(PhysOrg.com) — A prototype of a new type of photovoltaic (PV) cell that generates electricity from visible, infrared and ultraviolet light has been demonstrated by a group of Japanese scientists. It could lead to the development of a highly-efficient PV cell in the future, without needing multijunction cells. IMEC unveils promising mechanically-stacked GaAs/Ge multijunction solar cell The research was led by Associate Professor Saki Sonoda of the Kyoto Institute of Technology. The prototype cell has a high open voltage (Voc) at around two volts, but a low energy conversion efficiency. Sonada and the team hope the conversion rates can be improved. Photovoltaic materials convert light to electricity at the atomic level by absorbing photons of light and releasing electrons that can be captured to produce an electric current. Most PV cells are multijunction devices, with single junction cells stacked in descending order of band gap. The cell at the top captures high-energy photons, while those at the bottom with lower band gaps capture the lower energy photons. The new cell is able to capture photons with a wide range of energies in a single junction cell.The team made the 10 mm square PV cell by adding elements such as manganese (Mn) or cobalt (Co) to the transparent semiconductor material gallium nitride (GaN). When the element is added, the absorption coefficient of GaN is higher, allowing a much wider spectrum of light to be absorbed, including infrared, visible and ultraviolet. A cell made from p-type GaN with added Mn or Co is transparent and black, whereas GaN without additions is not.Manganese and cobalt are 3d transition metals, which are elements in which the number of electrons in the 3d orbit (inside the outermost orbit) increases as the number of protons in the nucleus (and hence the atomic number) increases. Other well-known 3d transition metals include titanium (Ti), iron (Fe), copper (Cu) nickel (Ni) and zinc (Zn). The scientists tried several 3d transition metals with GaN and obtained good results with many of them, including manganese and cobalt. Other researchers have tried adding indium (In) to gallium nitride PV cells with the aim of narrowing the band gap to enable it to absorb a wider wavelength band of visible light.The prototype was demonstrated during a 90-minute lecture at the 57th Spring Meeting of the Japan Society of Applied Physics on March 19.center_img Citation: New PV cell generates electricity from IR and UV light (2010, March 24) retrieved 18 August 2019 from https://phys.org/news/2010-03-pv-cell-electricity-ir-uv.html © 2010 PhysOrg.com The PV cell prototyped at the Kyoto Institute of Technology by adding cobalt to a p-type GaN thin film and laminating an n-type material (right).

Scientists address manyelectron problem by modeling an infinite chain of hydrogen atoms

first_img(Phys.org)—For the first time, scientists have determined the equation of state of an infinite chain of hydrogen atoms, which tells the amount of energy each hydrogen atom has, given the bond length between adjacent atoms. Steady-state density functional theory This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. More information: Mario Motta et al. “Towards the Solution of the Many-Electron Problem in Real Materials: Equation of State of the Hydrogen Chain with State-of-the-Art Many-Body Methods.” Physical Review X. DOI: 10.1103/PhysRevX.7.031059 Explore further Journal information: Physical Review X © 2017 Phys.org But what is even more interesting for the scientists than the result itself is how they achieved it: by using 20 or so state-of-the-art computational methods that have recently been developed to analyze many-electron systems. The new results offer a first glimpse of what these methods may offer for understanding and predicting the properties of many complex materials, and ultimately designing completely new materials.The chemists and physicists behind the new study are members of the Simons Collaboration on the Many-Electron Problem, whose ultimate goal is to find methods to model and understand many-electron systems. These are basically any systems that—like an infinite chain of hydrogen atoms— contain large numbers of atoms or molecules, and, therefore, many electrons.Electron-electron interactions play a large role in determining a material’s properties, such as how well it conducts electricity and how hard or soft it is. This information is critical for future initiatives in which researchers design new materials with specific desired properties. Although it’s relatively easy to model systems with a few electrons, as the number of electrons grows, the number of possible states that a system can occupy grows exponentially. Modeling such systems then becomes increasingly difficult, since the electron interaction effects are so strong that even the best independent-electron theories break down.In order to model many-electron systems, researchers have developed several many-electron computational methods that rely on advanced concepts in mathematics and computer science, such as cluster embedding theory, Monte Carlo methods, and tensor networks. But so far, no method exists that can treat all many-electron systems systematically with high accuracy and low computational cost.

Credit: Mario Motta et al. Physical Review X. DOI: 10.1103/PhysRevX.7.031059 In the new study, the scientists used a linear chain of hydrogen atoms as the first benchmark system to test many of these new theoretical methods. By applying approximately 20 of the newest methods to the same problem, the scientists were able to validate and cross-check the results of each method. Although the entire process was computationally complex, it allowed the scientists to combine the strengths of complementary methods and determine the energy per atom to a high degree of accuracy. They could then compare the accuracy of individual methods, which revealed that many of the new methods achieved a high degree of accuracy by themselves. “There are several facets to this work,” Shiwei Zhang, a physics professor at the College of William and Mary and the paper’s corresponding author, told Phys.org. “It produced extensive data and comparisons, as a benchmark study was designed to do. It also spurred many algorithmic developments in the different methods, which resulted from the interactions and ‘friendly competition.’ Perhaps less obvious but most important: it brought people and algorithms together, helped focus the field, and pushed the community to work synergistically in the most productive ways.”The scientists are making the vast amount of data produced in this study available to other researchers, which will soon be available here. They expect that the data will be useful for analyzing the computational methods, benchmarking new methods, studying other many-electron systems, and gaining a deeper understanding of many areas throughout condensed matter physics, quantum chemistry, and materials science, among other fields.”One short-term goal is to determine the properties of the hydrogen chain,” Zhang said. “Surprisingly, even in this relatively simple ‘material,’ there are important questions for which we do not have definitive answers. We have computed the equation of state. But, for example, what are the electrical and magnetic properties? “More generally, we would like to expand such benchmark studies to more complex materials. We will continue to develop our computational methods and software. And of course we would like to apply them to tackle the most challenging many-electron problems in molecules and solids important to science and technology.”last_img read more

Overuse of electronic gadgets triggers early ageing Doctors

first_imgAccording to experts, “tech neck”, which leads to sagging skin, dropping jowls, and creases above the clavicle, seriously affects facial looks of the person by causing frown lines, undereye bags, and horizontal lines on the neck along with fat prominences.“People who bend down constantly for long hours while using any handheld electronic device, like smartphones, tablet or computers, are more likely to get wrinkles. The bending position while texting on mobile phones can cause neck, back and shoulder pain, apart from headache, numbness, tingling in the upper limb and pain in hands, arm, elbows and wrists,” said Vinod Vij, Cosmetic Surgeon, at Mumbai-based Fortis Hospital. Also Read – ‘Playing Jojo was emotionally exhausting’A recent report by the Internet and Mobile Association of India (IAMAI) had revealed that the number of mobile internet users in the country was expected to reach 371 million by June 2016. As much as 40 per cent of the users consist of youngsters between the age group of 19-30. Experts have said that the frequent forward flexion causes changes in the cervical spine, curve, supporting ligaments, tendons and musculature, as well as the bony segments, commonly causing postural change. Also Read – Leslie doing new comedy special with NetflixMohan Thomas, Senior Cosmetic Surgeon, Cosmetic Surgery Institute, said, “As people do not realise the negativity they are causing to their neck bone and the skin, tech obsessed people should take necessary steps to avoid the overuse of the electronic gadgets.” He said the overuse of smart phones causes shortening of the neck muscles. “Apart from shortening of the neck muscle it also increases the gravitational pull on the skin. Ultimately, this results in sagging skin, double chin, marionette lines (vertical lines from lips to chin) and loose jowls (drooping jawline).

Spencers now offers bread made from 2000yrold Roman recipe

first_imgKolkata: If you want to tickle your taste buds with almost 2,000 years old Roman bread? Then, here is the good news for Kolkatans as Spencer’s has prepared the historic bread with the same ingredients, the Roman bakeries might have followed in 79 AD.Internationally reputed bread maker Spencer’s in Kolkata, after a series of experiments, has successfully recreated Roman bread which was very popular in Pompeii. The city of Pompeii was destroyed during the eruption of Mount Vesuvius around 2,000 years ago. To celebrate 400 days of the inception of its Park Street store, the Spencer’s from Monday afternoon has started offering this historic Pompeiian bread to consumers. The bread will be available in a 400 gram pack at a cost of Rs 60 from 30 Spencer’s stores as well in the city from 30 October. Also Read – Rain batters Kolkata, cripples normal lifeA Spencer’s spokesperson said on Monday that in the Western world, there had been inquisitiveness about the carbonized loaves excavated from Pompeii many years ago. According to the chief chef, western bread makers like many of us wonder how the original Pompeiian breads might have been looked like, how they might have tasted or what ingredients might have been used by the then bakeries to prepare those loaves. The funny looking bread was called “Panis Quadratus” which was excavated in a fossilised state many years later. It is presumed that the city of Pompeii had been destroyed due to a volcanic eruption. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedAccording to a senior official of the Spencer’s, the Pompeii bread is prepared with ingredients like — whole wheat flour (Atta), wheat refined flour (Maida), wheat bran, extra-high dietary fibre, yeast, starter, salt and others. Researchers tell us that the professional bakers in Rome and Pompeii did not exist until 2 nd Century BC. According to historical sources, the ancient Roman breads were made of flour, whole-wheat flour, tepid water, salt and other spices. The preparation time of the bread during the Roman era might have remained up to 30 minutes.last_img read more

Why morning people should not work at night

first_imgIf you are a morning person, working in night shifts may affect you more, a study said.According to the study, morning persons demonstrate a quicker reaction time when solving unusual attention related tasks when working at night, but they are more prone to make errors.This may be the result of sleep deprivation and a relative increase in the time spent awake which negatively impacts the brain’s attention system, the researchers said.The study showed that morning persons completed their tasks quicker than the night persons, but with errors. Also Read – Add new books to your shelfOn the contrary, night persons were found to spend more time finishing their tasks. But, their level of accuracy in completing the task was higher, the researcher noted.“To deal with the most difficult test – resolving a conflict of attention – it was necessary not only to concentrate on the main visual stimulus, but at the same time to ignore accompanying stimulus that distract from the core task,” said Andriy Myachykov from Oxford University.Though night people turned out to be slower, they were more efficient compared to the early risers. Also Read – Over 2 hours screen time daily will make your kids impulsive“Our study demonstrated how night owls working late at night ‘sacrifice’ speed for accuracy,” Myachykov added.The results of this study may be useful for people who work night shift and could challenge the education system and human resources management in certain areas.For pilots, air traffic controllers, drivers, etc, attention, the ability to deal with large sets of data, and reaction time are all very important. During emergencies, these features could play a vital role.The study is available in the journal Experimental Brain Research.last_img read more

Idol preservation Metal wood gain priority over clay

first_imgHave you wondered where the beautiful idols of the Goddess Durga vanish once the pujas are over and the pandals dismantled? While some of these idols – a handful – are preserved by the state Government at various museums or parks or private collectors, the normal clay idols are simply immersed in the Ganges or other water bodies after Dussehra.Which idols of the Goddess are being preserved? Bhabotosh Sutar, the artist behind the Chetla Agrani Club puja – mentored by Bengal’s minister for Urban Development Firhad Hakim – has had about six of his Durga idols preserved so far. The beautiful idol he has carved out of a single, antique block of mahogany this time will also be preserved at the state government-run Eco Tourism Park in Rajarhat. This is going to be the third of his idols to be preserved at the park.”Other idols have been collected by ASI, Derek O Brien and ITC Shonar Bangla. These are all made from wood, metal and even terracotta. I’m hoping that my mahogany Durga(for Chetla Agrani) will be preserved well as a piece of public art”, Sutar told Millennium Post. Also Read – Add new books to your shelfThe trend started in 2011 when the Mamata Banerjee government came into power in Bengal. “A warehouse was built near the Golpark lakes where some idols were collected and preserved. But the state Government also does not have the infrastructure to preserve all Durga idols” Sutar said. Rupchand Kundu, whose idol at the Behala Friends Club is likely to be preserved this time at the state Government run Eco Park Club, said, “It has to be kept in mind while making the idol that this is not just a temporary construct but an artwork that needs to be preserved for the generations to come. In this idol, made from fly ash, I have shown that even ordinary waste can transform into something divine when light is thrown on it”, Kundu told Millennium Post. Also Read – Over 2 hours screen time daily will make your kids impulsiveIt all depends on the material used for making the idol. “Clay is difficult to preserve in the open air. However Durga idols which are made from wood or metals or fibre glass can be preserved in a museum or inside of a building as objets de art”, said eminent artist Subrata Gangopadhyay, an advisor to the Sreebhumi Sporting Club puja built around the Bahubali theme. Gangopadhyay has painted extensively on the Sindurkhela theme earlier which is associated with Durga pujas. Another artist whose idols have been preserved is Sanatan Dinda, though he mostly works with clay.last_img read more

We have to be influential enough to create jobs

first_imgSabyasachi Mukherjee just wanted to earn money to get on an airplane and travel the world when he entered the fashion industry, and went on to make a special place for himself by weaving traditional stories with threads of Indian culture through his creations. India’s ace couturier says he wants to make sure that he “comes up with something that the copy market can copy” that in turn creates jobs in the market. In an interview , the designer looked back to the time when he entered the industry and how a sense of responsibility towards the country and people who work for him has seeped in. Also Read – Add new books to your shelf”When I first started out, I wanted to make enough money so that I could get on an airplane and travel to any part of the world that I wanted to.

He is one of the few names in Indian fashion to participate at fashion weeks in Milan, New York and London. The designer, whose creations have been flaunted by the likes of actresses Shabana Azmi, Renee Zellweger, Reese Witherspoon, Aishwarya Rai Bachchan, Tabu, Sushmita Sen and Kareena Kapoor Khan, hails from Kolkata. He has lent his creativity in fashion to films such as Black, Guzaarish and Paa.Sabyasachi works closely with artisans to tell stories with his sartorial creations.”What’s good about the artisans right now is they are not being treated as artisans any more; they are treated as artists and there is a lot of respect, there is a lot of social and cultural respect that’s coming.”They are buying homes, their children are going to school, they have technology aiding them, they have business managers and accountants, they have CAs looking into their books. I think what they are doing is they are shaping themselves from fragile, small companies into strong robust businesses.”Sabyasachi has put in his creativity to use by creating ensembles for women, men and children. He says the chance to design wall coverings came at the right time.”I wanted to do something in interiors, but I also wanted to do it with one of the largest companies in the country .”What is he working on at the moment?”On a speech that I’m going to give at Harvard (University).

Calcutta University forms panel to counter plagiarism

first_imgKolkata: The Calcutta University (CU) has constituted a committee that will frame guidelines to check plagiarism.The committee has been formed according to the guidelines of the University Grants Commission (UGC) in this regard. The faculty council of the varsity has already approved the decision of setting up this committee. “There is a guideline on plagiarism framed by the University Grants Commission. But there should be a specific policy of all universities on the basis of these guidelines to curb the practice. The CU did not have any such guidelines. The researchers used to send their papers to the library following which the latter checked on certain aspects and prepare a report on the originality of the research paper. But we have been discussing for quite some time that there should be a specific guideline in this regard,” a senior member of CU teacher’s association said. The committee has deans of seven faculties and the librarian of the varsity.

Modi running communal campaigns for political gains says Abhishek

first_imgKolkata: All India Trinamool Youth Congress president Abhishek Banerjee on Saturday launched a scathing attack on Prime Minister Narendra Modi whom he accused of running an unabashed communal campaign to gain political dividends in the ongoing Lok Sabha elections.While addressing a rally at Aatghora High School Ground in Baduria under Basirhat Parliamentary constituency, Banerjee alleged that Modi has been trying to divide people on religious lines only to win the polls. He, however, asserted that the Prime Minister will suffer a humiliating defeat in the ongoing elections despite his tactically plotted communal cards. Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: Mamata”Modi has been trying to polarise the voters by creating a rift between the people belonging to various religious communities. His main objective is to trigger communal tension across the country. People here in Bengal are peace loving and they would thwart any attempt made by him or his party,” Abhishek added. Attacking the Prime Minister, he said: “He failed to deliver on all the promises he had made during the previous Lok Sabha elections. He promised ‘Achhe Din’ for the people by creating two crore jobs every year. Not a single person has benefitted from him. Instead of carrying out development projects, a party office in Delhi has been built at the cost of Rs 1,200 crore. The Modi government has not given a single penny to the Bengal government in the past five years.” Also Read – Lightning kills 8, injures 16 in stateAbhishek also criticised Mukul Roy without naming him and said: “All the thieves have taken refuge in the BJP. In the same breath, he also added: “If Madan Mitra had been put behind bars for three years only for taking photographs with Saradha group owner Sudipta Sen, why would Modi not go to jail despite having clicked photographs with Nirav Modi.” Sitting Trinamool Congress MP from Diamond Harbour, Abhishek urged the people of Basirhat to vote for Trinamool Congress so that party chief Mamata Banerjee can play a decisive role in the formation of the government at the Centre. Abhishek is contesting from Diamond Harbour seat. “Don’t cast your vote in favour of CPI(M) or Congress as they would strengthen the hands of the BJP. Help TMC to win in all the 42 seats so that a new government comes to power with Mamata Banerjee playing a crucial role. You have come to the rally in large numbers braving almost 40 degree Celsius which shows that you are with the TMC. This has to be reflected on the day of the election result,” he maintained. Abhishek was campaigning in favour of actor-turned-politician Nusrat Jahan who is contesting from Basirhat on a TMC ticket.

Marissa Mayer Mobile Was a Huge Missed Opportunity for Yahoo

first_img This hands-on workshop will give you the tools to authentically connect with an increasingly skeptical online audience. 3 min read Yahoo is a latecomer to mobile and CEO Marissa Mayer knows it.Speaking at the TechCrunch Disrupt conference in New York today, Mayer described mobile as one of Yahoo’s “biggest missed opportunities” and outlined what she’s done and plans to do going forward in order to keep Yahoo competitive in the mobile market.“Last year was really the year where we began to make our investment in mobile and we’re late and we’re behind,” Mayer said. “When I got to Yahoo, mobile was everyone’s hobby and it was no one’s job.”Since taking the helm, Mayer has rallied a team of more than 500 mobile designers and engineers dedicated to making Yahoo a leader in mobile technology. She said the company is looking to appeal to users’ daily habits – gaming and communication.”When you look at how people are spending time on phones … a lot of it is communications or games based. “Something like 50 percent of the top hundred [mobile apps] are games, so we do have a new games platform and we obviously have communication tools. We’re hopeful those communication tools like Tumblr, like Yahoo Mail will be up with the top apps.”Related: Shane Smith Wants to Be the Rupert Murdoch of His GenerationJust a quick look at Apple’s App Store shows just how far behind Yahoo is. Google Maps, Docs, Search and YouTube apps are all among the 20 most popular apps. Facebook has three apps in the top 20 – the main Facebook app, Messenger and Instagram. As of today, Yahoo’s Mail app was No. 43.Recent success on Tumblr—which Yahoo acquired for $1.1 billion—is a big step in the right direction and an example of something Yahoo has really been able to get right by improving the mobile interface and increasing engagement.Related: Google X Chief: We’re Using Technology to Get Technology Out of the Way“More than 58 percent of Tumblr users engage with sponsored content. Forty-eight percent of them actually reshare it because the branded content is so good, so authentic, so interesting,” she said.By the end of 2014 Mayer said Yahoo’s traffic will reach the crossover point with more users on mobile devices than PCs.“Mobile is approximately doubling along every metric we have. Traffic, revenue, users. Were up to 430 million monthly users on mobile so we have the largest mobile audiences in the world already,” she said. “Now it’s a matter of taking the content services that we have online and bringing them onto the phone in a really meaningful way.”Related: Ssshhhhh: Put the Kibosh on Annoying Twitter Users Without Them Knowing Enroll Now for Free Opinions expressed by Entrepreneur contributors are their own.

Merge Video and Audio on Windows

first_imgMerge Video and Audio on Windows by Martin Brinkmann on November 29, 2016 in Tutorials – 9 commentsIt is relatively easy to merge a video and an audio stream on Windows provided that the source files are not too obscure.I made the decision recently to try a couple of things on YouTube. One of them had me record video, and get someone else to do the talking. You would not want to listen to my heavily accented English so I figured it would be best to get someone else to do that for me.I would then merge the two, and upload the cut video with audio to Ghacks’ YouTube channel (yes such a thing exists).My requirements were simple: I wanted a free, easy to use program to add the audio file to the video. Anything else beyond that would be a bonus but not really required at this stage in time.Merge Video and Audio on WindowsWhile there are plenty of programs out there to merge video and audio on Windows devices, many are not that easy to use.Vidiot, an apt name for the desktop program, was the second program that I tried. The other crashed on me on first start and since I did not want to spend valuable time researching crashes, I decided to move on (one was VSDC Video Editor which looked great).The Vidiot interface is rather simple. You can load different video and audio files and they are automatically represented in the timeline in the lower half of the interface.You may preview the video at any time with a click on the play button, and move timelines around to make them fit.This makes it easy to make sure video and audio are in sync among other things.The one issue that you may have is that it is not clear right away how you select part of a timeline. This is useful if you need to cut a video or audio track so that the audio track matches the video.All you need to know is that you need to click on the timeline first. This is the starting point. Now hold down the Shift-key, and drag the mouse to the end location.You may then cut the selected part, or use Sequence > delete marked regions or delete unmarked regions to remove the part from the video.I suggest you play the video with audio before you start the conversion. Select Sequence > Render “project name” to render the video with audio and save it to the local system.Videos are saved as avi files in the same directory as the source video.The application supports several compositing options, including cropping, changing speed, scaling, rotating, adding transitions, trimming and more.You may want to check out the options of Vidiot at least once. There you find options to change starting parameters such as fps, video width or height, or video scaling mode among other preferences.Closing WordsVidiot is not a professional grade video editor but it is sufficient for light tasks. I’ll probably have to look for another program once I start getting the hang of it and want to add effects and better transitions to the videos. For now though, Vidiot is all I require.Now You: Which video editor can you recommend?SummaryArticle NameMerge Video and Audio on WindowsDescriptionFind out how to merge video and audio files easily using a simple, yet powerful for home use, video editor called Vidiot.Author Martin BrinkmannPublisher Ghacks Technology NewsLogo Advertisementlast_img read more

Whats in Store for Firefox in 2017

first_imgWhat’s in Store for Firefox in 2017? by Martin Brinkmann on January 04, 2017 in Firefox – Last Update: May 22, 2018 – 20 commentsThe year 2017 will be an interesting one for the Firefox web browser, Mozilla, and users of the browser. 2017 will see new technology being integrated in Firefox, and also some removed.The following guide lists those changes. It needs to be noted though that some may or may not happen. I mention that explicitly if that is the case so that you know that a change is not a done deal but something that could happen.Links to resources such as Bugzilla or Mozilla Wiki are posted whenever they are available. I encourage you to add more links or information in the comment section below.Firefox in 2017Electrolysis, or multi-process Firefox, became part of Firefox Stable in 2016. The process of enabling the feature to all users is still ongoing.The feature improves the browser’s stability and responsiveness, but will use more RAM.Mozilla plans ahead already, as the organization wants to increase the number of content processes in Firefox. The current situation is that there is only one content process. All sites open in the browser share that one content process. The use of additional content processes will improve that, but it seems unlikely at this point in time that Mozilla will switch to Chrome’s one content process per tab model anytime soon.Finally, strong sandboxing will come to Firefox once multi-process is available to all users. This moves Firefox closer to Chrome which offered sandboxing from the get-go. It is interesting to know that Firefox’s sandbox will be based on different technologies on supported platforms. The Windows sandbox will be based on on the Chromium sandbox, the Mac OS X sandbox on TrustedBSD MAC Framework, and the Linux sandbox on seccomp.Sandboxing will improve Firefox security significantly.The Tor uplift project is another ongoing process that will provide benefits to users of Firefox (and Tor, which is based on Firefox).Basically, what is happening is that some of the privacy-focused changes of Tor are integrated in Firefox directly. They won’t be enabled by default, but Firefox users who know about them can do so to benefit from them.A basic example is a feature called First Party Isolation which will be integrated in Firefox 52 and provides strong anti-tracking protection. Firefox users who want to enable it can do so by setting privacy.firstparty.isolate to true on about:config.The final bit in regards to browser stability and performance is Mozilla’s Quantum project. Firefox will become a lot faster with Quantum components. These components make extensive use of modern hardware features and parallelism. The main idea for 2017 is to replace some browser parts with Quantum components.Firefox Add-ons and WebExtensionsMozilla announced recently that it plans to make Firefox rely on WebExtensions exclusively at the end of 2017. The final date is not set in stone yet though, and there is a chance that things will be delayed to 2018.This has severe consequences for Firefox users who use one or more add-ons currently. All classic add-ons, won’t work in Firefox anymore once the change is made.This is big, bigger even than the switch to multi-process Firefox which also had its impact on add-ons.The main issue right now is that WebExtensions APIs are nowhere near the level of what the browser’s current add-on system provides.This means that some add-ons cannot be ported to WebExtensions right now. Mozilla plans to add more APIs as time passes by, but the deadline is looming over the heads of add-on authors.Ultimately, it is fair to say that WebExtensions will never be as powerful as Firefox’s current add-on system. This in turn will mean that some add-ons won’t be ported over to WebExtensions, at least not in their current form.Mozilla is also working on a new theming API. It will be more powerful than what light themes offer currently, but it too won’t be as powerful as Firefox’s current theming options.This and that in 2017Now that we have covered the two major areas, lets take a look at some other areas. Mozilla plans to rewrite the browser’s DevTools using HTML, CSS and JavaScript. It may host the DevTools on GitHub as individual add-ons. This would allow for faster updates and would entice non-Mozilla contributors to improve the developer tools further.Container Tabs may become a thing in Firefox. They are tested in Nightly currently, but it is not clear yet if they are uplifted to Firefox Stable.Containers have their own browser storage that is separated from others. This is beneficial to privacy, but also to have different identities open on the same site — think Gmail and two different mail accounts.The main difference to Firefox profiles is that container tabs work under the same profile. With that said, it is probably more of a niche feature though unless Mozilla gets the integration — and automation — right.Automation could help a lot. You could configure a tab for exclusive use for online banking, and another for shopping for instance. This would separate these activities from general browsing activities.Dropping Aurora?Mozilla might drop the Aurora release channel in 2017. This is not a done deal, and it may never happen. If the organization does it, it would bring new features more quickly from Nightly to Firefox Stable.It is unclear what would happen to the Developer Edition of Firefox. One option would be to make it the same as Firefox Stable.Mozilla Foundation MembershipsMozilla may introduce memberships in 2017. This would improve funding by making the organization less dependent on search engine money. Subscribers would gain benefits, but nothing has been mentioned so far in this regard. (thanks Callahad @ Reddit)Now You: What’s your take on Firefox in 2017?SummaryArticle NameWhat’s in Store for Firefox in 2017?DescriptionThe year 2017 will be an interesting one for the Firefox web browser as features like multi-process Firefox, Quantum and strong sandboxing will launch.Author Martin BrinkmannPublisher Ghacks Technology NewsLogo Advertisementlast_img read more

Customize colors in Windows using Classic Color Panel

first_imgCustomize colors in Windows using Classic Color Panel by Martin Brinkmann on May 16, 2017 in Windows – Last Update: July 30, 2017 – 17 commentsClassic Color Panel is a free portable program for Microsoft Windows devices to customize the colors used by various interface elements.The application is compatible with Windows 7, 8 and 10 operating systems. While that is the case, it is most useful on Windows 10 devices as Microsoft had the glorious idea to remove the Color Control Panel applet from the operating system.This leaves Windows 10 users with the (meager) color options provided under Settings > Personalization > Colors. Experienced users may manipulate colors for interface elements in the Windows Registry (under HKEY_CURRENT_USER\Control Panel\Colors), but that is probably not something that most users want to do let alone are aware of.Classic Color PanelClassic Color Panel improves the accessibility of the color customization options. You can run the program directly after installation. It displays a prompt on start that allows you to create a backup of the settings of the Registry. It is recommended that you accept that, as you may double-click on the Registry file at any time to restore the default color settings.The program interface itself links interface elements such as ButtonText or Background to colors. These colors are shown next to each element, and a click on the color opens a color picker that you may use to change it to another one.The app divides text colors and interface colors and displays each in its own column in the interface. A click on the three arrow icon displays even more interface elements that you can modify the color for.Colors are not changed automatically, which means that you may have to sign off and on repeatedly to test various color schemes before you find a suitable one.You do need to click on apply once you have made changes to modify the Registry values. The program prompts for a sign off, and if you accept, will sign you out immediately.The new color scheme is active right after you sign on again the next time. The program ships with a handy “default” button that you may click on to restore the default color scheme. Last but not least, you may also export the color scheme at any time. This can be useful if you want to apply it to another device or another user profile as well.The developer published examples for some of the interface elements on the site. While you may be able to identify some by name, you may find the images helpful to determine others.Closing WordsClassic Color Panel restores color customization options on devices running Windows 10. Windows 7 and 8 users may also use the program but it is less useful on those machines. It may be easier to use though, as it displays all color options in a single interface and makes customizing those a breeze.Summary12345 Author Rating3.5 based on 5 votes Software Name Classic Color PanelOperating System WindowsSoftware Category AdministrationLanding Page https://www.wintools.info/index.php/classic-color-panel Advertisementlast_img read more

Hide Programs from the Uninstall interfaces in Windows

first_imgHide Programs from the Uninstall interfaces in Windows by Martin Brinkmann on October 11, 2018 in Software – 7 commentsWindows users who want to hide certain programs from the uninstall interfaces of the operating system can use the freeware Hide from Uninstall List to do so.The free program includes options to hide individual programs or all of the programs from uninstall lists the operating system provides.Hide from Uninstall List is a free portable program for Windows that users can start right after download and extraction of the archive the program is distributed in.The program is compatible with all versions of Microsoft’s Windows operating system starting with Windows XP and comes with several interface languages that users can switch between from within the program window.Hide from Uninstall ListThe application displays the list of installed programs and apps in the interface on start. Select File > Languages to switch to another interface language if you don’t want the program to use the system language but another of the supported languages.Each program is listed with its name, publisher and current state. State indicates whether the program is listed under “programs and features” in the Control Panel and the Apps listing on Windows 10 devices.Right-click on any program and select “Hide from Programs and Features List” to hide it in those interfaces.Mark multiple entries at once to run the state changing operation on all of them at once.Note: While the program is no longer listed in the Control Panel or Apps listing in Settings, it is still listed in other locations such as on the hard drive or in the Start Menu.The main idea behind Hide from Uninstall List is to prevent the removal of the program on the system using default system tools.The only other option provided is to hide programs and features. This removes Apps & Features from the Settings app on Windows 10 and empties the entire Programs and Features listing of the Control Panel.Changes that you make are applied instantly. A click on the Programs and Features link in the program interface opens the Control Panel applet for verification.What is the purpose of the program?Experienced users may wonder why someone would want to use a program like Hide from Uninstall List. It is clear that it is not used to fully protect a program from being uninstalled as there are multiple ways to remove programs other than using the Apps listing or the Programs and Features listing.I think it is designed for users who share the PC with others or are supervised. It provides some level of protection from detection and removal. While that is not perfect, it may do for some users.Closing WordsHide from Uninstall List is a program that some users may like. The majority of Windows users may not see much of a use for a program of its kind though probably.Now You: What is your take on the program?Summary12345 Author Rating5 based on 2 votes Software Name Hide from Uninstall ListOperating System WindowsSoftware Category AdministrationLanding Page https://www.sordum.org/11081/hide-from-uninstall-list-v1-0/ Advertisementlast_img read more

Chromiumbased Edge Linux support and IE integration

first_imgChromium-based Edge: Linux support and IE integration by Martin Brinkmann on March 29, 2019 in Internet Explorer – 54 commentsMicrosoft’s upcoming Chromium-based version of Microsoft Edge has not been unveiled officially but leaks give us a good idea of what to expect from the new browser.Some features were overlooked in the initial reviews. When Microsoft launched the Edge browser, it made it a Windows 10 exclusive. While you could gain access to Microsoft Edge using a Virtual Machine, exclusivity meant that Edge did not get off to a good start.Windows 10 users could not sync data between Edge on Windows 10 and their mobile applications. This changed with the release of Microsoft Edge for mobile devices. The decision to release the browser for non-Microsoft operating systems but not the still-supported Windows 7 or Windows 8.1 did not sit well with customers who were still using these operating systems.The new Chromium-based Edge will be available for other platforms according to Microsoft. The company mentioned Mac OS X specifically but it is very likely that it will also be available for Linux.Probably the best indicator that Microsoft Edge will be available for Linux is found in Microsoft Edge itself. Load edge://flags and look at the compatibility information that is displayed next to each experiment.You find Linux listed there for many of the experiments and not only Windows or Mac. Microsoft did edit these, as you don’t find Chrome OS listed there or mobile operating systems.The listing is an indicator but no verification; there is none at the time. It is still up to Microsoft to release the new Edge for Linux. Chance is good that this is going to happen.Internet Explorer Tab inside EdgeThe second feature that slipped by initially is integration of Internet Explorer in Microsoft Edge. Windows Latest discovered the flag “Enable IE Integration” under Experiments which “enables hosting Internet Explorer in a tab”.The feature does not work currently as it appears to be in development at this time. The most likely explanation is that it may be used to load individual sites in Internet Explorer’s rendering engine in the Microsoft Edge browser.The current Microsoft Edge browser comes with an option to open a web page in Internet Explorer. You need to select Menu > More Tools > Open in Internet Explorer to do so. The new option, provided that it will load the web page in a tab in Microsoft Edge, would be more comfortable as you would not have to juggle between two browser windows as everything would happen in the Edge window.Now You: What do you expect from the new Microsoft Edge browser?SummaryArticle NameChromium-based Edge: Linux support and IE integrationDescriptionThe upcoming Chromium-based version of Microsoft Edge may support Linux and integration of Internet Explorer.Author Martin BrinkmannPublisher Ghacks Technology NewsLogo Advertisementlast_img read more
