Well private gun sale laws vary from state to state. For instance, in Oregon private transfers of firearms are perfectly legal without background checks or going through FFL dealers. So anyone can side-step a background check in a state l

Please excuse my ignorance on this matter, but why are people so concerned about "untraceable" guns (i.e. guns without serial numbers)? IF a gun is used in a crime, how important is it that there's a serial number stamped on the receiver?

I'd upgrade to the Paperwhite just for the built-in light. I backpack a lot, and reading my Kindle with a headlamp is really annoying...

That's a made-to-measure (MTM) suit, which is a completely different animal than a bespoke. I get MTM suits for myself, but I have a cousin that buys bespoke. They're so nice...

So if you wanted to see the actual salary of a particular coworker, all you would have to do is create a pool, enter in 3 bogus salaires yourself, and give the link to the other person?

Asking the world to change/ boiling the ocean... Plenty of people get drunk without sticking their hands up women's skirts. The "logical conclusion" is not to remove the women from the equation.

It's pretty clear that the issue at hand is harassment, not merely being hit on.

What you're saying is this is how men behave and women should either put up with it and stop complaining, or stay home?

One site, I think the LA Times, would show your the entire article but then redirect you to their pay page after a few seconds. I just turned off javascript and it solved that issue...

The article does mention Etsy. There's even a link to a research report on the workings of IV.

More megapixels isn't necessarily better. The sensor was probably chosen for a specific reason, one reason may be that the sensor was matched to the optics (lenses) they decided to use...

It's nice to see a company and law firm that not only acknowledges its fans, but doesn't treat them like criminals.

People don't die after only 2 days without food. The title is misleading and the article is full of speculation.

It is, the problem is "trained professionals in the field" don't review patent applications. Having a patent attorney file the application all but ensures that just about anything is patentable (provided you're willing to pay the legal fee

Yes, given that C major is the most popular key, it follows that C, F, and G are the most popular chords. That's called a I-IV-V chord progression, and is the basis for most blues, which rock (and subsequently pop) evolved out of. Oh, and

The title is fine, I had no trouble understanding it. The ambiguity of "married" did not lead me to believe that Mark acted as officiant in a wedding ceremony, nor did the open-ended past tense of of the term lead me to believe that Mark w

Definitely. Take care of it and it'll last, probably got mine 7 years ago now. If it were to break on me today I'd get another one.

I have a Herman Miller Aeron with PostureFit. I used to sit on one of my wooden kitchen table chairs all the time and always had lower back pain. A good chair is expensive but well worth the cost.

You wouldn't even notice any flickering at a PWM frequency of 120 Hz. Linear (resistive) dimming is just not done anymore. Just about all lighting fixtures these days dim by either PWM or chopping the AC signal.

The LEDs are typically blue with a phosphor that is energized by the LED light. It's the phosphor layer that starts to glow and produce the white light. If you "paint" a surface a particular color to alter the light transmitted through it,

Voltage fluctuations don't matter since they're driven by a switching constant current supply. The voltage drop across one high brightness LED is only a few volts.

Generating a PWM signal based on a particular LED's characteristics is similar to designing the gain of an amplifier circuit around a particular BJT's beta. It's just not done. That's also the whole reason behind controlling LED brightnes

It would be more like at least 10x the PWM frequency, if you wanted to see a square waveform.
