General relativity has passed every time.īut it takes a strong gravitational field, like the one around M87’s black hole, to kick the tests up a notch. Those aspects of gravity have been tested with the way stars’ light is deflected during a solar eclipse for example, and the way laser light sent to spacecraft flying away from the sun takes longer than expected to return to Earth ( SN: 5/29/19). These additions are related to things like how light and mass travel in a warped spacetime, or how gravity makes time flow more slowly. In weak gravitational fields, like within the solar system, physicists can test whether “first-order” additions to Newton’s equations are consistent with general relativity or not. The more add-ons or factors added to a test, the more confidence there is in a result. If measurements of how gravity works in the universe deviate from those predictions, then physicists know general relativity is not the full story. General relativity predicts what those add-ons should be. Generally, physicists think of general relativity as a set of corrections or add-ons to Isaac Newton’s theory of gravity. But the new study is interesting because “it’s the first attempt at constraining a effect through a black hole observation,” says physicist Emanuele Berti of Johns Hopkins University, who was not involved in the new work. The results are on par with those from gravitational wave experiments like the Advanced Laser Interferometer Gravitational-Wave Observatory, which has detected ripples in spacetime from the merger of black holes smaller than M87’s ( SN: 9/16/19). So far so good for relativity, the researchers found when they performed this second-order test. That “can’t really be done in the solar system” because the gravitational field is too weak, says EHT team member Lia Medeiros of the Institute for Advanced Study in Princeton, N.J. Specifically, the researchers used the size of the black hole to perform what’s known as a “second-order” test of general relativity geared toward boosting confidence in the result. In a study published October 1 in Physical Review Letters, Psaltis and colleagues have used the shadow of M87’s black hole to take a major step toward ruling out those alternative theories. That question is key because it’s still possible that some other theory of gravity could describe the universe, but masquerade as general relativity near a black hole. That result, reported by the Event Horizon Telescope Collaboration, answered one question: Is the size of M87’s black hole consistent with general relativity?īut “it is very difficult to answer the opposite question: How much can I tweak general relativity, and still be consistent with the measurement?” says EHT team member Dimitrios Psaltis of the University of Arizona in Tucson. In other words, Einstein was right - again. That iconic image, of the supermassive black hole at the center of the galaxy M87 about 55 million light-years away, showed that the shadow closely matched general relativity’s predictions of its size ( SN: 4/10/19). The theory not only describes the way matter warps spacetime, but it also predicts the very existence of black holes, including the size of the shadow cast by a black hole on the bright disk of material that swirls around some of the dense objects. When the first-ever image of a black hole was released in April 2019, it marked a powerful confirmation of Albert Einstein’s theory of gravity, or general relativity.

Perhaps that’s because security is a universal concern that doesn’t need direct monetary incentives for developers to contribute to it. But objectively, that’s not been the case. You could argue under normal circumstances that LastPass has the better market incentive to produce a secure and user friendly password manager. Their apps, extension, and online services are all open-source. That means you’ve got to rely on their infrastructure and their will to continue operating the service.īitwarden, on the other hand is open-source from top to bottom. LastPass is a proprietary software and service. This is on top of the fact that Chrome already consumes a huge amount of memory, with LastPass making matters worse.īitwarden has desktop apps for Linux, macOS, and Windows as well as mobile apps for Android and iOS and browser extensions for just about all web browsers.īitwarden is everywhere we are and everywhere we can foresee finding ourself - whereas LastPass suggest you switch your browser to Chrome to continue using their service (seriously, ya’ll?) Open-source and self-hosting Sometimes you have to login to the web vault for an update to take effect or a share to show up. However, the LastPass extension for Firefox has been only getting more and more buggy with time.įirefox-the browser of choice for many people due to its relatively strong focus on privacy-clearly haven’t been a priority for LastPass.įor Google Chrome browser the issue we’ve found is that it’s very slow and buggy. LastPass have been pretty good about being available in every web browser and on every platform. Platform availabilityīitwarden and LastPass both offer free hosted password management services with clients available for multiple popular devices, operating systems, and browsers. We’ll go through a few points that we feel were important to us when deciding on a password manager, and compare how Bitwarden vs LastPass lives up to our expectations. The Search for the perfect Password management app The password manager we now use and recommend is BitWarden. So we started to search for alternatives and now, after months of using one of these alternatives, we are ready to recommend a solution that we feel passes muster at a higher level. However, LastPass had some flaws that were getting worse with time and undermining our confidence of its security:Ĭ) reports of decreasing quality of support after its acquisition by LogMeIn (though we never had occasion to request support ourselves)ĭ) Resource hogging of your browser since its introduction of JavaScript (aka, the Devil) It also has a Chrome extension that works somewhat slowly and buggily, but works all the same. It’s convenient, allows you to share passwords (and accept shares). In fact, we used Last Pass for years before switching to another solution. LastPass is one of the most popular password management apps in the world, and has some (but not all) of these features. On top of rock solid security, you need the ability to share data across your team. To say nothing of the legal woes you would likely encounter shortly thereafter. On the other hand, your password management app MUST be safe and reliable.Īfter all, a hack of your customers’ sensitive details could have a huge negative impact on your customers and their customers. You’ve got hundreds of accounts and passwords.Īnd you need a user friendly password manager with good integration with all the web browsers and mobile devices you and your team are using.

Life became more better when I discovered how to use ImageMagick.īut I had hard luck finding a proper GUI version of this. XnView has a Contact Sheet tool, but I never liked it. The Contact Sheet tool was one of the last reasons I continued to use Photoshop. (I've got some idea about it from your AppImage recommendations, but deeper knowledge will be gold for me). I would love to know if you use any app for that.Īnd I would really appreciate it if you could share your Photography workflow. I'm searching for it, I'm trying to make PureRef generate it, but it's a little messy. I've left Photoshop for good, so no more Photoshop Contact Sheet option for me. What do you use for generating contact sheets or thumbnail sheets in Mint? I would love if these features come to Pix or Xviewer in future, a little more customization and a little more editing tools will seal the deal for me. I use feh when working from a terminal, and for single images I sometimes use Pix or Xviewer.īut I don't think Pix or Xviewer are going to get any attention anytime soon. At one time Gwenview was my favorite for this work, but then it got all wobbly and I gave up on it.Īnother image viewer I use somewhat regularly is Mirage - it is a no-frills image viewer, and I use it when I want to look at a single image quickly. I like to use an image viewer that has a histogram and has a file browser that allows me to increase the size of the thumbnails easily. One of the first steps in my photography workflow is to review the images and cull any that will not be processed. Most of the time my default image viewer is XnView MP or Geeqie. I have viewers I use for specific tasks, but frequently I use Open With and chose one that suits my mood at the moment. It is nothing that practical or sensible. Is it for support for different image file formats, like some obscure formats? I have digikam as an image browser here, but XnView Mp might be a suitable candidate for the image viewer standards.īenTrabetere, what do you think is suitable for my case? I've the AppImage here in Linux, but if I don't integrate with the system, I don't know how I could select it as preferred application so images by default open with it. I also used XnView MP in Windows but I used it as an image browser, it's quite capable. Download the file, make it executable, and run. Scroll about 3/4 down the page and look for XnView_2.17-x86_64.AppImage. If you do not want to install the XnViewMP, it is also available as an AppImage at. It is fast and responsive, and it is free for non-commercial use. It is a very capable image viewer, it has a basic set of tools for editing images, batch processing tools for renaming and converting images, and it can be customized.
