Big Tech do not stop saying goodbye to their engineers. In parallel, they have stepped on the accelerator in the hiring

by

The labor market for software engineers in 2025 is going through A disconcerting phase. While many companies are running Great rounds of layoffs And vacancies take longer to cover themselves, the great technological have stepped on the accelerator in their hiring registering a moderate increase in recent months. With the aim of understanding this phenomenon, Gergely Oroszengineer, analyst and author of ‘The Software Engineer’s Guidebook’ has crossed data from different technological employment platforms to offer a detailed analysis of the labor market in 2025. The result shows a panorama in transformation, in which traditional rules seem to have changed and Big Tech movements point to a future very marked by AI. Boom in layoffs, but also in hiring. Just check quickly The newspaper library recent to discover that technology companies are executing Dismissal rounds In his templates. According to dataFrom the Trueup platform, in what we have been counted about 141,000 dismissals Among the great technology. The estimates are that 2025 closure with 210,000 layoffs that, despite being many, are below the 430,000 layoffs that were recorded in 2023 or 239,000 of 2024. Dismissal figures in the technology sector However, those same companies are the ones that are most hiring in recent months, registering a Mild up rising trend in the total of new offers in the labor market. The reason: these layoffs are not due to economic difficulties, but because companies have changed their business goals and are reorieting their templates. Companies such as Apple (2,177 vacancies), IBM (1,924 vacancies), Amazon (1,794 vacancies) and Oracle (1,394 vacancies) are the ones that have registered the most vacancies, according to the data revealed by Orosz. Zuckerberg has taken the wallet. In case the latest movements of Millionaire signings in AI They leave a doubt, goal is the company that is hiring the most engineers, with an increase of 19% compared to its 2022 template.Google and Apple show a somewhat more leisurely rhythm in hiring, although they increase their templates with new hiring at a rate of 16% and 13% respectively with respect to 2022. Amazon and Microsoft later began their Pivotage to AIand their figures are maintained below 8%, although the last restructuring movements Of both companies, they point out that, in the face of the last quarter, that percentage will tend up. Who is hired. Big Tech are immersed In a race For immediate profitable Investments in AI. So the profile that is being demanded most is the IA engineer profile that, According to data In Trueup, it has increased by 278.5% since its lowest point in 2023 and currently has 24,957 vacancies open. The hiring data also reveal that the profile most demand IA -oriented specialtiesbut they are the engineers who already have a certain experience (with 27,864 vacancies available) or already with a senior profile (with 22,477 published employment offers). Orosz’s analysis data reveal that the seniors engineers of ia will cover those vacancies, They will leave Big Tech Consolidated such as Google, Meta, Apple or Microsoft, joining projects in the new heavyweights of AI such as OpenAi, Anthropic or XAI, as well as other emerging unicorns. The AI ​​recover the work remote and sacrifices the bosses. According to data published by Orosz, the volume of offers of remote employment has fallenRegarding the previous year. However, the exception of the brand again the engineering of AI, where the urgency to recruit talent causes a relatively high number of vacancies to be maintained with the possibility of remote work. In parallel, the leadership positions in engineering are seen increasingly limited. Amazon has significantly reduced the engineering managers roles. For its part, almost all Big Tech – with the exception of Apple— They have trimmed the creation of positions of director or intermediate positions. This adjustment responds to a reorganization of internal structures, such as the one that has launched Googlethat prioritize smaller and agile equipment.

The Granada particle accelerator is born today. Thanks to him Spain has the key to nuclear fusion

by

Today is a crucial day for IFMIF-DONES (International Fusion materials irradicion facility demo-eraned neutron source). This very important scientific project is closely linked to ITER (International Thermonuclear Experctor reactor), The experimental reactor of nuclear fusion that An international consortium led by Europe He is building in the French town of Cadarache. Ifmif-Dones, however, resides in listening to, a town in the province of Granada. The construction works of this last installation began in mid -September 2022, but today it is a very important day for both Granada and all of Spain. And it is because the Council of Ministers will approve today the investment of almost 200 million euros required by the start of the construction of the IFMIF-DONES linear particle accelerator. This machine is the authentic heart of this scientific installation, and, therefore, the ingenuity that will place Spain in The nuclear fusion map. The tuning of this linear particle accelerator will cost approximately 450 million euros, although the Andalusian Board will contribute half of this money. However, this is the cost of the accelerator; The IFMIF-Dones project will completely cost about 700 million euros. Spain will contribute half of this capital. To this figure we must add another 50 million to carry out its implementation. In addition, the operation of this avant -garde research center will have an annual cost of about 60 million euros, of which Spain will assume 10%. It may seem a lot of money, but we must not forget that those responsible for the project are convinced that The economic and scientific return Ifmif-Dones will far exceed your cost. What is Ifmif-Dones and why it is crucial for the future of nuclear fusion Ifmif-Dones is one of the three fundamental pillars of the nuclear fusion building in whose construction the European Union is involved. The other two are iter and demo. The experimental nuclear fusion reactor that is currently being built in the French town of Cadarache seeks to demonstrate that the merger at the scale that man can handle works, and also that it is profitable from an energy point of view. However, Iter does not aspire to produce electricity. That will be demo’s task (Demonstration Power Plant), an installation that will take the technological advances that will have shown to function correctly in Iter and take them one step further to establish themselves as The authentic precursor of commercial nuclear fusion reactors. However, without Ifmif-Dones there will be no demo, so Granada is now the center of attention. The fusion of a deuterium core and another tritium triggers the production of a helium core and a neutron that is fired with an energy of about 14 MEV To understand in all its extension what is the role of the IFMIF-DONES project, it is necessary that we briefly review the foundations of nuclear fusion. One of the biggest challenges facing the technicians who are involved in the tuning of nuclear fusion reactors by means of magnetic confinement, such as Iter, consists of recreating inside the vacuum chamber of these sophisticated machines the necessary conditions so that the deuterium and tritium nuclei are merged. However, this is not everything. When this reaction takes place the fusion of a deuterium nucleus and another of tritium triggers the production of a helium core and a neutron that is fired with An energy of about 14 MEV (Megaelectronvolts). The problem is that the neutron lacks net electric charge, so it cannot be confined inside the magnetic field that, however, does retain the deuterium and tritium nuclei, which have positive electric charge. This is the reason why when it originates as a result of the nuclear fusion reaction, this neutron is fired towards the walls of the vacuum chamber with enormous energy. This particle is very important because in practice it will be closely linked to the production of electrical energy in nuclear fusion reactors, but, at the same time, it represents a very aggressive form of radiation that can significantly degrade the materials used in the reactor. The components that will be most affected by the direct impact of high energy neutrons and the most intense heat flow are the internal wall of the vacuum chamber and the Blanketthat it is a mantle that covers it and that has as its purpose Regenerate the tritium that it is necessary to use as fuel in the nuclear fusion reaction. This is the reason why it is crucial to develop new materials that are able to support the flow of neutrons and guarantee, therefore, that the reactor will have a prolonged operational life. IFMIF-DONES linear accelerator will produce high energy neutrons with the intensity and volume of irradiation necessary to test candidate materials This is, neither more nor less, the purpose of Ifmif-Dones. And to carry it out it is necessary to put ready -to -set facilities to allow the technicians involved in the project to evaluate the properties of candidate materials to intervene not only in demo, but also in future commercial nuclear fusion commercial reactors. The task of this project invites us to intuit what the heart of Ifmif-Dones is: a source capable of producing high energy neutrons with the intensity and volume of irradiation necessary for Test candidate materials. And this source of neutrons will be nothing other than a linear particle accelerator that will help IFMIF-DONES scientists to try, validate and qualify the materials that in the medium term should reach future electric power production plants through fusion.

FNAC Pisa the accelerator to return to profitability

by

FNAC changes their strategy: it will recover its emblematic Callao store in September of this year and plans Five days. Why is it important. After playing fund in 2023 with its first losses since its arrival in Spain three decades ago, the French company of cultural and electronic distribution needs to demonstrate that it can prosper in a post-pondemic market where consumers have changed their purchase habits. The pandemic hangover. The boom in the demand for electronic products during confinement triggered FNAC sales to 365 million in 2021, according to the figures declared by Guillem. The subsequent collapse was abrupt: in 2023 its income fell to 307 million, 16% less, going back to 2004 levels, as explained by the director. The way to recovery. 2024 marks the start of the comeback with a modest growth of 2% in sales. “Finishing the year growing in sales and results is very good news,” says Guillén, who acknowledges that “three years experimenting with the store models to build the FNAC of the future.” The commitment to origins. The new strategy combines tradition and modernity: Promote personalized advice, sign of historical identity of the brand. Rationalize the assortment in physical store: “We do not need to have everything exposed.” Maintain cultural strength: same spaces for books and music. Provide the tools personnel directly, eliminating queues. The goal. FNAC will allocate 6 million euros to the renewal of Your flagship store in Callaowhich will go from 7,000 to 4,000 square meters, optimizing the space for 70% to be a commercial area. The Plan plans to update up to four establishments per year and open new from 2026. The French has marked the 400 million billing by 2027 – it does not reach since 2012 – and expand her network of stores, pass the current 36 to 50. “The idea I have in the head is to reach 50. If we want to remain strong in Spain we have to continue growing,” explains Guillén. Between the lines. The real challenge is not in turnover, but in profitability. FNAC seeks “more profitable” stores before larger, betting on operational efficiency and differential experience against digital competitors and large surfaces. The reduction of space in Callao without giving up its role as a cultural reference is an example of this new philosophy. And now what? Callao’s reopening in September will be the first major test for this transformation plan. The success of FNAC will depend on its ability to execute that difficult balance between cultural tradition and commercial modernization. And of backdrop, an increasingly complex sector.

Openai steps on the accelerator in the AI ​​race with its new and advanced language model

by

The career for the development of artificial intelligence does not stop accelerating. In November 2022 we witnessed the launch of GPT-3.5the model that laid the bases of Chatgpt and marked a turning point in the The conversational. Almost two years later, we are facing the arrival of GPT-4.5a new evolution that aims to continue expanding the limits of this promising technology. We are facing a transition model between GPT-4O and GPT-5, but with a key role in OpenAi’s strategy. The company has decided that GPT-4.5 will be the last without incorporating “chain of thought”, giving way to a new generation with incorporated reasoning capabilities. This change seeks to improve the clarity of your family of products, that has become complex over time. A more advanced model, with greater emotional intelligence AI is reaching a point where we no longer settle for having models capable of solving complex problems. That improve in programming, science, engineering and mathematics is very good, but we look for models that can interact with more spontaneous way With humans. This makes us understand OpenAi with GPT-4.5. His new language model is presented as the greatest and most advanced published by the startup to date. The researchers affirm that it is not only more natural, but their knowledge base has expanded to face complex challenges in various scientific disciplines, while improving their ability to solve logical problems. GPT-4.5 wants to stand out for its emotional intelligence, and in a recent test it has proven to live up to it. A member of the OpenAI team tested his abilities by sending him a message full of emotion. With a natural tone and Without hiding your anger, He explained that a friend had canceled him at the last minute and asked for help to write a message that reflected his discomfort. Chatgpt with GPT-4.5 detects that the user is frustrated and, instead of enlivening the anger, he suggests a calmer and diplomatic message to express his discomfort without damaging friendship: “Hello, the truth is that it has annoyed me a lot that the plans have been canceled again, I really wanted to see you. Can we talk about what is happening?” To achieve this change, Openai has modified its focus on creating models. Not radically, but incorporating New supervision techniques Together with traditional methods such as the fine supervised adjustment (SFT) and learning by reinforcement based on human feedback (RLHF), which were already fundamental in the development of GPT-4. In development. Images | OpenAI In Xataka | Alexa+, first impressions: the explosion of AI feels great to the Amazon assistant. But there are also many unknowns

Goal approaches 100,000 million invested in metoverso, and has no intention of raising the foot of the accelerator

by

More than ten years have passed since Mark Zuckerberg announced the purchase of Oculus And he began to profile his idea of ​​’Metaverso‘, although the concept did not gain prominence until 2021, When Facebook, Inc. was called Platforms goal, Inc. Reality labs, the division that promotes this initiative, is on the way to burn 100,000 million dollarsand everything indicates that there is still a long way before those promises of incredible virtual worlds, where to work, play and socialize, come true. Virtual and mixed reality glasses, such as Quest Pro goal, Quest 3 goal either Apple Vision Prothey are the entrance door to this type of experience. However, these devices are not yet powerful, light and affordable to gain ground in the general public. A reflection of this reality is Tim Cook’s statements last year, when Apple’s CEO recognized that their glasses are “an early adoption product” intended for “people who want to have tomorrow’s technology.” Goal continues to burn money in metaverso Between 2014 and 2024, Meta has invested more than 80,000 million dollars in its virtual and augmented reality ambitions. The data comes from your financial ones that reflect an expense of 19,875 million dollars and a benefit of 2,146 million dollars to throughout the last year. In other words, the reality Labs division closed 2024 with losses of 17,729 million dollars. Far from lifting the accelerator’s foot, the giant of social networks remains convinced that this is the way, so he anticipates a 2025 with more investment and more losses in reality labs. Few companies in the world can afford with such long term. Meta, of course, is one of them: in 2024 he recorded net profits of 87,109 million dollars in family of apps (FOA), the segment that encompasses products and services such as Facebook, Instagram, Messenger and WhatsApp. Although reality labs is closely linked to metoverso, its reach goes much further. Immediately, this division is the epicenter of commercial products with relative successlike the family of target quest glasses and Ray-Ban Metadeveloped in collaboration with Essiloruxotic. But it is also the laboratory where the future of the company is being built. Last year we first saw Oriona prototype of augmented reality glasses that, According to Zuckerberg himselfit could one day replace the smartphone as we know it. At first glance, Orion glasses are more bulky and robust than the finish lines, probably due to the internal components necessary to project images. And they integrate micro LED projectorscapable of superimposing information in the real world. The idea is to use the physical environment as a canvas for 2D and 3D apps. But there is more. Reality labs is working on the powerful, light and affordable glasses that we mentioned at the beginning. And that, of course, requires a lot of work. At the visualization level, the objective is to achieve a practically indistinguishable experience of reality. But it is not enough with high resolution screens in next -generation glasses, but it is necessary develop technologies that still do not exist to adapt to the complex human visual system. In addition, projects include the exploration of new interfaces, such as electromiography based, which allow controlling devices through neuromuscular signals. As the company itself recognizes, its bet is to develop products that we will not see soon, but will reach its maximum splendor “in the next decade” It will be necessary to see if this goal is still standing with the advance of artificial intelligence (AI), a field in which Meta is investing billions and that, at some point, converges with its vision of metavers.
