Is the App Store Broken?

Hadlock Re:MORE STATS!!! (160 comments)

Yes, this is idea. The google play store is completely useless for finding top notch apps. As with the PC market, there's usually 2-3 applications that have all the features and aren't buggy and don't have a terrible user interface, and then 1-2 open source options that are very similar, and then 10,000 one-off single feature applets which are mostly useless and ancient.
 
I don't even use the google play store search function. I just google for lists of top versions of the type of app I need (with this year's year in the search results), then go download/buy that one and hope it stays updated.
 
I used to wonder why people use brand names when product names are so important. This is why. Complete chaos. In 10-15 years there will probably be an umbrella of 20-30 companies that offer suites of good programs that all work together well. Right now I'm going to avoid a new program by a new developer unless it does proper magic like Word Lens (which is now owned by Google), and just stick with curated lists on %RandomAndroidApprRviewSite%.

Quiet Cooling With a Copper Foam Heatsink

Hadlock Re:Dust (147 comments)

DUST
 
So you've come up with the ultimate heat sink, but now you have to run it in a positive pressure ventilation clean room.
 
Might as well just stick the PC in the closet and run an HDMI over Ethernet to your desk and use wireless mouse/keyboard. Now that we're not forced to use a maximum of 9' VGA cable, and nobody uses physical media anymore, there's zero reason not to stick the PC somewhere else and run an extra CAT-6 drop for the video (HDMI over Ethernet needs 2x1gbps)

The Army Is 3D Printing Warheads

Hadlock Re:GPLv4 - the good public license? (140 comments)

And in the 20th century Spain was mostly a ghetto and the rest of the Spanish speaking countries, banana republics were mainly dealing with internal conflict (or US intervention *cough* Guatemala *cough*; all of South America has been peaceful since the Bolivar republic split over 100 years ago; China hasn't had a military victory of note in the last 120 years, which is why I explicitly said 20th century. Thanks for the irrelevant 400-year history lesson, though.

SpaceX Releases Video of Falcon Rocket's Splashdown

Hadlock Re:I wonder how long it would've taken NASA? (49 comments)

It's really hard to do this kind of landing burn (nicknamed 'suicide burn' as you run out of fuel as the landing feet touch the ground at 0 velocity, and miscalculation and splat or a nice bounce (elon called it the hover slam)) with a solid rocket booster, which we keep buying/making to prop up the ICBM industry with civilian dollars. The shuttle ended up with SRBs instead of L(iquid)RBs purely due to political reasons.
 
Actually, for the Saturn V, blueprint drawings do exist made by NASA of a cockpit on the side of the main booster tank with glider wings, to take it the 300 miles back to a safe landing site. Obviously that complication got scrapped in the mad rush to get to the moon in a decade.

Google Offers a Million Bucks For a Better Inverter

Hadlock Re:Why? (260 comments)

The wiki page they link to has a photo of a converter that converts solar DC to electric grid AC. I'm not sure if they're looking to do residential solar with the inverter on the back side of the panel group or use this in a datacenter...

Slashdot Asks: Do You Want a Smart Watch?

Hadlock Re:Yes (381 comments)

I've yet to see the "killer app" for the Pebble smartwatch. Neither could they, which is probably why they open-sourced the SDK. If they had a killer app they would have been purchased (or emulated) by Apple/Microsoft/Google et all already.

Intel Offering 3-D Printed Robot Kits

Hadlock Re:At those prices? (26 comments)

Have you looked at how much robotics parts cost? A cheap servo is $12, an acceptable servo costs $45, and good servos you might use with surgical precision start at $95. High torque high precision motors a human sized model start in the $450 range and go up from there.
 
Six range of motion arms (let alone three digits per finger) means 12 servos for just the arms. It's no wonder people are looking at pneumatics, hydraulics etc for high torque high precision "digitla muscles". Robotics is expensive. And when you wire a servo wrong at 4 in the morning because you've been working too long you end up replacing these things at a fast rate (Ask me how I know). Just getting in to a 5 degree of motion laser cut wood arm, starting the hobby from scratch, cost me about $600. And that's with the $12-20 level servos.

The Bursting Social Media Advertising Bubble

Hadlock Re:Tuning it out? (254 comments)

Social media works great for things I will talk my friends about movies, politics, and occasionally global sports like the world cup or Olympics. Since I don't watch TV I couldn't tell you what's playing right now, especially since most movies are reboots or sequels which really blend together unless you've seen the trailers a few times. I did end up buying a ticket to the Lego movie due to an ad on Facebook. After almost all of my friends had been talking about it for weeks. Ads for dishwashing soap, soda, pizza etc don't even register for me mentally online.

Teaching College Is No Longer a Middle Class Job

Hadlock Re:I just want to know (538 comments)

Citation needed on point 1; everything I've read says that football produces about $15 for every $1 invested in the program. This probably isn't true for other sports, but College Football is Big Business in the south for Universities.

Pixar To Give Away 3D RenderMan Software

Hadlock Re:Wow... this is actually pretty big (147 comments)

Does blender have a greater, lesser or parity feature set compared to RenderMan? That's an important question for the casual user. I use blender quite a bit for 3D modeling for Kerbal Space Program, but if Render Man is better, and has the features I need, then I might look at their free edition. I use blender because it's free and do about 20 hours a year of 3D modeling a year for hobbyist purposes.

What happens to Blender? Will RenderMan have the ability to replace Blender as an all-in-one 3D modeling/sculpting/rigging/animation/rendering engine, or is RenderMan only an animation/rendering engine?

stillborn

Hadlock Hadlock writes  |  more than 8 years ago

i thought i'd go ahead and write one more article in here, since the other article is so blah and that's what comes up when you click on my journal. this slashdot journal system really was a stillborn project; i'm not sure if they keep it around because cmdrtaco and friends still use this thing, or if there's actually people who use this on a regular basis. either way, this is the first post in four years or so from me; i was using lj before, and will continue to do so despite compeitors like myspace. here's to another 4 years of not posting in this.

LC case mods....

Hadlock Hadlock writes  |  more than 12 years ago

Well fuck this. I'm getting my fucking work done; I'm just bored and relaxing. I would have this fucking shit done by now if I hadn't goddamned fucked up with the whochamacalit. Chapter 7 instead of chapter 5. Grrrr. Spring break in like, 3 days. Sigh. Umm what else to talk about? After looking at case designs for my mac, I looked at the case for my mac, and specifically noticed that the fan on the bottom sucks in A LOT of freaking air. Wow. So that limits my positioning of the fan. I guess I could mount the fan as an exhaust fan pressed directly up to the power supply, as the only thing I really need to worry about is the powersupply, it gets fairly warm without any decent airflow. Warm isn't really a problem; but I want things as cool as possible. Maybe mount a heatsink or 9 on it? Hmmmmmmm. SCSI drive is just going to run hot regardless. Put it near the convection vent on the bottom, and let the cool drafts passively cool it. I don't really have to worry much about the motherboard, as it doesn't create enough heat to warrant active cooling. If it's not warm enough for apple engineers, it's not warm enough for me. Hell, it's $5 hardware. Crazy that it used to be worth $1200. Crazy. I really need to go get that $5 LC II from allen, and build a mockup of what I'm going to need to do for my final case design. At least if I fry that hardware, I still have a backup or 2. The only things I'm worried about are my HD and NIC card; the rest are pretty easy to get as salvage. Well I have an extra hard drive, so I guess all I need to do is buy a spare NIC card and I'm set. Some foam on the lid and back would probably provide decent sound insulation. In the final model made of aluminum and plexiglass, I could probably make some metal mounts and epoxy them to the inside of the aluminum cover, and then have the hard drive pressed against the lid. I'd need a slightly longer SCSI cable, so I don't tear up the motherboard when I open the lid? Internal lighting (blue neon light) would be bad-ass. Need to work on a way to run power cables up to the case....hmm. possibly that external SCSI CD rom drive's powersupply; that could potentially power both a second HD and/or a neon light. I could power it off of the LC's powersupply, but that would really just be overtaxing the power supply and a dumb design flaw on my point. I guess the dealy-o (yo), would be be to have a tube of some sort carry the power cable for the LC, 12 DC wires running up from a wall wart, and the RJ45 connection all inside a black or white, possibly light grey flexible tube. I think you can buy this at places like home depot. One idea I've been throwing around recently is that if I'm going to light this case internally, a frosted, or textured type of plexiglass, instead of the really hella clear plexiglass that shows srcapes and scratches really easily. I might have to sand blast my own? Hmm another idea- make the case out of clear plexiglass, and then tape down a cardboard picture of an apple, and sandblast the whole thing, removing the cardboard to give a relief of a clear apple. Kinda cool, but not exactly what I'm looking for. What I want is the front of the server case to look like the back of my powerbook - glowing white apple surrounded by brushed metal. I'd have to get the metal laser cut and then stick in some opaque plastic to be backlit. It'd be tight.

On an unrelated note, you could potentially cool a system with chlorine or argon gas, as they're element numbers 17 and 18 on the periodic chart. Instead of nitrogen, #8, with an atomic weight of 14; while chlorine and argon have weights of 34 and 39.8, respectively. Nitrogen makes up something like what? 72% of the air? 78% according to my envy sys book (I knew it would come in handy for SOMETHING. Sigh. CO2 and O2/3 make up something like 21% of the remainder. Nitrogen weighs the most, at 14, oxygen 12 and carbon not far behind. By effectively changing the density of the air, in theroy, that should increase the heat absorbtion factor. Of course, you can't just buy argon, BUT, you can buy an argon something something canister for your inert gas wielder. My plan would be to create a closed system with some sort of radiator picking up the majority of the heat in a closed system. It seems damn complex though; still requiring a water pump - the only advantage is that you don't have to worry about condensation on the processor, as you'd flush out 95% of the o2/h20.

perfume

Hadlock Hadlock writes  |  more than 12 years ago

i think i finally figured out why i'm constanly coughing when i'm @ program six... it's "summer" now, or one might suspect that from what the girls are wearing on the "not freezing" days and the amount of perfume they wear. that might not be a horribly big problem in a school like PSHS, which is designed to move ALOT of air all the time, but at program six, which is designed for about 60 people, tops, and add another 30, then air problems arise. 15 extra girls wearing perfume can make a HUGE difference in the air quality, and the amount of coughing i do in a day. colonge doesn't help much, either. don't get me wrong, you don't see me coughing when i wear colongne, but you'd cough too if you spilt the bottle on yourself.

infinite number of monkies and a FINITE amount of time...

Hadlock Hadlock writes  |  more than 12 years ago

if you wrote a program that would grab all the words of a specific text into a wordbank database, and then randomly string them together in random sentences, adding punctuation with primitive grammar algorithms.
 
write a program that takes these sentences and strings them together into a screenplay that is a length between x chars long and x sentences (ap strings?) long....say about the length of a shakespeaian play.
 
output this to a .txt file, and write a program that matches the .txt file up against the original document, saving those documents that match up to 75% or higher. would be interesting to read. sounds like a fun project.... or somthing.

english

Hadlock Hadlock writes  |  more than 12 years ago

Blah. English is an old art form, but doesn't exactly mean it is one that should be learned or practiced for more than 2 years in high school. I'd much rather have an option to take two years of art appreciation instead of my last two years of english. As I understand it, we're learning about t the process of how one reads a book, and then goes out and reads other's views and opinions of that book,, and then eventually decide to write their own review of the book, for others to read. From my (probably) skewed view, reading slashdot isn't too horribly different from this. Someone/some company creates a new techonology or does something extremely creative, that took a lot of combined effort and talent, and shows it off to the world on the internet through pictures and words. On slashdot, this is reported, and many people are allowed to read about this wonderous new techonology or obscure and cheap hobby, then read and write their own reviews (post) about it. It's a community that is constantly feeding itself with new content, providing an outlet for idle thought and time. As with writing, only a small given percentage at any one point is idly working on their "next big project", while fewer are producing a finished product to the community each day. This example is almost mirrored on slashdot, which has a community approaching half a million users (although my guess would be that there are only about 100k active users), where 10 to 12 things per day are posted, and usually about a hundred or so comments are given to each post, while many more people simply read the comments, or "Review/critisisms". There are even two users who regularly do literary things in their comments; one writes haikus, while the other has the user name "grammar nazi". You can guess what he does. I'm already actively parparticipating in a large group that critisizes and compliments eachother's works. Why must another established group's thoughts and beliefs be foreced upon me, especially when I have already been exposed to the culture and clearly don't like it? Taking humanaties 1& 2 in my freshman and sophmore years was far more interesting, and covered far more information of interest. Not suprisingly, english was the least covered in depth. Of course, that's offset by the fact that we already have an ingraied and indeph english progam in most, if not all high school programs around the nation. Still, it's good to not be seeing more literature than I want, and the little you do see, is the eccentric kind and might actually be enjoyed at it's face value, without the complex need to dissect and analyze every small bit. Satire is a favorite of mine: easily recognizable and gets I's point across easily.
