How To Disable Secure Boot In Windows 8.1 In Acer Laptops

How To Disable Secure Boot In Windows 8.1 In Acer Laptops

I have already written about disabling secure boot in Windows 8.1 when I was using a Dell laptop. A number of people mentioned in comments that for them the option to disable secure boot was greyed out in UEFI settings. They simply could not disable the secure boot for the reason that the option was available to them.

I did not face this issue until I bought this new Acer R13 ultrabook. It comes with Windows 8.1 pre-installed and of course it has UEFI instead of the legacy BIOS system. In order to dual boot Windows 8.1 with dual boot, I wanted to disable UEFI secure boot first. And when I checked in to UEFI settings under Security tab, I found that the option to disable secure boot was grey. Moving the arrow key up and down to select this option was futile.

In this article, we shall see how can we disable UEFI secure boot for Acer laptops (and perhaps systems from other manufacturers).

Olá iPANEMA, Adeus Havaianas? Part 3

After four years of experience with Ipanema flip-flops in lieu of Havaianas, the verdict is in.

Ipanemas are better than Havaianas in every conceivable way. Stronger material. Better looking. More precises detailing. Better quality control.

Not one strap on any pair of Ipanemas I have bought has ever broken before the soles wore out from walking on concrete.

The same cannot be said of Havaianas. Several pairs had straps break on me after wearing them for merely a month or two.

Bottom line?

Olá iPANEMA, Adeus Havaianas.

Havaianas are junk. Ipanemas on the other hand, are a quality product.

If you live in Taipei, here is where to shop.

Beach Refuge: recycled containers with ocean views

Standard 20 and 40 foot long ISO shipping containers have been often used as emergency housing in disaster areas.

Unfortunately those charged with using shipping containers for this purpose, even in the "First World," are usually tone deaf and color blind when it comes to design. The results can be dismal indeed.

Typical Poorly Designed Emergency Housing:
How NOT to design a Shipping Container House!

My own preliminary study of shipping container housing design has taught me that three design features are essential for shipping container houses:

1. The shipping container house must be elevated above the surrounding grade level, at knee height or above
2. The shipping container house must include a generous elevated outdoor deck, that is both visible and accessible from within the house 
3. The outdoor deck must be covered by a roof or a canopy

The shipping container beach refuge shown below, by contrast, was designed by talented Chilean architect Pablo Errazuriz. It has all essential three design features mentioned above, and meticulous attention to architectural design. The result is impressive. It and other architect designed shipping container homes, suggest the unrealized potential in shipping container architecture.

Several T8 fluorescent tube lighting ideas found on the Internet that could be incorporated into an industrial chic interior.

These would obviously require remote ballasts. Treated properly however, the ballasts could be turned into visual assets.

iPANEMA Men's Flip Flops on display in store in Brazil

The iPANEMA flip flops I purchased online have just arrived in the mail.

As it turns out, I was right. iPANEMA flip flops are indeed manufactured to a higher degree of precision than Havaianas.

I know. The term "precision" is probably overkill. After all, we are talking about flip flops, not lathes or milling machines. They are hardly "precision" items. Nevertheless, the differences are highly visible, and do in fact matter.

iPANEMA soles appear to be injection molded. As a result, the edges of the soles are slightly radiused and smooth.

Havaianas soles appear to be stamped out of rubber sheets, the way cookies are cut out of a flat sheet of cookie dough with a cookie cutter. As a result, the edges of Havaianas soles are slightly rough. That's no biggie.

Cookie Cutter

What's worse is that they are often visibly warped. They were probably not allowed to cool off properly during the manufacturing process. The iPANEMA Flag flip flops I just received in the mail have perfectly flat soles. But the Havaianas TOP flip flops I recently passed on in two Taipei chains had obviously warped soles.

iPANEMA flip flops have another advantage over Havaianas. Their straps are slightly shorter and tighter-fitting than those on Havaianas. They were probably designed for slightly skinnier feet, such as mine. That means iPANEMA flip flops will stay on my feet more securely than Havaianas.

Some critics of flip flops insist they are harmful because the wearer will unconsciously curl his or her toes to keep them from falling off. They say this causes muscle strain. I doubt that the strain is all that great. But even if these critics are correct, flip flops with slightly shorter, tighter-fitting straps would not have this problem.

Now all that remains is to see how durable iPANEMAs are. If they last at two years before a strap breaks, I will not complain. I wear flip flops everywhere, almost all year round. By then I will have gotten plenty of wear out of them. 

iPANEMA flip flops share one trait with Havaianas. They have nearly identically shaped, highly asymmetrical footbeds. The toe region of the flip flop is very obviously skewed to one side, in the direction of the big toe. That is how it should be. Because that is the way most peoples' feet are shaped. When Havaianas and iPANEMA designed their flip flops, they clearly studied human feet before arriving at these highly asymmetrical footbeds. What's interesting is that this not only works better, it also looks better.

Note the pronounced left/right asymmetry in the toe region? That is how it should be. 

This highly asymmetrical footbed shape distinguishes both iPANEMA and Havaianas flip flops from the ultra cheap foam rubber zoris sold in drug stores in the US during the 1950s, and the somewhat higher quality current reincarnations sold by Old Navy.

Old Navy Men's New Classic Flip-Flops White 
Note the misguided attempt to reduce left/right asymmetry in the toe region? That is a mistake. 

Those were "designed," if that is the right word, by people who allowed their preconceptions about the shape of the human foot to trump reality. They unconsciously attempted to impose an artificial left/right symmetry in the toe region. I'll be the first to acknowledge that the difference is subtle. Non-designers probably have a hard time seeing it even after it is pointed out. But the attempt to reduce asymmetry and to impose artificial symmetry is wrong. The human foot is not symmetrical. It is decidedly asymmetrical.

7-11 vs. Starbucks

Starbucks Taiwan "Phinney" Stainless Steel Tumbler - 900 NT
(Sold for $19.95 in the US)
Available in white

7-11 Taiwan "City Cafe" Stainless Steel Tumbler - 399 NT
(354 NT if you deduct the 45 NT Medium Latte included free with each purchase)
Available in Trendy Silver or Simple White

Notice how the tumblers are nearly identical? They were almost certainly supplied by the same OEM manufacturer on mainland China. 

If you deduct the price of the medium latte that comes free with the tumbler, the cost is only 354 NT. That means a savings of 546 NT over a nearly identical tumbler from Starbucks.

I bought one each of the 7-11 City Cafe tumblers. One in "Trendy Silver," or brushed stainless steel, and the other in "Simple White," or white enamel. They're very well made. The tolerances are close. The detailing is precise. The slight taper keeps the tumbler from slipping in case one's hand is wet or oily. Most importantly, the lip has a large radius curve where one's mouth touches the tumbler.

Note the rounded lip on this Starbucks tumbler? Click on the photo. The 7-11 tumbler has the same rounded lip. That is how it should be.

Many tumblers/vacuum bottles on the Taiwan market have an almost raw sheet metal edge at the lip. Click on the photo. This is not how it should be. Frankly I don't understand how anyone could have signed off on such a design and allowed it to go into production.

Olá iPANEMA, Adeus Havaianas?

I've been wearing Havaianas flip flops for over a decade, long before they became all the rage here on Taiwan. I obtained them by mail order from overseas, before Havaianas established retail outlets here. Before that I wore traditional Japanese zoris, the inspiration for flip flops. I avoided conventional shoes whenever I could.


Because the human foot was never meant to be stuffed into a stiff, airless enclosure that causes bunions and athlete's foot. As podiatrists will tell you, bunions are completely unknown in cultures that do not wear shoes. Modern man's foot problems are the result of wearing conventional shoes.

Traditional Japanese Zoris

In order to expand its market, and sell more of its product, Havaianas waged a wildly successful public relations campaign to transform the humble flip flop into a chic, must have fashion item. It was admittedly promoting its own commercial interests. But in doing so it did something good. It made wearing more healthful footwear more socially acceptable, or at least less socially unacceptable. For this it deserves real credit.

But Havaianas quality control has slipped noticeably over the past few years. Brand new rubber soles emerge from the box badly warped and never flatten out. They were probably not cured properly during the molding stage. Also, the rubber straps often break after less than a year of wear. Other wearers have encountered the same problem, so it's not just my imagination.

Flip flops are consumables. No one expects them to last forever. A couple of years of life is reasonable. But mere months before a strap breaks is ridiculous. The sole should be pretty much worn out by the time a strap breaks. The phenomenon has me wondering whether Havaianas isn't deliberately forcing consumers to buy replacements merely to increase sales. The problem has gotten so bad, I might never purchase another pair of Havaianas flip flops again.

So what's the solution?

For me it is to forgo "brand loyalty" and switch brands. Two days ago I put in an order for several pairs of iPANEMA flip flops, which are also made in Brazil. If appearances are any indication, they are manufactured to a higher degree of precision than Havaianas. They are also made from different raw materials. Havaianas are made of rubber. iPANEMAs are made of PVC.

iPANEMA Flag Men's Flip Flops Navy/White

Havianas claims that the rubber used in its Havaianas flip flops, which is natural, has numerous advantages over PVC, which is man made. Do their arguments hold water? I'm not sure.

iPANEMA claims that MELFLEX, the flexible PVC used in its iPANEMA flip flops, is recyclable and environmentally friendly. It is non-toxic and hypo-allergenic. It contains no heavy metals, but is instead made with calcium zinc mineral salts, which are harmless to human beings.

Whatever the merits of their respective arguments, it is my understanding that PVC has significantly greater tensile strength than rubber. Will the straps on iPANEMAs be less prone to premature breakage than those on Havaianas? I hope so. If they are, then it will be "Olá iPANEMA, Adeus Havaianas" -- Portuguese for "Hello iPANEMA, goodbye Havaianas." I will know better in about a week, when they arrive in the mail.

I was surprised to learn that in 2010 iPANEMA sold 250 million pairs worldwide, beating out Havaianas by 80 million pairs. Given the depressing decline in Havaianas' quality control, perhaps I shouldn't have been.

iPANEMA is a much younger company than Havaianas. It was only established in 2001. Havaianas by contrast has been around since 1962. But iPANEMA's parent company Grendene has been around since 1971, and based on sales volume, Grendene is one of the largest shoe companies in Brazil.

iPANEMA definitely has Havaianas in its sights. Havaianas really should do something about the problem. Like Rome, a brand cannot be built in a day. But it can be destroyed overnight. Just ask Lehmann Brothers.
