Ask Slashdot: "Real" Computer Scientists vs. Modern Curriculum?

marcomarrero Re:Not this again. (637 comments)

Even worse is that REP STOS executes a lot slower than corresponding code since Pentium. I agree X86 is horrendous, especially its crazy little-endian. I was unfortunate I already knew 6809 asm: SEX, STD U++, HCF (sign extend, halt and catch fire).

Microsoft Takes Down No-IP.com Domains

marcomarrero Re:In before (495 comments)

The coincidence is that DynDns stopped offering free service a while ago. Maybe Microsoft made them an offer they couldn't refuse...

Windows 9 To Win Over Windows 7 Users, Disables Start Screen For Desktop

marcomarrero Re:hmmmmm (681 comments)

Isn't supposed to be Windows 8.22 Step-up? (I wonder if anyone remembers upgrading from MS-DOS 6.0)

Endurance Experiment Writes One Petabyte To Six Consumer SSDs

marcomarrero Re:Intel - weird failure mode. (164 comments)

The 8MB problem is an Intel firmware bug (older, non-Sandforce controllers). If you don't care about your data, ATA "security erase" can make it usable again. I think I used the DOS-based hdderase, and after a few problems it went through. Intel's DOS-based flash idiotically ignores the SSD because it identifies itself as "BAD_CTX"...

Google Engineer: We Need More Web Programming Languages

marcomarrero Re:Why? (309 comments)

The only programming language available in all web browsers is Javascript, which is horrendously bad for large projects, even Google and Microsoft made languages that generate Javascript code (Dart, Typescript). Another problem is that Javascript code is plain text, offline apps entire code is easy to read (even after de-ofuscating).

Plugin? On iOS, Apple won't ever allow any plug-in that can run its own apps (everything must be from Apple store).

Intel Confronts a Big Mobile Challenge: Native Compatibility

marcomarrero Re:Fsck x86 (230 comments)

x86 survived because of price/performance caused by fierce competition (Intel, AMD, Cyrix, Rise, Centaur, etc.), and popularity of Windows/DOS. It was fun experiencing how x86 beat faster RISC CPUs (Alpha, PowerPC, Itanium) when there were builds of Windows NT.

Now, people are downgrading to ARM to use their low-power, low-performance portable toys (tablets, smartphones) running inferior operating systems. Sadly, Intel did an horrendous job with the Atom until 2-3 years ago, and Microsoft did even worse releasing the bloated Vista, which was awful for the now-dead netbook market.

Atoms are finally good enough, but still, the absurd 2GB RAM limit, and high power consumption (most Windows tablets can't charge from USB hub or PC) is still not good enough for Windows 8 (the real one, not RT).

And, please don't teach your kids x86 ASM. Modern C++ compilers generate good optimized code, runtime libraries are optimized. Besides, x86 code looks backwards, instruction set origins are from a 1970 terminal! (datapoint 2200), has endianness from hell, few registers, etc.

Ask Slashdot: Easy-To-Use Alternative To MS Access For a Charity's Database?

marcomarrero Re:How about Microsoft Access? (281 comments)

I agree, it might qualify for non-profit versions of Windows. If Access doesn't qualify, anyway the MS Access Runtime is free. It's the full MS Access, w/o menus or IDE, although all menu options are available from VBA. Access Runtime might work in Wine, but I don't think the EULA allows it.

Besides, porting can be impossible, Access is quite unique: VBA (functions can be called in forms, reports, and even from SQL), Eval() (self-executing code), reporting is unique, Win32 API calls, and, it can automate any other Office application.

Should Microsoft Give Kids Programmable Versions of Office?

marcomarrero Re:VBA ?!? (226 comments)

Learning kids to program using VBA is like learning to cycle using a pogo-stick.

...easy to use pogo stick commonly found in workplaces that can automate Excel, Word, Powerpoint and Access. I admit it's an awful programming language, but it's not that far away from PHP (Hack improves it), and Javascript (TypeScript, Dart).

Anyway, US schools have historically used technology as expensive educational toys, not for programming or other useful practical things. BASIC was barely taught in the 80's when it was built-in all micros/PCs, and most computer magazines included program listings, for example, Compute! and Family Computing.

Nvidia Announces 192-Core Tegra K1 Chips, Bets On Android

marcomarrero Re:"...powered by the 192-core NVIDIA Kepler GPU.. (128 comments)

I was misled too. The useless headline is using the same pointless info nVidia presented, because they can't use "CUDA cores".

The Desktop Is Dead, Long Live the Desktop!

marcomarrero Re:make my day... (453 comments)

I think the problem are the people using useless tablets as if they were PCs, and sadly, liking them... I bet it will take more than 5 years for Android and iOS tablets to become as powerful as your current gaming PC, maybe 5 more years to become as useful.

AMD Intentionally Added Artificial Limitations To Their HDMI Adapters

marcomarrero Re:Why do this? (256 comments)

I think you're right, and I also think sending audio through DVI is a ugly non-standard proprietary hack, so it's logical it only works with their adapters.

Why Apple Went 64-Bit With the iPhone 5s

marcomarrero Re:It's about jailbreaking. (512 comments)

I was guessing the 64-bit move was for Apple compete against desktops in the current BYOD trend... Microsoft is doing the exact opposite with Windows RT, especially with Intel power savings improvements in Haswell CPUs, and, resurrecting the neglected Atoms. I wonder is Apple was expecting the Surface Pro to do better. It's significantly more powerful than any Android or iPad tablet, has a great pen device, and... there's no Apple Mac tablet.

Ask Slashdot: Buying a Laptop That Doesn't Have Windows 8

marcomarrero Why not a desktop instead? (570 comments)

Why a main laptop? Get a cheap, slow, portable, disposable notebook / budget laptop, and build your own powerful desktop computer. College students get Windows Server 2K12 (or 2K8R2) 100% free (via Microsoft Dreamspark). I guess I'm too old to understand laptop obsession. I need at least two monitors, and a real keyboard / mouse to be productive. (I dearly miss IBM Model M keyboards). There's no reason not to use Win8, except compatibility (they did change some security stuff). There's Classic Shell, and, you can run WinRT apps. Anyway, the only way around the eternal idiotification of Shells (after NT 4), is to somewhat accept it. Even Linux users are tortured with new weird stuff too.

Lexmark To Exit Inkjet Printer Market

marcomarrero Re:Inkjets dont have to be so expensive... (228 comments)

It's an expensive advantage, most won't print 100% b/w text if the color ink cart is missing or empty, regardless if the black ink cart is full. I also found out inkjet printers require multiple attempts until they break into a million pieces.

Ask Slashdot: Understanding the SNES?

marcomarrero Re:Check out Byuu's stuff from BSNES. (157 comments)

I agree, I also recommend MAME and MESS, I don't know how well they emulate the SNES, but I think its source code is designed for preservation and documentation rather than performance.

Chevy Volt To Resume Production One Week Early Following Record Sales

marcomarrero Re:It still sucks. (443 comments)

No Civic coupes, but, two hatchbacks did 50 MPG, according to fueleconomy.gov
1994-95 Honda Civic HB VX (39 city, 50 highway)
1986-87 Honda Civic CRX HF (42 city, 51 highway)

It would be a miracle finding those with their original engines... '90's Civic engine swaps were simple, cheap, and performance was great with JDM DOHC engines like the ZC, B16A (> 160 hp), or B18C (> 200 hp).

'Retro Programming' Teaches Using 1980s Machines

marcomarrero Re:Does that make sense ? (426 comments)

I somewhat agree with you, it makes sense from an educational view and it's completely pointless to help find a job.

Unfortunately it's not the 80's, back then any good programmer could get a job. In these times, there's a lot of competition and incompetence out there. Employers will only hire anyone who matches all the keywords and does a good interview, regardless of talent, because they're desperate (or clueless).

For example, my hobbyist 8086 and 6809 ASM experience is completely ignored and pointless all the times I've applied for job positions in microcontroller / embedded system programming. My x86 code did everything at a hardware level except disk I/O, mouse, and LAN.

The Worst Apple Products of All Time

marcomarrero Re:No they have a good point about PPC (469 comments)

I disagree, the X86 was a really bad choice back then. Pentium didn't exist (released 1 year later), the 486 DX2 was released the same year. The PowerPC easily beat the 486, and because it's endian neutral, I bet 68K emulation would be too slow on P5.

The Pentium also destroyed the 486: the FPU was a lot faster, and it could execute two integer instructions at a time. Unfortunately most code wasn't P5 optimized and avoided the FPU (lots of 486SXs out there). Quake was probably the first app that ran well on a P-60, and unplayable in a DX4-100.
