Symbian, the Biggest Mobile OS No One Talks About

MattRog Re:It's a pain in the ass to develop for (423 comments)

To me, the biggest drawback is its popularity: the hardware is insanely fragmented. Want to write a Symbian app? Browse the device list http://www.symbian.org/devices

App developers have to support:
1) mix of touch and non touch screens
2) Insanely different display resolutions
3) Crazy list of hardware buttons (some have keyboards, some none, some have the 10 digit numeric, etc.)
4) Different form factors (clamshell, block, etc.)

Basically, writing a very good, elegant app that people WANT TO PAY FOR in Symbian is a disaster. Best to write for iOS and Android. Although both hardware platforms are fragmented they are not nearly as bad to deal with as Symbian. That, and there's a culture of "It's OK and normal to buy apps" (much more so on iOS than Android, of course) that doesn't appear to exist on other platforms (yet).

Dragging Telephone Numbers Into the Internet Age

MattRog Isn't this backwards? (239 comments)

Why, in this day and age, are we talking about NUMBERS? Do we address websites via IP address? No, we have DNS.

Why isn't there a DNS for phones? I pick a name, perhaps even something as simple and unique as MY EMAIL ADDRESS, and then anyone who knows my email address can contact me. Or, just like DNS, I can set up any number of unique names for various things (my-recruiters@gmail;) that point to some sort of numeric based phone.

You could even call it Phone Name System.

Intel Pulls SSD Firmware Day After Release

MattRog Not just Intel (125 comments)

Crucial's M225 (I own the 128GB version) 1711 firmware had significant bugs and was quickly yanked. In order to upgrade to the latest 1819 you have to downgrade back to 1571.

Seems as if most consumer SSD products are still a bit in the "beta" stage.

Google Finds DRAM Errors More Common Than Believed

MattRog Re:"RAID"-style system for RAM... (333 comments)

No, not really.

RAID-5 allows for disk failure via distributed block parity. ECC recovers single bit error.

The "Memory RAID" design should prevent a larger issue (multi-bit/DIMM failure/etc. that ECC cannot prevent) from taking the whole system out.

I would imagine that ECC memory would be used in conjunction with higher-level striping or mirroring to prevent and recover from both failures.

Google Finds DRAM Errors More Common Than Believed

MattRog "RAID"-style system for RAM... (333 comments)

RAM is dirt cheap and most server systems support significantly more RAM than most people bother to install. For critical systems, ECC works but that doesn't prevent everything (double bit errors etc.). Is it time for a Redundant Array of Inexpensive DIMMs? Many HA servers now support Memory Mirroring (aka RAID-1 http://www.rackaid.com/resources/rackaid-blog/server-dysfunction/memory_mirroring_to_the_rescue/) but should there be more research into different RAID levels for memory (RAID5-6, 10, etc?)

No worries -- the concept is right :)

Null References, the Billion Dollar Mistake

MattRog Re:20 second explanation (612 comments)

"Obviously the best way of accomplishing such a database is to denormalize any value that might be null"

That's normalizing -- the table in this example is de-normalized

New SQL Injection Attack Fuses Malware, Phishing

MattRog Wouldn't work on ASE... (202 comments)

for a few reasons, the biggest of which is that no one in their right mind would use ASE on Windows to begin with (thus probably wouldn't be running IIS)...

But seriously, ASE doesn't use xtype in such a way, nor do (most) of the (x)type ID's match up to meaningful ASE datatypes (the TEXT type IDs do match).

Anyway, ASE admins need not fear any more than Oracle or MySQL or DB2 or PostgreSQL or $DB admins; this script would have to be modified to run successfully on ASE.

Server Relocation?

MattRog MattRog writes  |  more than 5 years ago

MattRog writes "We're relocating a rack or two of servers from our office's datacenter (Lexington, KY) to a co-loc facility about 100 miles away in Cincinnati, OH. For reasons which should be obvious (insurance, insanity, etc.), we are looking for a dedicated hardware relocation provider to disassemble, crate, and ship to Cincy. The co-loc facility will do the uncrating and re-racking.

Googling provides a TON of "AWESOME" providers, but has anyone worked with a provider to do this? Is there a place that rates this type of moving provider (http://www.movingscam.com/forum/ is a great resource, but doesn't target this sort of business relocation service)?

Thanks!"

Phosphorus shortage ahead?

MattRog MattRog writes  |  more than 6 years ago

MattRog (527508) writes "We've heard of peak oil. We've even discussed peak helium. Now we are facing peak phosphorus!

According to scientists, due to increased demand from sources such as biofuels (not exactly "renewable" if the inputs aren't!), we will exhaust our supply of non-renewable phosphorus in 50 to 130 years. If you didn't know, phosphorus is one of three major nutrients for plant growth: nitrogen, phosphorus, and potassium. Without phosphorus it's tough to grow crops. As the USGS wrote, "There are no substitutes for phosphorus in agriculture."

The European Fertilizer Manufacturers Association has a similar analysis, with recommendations for recycling and better use of the element."
