The Great Lightbulb Conspiracy

dkegel CFL failure rate data: some vendors good, some bad (602 comments)

The Energy Star folks eventually did realize that there were a lot of shit CFLs out there, and started doing rigorous testing; see http://www.energystar.gov/ia/p... They now actually test bulbs before giving them the Energy Star seal.

When they started doing Energy Star ratings for LEDs, they tried really hard to avoid the CFL fiasco; see http://www.gizmag.com/energy-s... As a result, Energy Star rated LED bulbs are pretty reliable. I have about 60 (!) in my house, bought over the last 9 months. None of the Energy Star bulbs has failed yet. Two non-energy-star LED bulbs that were several years old (from vendors not around anymore?) did fail.

I'm now slowly converting the bulbs in the house I rent out to LEDs, with the tenant's cooperation. The only two bulbs she has liked so far are the Cree 40W TW http://www.creebulb.com/Produc... (for bathrooms only - it hums too much for living room) and the Phillips 40W A15 ( http://www.homedepot.com/p/Phi... ) for everywhere else. Her dimmers are old, and most LED bulbs flicker with them; I should get her newer dimmers. Haven't had that problem much at my house.

I'm quite happy with the LEDs so far, and am writing up my experiences at http://kegel.com/energy/lights... Your mileage may vary.

New EU Rules Will Limit Vacuum Cleaners To 1600W

dkegel Re:US Energy Star and vaccuum cleaners (338 comments)

I stand corrected. (Thought there was a three-order-of-magnitude problem in there, actually, but didn't see where.)

So it's 67 GWh annual savings in US vs. 19 TWh annual savings in EU, then? Seems like one or both of those estimates is still way wrong.

New EU Rules Will Limit Vacuum Cleaners To 1600W

dkegel US Energy Star and vaccuum cleaners (338 comments)

The US doesn't have Energy Star standards for vacuum cleaners yet, but they're thinking about it.

http://www.energystar.gov/ia/p... says
"[Assuming efficiency improvements of 16% to 33%...] Estimated per-unit annual savings for residential vacuums are on the order of 10-19 kWh/year... Considering there are approximately 28 million vacuums sold in the U.S. each year, the national energy savings opportunity would be on the order of 67,000-135,000 MWh per year if 25% of products sold were replaced with energy efficient models"

Contrast that the the document linked in TFA:
http://ec.europa.eu/smart-regu... says
"[Vaccuum cleaners sold per year in 2005 and 2020: 54 million and 92 million]... [Energy consumed by vacuum cleaners under business-as-usual by 2020: 29.7 TWH/year]... by 2020, the annual electricity consumption ... of vacuum cleaners will be reduced by 19 TWh"

So, 67 TWh annual savings in US vs. 19 TWh annual savings in EU in spite of twice as many vacuum cleaners sold per year in the EU. Is there just more dirt in the US? Or was the Energy Star scoping report just overoptimistic?

People Who Claim To Worry About Climate Change Don't Cut Energy Use

dkegel Re:LED Lightbulbs Re:user error (710 comments)

Me, too. I get mine at Home Depot (they have Cree, which I like better than the ones at Lowe's). Replacing frequently-used incandescents with LEDs pays for itself in about 9 months (at $10/LED, 4 hr/day, and $0.15/kwh; your milage may vary, see http://www.lektroninc.com/payb... )

Doing this (and a few other things) cut my power usage from 40KWH/day to 25KWH/day. Still too high... I need to dig some more to see where it's all going.

I'm blogging the experience at http://kegel.com/energy/lights...

Valve Sponsors Work To Greatly Speed-Up Linux OpenGL Game Load Times

dkegel Nvidia's been doing this for a while on Linux (202 comments)

FWIW, the Nvidia proprietary drivers have had a shader cache on Linux since the 290.03 release in late 2011 (search for GLShaderDiskCache). It probably helps Mass Effect 2 under Wine somewhat (here's a bug report from before the cache was added to the driver: http://bugs.winehq.org/show_bu... )

DHHS Preparing 'Tech Surge' To Fix Remaining Healthcare.gov Issues

dkegel Re:Spot-checking healthcare.gov (429 comments)

I only logged in, since I live in a state that doesn't use the Federal system, so I didn't want to fake my address (beyond saying I lived in a different state, which was good enough to get past the account creation process).

Just how broken is it? Let's find out.

I tried creating an account early Sunday morning and failed.
I tried again Sunday evening, and it worked... on Firefox, anyway. On Chrome, logging in took me to a blank screen.
( See https://plus.google.com/u/0/113779301404424240904/posts/2mxh2wPTein )

If you try creating an account on healthcare.gov, reply here with what happened. Let's see how broken it is.

The Decline of '20% Time' at Google

dkegel Re:I doubt the reports... (198 comments)

Are you talking about Google, or some other company? I don't remember anything like that going on at Google when I was there. The managers I observed were quite levelheaded and didn't assign too much work. The only real impatience I saw was when one product had too much latency visible to the end user. That resulted in a whole lot of impatience... and a new level of vigilence against latency creep. But that was a good thing.

The Decline of '20% Time' at Google

dkegel I doubt the reports... (198 comments)

The original report of "For many employees, it has become too difficult to take time off from their day jobs to work on independent projects." can be explained well like this: people who are below average productivity in their team can't spare the time to work on 20% projects.

I don't think this is a harsh thing; it's just a fact of life.

By the way, the Google version of stack ranking (if I recall correctly from my time there) is something like "If you're a manager, and there's a guy on the team who isn't being very productive, make sure he knows about the problem, so he can do something about it."

Also not a harsh thing.

Google doesn't want to become a Cisco, where all the good ideas come from buying up little companies. I suspect that people of above average productivity at Google still have plenty of freedom to try experiments 20% time.

What has changed a bit is that since the mantra of the company became "Features, not products", those 20% experiments are almost always going to involve adding features or other improvements to existing products, not wholly new products.

And that's ok, too. There is a whole lot of room to add features and make things better under the hood.

Millions At Risk From Critical Vulnerabilities From WordPress Plugins

dkegel Re:Let's keep the tree green (145 comments)

Congress, say.

And of course 'instantly' would be too gestapo for real life. We'd really want a grace period with escalating warnings, followed by fines, followed by pulling-the-plug.

And it'd be much better if industry came up with this on its own first. What's the state of the art?

Rackspace talks about security,
but doesn't seem to offer proactive vulnerability scanning, and if they did, they would charge for it instead of just doing it.

Godaddy seems to offer this as an extra cost
service instead of just doing it:

Here's one wordpress hosting provider that promises to install all security updates within one hour (wow):

So, industry guys, can we get our act together and offer security scans and upgrades as part of the basic service plan?

Millions At Risk From Critical Vulnerabilities From WordPress Plugins

dkegel Let's keep the tree green (145 comments)

The solution is easy: hosting providers should be required to continuously run vulnerability scanners, and instantly take down any sites which have known vulnerabilities. As a bonus, it would clear out a lot of crap sites.

Ask Slashdot: New To Linux; Which Distro?

dkegel Re:vanilla Ubuntu. (573 comments)

+1 to that. Don't try to customize so much. Just use Ubuntu 12.04 (or 12.10) the way it comes. Once you've used to that for a month, then maybe customize. But don't go fooling around with E17 or the like until you're quite sure you know what you're doing.

Attachmate Fires Mono Developers

dkegel Mono does work with wine... (362 comments)

Mono + wine, of late, were starting to be able to run some of the .net apps associated with games. For instance, if you ask it very nicely, mono + wine can run the Need For Speed World launcher/patcher (and was able to do so before .net + wine could). There are lots of bugs left to fix in mono before it can handle more .net 3-era apps, let alone WPF apps, which would be Really Hard.

Microsoft purges download area of everything pre-Vista?

dkegel dkegel writes  |  more than 2 years ago

dkegel (904729) writes "Over the last couple weeks, many downloads at microsoft.com related to older versions of Windows have been silently deleted. For instance, Service Pack 2 for Windows XP, which used to be at www.microsoft.com/en-us/download/details.aspx?id=28, is no longer there.

It seems that a) Microsoft is getting quite serious about ending even any hint of support for end-of-life operating systems, and b) the era of being able to download individual fixes via the web is ending; the future is automated updates."

LA Times defends software patent troll

dkegel dkegel writes  |  more than 3 years ago

dkegel writes "Remember PanIP, the outfit that was suing e-commerce sites back in 2002 and dropped their suit after the Patent Office invalidated the patents? Well, the LA Times has written a sympathetic story casting him as the underdog.
It seems that the LA columnist isn't aware of the debate over software patents.

I emailed him just now explaining it a bit, linked to ./'s articles and wikipedia's articles on the lawsuits, and suggested he do a followup article showing the other side of the story.

(A few more emails to the guy might help drive the point home, but please don't send him hate mail, he's just a journalist trying to do his job, and vitriol would probably make him think that the Evil Conspiracy Against The Inventor was real and still active.)"

Chrome for Mac and Linux dev builds announced

dkegel dkegel writes  |  more than 5 years ago

Dan Kegel writes "Mike Smith and Karen Grunberg, Product Managers for Google Chrome, write in http://blog.chromium.org/ :

"In order to get more feedback from developers, we have early developer channel versions of Google Chrome for Mac OS X and Linux (for a couple of different Linux distributions), but whatever you do, please DON'T DOWNLOAD THEM! Unless of course you are a developer or take great pleasure in incomplete, unpredictable, and potentially crashing software.

How incomplete? So incomplete that, among other things , you won't yet be able to view YouTube videos, change your privacy settings, set your default search provider, or even print.

Meanwhile, we'll get back to trying to get Google Chrome on these platforms stable enough for a beta release as soon as possible..."
