The security hole exists for more than 3 years, but Intel has not been able to fix it. Photo: CIO Indeed, 3 years have passed, and there is still no end to the vulnerability. Meanwhile, experts from the University of Virginia and the University of California, San Diego, have discovered a new attack method that bypasses all current Specter protections built into the chip. This attack method has the potential to put almost any system – desktops, laptops, cloud servers and smartphones – once again at risk. Revealing Specter ushered in a wave of more powerful attacks, allowing malicious code to directly read passwords, encryption keys, and other valuable information from the computer’s kernel memory. Although chip manufacturers such as Intel, ARM and AMD already know this and combine defenses to reduce the threat from vulnerabilities, the methods have not yielded the desired effect. A Specter attack is capable of tricking the processor into executing instructions along a wrong path, the researchers say. Even though the processor recovers and completes its task correctly, hackers can still access confidential data while the processor goes in the wrong direction. The new attack method exploits what is called a micro-operator buffer (called micro-ops), an on-chip component that breaks machine instructions into simpler instructions and speeds up computation, like a secondary channel to reveal confidential information. Micro-op cache is built into Intel processors, manufactured since 2011. According to researchers at the University of Virginia, Intel’s defense proposal against Specter (called LFENCE) is to place sensitive code in a waiting area until security checks are done and only then the code Only sensitive is allowed to execute. However, research has shown how attackers can steal information through micro-op caching and use it as a secret channel. Although exploiting the Specter vulnerability is very difficult, the researchers say that with computers with a lot of sensitive data, hackers do not mind the difficulty. To protect the system from the new attack, the researchers propose to clear the micro-ops cache. This is a technical solution that comes at the expense of performance benefits. According to the researchers, micro-op caching has some dangerous effects. First, it ignores all caching reduction techniques such as side channels. Second, attacks in this zone go undetected like an existing attack or malware. Third, because the micro-op cache is at the front of the path, prior to execution, Intel’s Specter protections or recommendations to limit cache updates are still compromised. public.

That is “Dry-aged” beef, because there is no equivalent name in Vietnamese, it is temporarily called “aged” beef (aged can be translated as “aged” or “aged”). But that name does not say all the meaning of this special dish. Dry-aged beef is a specialty of many famous Steakhouse in America. (Photo: Internet) The simplest way to describe this beef is that people will let the meat dry naturally for so long that a moldy layer begins to appear on the meat. At this time, the chef will use a knife to cut off the mold on the outside, revealing the taste that is considered “excellent” inside. Many foreign diners are also willing to pay a higher price for these “moldy” beef pieces. Don’t be scared by looking at this moldy beef specialty, because people will cut off the mold first and only use the inner meat for cooking. (Photo: Internet) Dry-aged beef can be processed like normal beef, by baking, frying and pan-frying with many popular ingredients such as butter, dill, salt, and pepper … This dish after processing. The appearance does not look very different from ordinary beef, but the taste – according to the experience – is extremely delicious. Principle of deliciousness of Dry-aged beef The taste of Dry-aged beef is like “a bomb”, because when eaten it will cause a flavor explosion in your mouth cavity. The principle behind the deliciousness of Dry-aged beef is similar to why people like to eat aged cheddar, and may not even hesitate to taste green mold cheeses. Food created by aging, if properly cooked, has a great taste. Once processed, the moldy beef is a great treat. (Photo: Internet) Jack Kawa, owner of Omaha restaurant with a seniority of steak sales since 1922, said that the reason for the deliciousness of Dry-aged beef is that the muscle fibers will be “broken”, making the meat texture become softer. . Inside the moldy steak are soft, “explosive” flavors of meat. (Photo: Internet) However, you cannot arbitrarily leave a raw steak out and expect it to taste good. To “aged” beef, or “aged” beef properly is also an art. Not simply for “mold”, aged (or “aged”) to crawl requires technology Most Dry-aged beef steaks are more expensive than regular beef and there are good reasons for that. Page Eater says a 25 to 30 pound serving of fresh meat can “shrink” enough for only five to seven steaks. Also, this should take at least a month. So theoretically, those who want to eat Dry-aged beef will have to pay extra for the “losses” in processing with effort and time. There are two ways to “age” a steak, according to Thrillist, “dry” and “wet”. (Photo: Internet Drying a piece of meat means letting it dry naturally in an environment where the temperature and humidity are precisely regulated. The wet method must be stored in vacuum packaging. If done right, the end result will be a tender, hydrated meat with a hidden “bursting” flavor. Many people even hang meat in an enclosed room filled with Himalayan salt, because the salt concentration in the room helps distribute the appropriate humidity for the Dry-aged beef environment.

One of the steps to graft the branches to renovate citrus varieties. Photo: H.Tien. Steps taken before transplanting – On the garden of sour grapefruit varieties or low quality indigenous grapefruit varieties (real grapefruit): Choose plants that are 3-7 years old, grow well, be free of pests and diseases, especially have no stem borers, no germs. leaf rot yellow leaf disease, greening leaf yellowing (Greening) and Tristera’s disease. Then, cut down the entire canopy to the stem or branch with a diameter of ≥ 2cm, leaving only the ends for eye grafting in the position of the stem with the color of the cake, the same size as the top of the chopsticks. The number of branches left for grafting should be arranged evenly 0.5 m on the tree canopy as a mesh. Grafting season can be carried out all year round. It is best to graft in 2-3 months and 9-10 months. Note, stop watering and fertilizing on real plants 15-17 days before grafting; do not extract and graft trees into the rain. – On the mother Ruby grapefruit tree, choose a tree that grows balanced and free from pests and diseases as above. It is advisable to choose mother plants grown in a net house to prevent insects, to avoid completely dangerous diseases such as Greening and Tristera. Then, select branches under 1 year old, have rounded stems and are tilted from horizontal canopy upwards, then remove all leaves, leaf stalks attached and remove the tip at the position of the stem color of the cake. Continue to cut the branches to divide the seedling into branches containing 4-5 leaf axils, 7-10 cm long and have a flat color. Technique of grafting the branches (also called grafting, grafting wedge) – At the base of the seedling segment, use a specialized knife to cut 2 opposite beveled slices, 2-2.5 cm long to remove 2 stem parts at the base of the seedling and open a wedge-shaped composite end. At the predetermined graft head on the phylogenetic tree, split a line 2.5 cm deep at 1/3 of the tip diameter to open a grafting mouth, insert the wedge-shaped graft head into the grafted mouth that just opened above. Ruby grapefruit has been successfully grown in our country. Photo: TL. Then, stretching and twisting the nylon strip, twisting the rope, then wrap 5-6 rounds tightly around the graft. Finally, pull the grafted plastic strip flat, completely covering the seedlings and grafting spots, so that rain cannot penetrate the grafting marks and keep the seedlings from dehydrating. After about 10-15 days (depending on the season), the grafted eye will sprout. Must eradicate in time the sour grapefruit sprouts growing outside the grafted eye. Note choosing self-destructing polypropylene tape. – In addition to improving the seed by grafting wedge into the branches mentioned above, it is also possible to graft wedge into the cross section of the branches of much larger size, or graft windows, small wooden eyes along the trunks. tree, trunk. However, these grafting methods have certain limitations, compared to the method we introduced in the previous section, such as, small eye grafting with wood, only taking the seed eyes open, the tree will grow long. , time for exploiting business results is slower … Take care of real plants after grafting Spraying to draw amulets when the eyes are like sprouting is 0.5-1.0 cm long. Except for red spiders, soft aphids, leaf hoppers and plant diseases, during the period when eyes are like spreading branches and canopy. Fertilizer for 1 root: 0.2-0.3 kg NPK 13-13-13 + TE, fertilize periodically once a month. Foliar fertilizer sprayed evenly 7 days / times. Decomposed chicken manure 20-30 kg + 2-3 kg of microbiological organic fertilizer, fertilizing when the grafted eye has reached about 15 cm long branches. After 1-2 years grafting and improving, Ruby grapefruit trees have been exploited for business. From this stage on, the steps to take care and control pests and diseases are similar to other current pomelo seedlings. Ruby grapefruit is one of the elite citrus varieties of Thailand, which has been imported into our country. The variety has the advantages of strong growth and development, beautiful fruit shape, good resistance to pests and diseases, red fruit, thick and thick pods, fragrant sweetness, no seeds … Grapefruit is equivalent to or slightly better than that of our country’s green skin grapefruit. , depending on farming techniques and ecological conditions. Ruby grapefruit tree is easy to distinguish from other grapefruit varieties thanks to the small leaves and branches, smooth hair.

A sprain is a term used to describe the damage to the ligaments that hold a joint due to an injury. During a sprain, one or more ligaments stretch or tear. The most common are ankle sprains caused by trauma to the external ligament and ankle sprain. During physical activity, the ankle may turn inward as a result of sudden, sudden movements. This causes one or more ligaments around the ankle to stretch or tear. Swelling or bruising in the ankle is the result of an injury that tears the ligament of the ankle.

An ankle sprain is a common injury that occurs with vigorous exercise or falls. The ankle sprain is usually caused by the foot twisting or turning inward, forcing the ankle joint to deviate from its normal position. This condition occurs more often when wearing high heels regularly.

While a sprain is usually mild and not a serious medical condition, it can cause discomfort and discomfort due to pain and limited daily activities.

After a sprain, apply cold immediately

Factors that increase the risk of sprains

Poor physical condition: Poor physical condition causes muscles to weaken and is more likely to suffer injuries.

Fatigue: Fatty muscles are less likely to provide good support to joints. You’re also more likely to succumb to the stresses that can strain joints or strain muscles;

Incorrect start-up: Warm the body properly by relaxing the muscles and increasing joint mobility before sports, helping to reduce muscle tension and less risk of injury and muscle tear. ;

Environmental conditions: Slippery or uneven surfaces may make them more susceptible to injury;

Poor support: Shoes that are inadequate or of poor quality, or inadequate sports equipment can contribute to muscle strain or sprains.

Note the taboos

When a sprain occurs, there will be bleeding where the ligament is broken, depending on the severity, the bleeding will be more or less. Bleeding causes swelling of the sprained joint. Bruises around a joint are caused by blood clotting, sprains heat up, and compress pain. After the injury, inflammation occurs immediately on the sprained area.

The trick many people have passed by word of mouth to do that is hot compresses, hot oils … on the sprains, this is the wrong thing. If after a sprain, we use a hot compress, squeeze oil, squeeze alcohol or medicine to make the bleeding worse. The victim, after seeing the pain relief from the hot compress, now suffers from more pain due to more bleeding and a worse inflammatory response. The swollen joint becomes even more swollen due to poor blood circulation. As a result, sometimes an ankle sprain can take nearly half a year to return to normal. Absolutely do not massage anything even genuine bear bile. Folk methods such as applying leaves, squeezing salt … should be avoided.

The correct solution is that after a sprain, whether heavy or mild, cold compresses should be applied immediately, although this time it makes the patient a bit uncomfortable. Avoid exposing ice directly to the skin that could cause cold burns. Apply the pressure bandage using the elastic bandage gently, neither too much pressure nor too loose. Raise your limbs by lying with your feet resting on a pillow about 10cm, and if sitting, your feet are at hip height (pelvis). The goal is not to let the blood rush to the leg, causing the swelling of the leg. Then should see a doctor for further counseling on management, to help the sprain quickly heal.

Note: To limit sprains, women (especially women over 40 years old) should not wear high heels more than 7cm, which will fit, making the feet uncomfortably stretched, prone to sprains, and flipping ankles. heal, because as the older, the musculoskeletal condition is no longer as sure as when the child was.
