S&R Pampanga sale 2012 part 1

.

Disclaimer: I am in no way connected to S&R or any of its subsidiaries. I have not been paid by anyone to write this. Like all entries in this blog, its is an honest record of what I have experienced. Mostly this blog is about computer or tech related stuff so this is one of the few non-tech related posts.


So, from the picture above, you know that S&R's sale is going on. I am going to explain what S&R is, why shopping in S&R is worth it and how you can save money in S&R. In part 2, you will see an list of some interesting good buys that I saw during this sale. I wrote them down on my smartphone as I was perusing the merchandise.

This is S&R's website. This is their Facebook page.



OK, S&R, unlike other supermarkets is not open to the general public. You need to apply for membership before you can buy anything. Membership usually costs < 1000 pesos a year. If you apply within the store, you immediately get a temporary card so you can immediately go shopping. You pick up your official card after a few days.

Why does S&R require membership? Well one reason is psychologically, you feel that you have sunk several hundred pesos into the membership, you might as well shop there to make it worth it. Another reason is, presumably, the cards are used to statistically analyze shopping behavior. I have no proof as to whether or not this is done but all the big retailers do it. It might sound like a creepy invasion of privacy but AFAIK its not illegal and you have the choice to shop somewhere else. Also, I heard somewhere before that due to a loophole in taxes, if you sell to the public, you are taxed so and so but if you sell to only members, they are not considered the "public", i.e., its not a retail store. So you get taxed less. I have no idea if this is true or not or whether it applies to Philippine laws or not.

So, what makes S&R potentially cheaper? First of all, its not an ordinary supermarket, it's a warehouse club.

A warehouse club is a retail store, usually selling a wide variety of merchandise, in which customers are required to buy large, wholesale quantities of the store's products, which makes these clubs attractive to both bargain hunters and small business owners. The clubs are able to keep prices low due to the no-frills format of the stores. In addition, customers may be required to pay annual membership fees in order to shop.

You can see it in the way the building is laid out. In S&R a large number of items are available in large quantities like 50 items or more per bundle. So you do save sometimes due to buying in bulk. Warehouse clubs save money by not having 2 buildings, a warehouse and a retail store. They just have one big warehouse. The shelves may be 2-4 stories high and the bottom shelves are the retail store. The top shelves are where the items are stored. So they don't have to pay for 2 buildings. And they pass the savings on to you.


I read one article once in the inquirer where a financial analyst gave advice on what to invest in if you had some extra money. One minimal risk investment is to buy in bulk stuff that doesn't fluctuate in price much (or only goes up in price) and can be stored for a long time. Its hoarding essentially and yes it usually works.You buy stuff at a discount, how can you lose?

These are all theoretical but do I see them in practice? Well, sometimes. Personally, yes there are a few items that are cheaper than in other supermarkets because they are in bulk, specially during sales. But I decided to get an S&R membership for other reasons. The main reason is S&R stocks a lot of brands and items not found anywhere else. Another reason is their great reasonably priced pizza which can be bought from their in house cafeteria style restauraunt. I figure that by shopping a few times specially during sales and carefully choosing what I buy, I can recoup the cost of the yearly membership fee. Unfortunately, sometimes I find myself buying more expensive bu tastier brands, lolz.


OK, end of part 1. Go to part 2 for a list of interesting items that I found during the sale.

Opening PWI files

.PWI files are files created by the notes application in windows mobile cellphones.

You can open them on a desktop PC by using MS word. I tried word 2010 only though so i'm not sure if older versions would work.

First, prepare word 2010. Open it. Go to file > options > advanced. Now scroll the right pane down to the bottom and check confirm file format conversion on open.

Now open the .pwi file with ms word 2010. In the convert file dialog box, choose Recover text from every file.

Its not perfect, there may be a few stray formatting marks like line breaks but at least the text is there.

paypal on cellphones






source

This is a card swiping accessory that attaches to an iphone which enables a seller to accept credit card payment. This one is for paypal but there are other similat companies that provide the same thing. This has been my dream for a long time, for ANY business in the philippines to be able to accept credit cards, including theoretically a fishball street vendor, all you need is a net connection.

But my dream has a part 2. Part 1 actually has been possible for some time, just use a card swiper with a battery and the guts of a cellphone inside.




But this violates part 2 of my dream, affordability. Because afaik such card swipers have expensive monthly fees. So its no good for a seller unless credit cards are used frequently.

Part of making it cheaper is for the chinese to copy it (even though the paypal one above will be heavily subsidized) since it increases competition and user base and gives us many feature choices.

cdrking earbud review


Model SE-107 e cdrking earbuds

I was in the market for cheap backup headphones for my laptop. So I looked around. These seemed OK. I chose them since at 180 pesos, they were at the higher end of the low quality earbud price range and I was hoping that the quality would be better. I also chose these for the symmetrical cords. I don't like asymmetrical.

I've only had them for one day and I know that they are cheap. So I didn't have my hopes up and my rating is skewed to the fact that its cheap.

Build quality - its OK. Cord and the rubber at the tip is less flimsy than some of the 100 peso counterfeit sony or beats by dr dre headphones. Cord length is ok but on the short side. I'd give it a 3/5.

Accessories - no pouch. No tip protector. With 2 extra rubbers of different sizes. I'll give it a 3/5.

Sound quality - muddy, bias towards base. I prefer crisp tones. Markedly worse than my Altec Lansings. 2/5

Verdict - I wouldn't buy these again. I should have saved 500 pesos for some Sony earbuds. Lets round off the final score to 2/5.

the end

Update: forgot to say that the comfort and fit of the rubber is quite good. Added the Altec Lansing part.

altec lansing ahs 515 cord repair

Headphone cord repair
My headphone has been repaired before in this previous blog post. Now the wire insulation is fraying right after the volume control.







Since the volume control is useless anyway, I opted to cut it out and re attach the wire. Step 1 is to knot the wires together, remove the insulation, and splay out the wires.


Next step is to Identify which wire goes to which. Fortunately, the mic cable only has 2 wires and the while speaker cable has 3 so there's no mixing them up. And the wires are color coded with what looks like varnish. It also serves as insulation.

It was a simple matter to tin the ends of the wires and solder them together. After this, I checked the headset on my PC. I used the audio driver's settings to check if both left and right channels were working.


Next, carefully cover the blobs of solder with electrical tape. I ended up using 3 layers in total.

Last step. I added an ID clip so I can clip the cord or cable to my shirt. This way the cord isn't dragging my head down via gravity.



OK that's it. Instead of buying a new pair of headphones, I just repaired mine. Saved me some money.

Lenovo Ideapad z470 Review - Part 4: hard drive benchmarks

< Back to part 3: 3d benchmarks

OK welcome to part 3 of my review. Hard drive benchmarks. I'm limiting it to synthetic benchmarks. We are comparing my desktop's hard drive, a WDC black 1 terabyte model WDC WD1002FAEX-00Y9A0 with the laptop's 750 gig WDC drive model WDC WD7500BPVT-24HXZT1.

For all the results, the first result or picture will be the desktop's hard drive, followed by the laptop.



1. Passmark performance test 7 build 1025 (Disk test only, copied from part 2 of the review)

  • desktop: disk = 735.6
  • laptop : disk = 623.5


2. Atto disk benchmark v 2.46








3. Crystal disk mark 64 bit v 3.0.1

Well pretty much all the tests show the desktop's HD to be faster, but they are quite close. Perfectly acceptable performance for a 2.5 vs 3.5 hard drive.

OK that's it. I'm planning a part 5: wifi file transfer benchmarks

lenovo z470 magnetized spots

magnetized spots

In response to a comment made in my lenovo z470 review, there was a coment about magnetized spots. Using a paperclip I have confirmed that yes there are magnetized spots. I could find 3, all shown as red on the pic above.

Without opening my laptop I really can't tell why there are magenets there. Its far away from the speakers and there are no obvious motors there. Any fan should have shielded magnets.

This probably poses no hazard since magnetic media like floppy discs and cassette tapes are rare these days.
