Reddit Moderator Outs Reddit Admins

Khyber (864651) writes "While the censorship is strong over at Reddit, details from a (former) moderator of one of the largest subreddits on the site have been leaked in the form of an an audio recording of a Skype conversation between an unidentified journalist and the moderator himself. User posts are being deleted rapidly from Reddit over in the /r/gaming subreddit, users are being shadowbanned, or hard-banned. (I've had my account dropped.) Really interesting parts of the 50-minute long audio sit around ~10:30 and ~26 minute marks, where the moderator details threats made against him and other moderators, and also a bit near the end regarding their censorship/spam control tools, and how anyone can effectively be banned for any made up reason, commonly-used ones being vote manipulation, brigading, and alt account creation. There is also talk about how subreddits for encryption get monitored much more closely and censored much more often than larger subreddits, such as /r/gaming.

As someone I know has put it, "...given that Reddit says that it views itself as a government for a new type of community, this is disturbing.""

Toyota Backs Away From DesktopNexus

Khyber Khyber writes  |  more than 6 years ago

Khyber writes "Slashdot recently covered the ongoing potential litigation against DesktopNexus, which included the demand that all images containing a Toyota, Scion, or Lexus were to be taken offline. Being an owner of one of those images, I immediately fired a very sternly-worded email (with help from a lawyer.) Toyota has capitulated, as noted here in their response to me:

"Thank you for contacting Toyota with your comments and concerns regarding the use of vehicle images. The letter asking the DesktopNexus site to remove all images featuring a Toyota, Scion or Lexus vehicle was the result of miscommunication at Toyota, which we regret.

Copyright law protects the creative work product of artists, photographers, and other creators. Toyota respects these rights, including those of photographers who work with Toyota. Toyota purchases the rights to the images it posts on its sites, and welcomes public use of those images where we have the rights to give. However, this permission is limited to editorial or personal use, not commercial use, such as advertising any products or services. That's because the photographers — not Toyota — retain the rights to any commercial use, and we cannot give permission to use those images for that purpose. In response the concerns raised by DesktopNexus, Toyota is working with photographers to determine what images may be used for noncommercial purposes, and what we can do to provide broader access. We hope you will understand and appreciate the legal constraints we face.

Toyota also welcomes interested members of the public to use their own images or photography of Toyota's vehicles, and we confirm that we have no objection to this use.""

With every program I install, I'm going to take another snapshot, burn to DVD, and repeat the process until I have recreated every step taken to get to my current system state (all programs installed on a separate hard drive, all registry entries etc on the OS drive, with only snapshots of the OS drive being recorded.)

Kinda reminiscent of the wooden-knob potentiometer that costs $400. Anyone have any idea how companies manage to get away with this?"

New scanning technique key to better processors

Khyber Khyber writes  |  more than 6 years ago

Khyber writes "Deformations in silicon are responsible for high electron mobility, which gives us better efficiency and higher speeds while reducing energy consumption. Until recently, chip manufacturers have only been simulating deformations in the silicon caused by stress on a nano-scale in order to get increases in ability. That will all change with a technology based upon electron holography. This method has much finer scanning resolution, and can scan thicker wafers of silicon, thus ensuring accurate measurements of stress at most any level of chip design. This greater understanding will lead to new silicon wafer designs and also greater yield potentials."

Lighting LEDs directly from AC easily achieved

Khyber Khyber writes  |  about a year ago

I figured out a simple way to make DC-operated LEDs work from AC. Most people suggest using a bridge rectifier. Why not make the LEDs the rectifier itself?

So I salvaged some LEDs from old damaged panels, and used them to create a rectifier. However, I used a 12VAC 200mA max wall wart, not 120VAC from the wall (I did not want to wire up four 120V strings of LEDs plus resistors and a smoothing cap for flicker reduction) so the circuit could be made incredibly basic. Essentially, the LEDs themselves acting as a rectifier eat up all of the voltage. Reverse voltage breakdown is not a problem, as voltage seems to add both ways. 12V total Vf for the LEDs, but as each LED has Vr of -5V, the total Vr is -20V. Can't overpower that with -12V. I've had my prototype running an hour straight on a heat sink, and so far not a single issue.

Too bad this is too obvious and simple to be patented. But have fun with it!

The flicker is certainly there, but for horticultural applications, as long as the photon output is acceptable, it will work. This should simplify LED design drastically.

Have video and have some some neat pictures.

Google Took My Money

I've been using Google Helpouts for a week, now. I haven't done much, only two clients, but I was supposed to be paid. I was under the impression that I didn't need a bank account to use Google Wallet. The wording on their site is 'Recommended.'

Well, my customers have had money taken from them, and not delivered to me. In order to get this money, I *HAVE* to have a bank account because I am now a service provider. None of this is mentioned when I went to update and verify my Google Wallet information. I've been on the phone with Google, they've been unable to do anything, so they say. Google, acting as the middleman, has essentially taken my money and says they can't do anything about it until I get a bank account. That's not possible until I correct an outstanding balance. I was hoping to use Google Wallet to be able to save up that money and then pay off the balance then and there. Nope.

So I've given out services and Google essentially refuses to pay me what I'm owed until I go through a third party.

Help me spread awareness, if you can, by giving me a +1 at https://plus.google.com/110351126148578351575/posts/h7QmWoRrtYA

Going to a Low Tech Hobby

Khyber Khyber writes  |  about a year ago

A few days ago, I went for a walk down the local riverbed. To my surprise, I wandered upon a large cluster of grape vine, bearing wild grapes, tons of tiny ones.

Well, they're about 70/30 seed/fruit. Go figure. A little sample, and the flavor was a mix of tart and sweet. These would make a good wine, I figured.

I decided I'd go ahead and make a slightly more refined version of what the Romans and Greeks might have had. After the grapes were washed with a light bleach/water solution, rinsed thoroughly, and mashed, I had about 1.5 gallons of juice, to which another 1.25 gallons of water was added, plus 3 pounds of raw cane sugar, and 2 teaspoons of proofed bread yeast. All of this was put into a 3 gallon carboy with a rubber stopper and typical airlock. Right now, I'm getting a bubble roughly every 2 seconds from the airlock.

I'm expecting a wine with not a whole lot of alcohol, and a bit of sediment. There's not much point in doing a bunch of fermentations and filtrations on my first go-around. The smell right now is very light and quite pleasant. Almost like a perfected Boones Farm wine.

Have some HD video.

This should be ready in about 4 weeks, I'm not expecting a huge return on alcohol content given the yeast is past the best by date

Review: SinkPAD Direct Thermal Pathway PCB

Khyber Khyber writes  |  about a year and a half ago

I've spent the last month testing and demolishing a bunch of new-design thermal PCBs from SinkPAD, and have come to the conclusion that this is a solid solution versus traditional dielectric PCBs commonly used for mounting LEDs. There are many pros, and a few cons, and I will address these in my review of their product, written below.

We will start with the good stuff first, the Pros. The SinkPAD Direct Thermal Pathway PCB is made from solid aluminum or copper (as of the time of this writing I had yet to test any copper PCB), so it's very good at thermal transfer. This helps make it easy to solder; versus a traditional dielectric board, the solder took to the SinkPAD in roughly half the time. This also comes in handy for reflow work and rework, as mounting and un-mounting an LED from the board is quick thanks to the PCB being constructed out of high-conductivity aluminum and copper. Repairing any mistakes takes minimal time and effort, a must for any prototype designer or hobbyist. The solder resist is also very solid, during my reflow cycling test I never once saw a solder bridge form, nor had any shorts. The same solder resist is quite durable against thermal shock as well. I torched it until it was smoking and crackling, near-black, and with no problems I was able to mount an LED to it and light it right up, and the remainder of the pad transferred heat exactly as it should. This durability is exactly what the military and police forces could use for LED-assisted weapons solutions, such as barrel or grip-mounted lights, or IR night-vision equipment. The aluminum boards are light-weight and stiff, very difficult to bend, even with a pair of clamps and pliers and my full weight applied.

Now for the cons. Due to how the thermal pathway is manufactured, there's an indentation on the back of the board. This means you need to use more thermal paste/epoxy, and you need to be more careful not to introduce air bubbles and gaps. On the aluminum boards, there is no solder pad on the back side, which would help greatly since solders tend to be more conductive than thermal pastes and adhesives. The copper board likely wouldn't need it, since copper is easy to solder. Speaking of copper, there are a distinct lack of copper options for many of their PCB choices. While this is understandable (many of these LEDs simply don't need it) the ability to have broader choice in materials would be nice. My final bad note is the difference between prototype boards I have versus some of the production boards. An older X-Lamp XR-E board had four screw holes for improved mounting, and they were placed so that most screws that could fit those holes would not have the heads short out on the contact pads. These holes are nonexistent on the star and disc boards. The star have their electrical contact points too close to the indents at the outside to allow screws to be attached there, but the circular boards look like they might have a better chance.

Overall, this is a solid piece of thermal management tech for LEDs. The ease of use and durability should appeal to a wide variety of LED consumers, from hobbyists, designers, and engineers to police, military, and even more groups of people and industries. Most of the cons are personal nitpicks and aren't exactly game-breaking important, and the pros certainly outweigh any con I've been able to notice. Highly recommended.

SinkPAD & CREE, Together At Last!

Anyways, I just shot a little run of the MK-R, both of them, driven at 18w each. Note how they obliterate the Cree XR-E to the left, driven at 1.2-1.3w or so (3.7V rated Vf @ 350mA.)

Night Test of the MK-R

Khyber Khyber writes  |  about 2 years ago

Finally got around to doing a night test of the MK-R.

I went out onto my patio, and put it right beside my 100w incan that typically lights the porch.

And here's the result. As you can see, absolutely no contest. Fluoro equivalent to 100w incan is a ~26w bulb, so we're looking at around 25% the power consumption of an equivalent CFL (LED driven at 6w) and way, way more light.

Still unable to drive full power. SinkPad mistakenly sent me XM-L boards, not MK-R.

Checking Out The New Cree MK-R LED

Khyber Khyber writes  |  about 2 years ago

I managed to get some engineering samples of the Cree MKR LED announced on /. a couple weeks or so back.

Needless to say, I was thoroughly impressed. I ran 12V @ 200mA, 500mA, and 1250mA. You know how us geeks/nerds say do not look into laser with remaining eye? You don't HAVE any eyes left with the new MK-R, even at a measly 200mA of direct current at 12V. At 1250 mA, I only needed half a second before the diode packaging began to melt the green PCB, the heatsink was absolutely ineffective. Be prepared to use metal SMD-mount boards for these diodes, because that cheap green board used for most SMD LEDs simply will not cut it. Pushing 15w in a 7mm x 7mm package, you need serious heat dissipation capabilities. Also, DO NOT HOLD THE DIODE WHEN DRIVING AT 200mA! You will blister yourself.

I no longer have my light meter, as I would use that to check flux levels and lumen levels, but needless to say, you drop a quad of very-efficient nearly 4-watt diodes into a single tight array like this, and the world is going to light up before your eyes. I would love to see one of these in a Mag-Lite. At 200mA, 500mA, and 1250mA, you would have all the light you need. Remember that commercial where the kids with the flashlight are using new Energizer batteries and it looks like they're suddenly using a 1,000,000 candlepower light? It's even better than that.

Just one of these would light up my entire 15' x 24' living room, quite possibly more, with wonderful light levels. I could see this sitting in the center of my ceiling. Two bedrooms, two bathrooms, living room, kitchen, dining room. Seven rooms, 105w operating power with all in operation. I could leave my whole home lit up for the same cost of a single 100w incandescent light bulb, which barely lights one room. Oh wait, I forgot the porch and patio. Make that 135w operating power. And in reality, even at 500mA drive current, I think that's more than enough light for an area roughly 25' x 25'. Still beating the pants off of equivalent incandescent or fluorescent. It's the end of them, and I already have the belief that these will truly smash HID systems.

I want single-color versions of these. Cree, if you're reading/listening, you have technology in your hands right now to take over an entire segment of the optoelectronic market. You dropped out of said market (and a couple of others) when you quit making 660nm diodes, and you could really take this class of diode to great heights if you could specialize single-wavelength versions of this.

Gearheads!!!!!!

So I just popped 175K on my '98 Taurus. I'm quite pleased with this vehicle. The AC is dead, and I've only had to replace the transmission once at 125K, when the planetary gear chewed itself to shit going to Washington back in 2008.

Any other gearheads reading this journal? What're you driving, and what're you pushing mileage-wise?

Regarding the Last.fm/Skype debacle

Khyber Khyber writes  |  more than 2 years ago

Took me a while, but after more careful digging, I've figured out what is happening. Last.fm is indeed lying. They are not listening to your media players. They are listening to your sound card output. Disabling sounds in Skype will disable every Skype event log except for two - updates to mood/music playing, and any time you make a skype call. Those to events trigger Last.fm logging. In the log, there's no real identifying information. What can be gleaned, though, is how long you made that call.

"If you choose to download the Last.fm software, it will monitor all the music you listen to on your computer (even if you are not online). It will then send this information to Last.fm via Audioscrobbler. This information will then be integrated into Last.fm to enhance the depth of your record collection and the accuracy of your profile.

The Last.fm software cannot and will not collect and transfer any other information from your computer other than as described above."

That is a flat-out LIE. And you're not even told about the integration with Skype when you install Last.fm's Audioscrobbler. You have to find out yourself by looking through log files, or go back to an obscure 2006 Skype Blog post.
