This is how Ech works, the Technological Shield of Cloudflare that has put the operators between the sword and the wall

by

The LaLiga fight against illegal soccer broadcasts It has encountered an unexpected obstacle: Ech (Encrypted Client Hello), an encryption protocol that stars in the great conflict and the collateral damage of this battle, which splashes thousands of companies. Turning point. It all started when Cloudflare implemented in October 2023 (Encrypted Client Hello), an extension of TLS that prevents operators from identifying which specific domain is requesting the user. This protocol makes it technically impossible for operators to see which specific domain requests a user. The contrast. ECH works as an additional encryption layer that completely hides the final destination of a connection: When a user tries to access a website, his browser initiates an encrypted “negotiation” (Handshake TLS) With the server. Before ECH, although this connection was encrypted, the name of the domain was traveling “in clear” so that the intermediate servers could enrut the traffic. With ECH, the name of the domain is also encrypted, making it impossible for the operators to know which concrete website the user is accessing. The system is even more complicated because Cloudflare uses shared IPS: The same IP address can house hundreds or thousands of different websites. Without ECH, the operators could see what domain each user requested and block selectively. With ATU activated, they only see an encrypted IP that could be serving both legal and illegal content. This leaves two options to the operators: block all the IP (affecting hundreds or thousands of sites) or not blocking anything. When they choose the first thing the Blocked legitimate websites. To avoid blockages, which also translate into a reputational crisis, some operators are resorting to alternative techniques such as: Traffic patterns analysis. Deep inspection of packages (DPI). BLOCK BY SNI (Indication of the server name) when ECH is not active. But these solutions are complex, expensive and not always effective. The conflict has climbed, Movistar has softened his blockages, Digi has hardened them and Vodafone says to have a more precise solution although it has not revealed details yet (since Xataka We have asked them for this without having received an answer at the time of publishing this article). They possibly use one of the last points. The next. Ech has supposed a huge change in Internet architecture. The precedent of Austria, where IPS blockades were prohibited To protect the neutrality of the network, it suggests that the current regulation model needs to adapt to this new reality. Meanwhile, the pulse between LaLiga and Cloudflare persists, and thousands of Spanish companies also remain trapped in the midst of the conflict.

They prefer to work in a hospital than in a great technological

The labor market has not finished leaving the storm caused by the Generalized Teleworking Implementation and the subsequent movements of the companies to make their employees return to officeswhen you must face a new challenge. A study Made in the United States by the National Society of Hight School Scholars (NSHSS) has revealed the first signs of tired of generation Z with the Labor dynamics of the technological sector. The data suggest that, given a future marked by the arrival of AI, young people prefer to study careers related to the health or welfare scope, leaving aside the computer races or certain engineering. A sector at risk. Prominent voices at the head of large companies, Like Nvidia or aws, They have assured On different occasions that AI will make the engineers unnecessary know how to program. Technological profiles are expected to be the most sensitive to Automation Impact As companies begin to implement AI, which shows a bad expectation for the future for the sector. In addition, the job instabilitywith hundreds of thousands of annual layoffs in large companies, and their high rotation, it remains attractive to a Z generation that seeks economic stability for its future, such and as revealed The consultant’s survey What’s The Big Data. Generation Z prioritizes job stability. According to collected data By Networks Trends about a sample of more than 10,000 US students, 76% of the young Z generation who are graduating in universities prioritize a stable work careerabove the location of the company (75%), its reputation (72%) and even the possibility of obtaining a high salary (71%). 50% of respondents say they are very concerned because, after years of study of a career they like, the incorporation to A toxic work environment take them to suffer burnout or have trouble developing their career. With that fear in mind, many of the students have reduced their interest in great technological ones, which no longer offer the idyllic job environments years ago. Great technology are no longer preference. According to The study From HSHSS, newly graduated students are prioritizing working in companies in the health or welfare sector, instead of in the great technological ones that had been leading the listings of better places to work for years. According to these data, Google has gone from being the fourth company in which students would like to work in 2022, to occupy the seventh place on the list in 2024. Just behind we find Amazon and Apple, which have also fallen several positions. Companies like Spacex have fallen from the ninth place to the twenty -second. The trend also reaches Spain. Although at a slower pace, the change in trend in the election of careers, the branches of the field of health and social services have registered a significant increase between 2018 and 2024, as reflected in The study ‘Employability of young people in Spain of 2024’ prepared by the CYD Foundation. Computer and engineering careers continue to have A very important weight In the election of the students, but the careers of Medicine and Nursing have registered a very prominent rebound, although the report highlights that it is one of the sectors with the greatest temporality. Spain ages: sanitary ones are needed. He demographic aging In Spain it is one of the reasons why this health sector has grown 4% in the last year and faces a generational relief process given that, According to data Randstad, 40% of employees in this sector are over 45 years old. That is, unlike the technological that tends to specialization and automation, the health sector tends to need more personnel and with a low exposure to the impact of AI.

Just take a look at the list of greater fortunes of the world to realize that, in one way or another, AI is the common denominator that has catapulted these fortunes at current levels. However, the earthquake caused by Deepseekhas caused investors to doubt the real value of the projects supported by large technological ones, which has picked up the value of their actions, dragging with them the fortunes of their CEOS and founders. Specifically, Fortune esteema joint loss of more than 108,000 million in a single day. It is not the first time This happens. Jensen Huang and Nvidia in the eye of the hurricane. The news that the new China has not used the most powerful processors Nvidia for its development has made the market assessment of the Jensen Huang company lost 400,000 million dollars. As a result of that fall, the Jensen Huang fortune He lost a value of 20,100 million dollars in just one day, which represents 20% of the total fortune. Larry Ellison’s infrastructure. Much of Oracle’s success in recent years has been based on the structure offered for AI, So it is not surprising that investors have also staged their doubts selling their positions in the company that founded and directs Larry Ellisonwhich currently occupies the fifth place among the greatest fortunes in the world. Percentage, the New York millionaire lost less than Huang with 12% of his fortune, but in absolute terms, Oracle’s fall after the presentation of Deepseek caused him a devaluation of his fortune estimated at 22.6 billion euros. Collateral damage of the fall. Together, technological giants lost about 94,000 million directly due to the depreciation of their market value due to the mass sale of shares. This fall caused an expansive wave in other indices that, indirectly, also suffered losses. The Nasdaq index 3.1% fell and the S&P 500 left 1.5%. For example, Michael Dell’s fortune, the computers giant13,000 million were left after the presentation of the new Chinese model, while the co -founder of Binance Holdings, Changpeng “CZ” Zhaolost 12,100 million dollars. Immune to earthquakes. Although the Deepseek’s emergence It has meant a tsunami for the AI ​​development scene, some leading actors seem to put their fortunes in dusty and left unscathed from this stock market shaking. The biggest beneficiary has been Bernard Arnault, who has known Fishing in a scrambled river Adding 5,000 million dollars to their fortune while most technological millionaires painted their negative balances. Worthy of a teacher in stock jarism has been the role of Mark Zuckerberg, who has not only unharmed the tsunami that has caused China, but has added 4.2 billion dollars to his fortune. Jeff Bezos, with a more discreet role, has added 519 million, but like Zuckerberg, he has fallen to the storm being one of the main investors in the development of AI.

A study reveals which technological profile will be the most sought after and best paid in 2025: interface designer

by

Choosing the right career at the right time can be the key to building a successful, well-paying career. Like every January, the employment platform Adecco presents its Adecco IT & Digital Salary Guidewhich analyzes the technological professions with the greatest demand forecast and, more importantly, with the best remuneration for non-managerial positions. That is, salaries between 35,000 and 45,000 euros. A technological engine. According to data from the study, the technology sector in Spain is boomingand already contributes 24% to the national GDP, although this percentage also includes technological activities derived from the digitalization processes of other sectors such as agriculture, industry or the services sector. Adecco assures that the IT sector has generated 26,267 new affiliates in the last year, and the professionals with technological profiles They are the most demanded by companies, ranking among the top five in autonomous communities such as Andalusia or Catalonia. UX Designers, the most in demand. The Adecco study points out the rise in demand for specialized professionals in the design of digital interfaces or UX/UI Designers. This profile is responsible for designing the way in which users should interact correctly with digital products, whether web pages, application interfaces and even the use menus of digital kiosks or sales terminals. Adecco also highlights the high demand that Customer Experience Specialist profiles, SEO/SEM experts, Social CRM Managers or Traffickers who are in charge of planning online advertising campaigns will have. And the best paid. In the salary estimate that Adecco makes in its study, two business scenarios are considered depending on whether you are going to work in a large multinational company or in an SME, and it classifies it into three scales conditioned on experience in the sector in ranges of three. , five or more than 10 years. A user interface designer with more than 10 years of experience is estimated to have an annual salary of around 49,000 euros gross if he works in a multinational, and 45,000 euros per year if he works in an SME. The place of residence matters a lot. Something that the salary ranges estimated by Adecco show is that the salary amount is not only influenced by working for a large multinational company or an SME, there is also a large salary gap depending on the autonomous community in which the job offer is created. We have already mentioned that a UX/UI designer can charge between 40,000 and 49,000 euros per year depending on the type of company. That would be if the job were in Barcelona. In Madrid, the same position would lower its salary range to between 35,000 and 40,000 euros, while, in Murcia, the salary for that position would plummet to a range of between 25,000 and 20,000 euros. A substantial difference for the same professional profile. Web designer, in an SME and in Murcia. The worst salary option in the table is found in the salary profile of web designers who are going to work in an SME in Murcia. The data foresees a salary range of 18,000 euros gross per year, and 20,000 euros for web designers who work for a multinational in that community.

China is very clear about what it has to do to free itself from US pressure: achieve technological self-sufficiency

by

The geopolitical scenario in 2025 is, if possible, even more uncertain than in 2024. The two protagonists are unquestionably USA and China because they are the two great powers that are disputing world supremacy. And each one of them leads a side with notable allies with whom it shares an evident alignment in the economic, technological and military fields. China’s technological development has been deeply conditioned for more than two years now by the sanctions that the US is deploying and his allies. These bans primarily seek to stop the development of China’s semiconductor industry, but their implications reach many other industries due to the omnipresence of chips, such as the military, robots, electric cars or telecommunications, among others. others. China needs to achieve technological self-sufficiency at any price China’s medium-term economy is at stake. And the world leadership for which it competes with the United States, too. The Government led by Xi Jinping is fully aware of how important it is for its country to put an end once and for all to the dependency that still exists today of many foreign countries from a technological point of view. Precisely this dependency has been taken advantage of by the US to prevent Chinese integrated circuit manufacturers from accessing the most advanced lithography equipment it produces. the Dutch company ASML. “By managing our own affairs well, we can promote the stable and healthy development of China’s economy.” This is the situation in which The Chinese Administration has promoted the holding this Monday of a meeting in which the country’s political and social leaders urged industry executives as a whole to dedicate your resources to the technology sector. Its dual purpose is to materialize new engines of economic growth and promote China’s technological independence under the leadership of the Federation of Industry and Commerce, which will be the institution that will guide the private sector on this path. “By managing our own affairs well, we can promote the stable and healthy development of China’s economy,” has declared Premier Li Qiang. During 2024, the gross domestic product of this country has grown by 5%, and several intensely industrialized regions, including Zhejiang province, aim to grow by at least 5.5% during 2025. The fact that the meeting among Chinese leaders was celebrated on the same day that Donald Trump has returned to the White House It has a marked symbolic character. A fact that is worth not overlooking is that at last Monday’s meeting, in addition to the political and social leaders of China, several very prominent people participated. from the field of science and technology. One of them was Liang Wenfeng, the founder of the investment company High Flyer Quant that backs the startup of artificial intelligence DeepSeek. Wei Hongxing, founder of AUBO Robotics Technology, also participated in this event. What is still not entirely clear is how China is going to act in the face of a probable escalation of the tariffs imposed by the US under the mandate of Donald Trump. We probably won’t have to wait long to check it out. More information | SCMP In Xataka | Historical record for China: its chip industry has produced more than ever in 2024 despite sanctions
