PedrojETA crisis managed

Posted on by david

Sorry this is a Google Translation, please refer to the version in Catalan to read it better

The crisis generated as a result of a post denouncing the manipulation fotoperiodística the newspaper El Mundo has been maintained in a Kafkaesque but clever (worthy of study) by its visible face, Pedro J Ramirez. For those who do not know if the link above says it all. Reactions to the blog turned into tag # pedrojETA Trending Topic. So we have all the ingredients to be considered that there was a PR crisis that the company had to manage. Given this situation, follow five basic steps:

Find out the origin
Getting the chip honesty
Report
Demonstrate concern
Maintain two-way communication

And that’s what made the director of the newspaper. And if we’re talking about a book since, despite regular follow recipes, this time chose to take the 4th point and rotate it like a sock, which is the most spectacular part of the affair. How is that? Perhaps some examples follow.

Inditex and exploited labor

A few weeks ago I broke the face of news that the PR of Inditex of its products was manufactured by exploited workers. The company showed concern and was quick to correct that problem, you did not know (mmm, respected point 2?). Suppose you had said “this has always been the case and because of this that people can earn a living honestly and we can wear clothes at low prices.” That would turn into an exercise in point 4 of strong commitment and unpredictable consequences.

We can continue with other examples in this blog

The two sides of the coin of the crisis

Españolito that Vienna
the world has Guardea God.
one of the two Españas
the heart must helarte

Antonio Machado

The peculiarity of this crisis is that consumers felt outraged. On the contrary, the medium has the full complicity of the consumer in the matter. And talking of the two Spains and the medium is doctrinaire leader of one of them, so that the other is the Spain of which the tweets. And as long as they fight, they do talk about different things.

The position of the critical

There are partial aspects of reality that severed the joint deform the meaning of events.

Joan Brossa

Critics spoke of journalistic ethics. The newspaper claimed that deceives its readers, who brainwashed every day without being aware of it. To take a picture and cut it into pleasure is like taking a sentence and cut it to pleasure (something in which the newspaper already has experience). That this is a pwned as a farmhouse and the newspaper would have to drop our heads in shame for being so uninformed and your readers can not continue to rely on what it says.

The position of the medium

Next the invention will Statesmen cheap lies, putting the blame upon the nation That is attacked, and every man will be glad conscience-soothing falsities of thoose, and will diligently study them, and refused to examine in refutations of them, and I will Thusis by and by convince Himself That the war is just, and will thank God for the better sleep after I enjoy this process of Grotesque Self-Deception

Mark Twain

The half-speaking mission. And his mission is to inform, but to lead the ongoing war between the two Spains, with a selection of information, holders, covers, throwing slogans, scoring strategies and unifying standards of thought and action. Therefore, this case of violation of journalistic ethics is, in the words of the director’s own rating: “The Pulitzer.” In other words, says a contributor to The World in this post. What at first seems a daring escape forward, it was a strategy that we expect (that I can say now, at last ball in first half I was surprised). We are talking about a leader without discussion, without having to shrug in the face of any crisis and that the only thing that can happen with this is get more strengthened. He claimed to have won more than 1,000 supporters in the few days it lasted.

For him, the image was clear and clear slogan:

“We believe that the banning of the left abertzable by way of charges of terrorism and condemn the politicians who are not skilled enough to outlaw them and the judges were so unfair as to leave them participate in democracy. “Even in a photo showing three letters.

Sure, the Pulitzer

The first Apple

The timing of the withdrawal of Steve Jobs, one of the brightest business minds of the change of millennium, it is better to revise the beginning of the story: the Apple I, launched in 1976.

It is the materialization of an idea not too immunity, as many as had been similar to that time: a computer with the power of a scientific calculator with an operating system itself (ehem, better say firmware ), where one could record a cassette tape texts, receiving teleprinter (who came to the phone line) and learn to program in BASIC and assembler. It also could play. While connected to a TV that does not form part of the product. The keyboard would not be ergonomic. Why it was necessary to sacrifice the design? It was impossible to spend many hours working on it on a device like this.

The innovation was that it represented the great usability to work with a keyboard reminiscent of a typewriter at a time when computers operated switches with lever.

They were marketed and implemented. Cost U.S. $ 666.66. It was handmade, Jobs made the room, and when was small, the garage at home. They sold 200 units in just over a year when they released the Apple II.

Served but not much got what they wanted: to be the ones who did it and everyone is n’assabentés. They opened a window to the microcomputer and it would attract attention, some of which later facilitate the financing to make things bigger. Surely the 200 buyers moved more by passion than by the problems awaiting solutions. It’s worth having a computer on 24 hours to save the sound of a teletype when it arrives? How teletype devices were finally pushed aside with the purchase of an Apple I? I do not think too much.

The realization of this watermark was the work of one mind: Steve Wozniak, a co-worker of Jobs who designed the kit complete. But as he did? What was your point?

Building a computer

In March 1975, Woz, a designer of calculators 24 years at Hewlett-Packard, had long dreamed to have a microcomputer and attended a meeting with a bunch of nerds like him. And they talk about technology. He learned what a microprocessor and this was the fact that he lacked. On leaving the exciting conversation began to think about design. That night came the whole idea of ​​what would be his own personal computer.

It gave workers the chance that HP could acquire the MOS 6200 microprocessor for only $ 20 (!). In his job working with a video terminal (screen) which took out the chips. This used to connect the terminal to the ARPANET. Or put another way, the Internet then.

The firmware was for the two PROM chips. This is a chip with a suitable machine can be programmed as a CD. Working at HP, I had everything I needed. Even an oscilloscope that he might need to see what was wrong connections.

With the RAM it had gone well. But his friend Steve Jobs, who also worked there, got him branded Intel reports that the much improved design. Not only that, but today’s memory design that still holds. It seems that this friend was getting very good things from people. In addition he was very passionate with the computer and asked him if one day they might or might connect to a floppy.

The computer should have a language. And so Bill Gates had been known to write a program in BASIC interpreter. And he brought him to the code (!). So he decided that his work computer with BASIC.

With all this, his friend Steve Jobs convinced him to form a company. He did not say anything to win money. He led the drive. Steve Jobs, to harness the talent of Steve Wozniak aroused his passion. He said that if left would have had at least a good company.

And with the Apple I and this sentence, the story begins.

Apple I

Right to forget

Posted on by david

Sorry this is a Google Translation, please refer to the version in Catalan to read it better

A story about a new lawsuit against Google I was surprised by the number of confusions that accumulates. After over 30 years an explosion of a liquefied gas tanker truck exploded in front of the campsite Alfaques, killing over 200 people (foreign to the area), is the memory of what happened but always, not much will revive. Now the news comes to be:

A court of Amposta has agreed to hear the complaint of the company against Google Alfaques Holidays Spain, to cause them losses, the results start showing both URLs as images, content related to the massacre. The applicant claims the right to oblivion and believes that Google’s algorithm is in part because Hipercor Casino and the MGM in Las Vegas have more satisfactory results [more ...]

I think the story (do not know how true is the fact), there is some confusion

Right to forget

Most would say that the invocation of the right to oblivion has to be a confusion of journalists (we have already killed two messengers, and the Google). I do not think people in the world right down to it. The law is the oblivion concerning the privacy of a person who made a moon-shining to a nightclub when he was 18 years and two decades later, the penalty paid is entitled to not be associated with a given name. But even an accident that led to changes in legislation, urgent investment in infrastructure and has been studied in risk management and emergencies during these decades, a case can be difficult to forget.

Who is Google

A company in California. We must be there to report it. Spain is a Google advertising manager. It is very difficult to draw on anything from the contents of a court building.

Google Algorithm

Imagine this fictional story:

The court agreed to hear the poppy is the reporting of a company against a financial consultant for including external audit, pursuant to the General Accounting Plan, the cost to generate a stock that has come to find out.

Unimaginable. But similar. Maybe someone will say you can not compare with the General Accounting Plan of Google’s algorithm. Certainly he is right. The Google algorithm is an authority stronger than any law of any financial state.

Before you give this news, the company that would perhaps be to hire an advertising company to sell these stocks. With Google’s results just happens. MGM Las Vegas and Hipercor have to spend much money due to its image during the years following the tragedies. I have generated a lot of buzz of its own needs. This has led to many images (and some beautiful) and many results on content generated by them have done down the unwanted results. That is, they care brand.

What to do in these cases

What to do in these cases is simple. Hiring an SEO specialist, who works as http://www.argus.net these results. With beautiful photos, interesting for the client with new content. After a time, undesirable results would begin to decline to be lost in the crowd.

Putting two and two together

Posted on by david

I’ve just finished reading the book “Espanya, Capital París” authored by Germà Bel and soon available in english, published by Sussex Academic Press (by now, only in its original, spanish, and the in language of the author, catalan).

A few points touched me particularly and this is what I’d like to share with the blog readers. I’ll raise some issues that refer to the content of the book, but not giving the answers as they are within the book, what is gonna be unpolited until it is published in english. Sorry for that, but this post is just about my personal view.

This is not a letter from a catalan persuading spaniards for a larger self-government in Catalonia. It is a work made in spanish for spaniards (as it looks to me) to show them off another Spain should be possible. It is a book written by an economist with a wide historical view. An advantage reflected in the structure of the book, that made it easy to understand for non economists.

After reading it, I have a more practical, less romantical view of what a nation-state is, with a failure-story that might be ported to other spanish stories.

Productivity

What is a nation-state? It is a tool built by humans, in order to become more productive

Now I can better understand and explain why a tailor from Seville will always be less productive than a less skilfull one from Hamburg.

Solidarity

So many politiciens have shut themselves down before this issue, in Madrid, it becomes good to understand what a fallacy it is and how pathetically they all have knelt before the bureaucratic project of a centralist conception of the building of the spanish nation.

Mistakes fixing

Century after century same mistake has been observed and deepened into it. Even when someone or all the bureaucrats have decided to fix it, they have deepened, even more, in the mistake. Spanish bureaucrats have their role and they will never give it over.

IT infrastructures

After reading a book about the spanish failure in transports, as a computer engineer, I’d like to read its analogy about IT infrastructures and I’d join a crowd funding pursuing this target.

Open WiFi

Posted on by david

This post was written using google translator. Refer to original post in catalan if you wish

Often there is open wifi and we have not considered how far it is safe to accept the invitation. Nice to know how can someone who has opened their wifi, or what can we do. A WiFi (Wireless Fidelity) can be opened in one of the 3 following cases:

Someone who is not aware of his generosity and open wifi is unknowingly or simplify (when a friend is not necessary to pass the password). Sometimes we think it is true that the neighbors do not connect to the internet.
Someone who wants to have an open wifi at home. For when friends come. Because he likes it when someone passes on their iPhone, take advantage of 10 minutes to send the whatsapp.
Someone who loves: collecting passwords!

In all three cases it is necessary to put a scanner with which we can see who is using our wireless and if abused.

What you need to monitor activity and distigir friends and smartphones step neighbors parasites? Usually the router will not give us enough. To be informed of what we want, the most complete Linux is a smell that all information given to us and as we ask. So all that is needed for it to happen:

The internet, the router gives the supplier. We can use wifi to use your private password on the system that offers strong encryption the router.
A computer that fits with a Linux disk space to store the data and two network cards.
A WiFi Access Point (bridge), if necessary, with a good pair of antennas, if you want to be very “generous.” This can be merged with the former, ie, we can put a card in Linux, that provides wireless access. In fact this is the best option.

Once we have this, since we only need to put the Linux network configuration, connect the Access Point, open it to the general public and configure Linux. When we say that Linux is an Ethernet to connect the router to connect other al’Access Point.

Thus, we have a powerful tool manages all the traffic we provide. Great. We can monitor at any level.

WiFi for friends who visit us

Because we want to have a wifi open for friends who come home and also for some people not only want to see consumption. This will give us the tool Iptraf.

apt-get install Iptraf
Iptraf

It’s that simple. If we work in the-B background. All data shall be / var/log/iptraf/ip_traffic- *. log file and this will tell us what use is being made of our bandwidth.

It will be full of lines like:

Sat Jul 30 17:13:30 2011; TCP; wlan0; 52 bytes, from 192.168.1.38:45882 to 212.121.243.175:80; being FIN, 8 packets, 5212 bytes, avg flow rate 6.83 kbits / s
Using grep and awk, we can have very accurate information of what is being done with the connection.

If the Access Point we have internal tools that can be used to monitor gate-level MAC address (identifier of the device, which he gives to the Access Point). This can give a more accurate as it could be giving different IPs on the same host, which will complicate the analysis. However, the MAC can be changed at will from the device, which can make us dance a little head.

Until this level, the market offers as Access Points that provide information, but the aim of this paper is to obtain a 359 ° view of what can be done with an open WiFi.

Spying abuses

The abusers must know that they are very easy spied upon. In fact can not expect much courtesy from the moment they have no problem making us waste resources without permission.

There are tools like tcpdump. This video shows us, for example, how to get the password of FTP. It’s simple, shows that it is easier to do than to explain it:

Restricting access

The iptables tool allowing them to take care that we cut open the wifi and access to a particular IP (to see if he realizes).

iptables-I INPUT-s 192.168.1.111-j DROP

This means that IP does not have internet access. We can do anything to cut access to a site specific to a particular service (stream, mail, web), restrict to only one service (allowing mail make check), a website (open gmail, etc.). We have total control, while not changing the IP, which is not at all difficult, because our parasite can change the MAC. So maybe the end will cease to offer open WiFi to friends and people passing through.

Pictures properly stored

Posted on by david

The digital photography involves a problem with an unclear solution: storage.

We should be satisfied with our storage system if its security is comparable to the value we give to our collection. Therefore, photographs of family, which is seen as children grow, etc., the system must be very secure and save them addientment must decide what combination of resources selected.

Photographs printed

The traditional way has a high reliability. Not suffer from viruses or hard faults. The human error can destroy the very least but with digital storage. And they are not likely to form part of the spoils in case of theft. Still wear out over time and can not be reused as digital. Is the most expensive. Reserved for the best pictures.

Hard Drives

The most convenient and cheaper. But the most susceptible to any of the contingencies: human error, soft and hard, theft and accident. A good option is to have hard drives that are different in different places, so one of them suffers a contingency, recover data immediately. The problem is how to keep up to date copies (it is a well-designed infrastructure and ongoing work).

CDs / DVDs

One way to expensive and unreliable, but comfortable. CDs and DVDs with expiry date and only they know. So we also have parallel devices, and check periodically that exist, so if the “worms” have eaten inside a DVD, which was recovered from his back.

The cloud

A system cheap, comfortable and, to some extent reliable. However, existing systems do not guarantee total. We also have to look far if you can get to know exactly how to find a company keeps our files. Ideally, one that stores them in duplicate, on different datacenters located in different countries. And that keeps deleted files for 48 hours, to compensate us for a human error. Finally be demanding, should be energy efficient to the point of not providing the service for immediate download, but we need to ask to have them and when we say we will, so that hard disks are turned off while in do not need. You do not have our pictures made up the price of oil.

The closest I’ve found that’s Picasa Web Album. Do not tell us how to save the file or provide guarantees. The human error does not prevent, but we can apply their own systems, as have images in a separate account, not memorize the password in the browser and view it from another guest account. Please note that depending on how we get there the images can be applied destructive compression, so the photos do not keep 100% of their properties. It cost a dollar for every 4 Gigabytes annually, which can be expanded in blocks as we need.

There are other sites like Amazon S3, dropbox, Ubuntu One, etc., each with different offers. They treat images as files, so we suffer for compression. There are many services, we must remember that any of them may disappear one day, without warning (would not be the first), so we must measure our confidence.

A couple of tools to help us save space and organize it

fdupes

At the moment we decide that a particular system, that maybe we would not have the images organized and that we should get together. For this purpose it’s great to have a tool like fdupes, reporting and / or cleaning of a duplicate directory. First look at the md5sum of all files to compare the contents of that match and also compare the content, ignoring the long filenames.

Fdupes .–r -1.

Report duplicates of all existing

Fdupes .–r-d-N.

Clear all duplicates, deleting from the second case, as has been the previous execution.

EXTRACT

It gives us all the metadata of a photo, interesting if we are out of control the order of pictures and want to sort dates.

-p extract date IMG_8808.JPG

tell us the date of photography. This tool, combined with grep and awk, you can create scripts that we classify thousands of photos in seconds.

Therefore: Combination of devices on an organization’s optimal

Depending on the level of security we can use different combinations.

Confidence in the cloud: keep all files in the cloud service. Or perhaps better, in two different. We periodically review both are correct.

Upper level: keep all files in the cloud service and a home device (external HDD or DVD). We reviewed periodically.

And, as always, we are never quiet, which is what happens to humans when we have things we value

Tècnica Pomodoro

Posted on by david

Sorry, this post is a translation from catalan version using google translator.

The technique is a recipe Pomodoro with the intention of increasing productivity. It consists of control making us the breaks follow the guidelines of time, so we have no excuse to daydream (now called procrastinated) outside the established periods.

Program consists of a clock-shaped tomatoes (hence the name) so that every x minutes (we think) starts a break for a few minutes. There are few breaks short breaks after long day.

I’ve tried. I installed a tool called RSIBreak advised that it is time to rest. Even if you do not if I put the screen all black. I can say that I postpone the rest.

Well, my experience (and I speak from a very spontaneous use of the tool) is that my virtual tomato is always wise to tell me just to rest when I’m more inspired. So do not respect that never breaks proposed. Moreover, there are times that I ever do a proper break: When you download a file, start an application cost, etc..

Once the radio I heard an interview saying that he is scheduled breaks. The other people did find geeks like grid too. I just tried it now, I’m an ill technique, although a priori it seems not.

Labour day

Posted on by david

Sorry, this post has been translated using google translator. Click here for the original version.

Today is a time to stop and think about the rights of workers.

The origin comes from a working class exploited, receiving well below that generated. Not only could jeopardize. They demanded that their rights were satisfied. The workers were no longer so and were gentrify. Were able to mortgage and become homeowners. The financial world has evolved s’hipotequessin get much higher than originally and they had become slaves again.

Despite knowing that the more efficient is that everyone sees their contribution rewarded, we are convinced that this is not nor should be. We believe the proposals we have in and do what unions have done today: paste sticks blind. So do a number of proposals, inviting reflection.

Retirement based on the number of children. The public accounts are exhausted and can not be used to stimulate the birth rate. Well see that each day’s work rewarded when they performed their work day ends with a better retirement and the opportunity to devote to grandchildren

Days of 35 hours. Unemployment has reached a level inassumible and should make the maximum number of people no longer receive subsidies floated. So perhaps we can better educate our children and spend the evenings in activities so that they understand the world better. If we leave the world worse than what we found, at least we can teach to do better. Or be ourselves.

Withdrawal of power to lobbyists. Think we’re in their hands will not bring more than unfortunate.

Let us bubbles and pyramids. The next time that an investment in debt, that is not speculative, but goods equipment or training.

That politicians will have to inform the ROI of each investment they make and they do. We are interested in knowing why priority is the AVE Madrid-Valencia line merchandise Alicante Perpignan.

We dominated most of the language (as a country that wants to be post-industrial), mastered English and most people have more fourth and fifth languages, which must be as diverse as possible. Today, Norwegian, with less than 5 million people, someone will solve more problems than Spanish, with less than 500 million speakers.

Promoting the knowledge society. Clearly reward the effort and talent and set aside to be a territory with fewer clouds, we live from tourism (please!).

More solidarity. We must support the entrepreneur. If our neighbor creates a business, we think that if it goes well, better for us, although we hope things will go worse than us. And conversely, if it has not gone well, we admire his determination and support it because I try again.

I want to be a civil servant

Posted on by david

Sorry, this post has been translated using Google Translator

In universities know very well: about half of the students would be civil servants. I wonder if the parents do not want to be, many will feel better knowing that their children will end up being. I remember a movie (Father of the Bride) where the protagonist bothered him that his future son in law was an external consultant, as if it were not able to work in a company, as he had always known.

But both the nineteenth-century concept of the servant as the value of the contract to the low durable solutions for displaced people are being adapted to the dynamic economies that we need if we want to maintain the desired level of consumption (and pay the debts of the past decades).

So the career becomes a stimulating career background, where we’re all invited. It is not sustainable the dilemma of “official or private business.” Just hold the dilemma of “continuous assessment or professional entrepreneur. Companies are not being able to take charge of training all employees, is an overload that does not correspond. This does not mean not having to fund the training of workers, on the contrary, should the private company who replaced the public universities in training as professionals.

Personal Branding

A task that we must learn it from schools is to promote personal brand. Learn to express what we can offer in a complex business card which certifies our capabilities. Like everything, is to cultivate a habit and never lose sight of. The thing is as each. As there is no magic formula for time management, maintenance of performance at work or reconciling work and family life, there’s not that.

Careful of our web presence is undoubtedly a key factor. Many businesses before looking further down the CV header prefer for us to start the google and even less work, such as facebook.

Keeping our network of contacts is also important and complementary to demonstrate our value to the workplace every day.

It is paradoxical that these attributes as primary (we are promoting the survival of the fittest and focus on our social dimension) whatever they have to help us prosper, but perhaps we did not build fantasies (permanent and contract staff) have shown that should have never existed?

Memory Management

Posted on by david

Sorry, post translated using google translator

In the movie “The Social Network” are a couple of times very technical. It is used to enter the resource in times of difficult to understand because people understand how smart is Mark Zuckerberg (99.98% more than in the rest of the population, according to the American SAT), not because it understands content of what he says.

The first stage is one in which Mark Zuckerberg download photos of all the fraternity Facebook. If you are not in the discipline (web development) do not understand, and if a saint, you need a very high level of spoken English, as Jesse Eisenberg, at least for me, is pretty Duret.

The second time was in class, where talk about memory management. This is a subciència of computer architecture that consists of giving computers the ability to offer more memory than is actually using the hard disk storage. The problem says:

The system uses one-level page tables, which starts at 0×400. [...] [...] 16-bit system we assume that the page table entries are 8 bits of state. The 8-bit status would be … Someone?

Mark Zuckerberg’s answer is:

A valid bit, a bit changed a bit and 5 reference permission bits

The professor answered, or not rejoice that the answer is correct.

What does this really answer?

When the system wants to access a page (which is what divides the information), this is the physical memory (that we bought and it is one of the two most expensive things on the computer) or virtual ( disk). The page table says, given an address, under what conditions is the page.

Valid Bit

He says if it is cached or not. That is, if to do so lengthy that page, ie, scratch disk drive and turn on the light.

Bit changed

He says if the page has been changed to physical memory. This means that if necessary to occupy the space with other information, you must write what is your backup disk. If you’re not, no scratch disk (UEEEE!).

Bit reference

He says if someone has used this site part of the process that created it. If there are references. It is good to know if better or worse candidate to move it to disk, for example.

5 bits of permission

With 5 bits are allowed up to 32 possible combinations to build. However I only n’acudeixen 8: not watching it, just look at it, just write it, watch it and write, also run, just run, or are looking to write and run without looking. 4 bits are needed. Why you can use a 5-bit? This is already something of what system is used to manage memory, one possibility is to use it as permission to move to disk “(sticky bit) or” permission for a fallback “as a protected mode, for example.

Perhaps this could tell us the last llumenera of Mark.
