Micro USB PC Data Sync Cable for Blackberry
Focalprice.com offers Micro USB PC Data Sync Cable for Blackberry
available at $1.43 (for 3 units) or 1.91 (for one unit). I wish I could use it along with my BB Curve 8530.
If you're looking for some low priced gadgets, accessories or electronics, Hong Kong based online retailer FocalPrice.com is worth checking out. They're quite similar to DealExtreme.com. All prices are in US dollars and shipping is free for all items. Keep in mind items are being shipped from overseas, so orders may take 2-4 weeks to arrive.
Dealextreme has this for $1.2. but it seems like really poor quality, as mentioned my multiple reviewers.
Monoprice has this for cheap at 97 cent (it's a daily deal).
Meritline seems to be expensive at 2.54.

I was going to buy Denon AVR-791 AV receiver
[Elect] Denon AVR-791 AV receiver $430 at FS, PM at at BB for $408 ($650 regular price) - RedFlagDeals.com Forums: "Denon AVR-791 AV receiver"
The price after PM at Bestbuy is $408 which is pretty much the cost of the receiver. But it doesn't have a component output. So until I buy my new TV, I will have to use the low quality composite video. I will wait for some Onkyo 608 or lower to go on sale, they have less price, but has component output.
But still I'm not sure if I pass on this deal.

Tummy time for babies.
Well, I heard about this concept today. The nurses told us that babies should be on their back. So we never cared to put him on his tummy. Now I read that tummy time is important. Tummy time is nothing but time spent by baby on his tummy. It is not bad to have 5-10 min tummy time, couple of times a day. It helps his neck and gives him a new perspective.

Breather pipe - Tank design
Well, My boss told me that the design is governed by API 2000. I tried to read it, but it's no fun. So I downloaded a spreadsheet, which does all the calculations. It calculates the breather valve diameter, based on the limiting case, I think fire case is the limiting case. API 2000 has some correlations for different cases. I found that the current diameter for the breather pipe is sufficient.
Now my company specs says all tanks must have a breather pipe of good neck type or mushroom cap type. Since we are specifying something difference (a straight pipe without mushroom cap), we need to issue a technical deviation (TDS).
A good resource

Spreadsheet calculations (credit to original author) here
Equations for normal venting, which should help:
Inbreathing:
If tank capacity <= 3500 m3
Total Inbreathing = Pumpout + 0.178*tank capacity (m3)
If tank capacity >3500 m3
Total Inbreathing = Pumpout + 3.2*(tank capacity (m3))0.651
Outbreathing:
Liquids with flashpoint >37.8 deg C or NBP above 149 deg C
If tank capacity <= 3500 m3
Total Outbreathing = 1.069*Pump-in + 0.107*Tank Capacity(m3)
If tank capacity > 3500 m3
Total Outbreathing = 1.069*Pump-in + 1.92*(Tank Capacity(m3))0.651
Liquids with flashpoint <37.8>
If tank capacity <= 3500 m3
Total Outbreathing = 2.138*Pump-in + 0.178*Tank Capacity(m3)
If tank capacity > 3500 m3
Total Outbreathing = 2.138*Pump-in + 3.2*(Tank Capacity(m3))0.651
Note: The Pumpout and Pump-in are given in m3/h.
Vent to be sized for the maximum of the inbreathing or outbreathing rate.
