That WhatsApp devours my mobile memory is a thing of the past. These are the three habits I follow to avoid it

by

Running out of memory on our mobile is quite common and many times The culprit has a name: WhatsApp. With more than 3 billion usersis the undisputed queen of messaging apps. Everyone uses it, which means receiving hundreds of messages, photos, videos and audios through WhatsApp, making The size of the app increases exponentially over time. It’s happened to me too, but for years I’ve been able to keep it at bay by following these habits. Automatic download disabled If you haven’t done it already, it’s the first thing I recommend and you will only have to do it once (unless you change your mobile phone). The option is within WhatsApp in Settings – Storage and data – Automatic file download. By default, WhatsApp downloads all the photos they send us. For the rest of the files such as audio or videos, it only downloads them when we are connected to a WiFi network to save mobile data. The only ones that always download, whether you like it or not, are voice messages. If you want to control storage space, my advice is to change all options to ‘never’. This does not mean that you cannot see the photos they send you, you can do so but first you will have to download them. It’s adding one more step, but like this you can choose which ones you want to see and which ones you don’t. It is useful, for example, if you are in groups that send a lot of files, but you are not always interested in seeing them. WHATSAPP Tricks and tips to HIDE YOURSELF TO THE MAXIMUM and maintain your PRIVACY Delete multimedia content from time to time Even though automatic download is limited, I still download many of the photos and videos that my contacts send me, so the storage is increasing. Every so often I manually delete multimedia content that I have been receiving. WhatsApp has a very useful section to do this in Settings – Storage and data – Storage manager. I do two things here. The first is to access the section where the files that are larger than 5MBgenerally videos, and I delete those that I don’t want to keep. Here you will also see videos that you have sent yourself and that sometimes appear duplicates (this is because you have sent them to several different chats). When you have selected them, click on the trash icon (bottom right). The second thing is to go to the section ‘Storage details’, where you’ll see a list of all your chats ordered from the one that occupies the most size to the one that occupies the least. Entering one by one are all the files, also ordered from largest to smallest size, and I delete those that I am not interested in keeping. The storage you free up It will depend on how many files you are willing to delete. In my case, except for specific things, I don’t have much attachment to the content I share on WhatsApp and sometimes I delete everything at once. Review channels and groups that I no longer use Let them put us in WhatsApp groups for everything It is quite common. Personally, if I’m not interested or the group no longer makes sense (for example, if it was created for a specific event and has already expired), I leave and delete the entire chat. To leave a group you can do so from the chat list by holding down on it or, if you are in it, by clicking on the group name and choosing the ‘Leave Group’ option. You will see that two options appear, the one that interests us is ‘Exit and delete for me.’ Only then will the files and content that have been shared be deleted. With channels and communities I follow the same procedure. When it has stopped being useful to me for whatever reason, I quit. You can do this by entering the community you want to leave and clicking on the three dots icon in the upper right corner.

The bad thing about Framework Desktop is that it has welded memory. Good too

by

In 2021 the portable panorama was bleak in a key section: The right to repair. Manufacturers made it more difficult to try to solve problems or update these machines. It was then that a small and unknown company He showed us That there was an alternative. That company was called (and is called) Framework. Their Modular laptops have since demonstrated being An absolute reference in repability and expansion capacityand in recent years they have maintained that tradition. A few months ago they advanced the launch of Two new portable modelsbut next to them a surprising machine arrived: a desktop minipc that, curiously, seemed a betrayal to the principles of the company. That machine is none other than the Framework Desktopa different team both for its exterior and its interior. To start, we are talking about a minipc format equipment with a mini -it plaque and a tiny box with a volume of 4.5 liters. That box also has A differentiating design With a front panel in which we can place 21 “tiles” that we can also customize by printing them in 3D ourselves (The designs To do so they are available). The team also presumes from those already famous modular ports in their laptops and that allow to create a tailored inputs and outputs. We can buy them separately and incorporate new modules when we need it. That in regards to the outside. Inside, the technical specifications are as follows: Framework Desktop Processor AMD Ryzen AI Max 385 (8 cores, 16 threads, up to 5.0 GHz, soldier) AMD Ryzen AI Max+ 395 (16 cores, 32 threads, up to 5.1 GHz, soldier) GPU Radeon 8050s Graphics (32 nuclei, 2.8 GHz) Radeon 8060s Graphics (40 cores, 2.9 GHz) NPU Up to 50 tops Memory 32/64/128 GB LPDDR5X-8000 Welded Storage Flexatx 400W Front ports 2 x customizable I/O modules Rear ports 1 x HDMI 2.1 2 x Displayport 2.1 2 x USB-C (USB4) 1 x RJ45 (5GBE) 2 x USB-A (USB 3.2 GEN1) 1 x minijack 3.5 mm Feeding Flexatx 400W Dimensions and weight 96.8 x 205.5 x 226.1mm 3.1 kg 4.5 L mini -it box Price From 1,309 euros In these specifications it surprises how we say we find a configuration in which the AMD soc (with the CPU, the integrated GPU and the NPU) is welded to the motherboard, but it is also the memory. That seems a betrayal to the “replaceable and replaceable” spirit of Framework teams, and is something that has already caused some criticism. A the AI workstation for all audiences Some of the analysis Independents who have evaluated the team criticize him for that. However, that decision has its reason for being: as the company responsible explained in the Official announcement: “To enable the huge 256 GB/s memory bandwidth offered by Ryzen AI Max, the LPDDR5X has welded. We spent months working with AMD to explore ways to solve this, but finally we determine that it was not technically viable to install modular memory with high performance with the 256 -bit memory bus.” It is a reasonable argument, especially considering that although this team has a certain gaming personality, its true focus is another. These teams make use of a unified memory architecture (UMA) That makes no dedicated video memory: the GPU uses RAM as video memory, so 32, 64 or 128 GB of RAM are shared between CPU and GPU. It is an idea similar to the one handled by Apple in its MX chips: there the unified memory allows to be used interchangeably by the CPU or the GPU. And there is the interesting thing about these machines, which are in essence affordable work stations to work with local AI models. We already talked about this week of how GPT-Oss-20b, Openai’s open model was great but showed that having a lot of graphic memory was important for this type of scenarios. Well, Framework Desktop raises a decent alternative to Apple teams and their unified memory. If, for example, we buy the 128 GB model of RAM (2,359 euros), We could dedicate up to 112 GB of those available for video memory. That gives a lot of play to work with heavy models such as the “Large” variant of Openai (GPT-Oss-120b) or, as they explain in Framework, with models as it calls 3.3 70b Q6, for example. In fact, that is where this team really provides value, which also maintains a low profile in terms of power (the consumption peak is 140W) and also in noise. We are not before a gaming team competitor with dedicated graphics: if what you want is to play every pill (even in Minipc format), this may not be the best alternative. But if you want, you are rather occasional gamers and what you are interested in is to have a powerful work team and allow you to experiment with local AI models, We are facing what is probably one of the best current alternatives If you are looking for a compact, efficient and silent team. The other options are clear: a high -end MAC with the maximum amount of unified memory that you can pay, or a PC in which you combine several dedicated graphics (to add their graphic memories) and that therefore will consume a lot of energy, it will be voluminous and predictably make a lot of noise. Could Framework Desktop have been a more modular, reparable and replaceable equipment? Definitely. But that is what are already the majority of current PCs. Here the manufacturer has taken another way, and we believe it is a very interesting approach. Now it will be the users who will decide (you will decide).

Not for pleasure, but because the intestine has memory

by

A year ago, every time I ate something, my belly swelled like a balloon. I felt heavy, with gases, uncomfortable. I did not understand what happened to me, until I tested positive for bacterial overgrowth in the small intestine or its short version, Sibo. I started an antibiotic treatment and a very restrictive diet. I left gluten, dairy, nuts, fruits … almost everything. And when it seemed that I finally felt better, the strangest part of the process came: I had to reintroduce some foods, little by little, as if it were a vaccine; but I did, I would become intolerant. Increasingly widespread. Increasingly widespread. In both medical consultations and conversations, surely the term Sibo (for its acronym in English, bacterial intestinal overgrowth) is no longer unknown. This condition describes an imbalance in the intestinal microbiota: bacteria that should be found in the colon end proliferating in the small intestine, an environment where they should normally be almost non -existent. This invasion causes varied and annoying symptoms, such as abdominal swelling, gases, pain, diarrhea or constipation, According to Mayo Clinic. It is estimated that up to 15% of the Spanish population suffers from it, and is more frequent in women between 30 and 50 years, According to the Spanish Society of Primary Care Physicians (Semergen). Its diagnosis has increased in recent years thanks to greater awareness and evidence such as the breath test, a non -invasive technique that measures the amount of gases produced by bacteria after ingesting carbohydrates. After diagnosis. It is followed by a low diet in Fodmaps, a protocol that eliminates the most fermentable foods to relieve symptoms. It is not a cure in itself, but it helps reduce gas production and abdominal discomfort while antibiotic treatment takes effect. The problem comes later. We talk to Jesús Guardioladietitian-nutritionist, to understand what happens in that critical phase: food reintroduction. “A low diet in Fodmaps should not be maintained in time because, when restricting so much, it can affect nutritional diversity and microbiota. But also, if you stop consuming certain foods for a long time, you can lose tolerance to them,” he explains. The intestine also forgets. Stop eating gluten does not cause celiacy. This is an autoimmune disease that only appears in genetically predisposed people. However, eliminating it prolonged can generate an unexpected reaction: that the body tole it worse when reintroducing it, Guardiola points out. This can go through several mechanisms: enzymatic (the body stops producing enzymes such as lactase, necessary to digest lactose), immunological (less exposure can alter the immune response), or by changes in the microbiota (bacteria in charge of digesting that food disappear). From Monash Universityin Australia, an institution that developed the diet has explained about these effects in prolonged restrictions can reduce functional tolerance and affect microbial diversity. But not a real intolerance. No, of course. The point is that it has been shown that eliminating food groups can alter microbiota and digestive capacity. The body needs gradual exposure to adapt, so the reintroduction must be done carefully and individually, According to the academic institution. “The key is to do it little by little, evaluating the symptoms, writing amounts and reactions. If you introduce many foods at the same time and something feels bad, you will not know what it was. And if you do it too fast, it is more likely that you can fall or that you suggest you thinking that it will sit badly,” Guardiola warns. The diagnosis of Sibo. The boom has also been accompanied by some controversy. Each time it is diagnosed more frequently, but not always with clear criteria: in many cases it is by discard, when other pathologies have been eliminated, and sometimes without conclusive evidence. This complicates the precise identification of the disorder, and can lead to confuse with food intolerances, functional disorders or, simply, with bad habits. From Semergen They have insisted that the treatment requires a comprehensive approach: not only medications, but also changes in the diet, lifestyle and analysis of the full medical history. To this is added an increasingly common problem: patients who adopt low fodmap diets on their own, without professional supervision, and who keep them for months or even years. Instead of improving, this can end up deteriorating even more intestinal health. What I learned during the process. Today I eat gluten again. I am not celiac. But I went through months of fear of food, not knowing if what I ate was healing or getting sick. I understood that there are no good or bad foods, but contexts, quantities and, above all, processes. Reintroduction is not just another part of treatment. It is a way to reconcile with food. And to understand that, sometimes, the problem was not bread, but how we stopped eating it. Sometimes healing means exposing yourself to what you thought you hurt you. In my case, yes: I had to inoculate gluten.

Chinese memory chips manufacturers are a nightmare for the US and South Korea. There is a lot at play

by

Yangtze Memory Technologies Co. (YMTC) is one of the largest memory chips manufacturers in China. Its quota in the global market is approximately 6%so it is far from South Korean companies Samsung and SK Hynix, and also from the American Micron Technology, the three companies that lead this sector. Even so, Its weight in the Chinese market is very largeespecially because US sanctions They prevent American and South Korean memories manufacturers selling their most sophisticated integrated circuits to their Chinese clients. YMTC is in the spotlight of the US administration for more than two years. In fact, at the end of 2022 the Department of Commerce led by Gina Raimondo He decided to include this company in his blacklist because he had managed to develop an ambitious 128 layer memory chip. Currently YMTC is one of the companies that have the most advanced semiconductor manufacturing technology in China, and curiously, According to Techinsights He has reached this position without resorting to foreign technology. Not even Asml’s. YMTC aspires to intimidate the leaders of the memory chips market This achievement seems to have been possible because YMTC has the complicity of three of the most important Chinese lithography equipment: Naura Technology, Amec (Advanced Micro-Fabrication Equipment Inc. China) and Piotech Inc. The most shocking thing is that according to Techinsight analysts, which is a Canadian communication platform intimately linked to the semiconductor industry and with Great credibilityYMTC has managed to put avant -garde memory chips capable of rivaling the most advanced foreign solutions. YMTC has published about 20 new patents in which it describes processes that seek to increase efficiency And it has managed to refine its technology of stacking of memory cells in layers known as ‘xtacking’ until reaching a level of performance in its integrated nand type circuits similar to that of the comparable memories of Samsung or SK Hynix. However, this is not all. According to SCMPYMTC has recently published about 20 new patents in which it describes processes that seek to increase efficiency and optimize chips stacking structures. It is evident that the development of the technological capacity of Chinese manufacturers of integrated memory circuits represents a threat to Samsung, SK Hynix and Micron Technology. However, YMTC is not the only Chinese company with the ability to put in trouble the manufacturers of South Korean and American memory chips. Changxin Memory Technologies (CXMT) is one of the Chinese companies specialized in the production of memory chips, and, like other companies in the country led by Xi Jinping, it has chosen to compete in this market so attractive deploying a very aggressive pricing policy. CXMT in particular has increased its production capacity of DRAM chips almost five times during the last four years, which has allowed it to increase its global market share until it reaches a very worthy 9%. This growth has placed this company just behind Micron Technology if we stick to its market share, so it is already the fourth largest memory chips manufacturer on the planet. To curl the curl even more The Chinese government is supporting economically to its manufacturers of this type of semiconductors in response to the sanctions deployed by the US and its allies, so the competitiveness of Chinese companies is upwards.

We knew that smell and memory are closely related. And that unlocks an advantage: detect the Alzheimer’s

by

Alzheimer’s disease may be difficult to detect. The symptoms of this disorder usually become evident only after the progress of this dementia, which is a huge problem. And, in the absence of a definitive cure, our ability to stop the impact of the disease depends largely on early detection. Smell. One of the clues we have when detecting Alzheimer’s in its early stages is through smell. A study conducted by researchers from the University of Chicago analyzed the impact of the disease on our sensory capacity and detected that there is a rapid loss of smell when making us greater could predict with some accuracy The advent of Alzheimer’s disease. Smell of Magdalena. The relationship between memory and smell is very narrow. We know that the evocative capacity of smells It did not go unnoticedbut in recent decades science He has been confirmed This unique connection. The reason for this close relationship can be anatomical. The olfactory bulb is the region of the brain that processes in the first instance the smells and then send the signal to other areas of the brain. This signal crosses key areas of the limbic system, areas linked to emotions and memory. “The olfactory signals reach the limbic system very quickly,” Explain to The Harvard Gazette Venkatesh Murthy, head of the university’s cell and molecular biology department. 515 participants. The study of the University of Chicago had 515 participants, advanced adults, registered in the memory and aging project of the Rush University. These participants were examined annually, exams that test their cognitive abilities to detect signs of dementia. These tests also studied their ability to identify odors, in addition to other health -related parameters. More than memory loss. The team thus found a new link between smell and memory: a rapid loss of olfactory capacity prior to any cognitive loss could predict the arrival of various symptoms associated with Alzheimer’s. These symptoms included a lower volume of gray matter in the areas of the brain linked to smell and memory, cognitive loss and a greater risk of dementia. They also found a relationship between this olfactory loss and the presence of the APOE-E4 gene, a genetic variant considered risk factor in the advent of Alzheimer’s. The details of the study were published In an article In the magazine Alzheimers & Dementia. “This study provides another clue on how a rapid loss of the meaning of smell is a very good indicator of what will end structurally in specific regions of the brain,” ” explained in a press release Jayant M. Pinto, co -author of the study. Get ahead of the disease. Alzheimer’s is an incurable disease for now, but there are different treatments that allow us to delay the development of its symptoms. For that, we must get ahead of the disease as much as we can. Something difficult in a disorder that only shows its consequences once the disease is advanced. “If we could identify their 40, 50 or 60 people with greater risk, we could potentially have enough information to aim them in clinical trials and develop better medications,” also added in a press release Rachel Pacyna, work caoautora. Own initiative. The fact that the change in our smell is rapid and before the arrival of cognitive deterioration opens an important window, putting the patient itself in warning. And it is that most of the ways we have to detect the appearance of dementia is through external evaluations, for example when family members detect memory problems or In language. The loss of smell is something that, in principle, It can be striking to the patient himself and put it on guard or encourage him to seek medical advice. When the smell of the Magdalena stops bringing us memories, perhaps what we are playing is not only the evocation of a memory. In Xataka | We have a new “theory of all” to understand Alzheimer’s.

is leading the creation of a memory standard for the PCs with AI

by

Jensen Huang, the co -founder and general director of NVIDIA, is convinced that in the future most users will have a “supercommer of artificial intelligence (AI) Personal “. At the beginning of last January he led the presentation in the CES of Las Vegas (USA) of Project Digitsa very compact personal computer capable of executing models of up to 200,000 million parametersand therefore bigger than GPT-3. This computer is mainly intended for researchers, developers and students, although a good part of the latter can hardly invest the $ 3,000 (about 2,870 euros) that costs the most economical review of this machine. His heart is a soc GB10 that integrates a GPU with Blackwell architecture and a 20 -core CPU grace with ARM architecture. He works side by side with 128 GB of unified DDR5X type and low consumption type, although NVIDIA available memory standards do not seem to convince him for this scenario of use. Nvidia leads the development of the Socamm memory standard Projects Digits is just the spearhead. Presumably in the future NVIDIA will launch other personal computers even with greater capacities in The field of AIbut it seems that they will not use any of the memory technologies currently available. According to Sedailythe company headed by Jensen Huang has allied with South Korean companies Samsung and Sk Hynix, and also with the American Micron Technology, to develop a new memory standard known as Socamm (System on Chip Advanced Memory Module). Nvidia, Samsung, SK Hynix and Micron for the moment are not having Jedec These three companies are The biggest memory chips manufacturers of the planet, so there is no doubt that they are the best allies to which Nvidia can resort. Especially if the Socamm standard is being devised without Jedec’s participation (Joint Electron Device Engineering Council), which is the global organization that It is responsible for the development of standards used by the semiconductor industry and microelectronics. Apparently it is just what is happening: Nvidia, Samsung, SK Hynix and Micron for the moment are not having Jedec. In any case, what we know right now about Socamm memories, beyond the fact that they will be used in the next batch of personal computers for AI, paints very well. Although this information has not been officially confirmed by any of the companies involved in their development, it seems that the Socamm modules are being designed on the basis of LPCAMM memories (Low-Power Compression Attached Memory Modules). According to Sedaily, the Socamm standard will be very efficient from an energy point of view; It will have more I/O ports than conventional LPCAMM and DRAM memories (up to 694 ports); will allow to easily expand memory initially installed in the equipment for AI; And finally, these modules will have a physical size, which not storage capacity, much more restrained than conventional dram modules. If this standard contributes to the hardware for the most accessible to all, welcome. However, it is still early to trust that it will be so.
