Following up on the announcement of a SpaceX developed and launched, partially Google and Fidelity Investments funded ($1 Billion worth) 4,025 satellite internet constellation.

The satellites and ground receivers are said to use electronically steerable phased array antennas, a technology usually associated with military radars. These multi-element antennae have now been shrunk to the size of a silicon chip.

This about pending spectrum "discussions" is a good place to start.

In 5G proceeding, SpaceX urges FCC to protect future satellite ventures

Space Exploration Technologies, otherwise known as SpaceX, the space transport company founded by billionaire Elon Musk, wants the FCC to consider not only existing but future innovative uses of Ka-band spectrum before committing to a proceeding that might create barriers to entry.

The company made the comments as part of the FCC's Notice of Inquiry (NOI) on technical and service rules for 5G in bands above 24 GHz. Reply comments on the proceeding were due last week. Several other satellite-related entities, as well as wireless industry vendors and service providers, filed comments as well.

SpaceX pointed out that it recently announced plans to build a network of 4,000 non-geostationary orbit (NGSO) communications satellites, which it will manufacture, launch and operate. It plans to hire a large number of skilled workers at a new satellite manufacturing center in the Seattle area.

While well established as a launch services company with NASA contracts, SpaceX will be a new entrant in the satellite communications space, seeking to provide low-cost, high-speed broadband Internet service worldwide, including to end-users in the United States. SpaceX said its network will be operating in higher frequency bands, including the Ka-band spectrum at issue in the current FCC proceeding.

The company notes that the record in the proceeding firmly establishes that satellite operators have launched or are developing satellite systems to operate in the Ka-band frequencies above 24 GHz. For its part, SpaceX says it will join the ranks of Ka-band spectrum satellite operators "in the near term" as it begins to test and deploy its network of satellites.

The Satellite Industry Association (SIA) has asked the commission to carefully consider the potential impact on incumbent satellite services in bands above 24 GHz from possible sharing with new 5G services, and SpaceX echoed those concerns.

SpaceX urges the commission to take into account new satellite entrants and not just incumbent satellite operators and their existing or planned operations. "SpaceX is committed to introducing a new NGSO network in the Ka-band, further enhancing competition and innovation for satellite services. Any adopted 5G policies should contemplate the continued march of innovation and new entrant business models so as to enhance competition and expand consumer choices in the Ka-band," the company said.

The company also noted that even in satellite uplink bands, there are potential challenges to sharing between intensive, high-power terrestrial operations and satellite services. Satellite earth station uplink operations have the potential to cause interference into terrestrial receive antennas, and aggregate interference from terrestrial operations could adversely affect satellite receive operations. Such effects are particularly important to consider in the context of NGSO operations, where steerable earth station transmit antennas would have a wider geographic impact and significantly lower satellite altitudes magnify the impact of aggregate interference from terrestrial transmissions, the company said.

This announcement and the obvious commitment is stunning. Steerable phased array radar has been around quite some time now (early 80's for my first exposure) and has advanced exponentially. Bandwidth allotment and power levels are going to be a snake pit, and as such, regulation will be crucial as the technology is already proven. I see the filing as a big issue in so much as a notice to the old guard that new entrants with the capital are here now and everyone has to share their candy. Will see how the FCC handles this or if sides are picked. I assume the FCC was well aware this day would come and are ready for this...Internet supply will change over the next decade for sure...Great news...and outright BOLD...Cheers...

Can SpaceX Internet Satellites Succeed Where Google and Facebook Failed?

Elon-Musk-SpaceX.thumb.jpg.2ca11de41aecc

SpaceX's plans to beam Internet access from space is just one item on the long list of ambitious and possibly world-changing projects that Elon Musk and his companies are working on right now. But while there are plenty of tough challenges facing SpaceX in its efforts, the competition for the higher ground has been self-winnowing, despite the rewards to any group that can make cheap, reliable Internet a global phenomenon.

Musk announced his plan for a network of thousands of satellites to beam the Internet to the Earth earlier this year. Using some of the $1 billion it raised in January, it will start manufacturing satellites in a factory near Seattle.

One notable fact about the investment is Google's involvement. Google had made much of its own plans for an Internet satellite network, even hiring OneWeb founder Greg Wyler to run its satellite division. But money and other delays frustrated Wyler to the point that he decided to leave Google and start WorldVu Satellites to pursue his vision. His company is now backed by Richard Branson's Virgin Group.

 

 

Facebook had made its own plans to send up satellites that would deliver the Internet from space, but recent reports say that plan is on indefinite hold. Facebook has also, like Google, bought a drone company that might help it send Internet access from the sky, but hasn't done much in that regard either. There's no doubt that the social media giant will be keeping an eye on Internet satellite developments though. The company's Internet.org initiative, designed to bring the Internet to places and people who don't have any access at all, would benefit immensely from being able to provide coverage from orbit.

The most important factor, besides the technical ability, is the cost. Designing, building and launching a satellite can cost hundreds of millions of dollars. Putting up hundreds of them, even if they are all the same design, presents a daunting bill to pay. The solution sought by Musk, Wyler and others working on the project all ultimately comes down to figuring out how to make the whole process more inexpensive. SpaceX's main mission of reusable rockets is an obvious solution to making the flights cheaper, and reusable rockets is very much the focus of other aerospace companies. Unfortunately, SpaceX has yet to successfully land a rocket in good enough shape to be reused. That's going to be a necessary part of any plan to put up hundreds of linked satellites without going bankrupt.

Just as important is working out how to lower the cost of making the satellites themselves. Musk and the SpaceX team have talked about using the latest advances in software and circuitry to build relatively small, durable satellites in the Seattle plant. If the satellites are cheap and the rockets they go up in can be reused and of course if all the technical issues can be resolved, SpaceX-style Internet might very well be how we all access the Internet someday. And the geo-stationary orbits would definitely put the network ahead of current satellite offerings, which are higher in orbit and offer a wider area of coverage, but with slower service.

While rural areas that have little or no Internet access might automatically want to sign up, SpaceX Internet will have to offer something extra to get people who already have easy access to switch. But if it's cheap enough, Musk's stated confidence in the project could be borne out.

It's all very risky, but Musk knows what it's like to gamble at laying the foundation for a whole industry. Tesla Motors and its network of charge stations and open-source patents testify to that. And Musk's focus on SpaceX's success promises that this project won't be tabled over the costs and technical difficulty that ended similar projects at Google, Facebook and elsewhere.

Elon Musk Wants to Launch 4000 Satellites to Provide Global Internet

But earlier this month, SpaceX filed a request with the US Federal Communications Commission for permission to encircle the planet with telecom satellites capable of beaming the Internet to anywhere on Earth.

The technology for satellite Internet has existed for a while, but has suffered practical setbacks. The distance at which most satellites orbit isn't exactly conducive to reliable service. Placing satellites in low Earth orbit - as SpaceX plans to do - allows for better connections, but decreases range.

Google - which has now invested in SpaceX's efforts - announced a similar plan in 2014, and estimated it would need 180 satellites in order to span the whole planet. But Musk has an even grander strategy. SpaceX's plan calls for 4,000 satellites to remain in orbit.

How much is all of that going to cost? The company hasn't officially released any estimates yet, but Google said it would set aside over $1 billion. In January, Musk told Businessweek that he expected the system to reach at $10 billion.

Still, SpaceX may have an advantage. With its primary focus on aerospace, SpaceX could streamline the launch process. Whereas any competitors would have to rely on third party entities to launch its satellites, SpaceX can use its own rockets.

And SpaceX isn't the only one trying to elbow its way into low Earth orbit. OneNet, founded by Greg Wyler and backed by Richard Branson's Virgin Group, has already seized a number of licensing rights for its own satellite Internet project.

"Greg has the rights, and there isn't space for another network," Branson told Businessweek. "If Elon wants to get into this area, the logical thing for him would be to tie up with us and if I were a betting man, I would say the chances of us working together rather than separately would be much higher."

I am sure that the SpaceX venture group will get their own licences.........:)

Dispute settled nicely.......

Qualcomm, SpaceX reach agreement that puts super-fast broadband on planes one step closer

 

Thanks to an agreement that Qualcomm (NASDAQ:QCOM) and SpaceX reached, the industry may be one step closer to realizing the vision of providing every passenger on planes with simultaneous access to streaming video, including live news.

That was one of the goals of engineers at Qualcomm when they set out to provide the technology that would allow for fast broadband on planes. In a proceeding before the FCC, Qualcomm, Gogo Wireless, Inmarsat and others are pushing for the FCC to auction 500 MHz in the 14 GHz band for air-to-ground (ATG) wireless services for airline passengers. The companies argue that in-flight broadband services do not pose a danger to airline passengers and personnel, and that a new ATG system would fortify existing terrestrial- and satellite-based systems for in-flight Internet access.

However, SpaceX, the venture headed by Tesla Motors founder Elon Musk, raised concerns last summer. SpaceX plans to operate a nongeostationary satellite orbit (NGSO) fixed satellite service (FSS) system that will use, among other frequencies, the 14.0-14.5 GHz band that has been proposed for new air-ground service. SpaceX was concerned about the potential for the new air-ground service to interfere with SpaceX's 14.0-14.5 GHz band operations.

 

Qualcomm had previously stated that the proposed air-ground system would account for less than 1 percent of the rise over thermal (RoT) for NGSO FSS systems. When SpaceX substituted its beamwidth, gain and G/T figures for the figures that had been assumed by Qualcomm, it found that the air-ground system would in fact account for more than 6 percent of the RoT for SpaceX's NGSO FSS system.

After a series of discussions, the two companies reached the conclusion that it is possible to field an air-ground mobile broadband (AGMD) system that sufficiently protects SpaceX's NGSO system. "SpaceX and Qualcomm agree that, given that, at present, the AGMB service will be the only non-primary use of the band, the AGMB operator shall control RoT to NGSO satellite systems to ensure that aggregate interference from the AGMB service accounts for no more than 1 percent RoT of the FSS link budget set out in ITU Recommendation S.1432," the companies said in a joint filing to the FCC.

"We're delighted" that they were able to reach a proposal that is satisfactory to SpaceX, which may or may not end up being a rival to the OneWeb satellite program that Qualcomm is supporting along with Richard Branson's Virgin Group, according to Dean Brenner, senior vice president, government affairs, at Qualcomm. "We don't know that SpaceX and OneWeb are actually going to compete," he told FierceWirelessTech. They might have completely different business models and offer different services.

"We're just looking at the technologies and systems that are on the drawing board," Brenner added. "It does show that people of good faith, when working together on technical issues, even from different companies that have different business objectives, can work together and reach a consensus."

Qualcomm is optimistic that an auction will be held in a timely fashion and that if everything were to go according to plan and smooth sailing, it could see its technology deployed on planes within two or three years. It's unknown who ultimately will deploy it, but it's possible mobile operators could get involved. Last year, T-Mobile US (NYSE:TMUS) and Gogo started offering free in-flight texting and voicemail to T-Mobile customers on Gogo-equipped U.S. aircraft.

While various offerings advertise different levels of service on planes -- JetBlue uses satellite service provided by ViaSat to offer streaming-friendly service to its passengers -- Gogo is primarily designed for web browsing, email and corporate VPN access. Because of capacity limitations, Gogo doesn't allow for video downloads, in-flight file transfers or streaming media, among other things. That is going to change with future iterations of its technology, but the baseline, when Qualcomm engineered its next-gen technology, was to allow all the passengers on the plane to stream video.

SpaceX is skipping Microsat 1a and 1b and moving straight to Microsat 2a and 2b; larger, more powerful and testing to multiple fixed and mobile ground sations. 400 kg with 7-10 kW of power, and a bunch of goodies including intersatellite laser relaying. Orbit raising and deorbit by advanced, SpaceX built, Hall effect electric thrusters.

Quote


SpaceX had previously been granted authority for two other experimental satellites (Microsat-1a and -1b) operating with different orbital parameters in the 2GHz, 8 GHz, and 14 GHz bands. See Call Sign WH2XWB, File No. 0356-EX-PL-2015 (granted July 22, 2016). Because SpaceX has made revisions to the design of its hardware and constellation since it applied for that authorization, it has opted to seek authority for different experimental satellites that will provide a better test bed.

Narrative Summary

Space Exploration Technologies Corp. (SpaceX) is a U.S. space technology company that designs, manufactures, and launches advanced rockets and spacecraft. The company is headquartered in California, and has more than 6,000 employees based at various facilities around the United States, including California, Texas, Florida, Washington, and the District of Columbia.

On November 15, 2016, SpaceX applied to the U.S. Federal Communications Commission (FCC) for operating authority for a constellation of non-geostationary orbit (NGSO) satellites for provision of broadband services. As a development step towards this initiative, SpaceX seeks authority to launch and operate two test and demonstration satellites over the course of 24 months. These are experimental engineering verification vehicles that will enable the company to assess the satellite bus and related subsystems, as well as the space-based and ground-based phased array technologies. The company may seek further authority for subsequent test and demonstration satellites.

The first phase of testing will include two satellites: Microsat-2a and Microsat-2b. These two satellites are intended to be launched as early as 2017. Both of these satellites will be deployed in one mission aboard a SpaceX Falcon 9 launch vehicle into an orbital plane of 514 km circular at 97.44 degrees inclination. After insertion, the satellite orbits will be raised to the desired mission altitude of 1125 km circular. The designed lifetime of each satellite is six months. If this lifetime is exceeded, SpaceX plans to continue operation until such time as the primary mission goals can no longer be met, at which point the spacecraft will be deorbited. Both Microsat-2a and Microsat-2b are identical in their construction and operation.

The primary structure for the Microsat-2a and -2b test spacecraft will be a box design measuring 1.1m x 0.7m x 0.7m and carries the spacecraft flight computer, power system components, attitude determination and control components, propulsion components, GPS receiver, and broadband, telemetry, and command receivers and transmitters. The primary bus is mounted on the payload truss system, which also carries communications panels, inter-satellite optical link transmitters and receivers, star trackers, and a telemetry antenna. There are two 2x8 meter solar panels. Each demonstration spacecraft has a total mass of approximately 400kg.

The attitude of each spacecraft is 3-axis stabilized, and is dynamically controlled over each orbit to maintain attitude position for two pointing modes of operation: broadband antenna (antennas to nadir for testing) and solar array (solar arrays facing sun for charging). Power is provided by solar panels designed to deliver sufficient power at the predicted end of spacecraft life to not impair any test objectives. The Thermal Control System ensures that components are kept within operational temperature ranges.

SpaceX adds a big new lab to its satellite development operation in Seattle area

SpaceX has taken on a 40,625-square-foot facility in Redmond, Wash., that will become a research and development lab for its ambitious satellite operation.

The warehouse-style space in the Redmond Ridge Corporate Center, owned by M&T Partners, is slated for a $2.1 million interior remodeling job, according to a permit application filed last month with King County.

SpaceX is already using a 30,000-square-foot office building thats about a 10-minute drive away in Redmond.

Setting up the lab, and hiring the engineers who will work there, marks a significant ramp-up for SpaceXs presence in the Seattle areas Eastside region. The California-based companys billionaire founder, Elon Musk, established the Redmond operation in 2015 to develop satellites that would provide global internet access.

Earlier this month, The Wall Street Journal reported that the 4,425-satellite constellation is one of the keys to SpaceXs long-term business plan  and Musk himself has said satellite revenues would fund his vision of sending thousands of settlers to Mars.

When Musk unveiled the plan in Seattle, two years ago, he said the satellite engineering operation could eventually employ maybe 1,000 people. The companys total employment is in the range of 5,000.

SpaceX hasnt publicized how many people are now working in Redmond, but the company is listing more than 60 open positions there, including spots for hardware and software engineers, satellite system engineers, designers and project managers.

Last November, SpaceX laid out the details for the satellite constellation in a filing with the Federal Communications Commission. Previously announced schedules have called for the first wave of satellites to be deployed in the 2018-2020 time frame.

The companys job listings suggest that satellite components will be built and integrated for testing at the Redmond lab. The Puget Sound Business Journal said there were rumors that a manufacturing plant eventually might be put in Kent, Wash., but SpaceX spokesman John Taylor said the company has made no decisions about satellite production facilities.

Debris and disposal

 

Quote

>
In this regard, it is worth noting that the VLEO Constellation offers even greater assurances against the creation of orbital debris. Its orbital characteristics have been chosen in order to maximize the spacing between satellites and thereby preclude the risk of conjunction. Moreover, at this very low altitude, atmospheric drag will quickly trigger the demise of any debris, whether released by a VLEO satellite (in the very unlikely event that such a release occurs) or caused by some other source. Thus, for VLEO satellites, the orbital characteristics themselves create an essentially self-cleaning operating environment, providing an additional layer of protection over the measures described below.

Spacecraft Hardware Design

SpaceX has assessed and limited the amount of debris released in a planned manner during normal operations, and does not intend to release debris during the planned course of operations of the SpaceX System. SpaceX is also aware of the possibility that its system could become a source of debris in the unlikely case of a collision with small debris or meteoroids that could either create jetsam or cause loss of control of the spacecraft and prevent post-mission disposal. SpaceX is undertaking steps to address this possibility by incorporating redundancy,shielding, separation of components, and other physical characteristics into the satellites design. Tanks are designed to suffer impact penetration without explosive consequences, while batteries are shielded and have isolation features to prevent cascading failure from impacted battery cells to other battery cells. SpaceX will continue to review these aspects of on-orbit operations throughout the spacecraft manufacturing process and will make such adjustments and improvements as appropriate to assure that its spacecraft will not become a source of debris during operations or become derelict in space due to a collision. 

Minimizing Accidental Explosions

SpaceX is designing its spacecraft in a manner that limits the probability of accidental explosion. The key areas reviewed for this purpose will include rupture of propellant tanks and batteries. The basic propulsion design (including a dual wall shielding effect from the bus walls), propulsion subsystem component construction, preflight verification through both proof testing and analysis, and quality standards will be designed to ensure a very low risk of tank failure. A burst disk ensures that sudden failure of propulsion containment cannot overpressure and fragment the spacecraft. During the mission, batteries and various critical areas of the propulsion subsystem will be instrumented with fault detection, isolation, and recovery (similar or in many cases identical to flight-proven methods utilized onboard the SpaceX Dragon capsule for its missions to ISS) to continually monitor and preclude conditions that could result in the remote possibility of energetic discharge and subsequent generation of debris. Through this process, SpaceX will assess and limit the possibility of accidental explosions during mission operations and assure that all stored energy at the end of the satellites operation will be removed.
>
>
Post-Mission Disposal

Each satellite in the SpaceX System is designed for a useful lifetime of 5 to 7 years. SpaceX intends to dispose of satellites through atmospheric reentry at end of life. As suggested by the Commission,39 SpaceX intends to comply with Section 4.6 and 4.7 of NASA Technical Standard 8719.14A with respect to this reentry process.
>
>
Post-Mission Disposal  VLEO Constellation

SpaceX anticipates that its VLEO satellites will reenter the Earths atmosphere withinapproximately one month after completion of their mission  much sooner than the international standard of 25 years. After the mission is complete, or all propellant is consumed, the spacecraft will turn off its ion thruster, and be reoriented to maximize the vehicles total cross-sectional area. The spacecraft will also passivate itself by de-spinning reaction wheels, drawing batteries down to a safe level and powering down. Due to the VLEO Constellations very low altitude at the edge of the atmosphere, re-entry after end-of-life is anticipated within a matter of weeks. SpaceX has conducted an assessment using NASAs DAS which indicates a total spacecraft Risk of Human Casualty rate of between 1:17,400 and 1:21,200, depending upon operational altitude for the VLEO satellite  satisfying the requirement of 1:10,000 established by NASA. This analysis will be conducted regularly throughout the spacecraft design life cycle to ensure continued compliance. The results of the analysis done to date are included on the following pages.

Google patent filing hints at how SpaceX’s satellite broadband network could work

 

BY ALAN BOYLE on March 8, 2017 at 2:10 pm

When it comes to providing global broadband internet coverage, two satellite constellations in low Earth orbit are better than one. At least that’s the implication of a patent application filed by an inventor who used to work at Google and is now part of SpaceX’s Seattle-area satellite operation.

Mark Krebs’ concept is described in an application that was filed last September, published by the U.S. Patent and Trademark Office in January, and picked up this week by PatentYogi’s Deepak Gupta. It calls for setting up two sets of satellites orbiting at different altitudes with different inclinations.

https://patentyogi.com/wp-content/uploads/2017/03/US2017005719A1.pdf

The scheme brings a couple of advantages: It eases the way for putting up thousands of satellites in orbits that cross over each other without having to worry about the threat of collision. The orbital arrangement also makes it easier to provide overlapping coverage for customers down below. That allows for a smooth handoff from one satellite to another, and provides more of a backup in case a single satellite goes offline.

The higher-orbiting constellation provides wider coverage, while the lower-orbiting constellation provides higher bandwidth.

“The satellites are arranged to provide at least 75 percent coverage of the Earth at any given time,” Gupta says in a YouTube video describing the scheme.

 

 


Krebs’ move from Google to SpaceX suggests that this is more than a blue-sky concept: Back in 2015, at around the same time that SpaceX’s Elon Musk announced the establishment of the satellite operation in Redmond, Wash., Google and Fidelity invested $1 billion to back the company’s effort to create a 4,425-satellite constellation for internet service. That meshes with the scale of the system described in Krebs’ application.

SpaceX is expanding its presence in Redmond, stoking suspicions that the satellite operation will soon raise its profile. Musk has said he sees the potential revenue from the satellite system as a significant contributor to his long-term vision of establishing cities on Mars.

Yep, and not just for Human use either. The DSN would benefit greatly from a derivative of this where the orbital plane is near the ecliptic. Vastly improved signal quality -- not necessarily speed, but bandwidth. Imagine a future probe being able to send data back at 3 mb/s or even 10 mb/s instead of the 30 kb/s. A derivative type of DSN based upon this application could enable those speeds. :yes:

    • Why you need to take back control of your synced passwords and how to go about doing that by Paul Hill Credit: Pixabay Last month, when Google decided to introduce daily and weekly caps for Gemini, it reignited an anxiety of mine, that you can’t really depend on service providers to maintain features forever, and it got me looking into free software (as in freedom) in other areas too. One app I quickly came across was KeePassXC on desktop and KeePassDX on Android as an alternative to password manager lock-in within the Chrome or Firefox ecosystems. I personally like to switch around with browsers, and using either password manager is inconvenient, so something like KeePassXC was interesting to me. The main issue with it now is syncing; I was not sure how to do that. After a bit of research, I came across Syncthing, a tool I was vaguely familiar with but had never used because it seemed complicated. However, I was completely wrong, and honestly, I think everyone should use it if they use multiple devices. It essentially lets you share folders peer to peer across all of your devices, no cloud services that you don’t control necessary! And it was fairly simple to set up, if not a bit clunky. Since setting it up, I’ve also started using Syncthing to back up other apps too, so don’t think it’s limited to just saving password databases. You can use it for pretty much anything you use Dropbox or Google Drive for. Before continuing to talk about those apps a bit more, let’s walk back a bit and talk about browser sync. Ever since the late 2000s and early 2010s, really, since we have been using smartphones, browser sync has been a necessity of life. I don’t know about you, but I have hundreds of passwords saved. For the most part, they’re all unique, so I don’t remember them and rely on software to manage them for me. Until recently, I’ve relied on password managers in Chrome and Firefox, but what I always found annoying was that it can be hard to transfer them between browsers. Sure, on Windows it is simple enough, but on Linux, exporting bookmarks has been temperamental. It works OK nowadays, but not too long ago, Chrome required you to enable exporting passwords in chrome://flags. The situation is even worse on mobile; there is no exporting or importing of passwords of any kind. You literally have to do it on a desktop, which is incredibly annoying in our mobile-first world. Sync also lets us take out bookmarks, history, tabs, and autofill data easily. To enable sync, it’s just a matter of signing into the browser once, and it handles the rest. It’s nice and easy. Obviously, all this has some issues, including those I’ve outlined above about it being hard to transfer data between browsers, but also things such as account suspension, lost account passwords, and other lock-in mechanisms, such as passkeys, being tied to a specific browser. On a sidenote, I have just removed all of my passkeys because they can make it harder to move browsers. I think the biggest threat to your synced passwords, especially if doing this with Google, is having your account suspended. I don’t ever expect mine to be suspended, but you do hear horror stories on Reddit where people lose access to their Google accounts. Imagine if you have hundreds of passwords, then suddenly lose access to them because Google froze your account, what would you do? So yes, it can be nice to use these syncing services for their convenience, but they also have risks. You may have seen me going on about free software quite a bit in my editorials. It’s essentially a concept championed by the Free Software Foundation. It’s software under particular licenses that grant you four freedoms: run the program for any purpose (0), study and change the source code (1), redistribute copies to others (2), and the freedom to distribute modified copies to others (3). For example, if there is an app I use and one day it gets abandoned by the developer, I can keep running it or even clone the software and continue developing it. Look at the myriad of cool services Google has run over the years before killing them. You can’t take the source code for those because they are proprietary, for the most part. Both KeePassXC and Syncthing are free software, so I get the freedoms listed above. In my use case where I’m syncing a database full of my passwords, I also get proper ownership over my data, there is no losing access to the database due to a frozen account, I can access the code of the tools I’m using, and I can get support from real people online if I run into issues, rather than having to consult a vague help page from an opaque company. With the KeePassXC password manager, you create a .kdbx file, which is what will be synced between devices. KeePassXC has cross-platform apps and also has browser extensions so that the browser can fetch passwords from the database once it is unlocked. Meanwhile, Syncthing is a peer-to-peer file sync tool where you can select folders to sync between your devices. Just pop files in the folders you choose, and then they will be available across your other devices whenever they come online. Syncthing is resilient as it works over both LAN and the internet and only ever sends content between your devices, never to a third-party server somewhere else. By combining these two pieces of software, you can essentially replicate the browser sync functionality. I have had a weird, conflicting issue where a new file is appearing, but it doesn’t seem to be impacting my main password database, which is updating between devices just fine. If you want to get a setup similar to what I have, you will need to go here to download KeePassXC for your computer. Once you have that, you will need to download your passwords from your web browser to a CSV file. In Chrome, you can type chrome://password-manager/settings into the URL bar, and you should see an option to download your passwords under Export Passwords. This will give you the CSV file you need for importing into KeePassXC. If you use a different browser, just use a search engine and type “browser-name export passwords” and muddle along. In KeePassXC, you’ll want to press Import File from the home screen, select the CSV file, and create a new database from it. On one of the screens of the wizard, there will be a Title field with a drop-down selected to none. Change this to Title and continue. You’ll select a name for the database, the encryption level (the defaults are fine), and then you will pick a password. I would choose four unrelated words that are easy for you to remember, as you’ll be typing them fairly often to access your passwords. When you have all your passwords in your new database, you will want to set up the browser extension so that your browser can fetch passwords from KeePassXC. Rather than explain how to do that here, refer to KeePassXC’s guide on how to set it up properly. Once you’ve got that set up, you want to install KeePassDX on Android. You can grab it on the F-Droid store and the Google Play Store. For iPhone users, there are other .kdbx-supporting apps, but I haven’t tried any of them, so have a look around and use what suits you. Once you have that done, you will want to install Syncthing on your computer and find a third-party app for your mobile device. On Android, I use an app called BasicSync; there are also options for iOS, but again, I’ve not tried these. Once you’ve got SyncThing, you’ll want to set it up and connect all of your devices together and share a folder between your gadgets. PCWorld has a good tutorial on setting up a synchronized file between your devices using SyncThing. Once you’ve set it up, congrats, you’ll never have to touch that stuff again except for adding or removing devices. I’ll be honest, I didn’t particularly like setting up Syncthing. It didn’t take me a massive amount of time, but I think I had to check online because I found it a bit confusing. That said, I’ve had it running for several weeks now and never need to touch the Syncthing settings, so that’s very nice. I also mentioned a conflicting file. I’m not sure why this is appearing, but the main .kdbx file seems to be updating and syncing just fine. What’s nice is that both KeePassXC and Syncthing are free software, so they won’t just vanish one day; you can take the code and fork the project or use a range of alternative implementations that others have made. It’s also nice that it works over LAN, so even if your ISP is having problems, your passwords will still sync. One area where you will want to be a bit more careful with this setup is if you only have one device. I am OK because I have a computer and two phones, all synced up. If you just have one device, you will probably want to store a backup of your .kdbx file somewhere else. Obviously, you’ll also want to remember your password really well, too. If you get locked out, it's game over. Overall, if you want to take back control of your computing from big tech, taking control of your passwords is an important part of this. You don’t need to immediately clear out your browser’s password manager; try running KeePassXC and the password manager concurrently for a while to see if you run into any problems. If you do try this out, let us know some other creative ways to use Syncthing. I haven’t really come up with a solution about what to do with my bookmarks, for example.
    • If the price was a dollar, someone would complain "Why isn't it free?" If it was free, someone would complain they weren't being paid to play it.
    • That lens of history will burn if you hold it at the right angle... Warn users too late: Shame, Microsoft! That extremely minor update to an obscure Control Panel widget required 2 years of warning. Warn users too early: Shame, Microsoft! We've got better things to do.

    • Microsoft Paint used to be my favorite Windows app as a kid, and it's still pretty good by Usama Jawad I have been using Windows since the early 2000s, when I was around 10 years old or so. I vaguely remember playing around with Windows 98 and Windows 2000, but that may have been on school PCs which had old operating systems installed. My main OS on the home PC, and the one I recall spending most time with, was Windows XP. At that time, I used the home PC to create Word and PowerPoint documents for school, but a lot of the time, I simply used it to play games. My dad would bring game discs which we would try and install on the PC, sometimes unsuccessfully, and sometimes, we would rely on flash games in the browser, like Bubble Trouble on Miniclip. However, the problem with the latter approach was the internet speed. On a good day, our dial-up internet would offer us speeds of 56 kbps, but on most days, it was closer to 33 kbps. This did not facilitate online gaming as I would often have to wait minutes for a game to load or "draw" on the screen, and trying to download pirated games wasn't simple either. I remember getting tired of waiting for online games to load and just downloading simulator games from the Big Fish Games website instead, only to be disappointed after finding out that I was just being given access to trial versions of the title, and I needed to fork out money to pay for the full version. All of this is to say that it wasn't very easy to find entertainment options on the home PC when I was a kid, due to a number of reasons, mostly outside of my control. This situation pushed me towards a rather unconventional ally: Microsoft Paint. Whenever the internet wasn't working as good as I expected, I would simply spin up Paint and draw complete rubbish on the canvas. Of course, that wasn't always the intention, but it usually happened when I messed up drawing a straight line or something, and then I would give up on that particular piece and simply draw a random collection of objects. Microsoft Paint was extremely accessible and easy to use. Even if you weren't an artist, you could quickly understand the tools at your disposal and how to leverage them on a canvas. The absolute breadth on offer ensured that each painting was truly unique, as you could utilize various combinations of tools like the pencil, paint, spray paint, and more to truly personalize your creation. Since I wasn't particularly good at drawing both on digital screen or a physical screen, I remember that my main style of art would be to insert a bunch of randomly intersecting lines and then fill them with random colors through the paint can. I have trying to replicate that art style in the latest version of Paint below, and as you can see, it's truly Pablo Picasso-esque. The human imagination truly knows no bounds Microsoft Paint kept me occupied for hours and was my best friend when video games on the home PC were inaccessible for one reason or the other. There was no academic or professional reason for which I would need to use Paint, but I still loved using it in my personal time, even if what I created wasn't worth being shown to anyone. It was simply fun. Fast-forward to today, and the situation is mostly the same. Now that I am almost 29 years old, and I still have no reason to use Microsoft Paint in a professional capacity. In fact, I don't even use it in a personal capacity, except to dabble with it from time to time, just to see if core functionalities are still intact. And I'm happy to say that I think Microsoft Paint still offers the same accessibility and inviting experience that it did to me a couple of decades ago, even though its UX has been refreshed and it's been integrated with Copilot features. Interestingly, things could have been a lot different, had Microsoft had its way. Microsoft Paint was marked for deprecation with the Windows 10 Fall Creators Update in 2017, and even began displaying a product retirement alert, urging customers to shift to Paint 3D instead. Fortunately, after consumer backlash, Microsoft reversed course on this decision, and Paint continues to be a native app inside Windows installations that can also be updated quite frequently through the Microsoft Store. Instead, Paint 3D ended up on the chopping block, which is for the better, I think. I have intermittently played around with Microsoft's refreshed Paint experience in the past few years, and I do think it has received worthwhile upgrades. the UI and the UX has been modernized while retaining core functionality, and the app is still fairly easy to use. It doesn't meet any of my use-cases, but I've never really had any use-cases ever, as described previously. Of course, the elephant in the room is the Copilot integration. Personally, I believe that this is one place where Copilot does make sense, environmental concerns aside. I know that a lot of creatives use AI to generate images, and while some may be using professional alternatives, Paint still offers a decent casual experience, with the power of Copilot. Of course, you do need to have a valid Microsoft 365 Copilot license and available credits to use it, but even if you don't, you still get the big Copilot button in the toolbar, unfortunately. All in all, I am glad that Microsoft Paint continues to be a native feature in Windows 11, and a piece of software that has evolved to meet modern needs without cutting off its own roots. It's just an iconic piece of Windows history that was an essential part of my childhood, and while I don't use it anymore, I'm just glad it is still there.
