deductible now, and most people with high income manage to ellude most of it. Many cases have been documented of companies as small as Walmart paying less than MX$1000 a year due to several (intentional? you bet!) holes in the legislation. That is where the bulk of the extra government income should come from!
• For a couple of years, since I registered as a taxpayer (people receiving money exclusively as salaries under a given limit don't have to declare taxes) I have decided not to hire an accountant to make the numbers look prettier, and just do the numbers myself over the platform provided by SAT/Hacienda (the tax collecting authority). Yes, that means I am paying more than what I could But it also means I am paying what I should! And it is an expensive point of view, but I strongly invite others to do the same. If we criticize Walmart for making numbers look prettier, shouldn't each of us do the same? Shouldn't we all care to pay what we are supposed to, so that the government has enough funds to carry out its tasks?

Yes, I am painfully aware that an important portion of what gets into the government disappears due to corruption and ineptitude. Still, the only position from where I can criticize is from being clearly legal. The same point as I do with software: I cannot ask people to comply with my Free Software licensing if I use ilegally propietary software, can I? So no, I don't use any. Even legal propietary software, free-as-in-beer (i.e. Flash player). So, please think this over before you join the Lemmings into complaining about the tax increase. Yes, this is a bad moment to increase taxes. Yes, Mexico is the worst faring country in all of America in its response to the crisis; the GDP will probably fall between 8% and 10% this year and 2010 will not be much better. Yes, it would be better to increase competitivity. But, yes, we pay ridiculously low amounts of taxes And those of us who can afford a little reduction in our expenditure should do it. And those who make gross money should just stop it. Oh, and last point, regarding the #internetnecesario Twitter hashtag: Don't be Lemmings. Internet should be recognized a basic need for a free society. But right now in our country, it completely is a luxury, even if you cannot live without it. If you are Internet-addicted as myself, you most probably will not notice the 3% increase. FFS, We will pay MX$360 instead of MX$350 a month for my Infinitum connection. Will we really notice? In Mexico, middle and upper class are Internet-enabled. Lower classes are not. Things should change, no doubt. But it is not at all comparable to an universal IVA. Things should change and universal connectivity should be a given. But right now, calling Internet a basic good... is just out of touch with reality.

• performance and RAM usage improvements: most significant is a tremendous speed-up of the function that calculates dpkg calls sequence, achieved by throwing away standard Graph library and writing a small private one, optimized for Cupt usage


• support of '-y' command-line switch


• reinstalling packages is now possible

Ubuntu has taken a voluntary-sector aim-for-100%-free distribution, built a private-sector free-and-non-free distribution and gets more love and free marketing from free software supporters than its parent, or than the whole-community events.

The silver lining is that most Ubuntu improvements are free software and are/can be contributed back to the free software world.

• Be considerate
• Be respectful [...] It's important to remember that a community where people feel uncomfortable or threatened is not a productive one.
• The important goal is not to avoid disagreements or differing views but to resolve them constructively. You should turn to the community and to the community process to seek advice and to resolve disagreements.
• When you are unsure, ask for help. Nobody knows everything, and nobody is expected to be perfect in the Ubuntu community

A person purchasing a product is focused on the features and benefits and the salesperson is focused on closing the deal. If the topic of installation does come up, a user thinks, Who cares! My sysadmin will install it for me! as if such services are free. Ironically, it is the same non-technical executive who dismisses installation and upkeep as if they are free who might complain that IT costs are too high and go on a quest to kill IT spending. But I digress. I can understand why a product might be difficult to install. It is hard enough to write software, and with the shortage of software developers it seems perfectly reasonable that the installation script becomes an afterthought, possibly given to a low-ranking developer. The person purchasing the product usually requires certain features, and ease of installation is not a consideration during the procurement process. However, my ability to install a product affects my willingness to purchase more of the product.

• When I edit a file, the temporary swap file gets committed, and then deleted as the changes get committed
• If I make a whole lot of changes the script can fire multiple times, or even fire before some changes fully happened
• Maybe I want a shadow folder maintained and committed, rather than just this folder
• Perhaps it would be a good idea to push the repository elsewhere
