General Software Discussion / Re: Is there a decent youtube downloader?

« Last post by 4wd on January 07, 2013, 08:51 AM »

I think you missed my point about Bulk Youtube Video Downloader, (BYTubeD), addon and DownThemAll!, (DTA).

You use BYTubeD to manage the batch download, (collect URLs, select quality, read from list, etc), and it uses DTA to do the actual download, skipping already existing files.

You don't use DTA for management of the URLs at all and you can choose the target folder - it defaults to whatever is set in Firefox under Options->General.

BTW, if you lost  "1 giga" of drive space after installing Firefox and a couple of addons, you've seriously got something wrong with your installation.  Mine's under 50MB in total including quite a few addons.

Silly question but the path and program do exist don't they?

Otherwise, open a command prompt and try the commands in italics:

C:\>cd \progra~2\spideroak

C:\PROGRA~2\SpiderOak>spideroak.exe --purge-historical-versions d60

C:\PROGRA~2\SpiderOak>batchmode run complete: shutting down        <---- response after a minute or so


Another silly question: You are running Windows 7 x64, right ?

If you aren't, then it's just:

"C:\Program Files\SpiderOak\SpiderOak.exe" --purge-historical-versions d60

or

c:\progra~1\SpiderOak\SpiderOak.exe --purge-historical-versions d60

Should be quotes around the whole path\program:

"c:\Program Files (x86)\SpiderOak\SpiderOak.exe" --purge-historical-versions d60

or

c:\progra~2\SpiderOak\SpiderOak.exe --purge-historical-versions d60

should work if you haven't fiddled with any registry entries

yes, it is a 2.5" external, and yes it does have usb3 ports

This is a usb 2 device, and I've been using the usb 2 ports

-Target (January 06, 2013, 10:57 PM)

Plug it into one of the USB3 ports when you get home.

USB3 ports can supply up to 900mA according to specs, USB2 only supplies 500mA.

Almost every 2.5" HDD needs over 500mA to spin up - if the over-current protection on your USB2 is a bit overzealous or the USB2 interface ICs are "crap", (as some of VIA' chips were), then the drive won't be getting the power required to spin the drive up.

By rights, the drive should have been provided with a Y cable for powering it from USB2 ports, (to provide 1000mA), but they're too stingy to do that these days.



I don't know why it wouldn't have worked going through your self-powered hub but that, naturally, introduces another unknown so best to avoid from the start - possibly the hub also current limits.

That's pretty specific/verbose, but is also very simple.

-Renegade (January 06, 2013, 10:33 PM)

I went for simpler, (read: lazy )

Match: (..).(..).(....).(..).(..)

Also note depending on the renaming program you use, the backreference could be a $ instead of \

Living Room / Re: LED Quality

« Last post by 4wd on January 06, 2013, 10:09 PM »

I wasn't going to reply but then I thought "screw it"

Just to be sure we're talking about the same thing, this is about White High Performance LEDs which are generally what are used in incandescent replacements.

Also fine print. LEDs do produce some heat, although not much by themselves. It is their power supplies that need the heatsinks and are responsible for most of the efficiency loss.

-SeraphimLabs (January 04, 2013, 03:47 PM)

Every LED replacement I've seen, used and built is the exact opposite - the LED generates most of the heat.  They don't produce radiant infrared heat, (as incandescent bulbs do), but the semi-conductor junction within them produces a lot of heat that needs to be dissipated via conduction.

Maximum junction thermal temperature for LEDs is normally specified at ~150°C by manufacturers, (CREE, Luxeon, etc), in their datasheets - at that temperature the LED lifespan is greatly reduced, (eg. from ~100,000 hours @ 30°C to ~10,000 @ 150°C), and luminous output is also reduced.

LEDs are usually supplied thermally bonded to an aluminium slug, this then should be mounted on a heatsink sufficient to reduce the LEDs junction thermal temperature for extended life.

The RAB floodlight you mention uses three 13W LED chips, each of which consist of ~9 LED emitters arranged in 3 columns.

Here's a LED Junction Temperature calculation for a 6 emitter 11.76W chip:
Calculating LED Junction Temperature in Lighting Applications

A calculated junction temperature of 262.9°C.

Here's a calculation for the heatsink requirements of a 14.6W LED chip:
How to calculate your LED heat sink

Drivers for LEDs are very efficient these days, anywhere from 80-95% - you can get them for outputs up to 20W or more that don't need heatsinks - even the 70W versions are in small metal boxes that don't require any extra heatsinking.

The RAB 39W floodlights use the whole front of the floodlight, (reflector/housing), as one big heatsink with fins to ensure the LEDs stay cool enough to achieve their 100,000 hour rating.

If you were to open it up, remove the LEDs from the housing and just hold them while you turned it on, I pretty much guarantee you won't be holding them for long.

The exact same thing can be seen in the MR-16 (12V AC/DC) and GU-10 (90-265V AC) replacements, the LEDs are mounted on the heatsink, the drivers have none.

The author of the junction temperature calculation above mentions that ~70% of the input power to the LED is converted to heat.

Fact or Fiction – LEDs don’t produce heat

And FWIW, here's an article on how to drive an LED at over 100% efficiency but at 69 picowatts of of optical output I don't think you'll be lighting up the backyard any time soon.

That said, the lite on the drive flickers, so there is something happening

-Target (January 06, 2013, 05:43 PM)

That seems to me like the drive isn't spinning up, when you plug it in do you hear the drive spin up ?

Or, do you hear nothing or a soft clicking ?

-4wd (January 06, 2013, 09:11 PM)

nothing, but that's normal, ie when I use the drive normally (on the laptop) it makes no noise either

-Target (January 06, 2013, 09:39 PM)

Press it against your ear, I've yet to hear a completely silent HDD

Plus you should feel it vibrate.

would the drive spin up if it wasn't detected?  I don't know anything about the low level operation of these things, but I would assume not, as it wouldn't get any indication from 'the system' to do so

I've yet to see an external HDD, (2.5" or 3.5"), not spin up when first plugged in, (doesn't mean they don't exist), but I did have a external Seagate, (and others), that goes to sleep after inactivity.

The flashing LED you mentioned above normally indicates to me, (in the case of a 2.5" external), a lack of power to spin the drive up, (which sometimes results in a soft clicking).

BTW, we are talking about a 2.5" external ?

Also, does the computer in question have any USB3 ports ?

I'm always amazed by some people's reaction when I let my phone "ring through" to voicemail.

-40hz (January 06, 2013, 05:23 AM)

No redirection or call-waiting, (I'm not paying for the extra calls generated), on my mobile and landline so in theory it'll ring for 60-90 seconds before it times out...but off course the impatient people ringing won't let it get past 20 seconds before they hang up 

That's fine, if it's really important they'll ring again

I meant to also add, it might pay to reset your BIOS to defaults and then make sure any USB settings are all enabled.

BTW, with most modern computers any USB storage device should show up in the Boot list, (when you press F11 or F12 usually at boot instead of Del), does it ?

If it's not showing up in the boot list then that might indicate a problem with either BIOS settings or the motherboard.

Something easy to try, plug the drive into a USB 2.0 port on the suspect computer and boot off of a Linux LiveCD - it will at least isolate it to software or hardware.

Use CFLs for lights that remain on for a long time, use incandescent for short term use, (eg. toilet), and replace all the stupid MR-16/GU-10 halogens with LED versions.

Probably the most economical way to go until LED incandescent-equivalent light bulbs come down to reasonable prices.

Because LEDs don't produce heat, less heat is released into your house making it easier to cool.

Slightly contradictory content - LEDs, (as used in incandescent replacement), produce heat - it's why they're stuck on heatsinks.  If the heatsink isn't big enough for the job, then they will fail prematurely.

All-in-all it was a pretty useless article that had nothing to do with "Learn the difference between good and bad LEDs".
