I have been using Waze for a couple of years and I turn it on for the same route to get my daughter to school in the morning and back home through traffic.

Recently, their routing algorithm has gotten so bad that I am on the verge of discarding it and probably try HERE maps.

The issues are

1) There was a railroad removal which block the road for several weeks. Waze didn't detect it and I arrived about 15 minutes later. I went home and tried to edit the map and to my surprise, I couldn't do it now whereas I was able to edit the maps once upon a time.

2) Recently, it has routed me to another supposed faster route to my daughter's school. I took that route once and we were late for school. From then on, I took the route which I am familiar with (which incidentally was what Waze had always been showing me till recently) and I keep seeing the ETA dropping. The ETA for the my regular route is about 5 minutes faster than the new Waze suggested route which is about 35 minutes

Not necessary. Though it is quoted "an umbrella costs the company 60 yuan ($8.82 USD) each to replace"

It doesn't mean they are going to replace it. The 60 yuan probably factor in cost like manpower etc rather than just the cost of the umbrella.

So like some of the readers pointed out, it could possibly be a good way to sell umbrellas whilst crying out wolf that they are losing money as a way to prevent copycats

Norton Utilities 8.0 and Norton Commander.

I loved the DiskEditor which enabled me to recover lost files by manipulating the FAT table, hack byte codes to bypass copy protection in the days when copy protection was done by reading in bad sectors in floppy disks.

Norton Commander for the ease of use to navigate file system in DOS days. I use TotalCommander now which is the best $40 I ever spent.

Poltergeist Room problem.

Back in the CRT monitor days, I was working for a computer repair company. There was this particular client (in the defence industry) who had monitors that started flickering and having a greenish hue at its sides after a week.

Every week, we had to go to his office to swap the monitors and bring the faulty ones back to recalibrate (it was costly, but hey, its a Defence contract and those pay big bucks)

It didn't matter whether the monitor was brand new or recalibrate ones, it just started flickering and had greenish hue after a week, and it only happened in that room. Other monitors outside that room and in other levels were fine, thus the room was dubbed the Poltergeist Room (as they blamed spirits for messing with it).

One day after the monitor exchange, I returned to the office and my supervisor queried me as to why I didn't reply to his multiple pages (we were using pagers back then). I realised I was in the Poltergeist Room when the pages were sent and therefore did not receive any page. It then dawned on me, "Could it be some electro magnetic interference from another level directly above or below that was playing havoc".

I went back to the client the next day to tell him what I thought and he (being electronics trained) realised that above him was a defence lab carrying out EMF experiments, which could have caused the monitor problems. He got to work to build a simple Faraday cage to prevent EMF from getting to the monitor. Since then, the monitors worked perfectly.

Peter Norton was my hero way back in the late 80's to early 90's.

I remember the first time I used Unerase to recover a deleted file and was fascinated by it. Then I discovered DiskEdit and began poking around in the FAT system and found out more about how DOS actually deletes a file. It actually marks the first character with a ?. Thus started my hacking days.

Then I used DiskEdit to bypass copy protection hacking the byte codes.

DiskEdit rescued me again when I switch to DR-DOS, set passwords on my files and forgot the passwords (fwiw, it was just setting the next dozen or so bytes after the file name in the FAT to zero)

Such memomories, DiskEdit and SideKick were my two must have utilities in the days of DOS

I can empathize with you. Back in 2009, I created a call filtering app for Blackberry which had the ability to determine if a call is urgent based on the frequency of the incoming call and to block the call if it was not urgent.

Guess what, in 2012, Apple put in an uncannily similar feature called "Repeated Call" in iOS 6

I was one of those who flipped from using Netscape to IE. I was using Netscape since 2.0 days. Comparing Netscape 3.0 to IE 3.0, Netscape won handsdown. It had far more features than IE 3.0 and was fast, responsive and easy to use.

Then came Netscape 4.0 and IE 4.0. This was were Netscape failed horribly.

Netscape 4.0 Communicator was slow and buggy and crashed often. When Netscape 4.0 Navigator crashed, it brought down the entire suite (Email client, Web Composer) along with it.

IE 4.0 on the other hand was really slick, stable and cool. It loaded up faster and rendered the pages faster (bear in mind those were the days of dialup).

It didn't matter that IE 4.0 was bundled into the OS. I was using Win 95 and I downloaded and installed IE 4.0 because I loved it.

To me, it wasn't the bundling of IE 4.0 into the OS that killed Netscape, it was just that Netscape 4.0 sucked compared to IE 4.0

After IE 4.0, I discovered Opera and have been using it since.

This is just beautiful. Practical application of maths. I would love to get my hands on one of these when it is done.

Glad that he has a patent for that. He should be justly rewarded for coming out with this road safety feature.

To those that believe that there is prior art, do note that the patent granted is for "Wide angle substantially non-distorting mirror". It is not just any curve mirror, it is unlike normal curve mirror which distorts the image, from the picture, you can see that there doesn't appear to be any distortion, which is what makes his mirror unique

Do you have links which says that "a computer in every home" is Jobs' vision? Google search throws up Bill Gates. There is even a plaque for it http://www.flickr.com/photos/mwichary/2184937614/

Though I believe that there are others who should also be remembered, but I am of the opinion that rightly or wrongly history will remember and associate Gates with computers much like Edison is to lightbulbs, Wright is to planes and Bell is to telephones (this is what kids are still being taught)
