Slashdot's editor team knows that the "audience" here hate Bennet Hasleton's continued long winded drivel, yet they keep posting his stuff regularly.

This yet another clear sign that Dice and Slashdot do not care about their "audience", continuing off from the Beta debacle.

Just keep ignoring your "audience" while expecting viewership to increase. Yeah, that will happen alright ...

Comment: PRT, SPF, and DKIM (Score 1) 405

by kbahey (#48382183) Attached to: Ask Slashdot: How To Unblock Email From My Comcast-Hosted Server?

I had similar issues, though on a machine hosted outside my home network.

The solution was to implement SPF, pointing to the PTR of machine (i.e. what a reverse IP lookup will resolve to), and DKIM.

In your case, doing a PTR will be hard, since dynamic DHCP may change what the PTR is, but the rest does apply.

I wrote the following detailing what I did: Setting up SPF and DKIM on Postfix.

I had lots of mails bounce after Yahoo implemented DMARC.

However, with a bit of patience, I was able to implement DKIM and SPF for my domain, and now all the mails get delivered to Yahoo addresses.

I wrote about how ot configure SPF and DKIM in this article: Setting up SPF and DKIM for Postfix.

Things were easy until the mid to late 19th century. Anything could be produced in a carpenter, blacksmith or watchmaker's workshop. Lenses were ground, metals were machined, ...etc.

Then in the early 20th century things started to get far more specialized. By the mid 20th century, we had the transistor then the integrated circuit.

Now, everthing from ubiquitous phones to home appliances to street lights have complicated integrated circuits, CPUs, RAM, ...etc. that can only be designed by specialized teams, and fabricated in very high tech fabs.

Contrary to all the speculative guesses in the comments, the researchers do have a hypothesis for this.

From the linked PLOS article:

Unique among the senses, the olfactory system depends on stem cell turnover, and thus may serve as an indicator of deterioration in age-related regenerative capacity more broadly or as a marker of physiologic repair function

/bin/sh is linked to /bin/bash and vulnerable

Not on Debian/Ubuntu. On those, /bin/sh is symlinked to dash, which is not vulnerable to Shellshock.

To test this, I created a small PHP script, as follows:

$ cat > x.php
<?php
system('echo hello there');

I run the php script, and do an strace following children:

$ strace -f -o output php x.php

In the output I find this:

28302 execve("/bin/sh", ["sh", "-c", "echo hello there"], [/* 24 vars */]) = 0

I had to deal with a remote customer whose person on site does not speak English, by getting him to enter UNIX shell commands. His native language (and mine) was Arabic.

What I did was to tell him what Arabic key to press so that the English equivalent would be the one sent to the shell.

We were lucky that his Arabic keyboard layout was the same as mine. That was not a given in those days (Late 80s, early 90s), but we lucked out.

He was describing to me the output in English (vertical bar, vertical bar with a circle at the bottom, ...etc).

It worked out and we solved the problem in less than an hour.

Comment: They store credit card data with the transaction (Score 5, Informative) 132

Home Depot stores credit cards with the transactions.

I know this because when you go to return something I bought, they don't ask you for the credit card, and sort of highlight that this is a convenience that is unique to Home Depot.

I complained more than once to the cashiers about storing credit card numbers (it is not their fault, it is management and IT). The cashiers would say: "Don't worry, we don't have access to it!"

My response was: it is not you whom I am worried about.

Now we know that storing credit cards is a bad idea, and why ...

by kbahey (#47681221) Attached to: Ask Slashdot: What Recliner For a Software Developer?

I work from home, and have been using a recliner as my only "desk" for about 6 years and have the following to share ...

- My recliner is a La-Z-Boy. Can't remember the model since it is has been many years, but it is not something fancy. I tried leather for a little while, but it can be sweaty and sensitive to even your finger nails. So I have been using fabric.

- If you recliner has a wall behind it, then move it away from the wall a bit so it can recline back.

- Your LEGS (calves and feet) will feel better on a recliner.

- Use a pillow or something to support your NECK. It will feel better.

- Watch for your BACK. Put a stiff-ish wide pillow below you if you feel like you bottom is sinking in the chair. Also, put another stiff-ish wide pillow behind your lower back. Experiment with different pillows until you find the right combination.

- Avoid any FANCY back support that curves your spine too much. These are the most common ones on the market in my experience. This includes the wire frame lumbar support mesh thingies (they aerate well, but will hurt your back because of too much spine curvature), or those cylinder shaped hard pillows.

- Use a LAPDESK (those foam filled sacks with a vinyl covered plywood surface).

- Get a table that is level with the arm rests beside you so you can easily sip your beverage of choice, and have some handy items too (pens, paper, mobile phone, ...etc.)

- You will be absorbed in whatever you are doing, so interaction with the wife and kids will be mostly "huh? what did you say?" or "later, I am focusing on something else here" ... Not quality time ...

How timely. I am doing a presentation at the local LUG (KWLUG) on OpenWRT in a couple of days.

There are various options out there that are supported by OpenWRT.

In this day and age, you want the most memory and flash that you can get, gigabit ethernet, Wirless N dual band (2.4GHz and 5GHz), as well as USB.

I use The D-Link DIR-835, which has 128MB RAM, 16MB flash (the most memory and flash that you can get for a reasonable price) and all the above features . It goes for ~ $80 in Canada.

There are other options that support most of the above, but with a bit less RAM or flash sometimes, but perhaps 2 port USB, ...etc.

They are:

TP-Link WDR-4300 ~ $70
TP-Link TL-WDR3600 ~ $55
TP-Link TL-WR1043ND ~ $50

All of the above are supported on OpenWRT development snapshots (soon to be a stable release, Barrier Breaker).
