Journal information: Physical Review E (Phys.org) —A pair of physicists has proposed a thought experiment to help reconcile the seeming disparity between the psychological and thermodynamic arrows of time. In their paper published in the journal Physical Review E, Leonard Mlodinow and Todd Brun claim their thought experiment demonstrates that the two seemingly contradictory views of time, must always align. When ordinary people think about time, they see the past as something that has come before and the future as a great unknown yet to come. We can remember the past, because it has happened already, but not the future, because it hasn’t. Physicists, on the other hand see time as able to move either forward or backwards (towards greater entropy), which implies that we should be able to remember events in the future. So, why can’t we?It’s because of the way our memories work the two say, and they’ve created a thought experiment to demonstrate what they mean. Imagine, they write, two chambers connected by an atomic sized tube with a turnstile in it. If there is gas in one of the chambers, individual atoms of it will move through the tube to the other chamber (towards higher entropy) tripping the turnstile as they go, in effect, counting the atoms as they pass by, until both sides have equal numbers of atoms—creating a state of equilibrium. The authors contend that such a system represents a memory—the counter on the turnstile can be used to demonstrate prior states of the system. But, they say, it can also be used to view memories of the future, but only in one special case—where nothing causes a change to the system. If at any point, they note, something causes any of the atoms (from the future) to deviate from reversing the exact course they took to return from where they came from, preventing the restoration of the original configuration, then the system will be move from higher entropy to lower. That would suggest that such a memory system, like our own, can only be used as a one way arrow representing time. And that, the authors note, violates the very definition of a memory. The reason we can’t remember future events is because we have faulty memories.

E 89, 052102 (2014) Published May 2, 2014 dx.doi.org/10.1103/PhysRevE.89.052102ABSTRACTIn this paper we lay out an argument that generically the psychological arrow of time should align with the thermodynamic arrow of time where that arrow is well defined. This argument applies to any physical system that can act as a memory, in the sense of preserving a record of the state of some other system. This result follows from two principles: the robustness of the thermodynamic arrow of time to small perturbations in the state, and the principle that a memory should not have to be fine-tuned to match the state of the system being recorded. This argument applies even if the memory system itself is completely reversible and nondissipative. We make the argument with a paradigmatic system, and then formulate it more broadly for any system that can be considered a memory. We illustrate these principles for a few other example systems and compare our criteria to earlier treatments of this problem.

Michael E. Summers, a professor of Planetary Sciences and Astronomy at the George Mason University in Fairfax, Virginia, and New Horizons co-investigator, is convinced that without any doubt, the mission has already exceeded all expectations.”The information we have received so far from the New Horizons spacecraft has already given us a completely new view of Pluto’s history, how it evolves, and how the surface and atmosphere interact,” Summers told Phys.org. “The images of both Pluto and Charon were astonishing, and gave us some extraordinary surprises. Most importantly, the information has opened up completely new questions about how small bodies in the outer solar system evolve.”Icy dwarf planets such as Pluto are ancient relics that formed over four billion years ago, as scientists estimate. Because they are the bodies out of which the larger outer planets accumulated, they could teach us a lot about planetary formation.One of the most puzzling discoveries is the finding of nitrogen gas on this icy world. New Horizons, during the Pluto fly-by, sent striking images of the dwarf planet’s surface and its atmosphere dominated by nitrogen gas. Pluto’s small mass allows hundreds of tons of atmospheric nitrogen to escape into space each hour. But the question that baffles scientists is where does all this nitrogen come from? This enhanced color image – created from four images from New Horizons’ Long Range Reconnaissance Imager (LORRI) combined with color data from the spacecraft’s Ralph instrument – helps scientists detect differences in the composition and texture of Pluto’s surface. The data hint that Pluto may still be geologically active, a theory that could explain how Pluto’s escaping atmosphere remains flush with nitrogen. Image Credit: NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute Scientists study nitrogen provision for Pluto’s atmosphere Explore further Citation: New Horizons mission exceeds expectations (2015, August 24) retrieved 18 August 2019 from https://phys.org/news/2015-08-horizons-mission.html (Phys.org)—NASA’s New Horizons mission, as the name suggests, is all about broadening our scientific horizons. The spacecraft, visiting the unexplored world of dwarf planet Pluto and its moons, continues to deliver more and more valuable scientific data. The new findings could help astronomers to unlock the solar system’s mysteries hidden at its edge, where the sun glitters as a small bright spot on the sky. “That’s a great question, and one that is currently being discussed in detail by the science team,” Summers said. “The nitrogen atmosphere does extend to very large distances from Pluto, over a thousand kilometers above the surface, which supports the notion that Pluto’s atmosphere is escaping hydro-dynamically from the planet.”According to New Horizons principal investigator Alan Stern, it’s most likely that Pluto is actively resupplying nitrogen from its interior to its surface, possibly indicating the presence of ongoing geysers or cryovolcanism.Besides the nitrogen discovery, the mission team received plenty of valuable scientific data and it’s hard for them to choose the most important finding. © 2015 Phys.org Michael Summers, New Horizons co-investigator at George Mason University in Fairfax, Virginia is seen during a New Horizons science update where new images and the latest science results from the spacecraft’s historic July 14 flight through the Pluto System were discussed, on July 24, 2015 at NASA Headquarters in Washington. Credit: NASA/Joel Kowsky “It’s impossible to pick just one discovery. But near the top would be what appears to be a huge ice glacier, presumably made of nitrogen, methane, and possibly other ices, at Pluto’s equator,” Summers said.He also indicated that the apparently “fresh” nature of the surfaces of both Pluto and Charon that may be implying “young” geological age is also on his list of New Horizons’ top important findings. Another would be the global haze layer seen after the spacecraft’s closest approach and when it was looking back at Pluto. “The backlit atmospheric haze gave Pluto a ‘halo’ appearance,” Summers added.The New Horizons team has so far received only a small percentage of the observational data taken by the spacecraft during its encounter with Pluto. The rest will be downlinked over the coming weeks and months.”You can expect more images at high resolution, in addition to high spectral resolution observations of the surface and atmosphere,” Summers noted.New Horizons, after concluding its Pluto fly-by on July 14, will now focus on studying Kuiper belt objects (KBOs). The potential targets are yet to be chosen. This document is subject to copyright.

The new material, which is a polycrystalline silicon nanowire, breaks two limits: the Casimir limit and the amorphous limit. The Casimir limit is a theory that describes the thermal conductivity of nanostructures, and breaking it means that the thermal conductivity of the new material is lower than the value predicted by Casimir limit theory. The amorphous limit is regarded as the lowest thermal conductivity of a material, since amorphous structures strongly scatter heat carriers. However, due to its unique nanoscale design, the polycrystalline silicon nanowire has a thermal conductivity that is three times lower than that of amorphous silicon materials.The researchers, Yanguang Zhou and Ming Hu at RWTH Aachen University in Germany, have published a paper on the polycrystalline silicon nanowire in a recent issue of Nano Letters.The researchers expect that the new material could be especially useful for thermoelectric applications. By converting heat energy into electricity, thermoelectric materials provide a way to capture some of the waste heat emitted by vehicle tailpipes, power plants, and manufacturing facilities, and then convert the heat into useful energy.In general, good thermoelectric materials are those that simultaneously have high electron conductivity and low thermal conductivity. Together, these two properties lead to a high overall heat-to-electricity conversion efficiency. In the new study, the researchers focused on decreasing the thermal conductivity while maintaining the already high electron conductivity of silicon materials. “In this paper, we report a new structure, polycrystalline nanowire, which can reduce the thermal conductivity to a record low value, only one-third of its amorphous counterpart,” Zhou told Phys.org. “If we keep the electric conductivity and Seebeck coefficient as constants, which can be achieved by doping the material, the efficiency of the polycrystalline nanowire to convert heat to electricity can be enhanced by 277 times with respect to its bulk counterpart.” Engineer creates new technique for testing nanomaterials (Phys.org)—Researchers have theoretically demonstrated the lowest rate of heat transfer, or thermal conductivity, in any silicon-based material developed so far. The key to the new silicon nanowire’s low thermal conductivity is its polycrystalline form, which consists of many crystal structures of varying shapes and sizes in random orientations. Based on the average grain size (about 3 nm) in the polycrystalline silicon nanowires, the Casimir limit predicts that the thermal conductivity cannot be below approximately 3 W/mK. But the researchers’ simulations show that the polycrystalline silicon nanowires have a thermal conductivity of just 0.7 W/mK. For comparison, this value is 269 times lower than that of bulk silicon, 77 times lower than that of pristine silicon nanowires, and three times lower than that of amorphous silicon nanowires.The researchers explain that an important feature of the polycrystalline structure is that the grain boundaries between crystals are discontinuous. As a result, the grain boundaries block and scatter the heat-transporting phonons, so that the phonons cannot move very far (only about 1 nm) through the material compared to how far they can move in other silicon materials (up to 1 µm), in which the grain boundaries form a continuous network. The results here raise the question of what the lowest possible thermal conductivity may be for silicon nanowires of any form. In general, there are two kinds of vibrations that contribute to thermal conductivity: propagons and diffusons. The researchers expect that it should be possible to completely eliminate the contribution of propagons by incorporating disorder in the form of nanotwinned structures into the polycrystalline silicon nanowires to minimize their transport. Diffusons, on the other hand, are caused by the inherent structural disorder of a material, so they cannot be reduced in this way. Nevertheless, by eliminating the contribution of propagons, the researchers expect that the thermal conductivity of the polycrystalline silicon nanowires can be further reduced by 20%. The researchers plan to pursue this goal in future work. © 2016 Phys.org Explore further More information: Yanguang Zhou and Ming Hu. “Record Low Thermal Conductivity of Polycrystalline Si Nanowire: Breaking the Casimir Limit by Severe Suppression of Propagons.” Nano Letters.

Kolkata: The use of artificial colour in food products is soon coming to an end as the state Agriculture department has taken steps to ensure massive plantation of Bixa trees in the state for its seeds.Yellow-orange dye extracted from its seed is a safe colouring agent for food. The state Agriculture department would also discuss the issue with the state Science and Technology department for using updated technology to process the seeds and extract natural dye from it. Also Read – Rain batters Kolkata, cripples normal lifeTaking the unique move, the state Agriculture department would initially go for plantation of the same in all the farms and help increase the yield of Bixa seeds.During a recent visit to Fulia Agriculture Training Centre in Nadia, the state Agriculture minister Asish Banerjee noticed two Bixa trees, which is commonly known as lipstick tree. After getting to knowing the usefulness of the seeds, the minister gave direction to take necessary steps to increase the yield of the same. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedBanerjee said: “Direction has been given to increase plantation of Lipstick Trees. At the same time, there will be discussions with the state Science and Technology department in connection with the updated process of extraction of colour from its seeds.”Following the direction of the state Agriculture minister, senior scientists at Fulia Agriculture Training Centre initiated their work to increase its production.With the immense success of the scientists, around 2 kg of seeds have been kept ready and using the same, lipstick cultivation is possible on a plot 70-bigha. Initially, the state Agriculture department will carry out cultivation of Lipstick trees in all its farms across different parts of the state. The state Agriculture department has also taken steps so that no place in farms is left vacant. Once the yield of lipstick seeds goes up, the natural yellow-orange Bixa dye would become easily available in the state.With proper promotion of the Bixa seed dye, it will become popular among food product manufacturers and the tendency of using artificial colour will go down.Often the use of artificial colour in food products turns out to be an issue in certain parts of the state. Steps need to be taken to check such practice. But with this move, there would be a permanent solution to the menace.It may be mentioned that Bixa tree has become commonly known as the Lipstick tree as its seeds were used to make lipstick and body paint in certain parts of America.
Winter is here, which means your baby needs extra care and attention. Baby skin requires a lot more nourishment during winter, as the temperature drop tends to make the skin dry. Winter also brings with it various skin problems for babies, as their skin is more delicate when compared to adults. Experts shares a few tips to nourish your baby’s skin: Oil massages: Nourishing the skin with regular oil massages before bath significantly reduces skin dryness and improve skin softness. Choose an oil infused with olive and winter cherry (Ashvagandha); this helps improve the skin tone and soothes the baby’s skin. Also Read – Add new books to your shelfBaby bath: It is advisable to bathe the baby once in two days with lukewarm water. If the water is too hot, it can hurt the top, protective layer of the skin. Bathing a baby for long can also strip the moisture off the skin. Hence, reducing bath time during winters is recommended. Using cleansers: Using a gentle cleanser infused with the goodness of aloe vera, almond oil and milk, can help prevent post-bath dryness in the baby’s skin and soothe excessively dry skin. Also Read – Over 2 hours screen time daily will make your kids impulsiveMoisturising: Using these post-bath enhances the skin’s wellness by locking in the moisture, which keeps the skin hydrated. Opt for a baby lotion enriched with natural oils and licorice (Yashtimadhu) to keep the skin supple and nourished. Creams: Using a baby cream with the goodness of country mallow (Bala) and licorice (Yashtimadhu) will condition and protect your baby’s skin, especially chapped cheeks, “crawler’s knee”, tender nose, and rubbed elbows. Wrapping the baby: Avoid wrapping your baby in a woollen sweater or blanket directly, as the rough fibre will scratch baby’s sensitive skin, leading to a rash. It’s best to use breathable winter clothing to keep the baby warm. Almond and olive oils, aloe vera, winter cherry, licorice, honey, and milk are a few handy herbs/ingredients which are known to lock in moisture and will help provide the best skin care for your baby during winters.

Opinions expressed by Entrepreneur contributors are their own. 3 min read Free Workshop | August 28: Get Better Engagement and Build Trust With Customers Now When Joshua Marshal wanted to start a new business on eBay, it was like the proverbial light had gone on over his head. Hundreds of lights, in fact, and mostly from his family’s retail lighting store in New York City.Lighting has been the Marshal family business for four generations, but Joshua, 22, was the first to introduce the company to e-commerce. Marshal had already gotten his feet wet on eBay selling electronics and clothing. When he wanted to change product offerings, the family business seemed like a no-brainer.”I realized I could get my hands on unlimited lighting,” says Marshal (eBay User ID: wegotlites), who started in 2004 with excess stock from the family store. Now running his own business, WeGotLites.com, Marshal has broadened the supply chain for his eBay Store with overstock from other lighting stores, going-out-of-business sales and orders placed directly with manufacturers. “In the beginning, I had to beg suppliers to sell on my website,” he says. “Now I’m to the point where I have owners of companies I don’t even know calling me.”Marshal’s successful sales record on eBay–seven-figure sales in 2005–has raised him to an enviable negotiating position with suppliers. Because his merchandise moves so quickly online, he can sometimes get 20 percent off the wholesale list price from lighting manufacturers.Like Marshal, many retailers first come to eBay to turn overstock, returned items and outdated merchandise into successful online sales. Most of these newcomers stick to the familiar range of products already being sold in their brick-and-mortar stores. For other businesses, though, eBay is a low-risk, low-cost way to test the appeal of new products before they go on the shelf, or to connect with new suppliers who offer similar products at different price points and of different quality from in-store inventory. “In the past, if we heard of a deal, we would pass on it if the product wasn’t something we would normally put in our stores,” says Scott Touchette, director of auction sales at Bargain Sports (eBay User ID: bargain–sports). “Now, we buy large lots of liquidated inventory that we only sell on eBay.”Online selling means more than trimming inventory. The benefits can ripple through your business by bringing in new regular customers from across the country, and even from around the world, who would otherwise never make it to your store. That growing sales track record can then attract more potential supply partners, further expanding your business.Of course, some items work better than others for selling online. Touchette says his company avoids listing items that are too heavy and expensive to ship. Even when products don’t sell for much of a profit, he says, “It’s still a tool that gets traffic to our eBay Store.”And that traffic can arrive anytime, day or night–a fact that underscores one of the more powerful advantages of online sales. “With retail, if your key is not in the door,” Marshal says, “you’re not making any money.”

Known officially as Patent Assertion Entities, they don’t actually create new products, but instead make money by amassing a collection of patents and suing accused infringers.Big corporations typically have the resources to fight them off, which explains why most patent infringement lawsuits are filed against small to medium-sized companies. When it comes down to choosing between a lengthy, expensive complicated legal battle with a patent troll and paying a licensing fee, many startups don’t have the luxury of selecting the former option. Patent trolls cost small companies about $11 billion in 2011, and despite attempts by lawmakers to reform our broken patent system, the number of lawsuits filed by patent trolls has dramatically increased in recent years.Related: Looks Like Big Tech Is Winning the Battle With Patent TrollsBut now comes news that has the potential to change the nature of the patent trolling business. RPX — a company that strategically buys patent licenses to protect its clients from infringement lawsuits – is now offering its services to small and medium-sized businesses.In other words startups, no matter how small, can now buy protection against patent trolls. Premiums for companies with less than $20 million in revenue range from $7,500 to $10,000; If a covered company gets slapped with a lawsuit from a patent troll, RPX will shoulder legal or settlement costs up to the company’s limit (which starts at $1 million but can go up to $10 million), although that’s only after it pays a retention, which RPX says starts at $25,000. “This is a game changer because it levels the playing field for small companies by transforming a previously uninsurable threat into a manageable business risk,” John Amster, chief executive and co-founder of RPX, said in a press release. “This insurance policy for small companies now enables RPX to offer insurance for any sized company, from the smallest start-up to multi-billion dollar enterprises.”Up until this point, RPX had only offered its “patent risk solutions” to large companies (current clients include Google and Apple).Related: Yes, Patent Trolls Are Hurting Your BusinessWhile RPX’s services for small businesses aren’t negligible – it’s unfortunate that small enterprises need to worry about this in the first place — the model is intriguing: Essentially, RPX is offering its expertise in negotiating and litigating patent cases to startups. Under RPX’s protection, a small business can’t be easily bullied into paying a licensing fee just to avoid a legal mess.Jamie Balboni, a principal and intellectual-property expert at insurance brokerage Williams Gallagher Associates, told The Wall Street Journal that small tech startups are particularly vulnerable to patent troll lawsuits.However, in RPX she sees a ray of hope (for the tech sector, at least): If the company is successful, she told the outlet, patent trolls “will just move on to another industry.”Related: Entrepreneurs Want Patent Trolls Gone, But Current Legislation Is Sloppy Growing a business sometimes requires thinking outside the box.

August 14, 2017 Free Workshop | August 28: Get Better Engagement and Build Trust With Customers Now 5 min read Enroll Now for Free This year will be known as the year enterprises became artificially intelligent. Research by Gartner suggests that interest in new big data investments has peaked. The question has changed from “how do we get data?” to “what do we do with it?” Forrester found that enterprises plan on increasing investment in artificial intelligence (AI) by 300 percent in 2017.One area of major AI investments will be sales. Customer analytics are one of the largest data sources for enterprises, and Salesforce already made a big splash earlier this month by releasing Einstein, their AI assistant designed to help sales teams uncover insights that will help close deals and identify upsell opportunities.But how exactly will sales be upended by AI? I see three main areas:1. Process optimization.According to CSO Insights, 43 percent of enterprise sales reps miss quota. The main reason? Lack of efficient, organized sales processes.AI will make huge inroads in regards to optimizing the sales process, beginning with the onboarding of new reps, which currently takes upwards of six to 10 months to reach full productivity.Based on observing the actions of high-performing reps, AI will provide a blueprint to new reps, offering guidance in terms of how often reach out to a prospect and what collateral to send them to be most effective in closing deals. This “autocoach” functionality will mitigate the time in which new reps operate at a loss because they are acting in a statistically similar way as high-performing reps.Related: 3 Traits High Performing Sales Reps Have That Average Sales Reps Don’tContent and meeting preparation processes are also primed for AI, particularly through natural language processing (NLP). For example, client-facing collateral in regulated industries, like financial services, is often required to include correct disclosures, a manual process usually delegated to reps. NLP can automate this process through keyword scanning, and as sales compliance remains a hot button issue in financial services, expect to see AI play a major role.NLP will also improve how sales reps prepare for meetings by bringing context front-and-center. By leveraging data accrued from past meetings across the sales organizations, sales reps will know what pieces of content — and even what order of slides — will work best for the particular combination of buyers in the room during a presentation.Which brings me to my next point …2. Personalization.Eighty percent of B2B sales organizations find personalized interactions to be most effective with buyers. Unfortunately, Forrester has found that 78 percent of buyers say salespeople come to meetings with irrelevant or incorrect materials.AI opens up a new world of personalization in sales conversations. One important instance will be in lead scoring. Right now, lead scoring essentially involves qualifying leads by fairly large, non-specific buckets based on previous interactions and subjective human input. With AI processing data from the entire marketing, sales and UX technology stacks, lead scoring will become exponentially more granular, where sales reps are handed personalized blueprints on how to approach each lead as an individual.Related: Why AI Won’t Replace (Great) SalespeopleFrom there, AI will also usher in dramatic changes to the content used by sales reps. Integrating data coming from the Internet of Things opens up particularly intriguing cases. Today this data primarily assists product monitoring, but it’s not hard to see a situation in which, say, Boeing, through the digital monitoring of their own commercial machine parts, reaches out to American Airlines with a personalized product brochure — automatically personalized with the right logos and pertinent case studies for the individual buyer — on new turbines the moment there are indications that it may be time for a new one within their fleet.3. The elimination of mundane sales tasks.Popular calendar and scheduling tools are, frankly, a giant pain for everyone involved. Our sales team of 60 schedules about 3,600 meetings per month. If each meeting takes 10 minutes of sending calendar invites back and forth and including new attendees, the result is 600 hours per month wasted scheduling meetings. We’re already seeing a crop of new tools that leverage AI to help with scheduling meetings. X.ai, for example, automates the email back and forth for the sales rep.Another manually intensive area of sales is note taking. Required for proper follow-up, note taking can also distract the rep from giving his or her full attention to the buyer. Clarke.ai is claiming to solve this problem via NLP. By dialing into the service before a call, Clarke.ai will record the context of the meeting and provide it back to the seller automatically.Bringing it all togetherWhile the tactical changes promised by AI will no doubt change the day-to-day of sales reps, its true benefit lies in the feedback loop. Big data investments have allowed data to be collected from all areas of the customer experience, from first touch to the monitoring of products they end up using. AI will be able to pinpoint and predict areas of strength and weaknesses in the experience of each new lead that comes through, improving the entire sales and marketing process intelligently and automatically.Related: Top 10 Tools for Maximizing Business-to-Business SalesThe main problem with AI and sales is how companies position these new technologies to the sales floor. AI can induce anxiety and anger when introduced improperly. It should be made clear that, when it comes to maximizing their time spent selling, AI promises to be a boon for reps, resulting in higher compensation, meaningful relationships with buyers and bottom-line company success. According to SiriusDecisions, these also happen to be the top reasons why sales reps stay with a company, resulting in long-term and enjoyable work in which the rep can find meaning and success. This hands-on workshop will give you the tools to authentically connect with an increasingly skeptical online audience. Opinions expressed by Entrepreneur contributors are their own.
Author Bio Credit: Michael Schwartz/TwitterThere are conflicting arguments as to whether hyper-threading should be disabled on all computers affected by the flaw, which includes those with an Intel chip from 2011 or later. (Intel says the flaw does not affect some 8th Gen and 9th Gen CPUs; the researchers who discovered ZombieLoad and its three related vulnerabilities disagree.)Intel specifically said that it does not recommend disabling hyper-threading because of the various factors affecting the security of individual users. Google, on the other hand, is disabling hyper-threading by default on Chrome OS 74, which rolled out earlier this month. Microsoft, like Apple, also recommended disabling the performance feature for reassurance, though it left it to users’ discretion. Apple specifies that users with “computers at heightened risk or who run untrusted software on their Mac” (“untrusted: may mean applications unavailable in the Mac App Store) can optionally disable hyper-threading. While the company didn’t specify who that involves, we suspect government officials, executives or anyone with sensitive data that hackers might want to get their hands on would fall under the category. If you’re in that group or want to be extra cautious, follow these steps to disable hyper-threading on your Mac. Note, this method is only available for computers running macOS Mojave, High Sierra and Sierra. How to disable hyper-threading on your Mac1. Turn on and restart your Mac then immediately press the Command+R or another macOS Recovery key on your keyboard. 2. Choose Terminal from the Utilities menu from the menu bar. 3. Type the following command into the Terminal prompt: nvram boot-args=”cwae=2″4. Press return then type: nvram SMTDisable=%015. From the Apple menu, press Restart. Phillip Tracy, If you haven’t read the news yet, another set of devastating flaws was discovered on Intel CPUs that allows hackers to steal personal data, including web browsing history, passwords and encryption keys.Frequently referred to as ZombieLoad (or Microarchitectural Data Sampling by Intel), the security exploit is actually four distinct attacks, all with the same goal of nabbing your sensitive data.

However, the software updates coming to macOS, Windows and Chrome OS may not be enough for some users. After releasing security updates in macOS Mojave 10.14.5, Apple published a support page explaining that the only way to fully mitigate ZombieLoad is to disable CPU hyper-threading. Doing so, however, could decrease your system’s performance by up to 40%, according to Apple’s own internal testing. MORE: ZombieLoad Attacks May Affect All Intel CPUs Since 2011: What to Do NowHyper-threading is a technique used by Intel that splits a physical core into two virtual cores, or threads. This results in significant performance gains, particularly when running CPU-intensive apps or programs. When turned off, your computer must rely on only its physical cores. by Taboolaby TaboolaSponsored LinksSponsored LinksPromoted LinksPromoted LinksYou May LikeVikings: Free Online GameIf you’re over 40 – this game is a must!Vikings: Free Online GameUndoKelley Blue BookClick Here To See Which Lexus Car Model Fits Your BudgetKelley Blue BookUndoMayo ClinicSlide show: 5 smart exercise choices for psoriatic arthritisMayo ClinicUndoVerizon WirelessThis new phone will blow your mind.Verizon WirelessUndoTODAYCeline Dion Reassures People After Major Weight Loss Raises ConcernsTODAYUndoMy Food and FamilyMake 20 Minute Grilled Tacos al Pastor This SundayMy Food and FamilyUndoAdvertisement Phillip Tracy is a senior writer at Tom’s Guide and Laptop Mag, where he reviews laptops and covers the latest industry news.

TrayStatus: Caps Lock and other information on Windows taskbar by Martin Brinkmann on March 30, 2017 in Software – 7 commentsTrayStatus is a free and commercial software for Windows that highlights the Caps Lock status, and other information, on the Windows taskbar.The Caps Lock and Num Lock keys on a computer keyboard can cause some troubling experiences when you they toggled without you realizing it.Caps Lock for instance may result in passwords not being accepted because you type different characters than you intend to. Num Lock on the other hand locks and unlocks the numpad, and if you use it regularly, you may have tapped on five or more keys already before you realize that none was sent to the computer.TrayStatusTrayStatus is available as a free and professional version. The free version of the program may be used for personal use only, and lacks a handful of options of the professional versions.The core functionality, the display and monitoring of certain keys on the computer keyboard, is available however.TrayStatus is available as a portable version or installer. Both offer the same functionality, but you may need to make more adjustments to the portable version (e.g. autostart with Windows).First thing you may want to do when you run the program for the first time is to open the settings. These should launch automatically, but if they don’t, right-click on one of the program’s icons in the system tray area, and select settings to open them.The status indicators page lists the available indicators that TrayStatus may display as individual icons on the taskbar. They are:Caps Lock Status.Num Lock Status.Scroll Lock Status.Kana, ALT, CTRL, SHIFT, WIN status.Hard Drive activity.CPU usage (PRO).Memory usage (PRO).Audio Playback Status (PRO).The program displays a separate icon for each indicator that you enable. Yes, this can lead to more than ten icons being added to the Windows system tray area if you enable them all.Please note that the icons may be hidden behind the system tray menu on newer versions of Windows by default. You need to change the visibility of the icons first, before they are visible all the time.On Windows 10 for instance, you’d have to right-click on the arrow icon in the system tray area, select Settings, and on the Taskbar settings page that opens “select which icons appear on the taskbar”.You find each icon that you have activated in the program settings there individually. Depending on how you use your system, you may either want to restrict the display of indicators to Caps Lock and Num Lock, or enable additional indicators if you find them useful.One interesting feature of each icon is that you can toggle the status with a double-click. The icons do change their appearance depending on their status. It is usually the case that a white background indicates that the key is active, and a black that it is not active.Tray Status offers a couple of other settings that you may find interesting. You may enable autostart with the operating system under General for instance. There you find options to play a sound whenever the key status changes, and may use different sounds for on and off status changes.The status indicators page of the settings allows you to change the theme of the icons, for instance to dark icons, and to separate hard drives so that each is shown with its own icon.The program used about 25 Megabytes of RAM on a 64-bit Windows 10 system in the background with three indicators enabled. This is more than other programs such as NumCapsScroll Indicator or Keyboard Leds require. TrayStatus is more powerful than those programs on the other hand, and it is still updated regularly while the mentioned programs are not.Closing WordsTrayStatus is a powerful key indicator for Windows that may also display the hard drive, memory and CPU status in the system tray area of the operating system.Summary12345 Author Rating5 based on 4 votes Software Name TrayStatusOperating System WindowsSoftware Category ProductivityLanding Page https://www.traystatus.com/ Advertisement
How to build from source code in GNU/Linux by Mike Turcotte-McCusker on May 24, 2017 in Linux – Last Update: May 23, 2017 – 10 commentsMost repositories for many GNU/Linux distributions have mass amounts of software and packages available within them; it’s becoming more and more rare you are required to build anything from source (unless you use Gentoo), however, many users are left unaware of how to do so if the need ever arises.This tutorial will show you from beginning to end, how it’s done. I use Arch Linux, so little quirks may arise that are slightly different from distributions like Ubuntu, but the process is nearly identical, except when fulfilling dependencies comes into play.Note: This tutorial will be done almost entirely within the command line, so be prepared to get your hands a little dirty and have a terminal window open!We are going to build Pidgin, from source. Pidgin is a popular multi-protocol chat client, used to connect to multiple different chats at once, such as Skype and Facebook Messenger (There is an article here on Ghacks, showing how to connect to those very two)Pidgin is available in most distribution repositories, but I thought we would build it, since it’s simple, easily done, and won’t get super complicated for your first time building.Step 1: Download the sourceFirst thing we need to do, is get our sourcefiles! You can grab them from here.Once those are downloaded, pop open your terminal and navigate to your Downloads folder (or wherever you downloaded that tarball to)cd /DownloadsNext, we need to unpackage the archive, we do this via the ‘tar’ commandtar -xf pidgin-2.12.0.tar.bz2Note: the -x tells tar to extract the filethe f tells tar to read the archive content from a file, like our pidgin-2.12.0.tar.bz2next, we cd into the directorycd pidgin-2.12.0/Next, we need to configure the source code for our machine, and ensure that we have all the necessary dependencies required to build the source.Typically this is done simply by typing ./configure, however, I know that pidgin is going to error if you do that because most distributions do not have the necessary packages to compile two parts of Pidgin: required for TCL support (an older programming language rarely used anymore), as well as packages needed to support ‘meanwhile’, which is needed for using Pidgin with “Sametime,” an IBM instant messaging service/product.So, unless you specifically need support for TCL or Sametime, we are going to tell our system to disable building those packages into Pidgin, therefore bypassing our need to fulfill those requirements to configure the application!./configure –disable-meanwhile –disable-tclif everything goes well (as it did on my very minimal Arch Linux install, so users of more robust distributions also ‘shouldn’t’ run into issues), you’ll get a bunch of scrolling text on the screen, eventually telling you:configure complete, now type ‘make’…Which is exactly what we do nextmakeYou’re going to see a whole bunch of text absolutely flood your terminal at this point. You on the other hand are going to go get a coffee, walk the dog, or post that image on social media you’ve been wanting to post and kept putting off; this is going to take a few minutes (it took around 5 minutes or so on my laptop)Once that’s finally finished, the last step is to install Pidgin!sudo make installWhen the wall of text is finished, so are you!Note: I had to log out and back in, before Pidgin showed up in my applications menu. If you don’t see it, try that.To sum it up:Download the source file and extract it.Run ./configureRun makeRun sudo make installFinal WordsThat’s it! That is the basics of compiling applications from source. Some applications are done a little differently, but that is another topic for another day; you’ll find this process is the same for many, many programs. So, enjoy!SummaryArticle NameHow to build from source code in GNU/LinuxDescriptionMike explains how to build a software program from source on GNU/Linux devices. He uses Pidgin as an example, and walks you through all steps.Author Mike TurcottePublisher Ghacks Technology NewsLogo Advertisement
