If vanadium was like a typical chromium browser, I'd still be burning battery. Vanadium is core to Graphene. It is part of webview which is how basically everything works on the device. Someone explained it to me a few years ago, bit I don't totally understand it. I got bad/typical battery life with a 4a and Firefox derivatives for privacy. It was only after I went to vanadium for everything that my battery life went much longer. Like, right now, I've had a bad health day so on my phone more than normal. It is 10:30 pm and I'm at 55% battery. I've watched around 2 hours of YT, played a few dozen rounds of Gauguin, read a few articles and spent a few hours on Lemmy today.

I default to 480p video with webp and I turn off my router's 2.4G and only use 5G. I'm also using auto reboot stuff in Graphene to clear anything in persistent memory and the same in the router. Those also help with battery.

It isn't just the network, and it isn't just Graphene, but it all plays a part.

The way Graphene does root is what actually sold me. Having root generally available on any android device is insane. Tethering root to USB debug is a great solution when combined with the TPM, OTA, and the Auth app.

I don't commute or ride in traffic any more. I have no margin left. My last hit was in early 2014. Bosch drive e-bikes became retail available around the summer of 2013 in south Orange County California, and were not present in substantial numbers until around 2018.

Now, drivers are much more aware of faster bikes in bike lanes. In all the crashes I was in between 2009 and 2014, I was even faster than most e-bikes are now, but I was an extreme anomaly in that respect. Bikes were not super rare on the road, but racers on general roads commuting have always been rare. Like if you're going to train, it is not on the surface streets. Several of my crashes were from a time when I rode a 33 mile route each way to and from work 5-6 days a week. I'm one of the most hardcore all-weather, nothing-stops-me roadies you'll ever meet. Like I ride home with broken bones just to say I made it.

Anyways, I'm on a tangent. On the road, around unpredictable drivers, my rather rare speed led to crashes. I had hundreds, if not thousands, of near misses. I had 6 crashes from cars in 150k miles of riding and have had none since. I am at around 250k now. I'm a lot slower by average speed, and I never ride around traffic like I did back then. Both of my bad crashes were from someone making an illegal u-turn. That is the one event where intuition lies and there is nothing a person can do to escape.

It looks exactly like all of the hundreds of times when someone has pulled out in front of you and cut you off. So you instinctively swerve, but as you do so, the car keeps going and closes the escape route faster than the brain will reprocess the inputs.

It is no different for a driver in a passing car. The worst scenario is being on a bike, right behind that passing car, and being as fast as the cars on a slight down hill when someone pulls a sudden u-turn into a passing SUV. That is what got me. The car in front of me was doing 35mph and never braked. It was a Jeep Grand Cherokee t-boning a Mitsubishi Montero. I know all about it from court stuff, but I went black retroactively to the moment I merged behind the Jeep until I was in the ICU 3 hours later. I braked according to witnesses, but my Garmin GPS computer showed I made contact at 29.7mph. I was folded in half backwards.

All but one of my crashes were like that, where it was absolutely due to errors of dumb drivers. All were also in the most southern parts of Orange County CA, in smaller areas with poor infrastructure. At the time, I rode mostly in more developed areas of city with better infrastructure and those are generally much safer. I had a lot of close calls in those areas but they are usually avoidable within the space available, unlike people that get lost or are dopey on the fringes where there is no proper infrastructure.

The way root is managed and the security of OTA updates along with the demonstrated knowledge of how Android users groups and SELinux effectively work are far superior to anything else I have seen in any ROM that I have run previously. Most others were little more than novel demonstrations of CVE vulnerability exploits and setups intended for oddball extra use cases and not a primary device in their implementation. Graphene is a legitimate ongoing secured solution well worth supporting. The TPM chip is a huge deal here.

[-] j4k3@lemmy.world 3 points 4 days ago

My 6a does.

The trick is that, on my second Graphene phone I put it on Graphene from the start, never installed or used anything else on the device or even allowed it access to the internet. I also gave into the advice to try to avoid external apps whenever possible. I have a few odds and ends installed but not nearly as many as people have been trained to do for normalized stalkerware exploitation. Signal is my only continuous battery draining background app. I do everything in the vanadium browser like with Lemmy. The only other regular internet connected app is Pipe pipe and I do not use any scheduled background stuff with it.

I only allow WiFi data most of the time and my network is exclusive to my devices with a whitelist firewall on a dedicated device. Cookies and trackers are not just blocked by Ad Block on my network. I'm blocking tons of extra background nonsense everywhere on the internet, so these things never reach my devices.

For instance every time you see the social network icons at the bottom of a webpage, those are embedded links to those services hosting those images. You are actually visiting all of those places and retrieving those tiny images while giving them your fingerprinting information. They know every page you visited and how long it took between pages. All of that is tracked. Most pages try to use google static for fonts on their pages, which is doing the exact same thing. But, when the google static server is blocked the page will default to your system font and there is not any real difference unless they are using really odd special characters like rare symbols or super rare emojis in Unicode. Like I have almost all languages to the point of Egyptian hieroglyphs and cuneiform, so I never see bad characters in practice.

When I visit a website, I am only visiting the sever I whitelisted. It is a pain in the ass to manually whitelist everything I want to visit, but I have been doing it for years after some sketchy stuff happened while I was building breadboard computer stuff and downloading vintage hardware PDF datasheets from 3rd party sources. Anything I download is unable to dial out to any address unless it is whitelisted on my network. I can also write code that is sketchy and I don't need to worry about it doing dumb stuff like nmap'ing the whole internet. Or like now playing with offline AI running on my hardware, I do not need to worry about a model agent doing something dumb, or nefarious stuff that may be hidden and undetectable in a fine tuned model.

Anyways, I don't do it for the battery life, but the battery life is a bonus side effect. I also do not shop or make purchases on this device or network. This is for social, YT, and news stuff only. These are partitioned so I can take absolute control over my spending habits and break any direct link between these areas and purchase tracking. This partition stopped me from making frivolous purchases.

Graphene is just one part of my strategy, but an important one. Graphene does much to limit the background junk on Android's zygote app preloading system that only really exists for stalkerware junk. It was supposed to be for faster app loading but the difference in time is far less than the speed of human persistence of vision.

Tit for tat is an English saying meaning "equivalent retaliation". It is an alteration of tip for tap "blow for blow", first recorded in 1558.

Tit-for-tat has been very successfully used as a strategy for the iterated prisoner's dilemma. The strategy was first introduced by Anatol Rapoport in Robert Axelrod's two tournaments, held around 1980. Notably, it was (on both occasions) both the simplest strategy and the most successful in direct competition. Few have extended the game theoretical approach to other applications such as finance. In that context the tit for tat strategy was shown to be associated to the trend following strategy.

https://en.wikipedia.org/wiki/Tit_for_tat


I'm abstracting and expanding how I interact and analyse other people in this thought. Like if a person, business, or boss takes actions that are not in line with Tit 4 Tat, I expect them to be unsuccessful and counterproductive in the long term. It is an implied strike on their part and therefore requires an equivocal response or else I am not maintaining my own requirements for success under said strategy.

Anyways, it was an actual shower thought

It is not about that. The pixel has a TPM chip (Trusted Protection Module). This is similar to how secure boot works in desktop computers. It is a special external chip that has a secret internal cryptographic key that can never be accessed by anyone. This chip can be used to create secured communications between devices. This is how it is possible to do over the air updates securely and how the device's security can be checked with a special app and an external device like an old Graphene phone. All files on the device can be hashed with the secret key to determine of they have been changed. Other phones do not include a TPM chip and this is the primary reason they cannot be supported directly by Graphene.

Get off the train. A Pixel setup with Graphene OS never has such nonsense features. I even fully control my own notifications. A 2 year old device still has 2 days of battery life with lots of use, and I have no bloatware at all. It isn't like some difficult techie thing either. Updates are secure, automatic, and over the air.

I've been hit by 7 cars in 6 crashes. Three caused only a few scratches and bruises, one made a wheel taco, one left the bike frame in two pieces, and the last cost me 8.5 of 9 lives to fight and total two SUVs. I can't say that I recommend any, but I will say definitely don't fight two at once

I don't care about the kids under 30. The funnier the better, and the older you are the more I want to know: what would you like to be when you grow up?
Achievable goals fall short of true potential.

Or is there maybe a way to set the pager for all help related queries to some command? I'm using bat and would like to pipe all --help through | bat --language=help by default for the syntax highlighting and colored output... Or if you know a lower effort way to color the output of --help let me know.

I have a small hard drive that is making a constant high pitched sound that is typical of the drive, and not very noticeable to the average person, but I have pain induced noise sensitivity. I am curious about how to calculate damping potential. As an initial guestimate, the frequency is very near to my maximum audible range and likely around 12kHz-16kHz. It is a little higher than the switch mode power supplies that I can also hear if it is dead silent in the room, although the drive is a higher amplitude. Addressing the noise with a solution is probably beyond the scope of anything I would actually do, but knowing how to solve it is far more interesting to me. (ELI15 )

Is it super standardised, like where all 30 or 40 pin LVDS connections are the same, as in pin and voltage compatible?

Are there hardware peripherals in a microcontroller that just drive LVDS like how UART, SPI, CAN, etc. work? Or is it a messy complicated thing with display specific power supply voltages, and unique power management requirements, baud rates and such?

I can find lots of old style monitor to HDMI or VGA conversions for an old laptop screen based on display model number. But what I am looking for is a USB-C/USB-3 to LVDS converter board small enough to fit into an old apple laptop top shell and act as a second monitor with all power and functionality controlled through the USB interface. I have the fab skills. If there is a simple chip that does USB-C PD/display to LVDS, I'll toss it in KiCAD and etch it myself if I can get the chip. In my past experience with small displays for hobby microcontrollers, they were anything but standard in most cases. I have never messed with the larger stuff though. It appears like most of the old style VGA/HDMI converter boards are mostly sold with the same hardware/board with the proper LVDS connector installed.

I can take care of the backlight driver part. I'm mostly concerned with what is going on with LVDS in practice. Anyone familiar with the subject on Lemmy?
