Image note bug solution

As far as I have noticed, the bug is activated when a colon is in the text. I had errors many times when making image notes - and I tested in three different browsers (where the error just looked different). But only in texts that included a colon. Each time I removed colon from text: no error. It might be the same for other special characters. Hope it helps :)

Fixperts - Designers doing something useful!

I was recently alerted to Fixperts.org. It's a fascinating concept - "real" designers get paired with folk with actual, unsolved problems (typically related to a mobility issue), and produce bespoke solutions, making a nice little video in the process. Introduction to Fixperts from Billo on Vimeo. It's mainly a UK thing at the moment (some of the folk from Sugru are involved, although it's not a Sugru scheme), but there's nothing stopping you, dear reader, starting up something similar through your own school, college or Hackspace. There are even guidelines on the site on how to join in. I've been told of companies that make bespoke prosthetics, or connect problems to solutions, but this is the first voluntary group I've encountered that drags Design out of the showroom or gallery, directly to those who actually need these skills now. I'm going to keep an eye on Fixperts, and I think you ought to as well... @Fixperts

Solution to computer problems (Windows 7???, hardware???)?

I had asked 2 questions about my 6 weeks during computer problem:' is Windows 7 That Bad??', and 'help'... Windows XP seemed to get slow and somewhat erratic, so instead of re-installing XP, I installed the 64b version of W7 ultimate, downloaded as 'freeware'. It was a chore to install, and much of my hardware was not recognized (no network port (= internet), only generic CD ROM instead of DVDRW, etc.).  Problems shutting down, and SLOOOOWWW. So after a while, I re-installed my trusted XP, but things did not get better (at all!). This was not normal! Since my HDDs came on and off, I figured it ought to be the motherboard. It always (2 1/2 years) worked fine, but after some internet search (I also do have a laptop), it seemed to be one of the worst MBs ever made... But a spare laptop HDD got fried instantly (motor+ is dead)... So I ordered a new one: A nice old fat Asrock, with 4 memory slots, and 7.1 sound.  It lasted 4 hours... No more picture, not by the board, not by the added card... By warranty, the MB might have been bad, so I got the replacement. But I did not trust my TRUST power supply anymore. So I bought a new 500 GB HDD and new (Cooler master 460 W power supply). Everything was wired up, Windows 7 installed, and it runs great!!! The laptop disk is dead, but my old system disk is most often recognized...  There was still a lot of important, non backed up data on it (!). I was able to secure all of it!!! So my conclusion is: it probably was the power supply: don't trust TRUST!!!

If you have an overactive bladder, here's some advice.

First of all, I would just want to say that I have procured this advice from my own personal experience.  This is what I do. Tip 1- STOP DRINKING COFFEE!  It's amazing how the people who buy bladder control medicine are the same people who drink coffee, which contains a substance known as caffeine.  Caffeine does give you that 5 second energy perk, but then this is followed by you taking a piss in the toilet ever 20 minutes because it's a diuretic substance.  And at this point I am not just talking about coffee either.  Most sodas contain quite a bit of caffeine as well. Tip 2- Drink less water.  I know how people need water to survive, but I am not saying to stop drinking water, I am just saying to reduce your watery intake.  I was sick with Swine flu a few weeks back, so my mom forced me to drink gallons of water each day.  I ended up having to get out of bed every 30 minutes to use the bathroom, and this ruined the whole resting pattern. I'm just sick of seeing so many advertisements about bladder control medicine.  I don't care, just get back to that awesome show I was watching!   Help boycott bladder control medicine and get those advertisers to shut the heck up. (Unless of course you have a real medical condition and for some reason more bathroom use is a side effect, then none of this applies to you)

Chemistry Questions: What do you get from combining salt, white vinegar and cupric oxide? And what can be done with it? Answered

In my enameling work, I sometimes use a mild homemade pickling solution to remove firescale (cupric oxide) from copper. The pickle is a saturated solution of white vinegar and kosher salt, kept hot in a Crock Pot. After heating the copper pieces in a kiln, a layer of cupric oxide forms on the surface, which is then dissolved in the salt/vinegar solution. After a while, the solution turns a lovely blue color from the dissolved copper. If I forget to put the lid on the pot, eventually the solution evaporates, leaving pretty blue crystals that look a bit like copper sulfate. So, what have I got here? I don't want to just dump it due to the copper content. I'd like to figure out something to do with it, but first I need to know what it is. I'm thinking it might make a good electroplating solution, but that's just a guess.

How to build a 5Kwh Power Wall using Headway 38120 LifePo4 Batteries

Frequent power cut during the summer and hours of no power issue during the monsoon makes our lives miserable. It's a common picture in rural areas where the overhead power line connection is prevalent. This led me to think about an alternative power back up that would be way better than the conventional LA or SLA battery solutions. With the constant advancement in the technology, new dimensions are being unfolded to us and I believe, the powerful Headway 38120 batteries are going to reign in the market for quite sometime. I need help from the experts to build a 5kwa Power Wall using Headway 38130 LifePo4 cells and an Inverter too. The parameters are: Output Voltage: 230v, Max Load: >500wh (I'm looking for 10hrs bkp= 5kwh), I'm clueless about how many cells I might need and how many of them will be in series and in parallel connection. Do I need a custom built charger for these LifePo4 cells and BMS too? Please help me up.
