niteshifter Re: This is why encryption isn't popular (399 comments)

It's not about the ID itself, that is a 'game token' if you will. The danger lies in how tokens are linked and evaluated by all the other players in the game. Especially if those other player's interests do not consider your interests as worth consideration.

Medical Firm Sues IRS For 4th Amendment Violation In Records Seizure

niteshifter Re:They're just getting a head start on Obamacare. (365 comments)


What you're suggesting is tantamount to the police searching a house for allegedly doing cockfights in the basement and being required to ignore anything else they see while on the premises.

And I've good news for you, sunshine: That's precisely how the doctrine known as Search Incident to Lawful Arrest, aka SILA works. In searches not attached to a potential arrest restrictions still apply. Let's work with your example, cockfighting. A felony in most states. Along the way to the basement the Officer Intrepid spots a roach in an ashtray. Since this ain't Texas, that roach is a misdemeanor offense. Also not covered by the warrant looking for cockfighting evidence. Yes, it will be ignored - for now. They'll be getting busy obtaining another warrant for illicit drugs. Use that time wisely ;)

New OpenWRT Drops Support For Linux 2.4, Low-Mem Devices

niteshifter Re:Brilliant (194 comments)

Yes. I've a pair of Buffalo WZR-HP-AG300H dual band / high power. $90 US via Amazon. I use the 5GHz radios as N dual channel to get a solid 250+ Mbps between backend (where the audio / video servers live) to the "front" (WAN connection and media play 'puter) plus two 2.4 GHz WAPs in mixed mode. "High" power on this means 20 dbm. I had the radios turned down to 8 dbm, but that ended this past Christmas with the explosion in number of 802.11W ** devices around my neighborhood. The router features two choices for firmware built in: Yer basic easy-peasy setup tool or DD-WRT with all the fun stuff.

** 802.11 Whatever. I'm old and tired of alphabet soup.

Windows: Not Doomed Yet

niteshifter Re:nope (737 comments)

I think what Penguinisto is trying to say is that the developer exodus begins with what the dev uses *for themselves* to get the biz owner's Windows servicing taken care of. You are not - in a larger context - correct in saying "you can't rdp without windows": throwing a X screen and keybd across the network is easily done. You are correct in saying that when we do rdp to a win box we're just using our *nix/droid platforms as thin clients.

Now the question is: Why would we want to?

Speaking for me, I just want the damn tool - the computer under my fingers - to just work, with a simple UI/UX that gets out my way and lets me work. Linux/Gnome/CLI and Android/AndFTP/ConnectBot works wonders for me and preserves what little sanity I still possess after nearly four decades worth of computing 'n tech-stuff work.

The odd thing is many of my clients want the same thing from their computing systems: it just works and gets out of the way of the worker so they can, you know, work ;)

Now imagine the conversation they and I will be having over the next few years ...

Turning the Belkin WeMo Into a Deathtrap

niteshifter Re:WeMo vs. high current devices? (146 comments)

It's a bit more complicated than that. Reactive or resistive loading? Consider a typical portable room heater: A large percentage pure resistive (the heater) and a smaller percentage of reactive loading - the fan motor. Now examine the ratings for our relay - note the disparity in levels handled for resistive load vs "motor" (inductive loads). A typical relay can sport contacts that would handle 1.5KW - resistive. That's about 2 horsepower - but the relay's rating disallows operating motors greater than 1/3 to 1/2 HP (about 250 to 350 VA). And that's our problem - the presence of reactive loads requires a large derating wihich most folks are blithely unaware of. Also it's good practice to "bypass" either motor or relay contacts with a resistor-capacitor "snubber" or an MOV to take up the inductive kickback lest switching this load cause the relay's contacts to fail: %50 rate on fail to close (no *safety* problem) or fail to open - welded contacts, this is a safety problem, aka FIRE!

Disentangling Facts From Fantasy In the World of Edison and Tesla

niteshifter Re:false equivalency (386 comments)

For modern high-voltage transmission, capacitive losses matter even at 50/60Hz. ....

That's an overly broad statement. Capacitive reactive losses really matter a lot on submarine or buried cable. Not much of a factor in overhead HV transmission. Think of it like the classic parallel plate capacitor - since that's what we have, just our "plates" are curved away from each other (which reduces capacitance, but let us consider them as flat here). The area (over the length of the lines) is large, yes. But what kills that off so to speak, is a product of two things: a poor dielectric medium (air) and a large distance (many meters) between the "plates".

For "plates" 3cm wide with a length of 1km and a separation of 10m: about 27pF. In other words: 27pf/km.

Formula: (where's my dang MathML slashdot?) C = k * E * A / S where:
C is capacitance in Farads
k is relative permittivity of the dielectric. Equals 1 (for air)
E is permittivity of space, a constant 8.85E-12 F/m
A is area in meters squared
S is separation distance in meters

For that 1km model above the impedance at 60 Hz is 100Mohm. For a 220KV line that is a loss of about 480W/km. Such a line would be conveying power in the few hundreds megawatt range. Not much of a reactive loss there. Different on sub/buried: k is much larger, and S is much smaller (mm - cm distances).

Ask Slashdot: Wrist Watch For the Tech Minded

niteshifter Re:Don't post while idiot (466 comments)

How does having a smart phone in your pocket hamper you when driving? Just about any car has some kind of clock somewhere so you can tell time.

What if the car's clock doesn't work? Or it's a rental and it's clearly wrong but you haven't a clue or the time to figure out how to set it? That's how the smart phone in the pocket "hampers you". Kinda obvious now that we think about it a bit, hmm?

How about you're a properly careful driver who keeps the road clearly in view at all times which on many vehicles you won't be doing if you are looking at the console clock and with all vehicles the cellphone laying on the seat / center console. With a wristwatch you can always keep the road view near center of your vision.

So to recap: Please, Please, Please .... DON'T FUCKING DRIVE.

Ask Slashdot: Wrist Watch For the Tech Minded

niteshifter Re:Still not answering question (466 comments)

Add to that: Rock climbing / Caving. Non-Sports: Engineering / Maint in heavy industry (like mining / steel / rubber). Cellphones are fragile critters: They won't survive drops of more than a couple of meters. I've a Casio G-Shock that I still use - after dropping it 35m on to rock. Show me a smartphone that will survive even a 10m drop consistently.

Also, some of us just like to know - or need to - the time accurate to 1-2 seconds with no drift to manage. No cellphone does. Certain radio-clock timepieces do well at this, the Casio MTG900 mentioned elsewhere does this (syncs to WWVB signal). Some wireless providers set their clocks evidently by guess or sundial (looking right at AT&T on this one). Mine (ATT, HTC Inspire) frequently is more than a minute off.

Belgian Court Order May Be Too Specific To Actually Block Pirate Bay Domain

niteshifter Re:Classic problem (140 comments)

Which is routinely trampled on for something as simple as "you're blocking traffic"

Simple? No it isn't. The first amendment does not supersede:
A single parents need (and right) to get home to the kid(s) before the sitter leaves / day care closes, or to the school / hospital if the child takes sick, etc.
The right not to die in an ambulance after the stroke, coronary, aneurysm, whatever because it's snarled in traffic.

There's two to get ya started on thinking on what could possibly go wrong with intentionally blocking traffic.

Italian Hacker Publishes 0day SCADA Hacks

niteshifter Re:Why not isolate the networks? (106 comments)

Alas, those old phreaking tricks won't work anymore in places that have moved away from the legacy in-band signaling and control hardware. Which is pretty much all of the civilized world since the early '90's for the PSTN. One could I suppose get lucky with a local PBX - but the attack still requires obtaining access to the PBX controller / software, not just access to modem's phone line.

Bizarre Porn Raid Underscores Wi-Fi Privacy Risks

niteshifter Re:guilty eh? (964 comments)

Yep they surely do. This sparked a thought .... so I checked mine: Sure enough there sits a MAC address. From whatever laptop I used to commission it with in 2002. That was a couple of laptops back.

Then there's this:
$ ifconfig eth1 down
$ ifconfig eth1 hw ether 01:23:45:54:32:01
$ ifconfig eth1 up

So did I copy (or did the router's firmware) that MAC or did I spoof it? I honestly don't remember.

It is possible to uniquely identify a computer on the internet, IP / MAC addressing is not one of them. Accurately would require looking at clock skew, traffic analysis and other time-consuming, trained-brain-required, non-1-click techniques.

Ask Slashdot: How Do You Choose a Windows Laptop?

niteshifter Re:easy (898 comments)

Buy a MS-class laptop with Linux already installed - skipping the WinTax altogether so no need to complain - everything is already configured, except for the custom key strokes you're going to do anyway. Sleep / Hibernate works as well as any other line (and in this post coldboot attack era ACPI S3 can be very foolish to use) , Grab VirtualBox and a retail copy of Win if you really need it. Relax and have a stable system that can operate for years without a crash and enjoy life for a change.

Worked for me .

Back on point as to OP's request: Put Win-whatever-the-wife-needs on the Mac and call it a day. This ain't a purely technical matter ;)

NY Times Asks Twitter To Shut Down Retweeting Feed

niteshifter Re:erm (137 comments)

No, free speech is free speech. The constitutional protections of free speech are applicable to the government.

There is still plenty of sound argument and valid reasoning to want to have free speech that is protected from the actions of individuals and corporations.

You are confused. That last sentence has nothing to do with freedom of speech - what it claims is a right to be heard. You of course, have the right to speak freely. And I have equal right to ignore you.

Microsoft Continues Android Legal Assault

niteshifter Re:Not Microsoft's Fault (344 comments)

I have, very nearly everything she ever wrote - not just Atlas Shrugged / Anthem / The Fountainhead - but all the "hardcore" philosophical writings. She certainly did not build Objectivism on the concept of intellectual property. It's built upon (in a nutshell):

1. The notion that an absolute, objective reality exists, that human hopes, fears, wishes, prayers and the like are immaterial to that reality.
2. Reason is Man's means of perceiving reality and the source of his knowledge and his guide for action,
3. That Man is an end in himself, not the means to the ends of others.

What is true is that Objectivism is friendly with the notion of intellectual property: you've a right to the product of your mind (descends from #3, above). It is a capital mistake to read Atlas Shrugged (a detailed view of objectivist principles in action, in novel form) as defining the philosophy, it's way more than that. For starters read Introduction to Objectivist Epistemology and more to the topic of IP, Captialism: The Unknown Ideal.

I went Galt decades before Atlas Shrugged surpassed Dreams from My Father on the Amazon bestseller list.
