Ask Slashdot: PC-Based Oscilloscopes On a Microbudget?

cpotoso xprotolab or teensy 3.1 (172 comments)

xprotolab or teensy 3.1

Check out xprotolab ( from Gabotronics. Not too fast or too easy to use but it is very capable and Gabo provides very good support. It is self-contained (small oled screen) but can also send info to PC over USB.

Also, the "arduino" teensy 3.1 could be used to make a USB-based scope for ca. $20 (plus some additional parts) and can have a lot of other cool uses too. Check it out: and

Siphons Work Due To Gravity, Not Atmospheric Pressure: Now With Peer Review

cpotoso Not "Nature", a lesser journal of the Nature group (360 comments)

The 2012 Impact Factor for Scientific Reports is 2.927. For comparison, that of Nature is 38.597. Still impressive, but please lets be precise.

Netflix Plans To Raise Prices By "$1 or $2 a Month"

cpotoso Re:Milk that cow! (202 comments)

What are you smoking?? WE pay for the internet service (monthly bill, anyone?). So why should Netflix have to pay on top of that?? The infrastructure? Yes, coming from your monthly bill. Duh!

The $100,000 Device That Could Have Solved Missing Plane Mystery

cpotoso Re:Does it really cost $100k? (461 comments)

Your posting is close to non-sense. Who is saying that every Cessna 172 should have this device? We are talking about AIRLINERS, and in particular those that go transoceanic routes where radar tracking is not possible. On a 767-sized plane (and above) the $100k cost IS negligible when compared to other operational costs (fuel, crew, maintenance, insurance).

China Deploys Satellites In Search For Missing Malaysia Airlines Flight

cpotoso Why aren't big planes PERMANENTLY monitored? (142 comments)

I am not talking RADAR, but rather satellite-linked transponders relaying (at least) once per minute the plane "vitals" (coordinates, velocity, altitude, attitude, cabin pressure and temperature, fuel levels, any error codes or warnings). I mean, this may not be cheap, but it is meaningless cost-wise compared to the operational cost of a plane.

4 wheel drive dowes *not** equal 4 wheel STOP.

And I thought all cars had breaks on all wheels... (4 wheel stop). Was I wrong? Maybe I should check my car again.

Death to the Trapezoid... Next USB Connector Will Be Reversible

cpotoso Re:Even worse... (408 comments)

What a S T U P ID reply. What is the orientation of the connectors in the back of a computer? In a random USB hub? Why the need to look for the logo when the shape of the connector could convey the correct orientation? (or even better, be orientation neutral). Do they pay you to use your brain in your work, or just brute force?

Death to the Trapezoid... Next USB Connector Will Be Reversible

cpotoso Even worse... (408 comments)

Is the fact that the standard USB connection (rectangle) is not really 180 degrees symmetric (despite a shape that indicates it should be), usually takes 3+ attempts to get it in. Damn it, Jim, a spin-1/2 connector!

Gift Review: Strandbeest Model Kit

cpotoso I gave it as a gift, it is VERY NICE. (28 comments)

Took about 30 min to build by a 11 year old. Mechanism is nice, looks nice too. Played with it for 10 minutes and then it is now on the shelf (a nice ornament ready to show to some friends). Overall I really liked it. Reasonable price too (though I found it for $15 on a chinese site).

Man In Tesla Model S Fire Explains What Happened

cpotoso Re: Good Engineering Tesla (526 comments)

Considering the very small number of tesla's out there, I would say the safety record is thin. Yes, other manufacturers had their problems, but with a baseline of MILLIONS of cars, their safety record is not so bad. It is always a matter of ratios.

Mac OS 10.9's Mail App — Infinity Times Your Spam

You are literally demanding perfection. Exactly how many professions are there where people don't make mistakes?

Well... programmers seems to be among the worst...

Mac OS 10.9's Mail App — Infinity Times Your Spam

cpotoso Re:Whar is wrong with programmers? (158 comments)

The comparison is absolutely nonsense. When you write a book you almost always start from scratch, so yes... errors can creep in on book 10^9 at the same rate as on book 10^0. When you write code that is an update to an old software, you re-use a lot of the old code. So, there is no excuse for that.

Mac OS 10.9's Mail App — Infinity Times Your Spam

cpotoso Whar is wrong with programmers? (158 comments)

I mean, it is a MAIL program, not a revolutionary new product. The protocols have been out there for years (esp. IMAP). Why is it still buggy? Even worse: why is it buggier than the previous version? If it worked before THERE IS NO F*ING EXCUSE FOR IT NOT TO WORK NOW. Very very very lame.

Middle-Click Paste? Not For Long

cpotoso What a piece of crap! (729 comments)

Several years ago I used to run my desktop in linux (slackware!). Later distros started to look more and more like windows. Only took a few iterations until I got tired of that crap (seemed all programmers now think like microsoft programmers, !@#$!@#$%%!$%). Now I run linux back-ends and my desktops are OSX, never looked back.

In China, Human Costs Are Built Into an iPad (nyti

cpotoso cpotoso writes  |  more than 2 years ago

cpotoso (606303) writes "In the last decade, Apple has become one of the mightiest, richest and most successful companies in the world, in part by mastering global manufacturing. However, the workers assembling iPhones, iPads and other devices often labor in harsh conditions, according to employees inside those plants, worker advocates and documents published by companies themselves. Problems are as varied as onerous work environments and serious — sometimes deadly — safety problems."
