Is Storage Necessary For Renewable Energy?

mrflash818 Habits can adjust to when renewables are best (442 comments)

If peak PV power is mid-day, then do energy-intensive tasks mid-day, if there starts to be a significant amount of PV energy available.

Certainly some appliances, like clothes washers, dish washers, and clothes dryers could be programmed and scheduled for mid-day use, while you were at work.

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

mrflash818 Learn fundamentals, and a hot button (637 comments)

One of my favorite Computer Science instructors said to us: Learn the fundamentals, and a hot button.

A hot button is the 'new cool thing' that everyone is asking for.

The fundamentals are, well, the fundamentals.

So, when I went to school to work on my Bachelor's, we used ADA, c, c++, x86 assembly. ADA was for the "intro to computer science", clang was for many, I chose to use c++ for compiler class. x86 assembly was for assembly language programming.

Back then Java was the new thing, so I made sure to take Java as an elective.

So for YOU, figure out what is hot, learn it, but also learn your fundamentals. Knowing how to allocate, use, and return system resources is a fundamental. That fundamental is used for working with Files, Memory, Databases. I would dare day that also learning to work with exception handling (c++/java) is a good fundamental. If you think 'old school' programming is an interest, then being comfortable with clang pointers would be good as well.

Verizon Throttles Data To "Provide Incentive To Limit Usage"

mrflash818 I would rather pay for a set bandwidth cap (316 comments)

I would rather pay for a set bandwidth, unlimited usage at that bandwidth level, than "faster, but you get charged penalties for exceeding your monthly cap."

My DSL used to be unlimited, _real_ unlimited, and I miss that type of service/honesty/product.

c/c++, vi/emacs, make, ddd.

Lots of good years of use, likely many more years of usefulness, too.

Math, Programming, and Language Learning

mrflash818 Never had to use any college math on the job (241 comments)

Knowing the concepts may have helped for some work I have done, but, I have never used any advanced math for paid programming.

Five years as a J2EE developer: zero use of any advanced math for work projects.

Numerical methods (using Fortran) was just in school.
Calculus, linear algebra, and such: just in school.

Big-O notation, to pick algorithms and STL objects, sure, but probably doesn't count as 'math' for this article.

Since only a fraction of Computer Science graduates will work at a science shop (JPL, etc), I think some of the math requirements are a bit unfair. Perhaps I am just a low-range "Forrest Gump" programmer, but my personal experience was the actual math was burdensome to do to work towards a Computer Science degree.

The Security Industry Is Failing Miserably At Fixing Underlying Dangers

mrflash818 Cash is King (205 comments)

Thanks to all of this, and the NSA/GCHQ Orwellian Internet world, I no longer do any commerce online.

Online for me now is chatting, posting, blogging, /., emailing, sharing source code.

I no longer do any purchases, or access any online systems that deal with money (banks, credit unions, etc), via the Internet.
Even in the real world, I try to only get my cash via walk-up to a bank teller. No more ATM use. No more credit card/debit card use, if I can at all help it.

Is trying to do a cash-only lifestyle a total time suck, and inconvenient? Yep.

I am certain I can still be a victim, but I am doing what little I can to not be an easier target.

Workaholism In America Is Hurting the Economy

I do not do it because I want to as a direct desire.

I do it because I love my family, and they depend on my income, so I try to make sure, like running away from zombies and not being slowest..., that I am not the least productive worker, m'kay?

EFF To Unveil Open Wireless Router For Open Wireless Movement

mrflash818 I am fine with sharing as long as QoS and firewall (184 comments)

I am fine with sharing my network and wi-fi bandwidth, as long as two conditions are met

1. That the open public Wi-Fi is QoS, so it cannot max out my connection, and starve my own private WPA2/AES wi-fi of needed bandwidth (So yes, I will share, but am gonna be a bit frugal on how much I am willing to share. Don't want someone streaming HD movies for free, but email and regular web browsing bandwidth is OK.)

2. That the open Wi-Fi is fully firewalled and separate from my own home network.

The Supreme Court Doesn't Understand Software

mrflash818 Software should not be patentable (263 comments)

Software are just instructions that run on a processor.

Will 7nm and 5nm CPU Process Tech Really Happen?

mrflash818 Will it last with 10yrs of continuous use? (142 comments)

I worry about the reliability with tinyer and tinyer CPU feature size. will those CPUs be doing, reliability-wise, 10yrs later?

When I buy something 'expensive', I expect it to last at least 10yrs, and CPUs are kinda expensive, to me.

(I still have an Athlon Thunderbird 700MHz Debian workstation that I use, for example, and it's still reliable.)

NRC Human Spaceflight Report Says NASA Strategy Can't Get Humans To Mars

mrflash818 Currently there are too many distractions (206 comments)

I do not think humans will get into expanding our civilization past Earth's atmosphere until there is a single global government. Currently the nation-states divert too many resources against each other (arms, trade wars), that instead could be used into expanding us beyond Earth.

shell script to distribute files from 1 dir to many dirs

mrflash818 mrflash818 writes  |  more than 4 years ago

Just a shell script I wrote to be able to distribute files in one file to many directories.
Created it because my one directory of digital images was getting too big, such that it was slowing down image viewer startup.
#! /bin/bash

# distribte (by using mv)files from a source directory
# to collection of target directories (by using a for loop)
# ...
if [ "$#" -lt "3" ]
    echo " ... "

ARG_ARRAY=( "$@" )

unset ARG_ARRAY[0]
#for i in "${ARG_ARRAY[@]}"
# echo $i


# Get list of files to distribute
for i in $(ls $SOURCE_DIR)
    if [ -d "$SOURCE_DIR/$i" ]
    #distribute to the distination directories
    #echo "mv \"${SOURCE_DIR}/$i\" ${ARG_ARRAY[$AAL]}/."
    mv ${SOURCE_DIR}/$i ${ARG_ARRAY[$AAL]}/.
    AAL=$((AAL + 1))
    if [ $AAL -gt $ARG_ARRAY_LENGTH ]


sgvlug - january 2008 meeting - was great fun

mrflash818 mrflash818 writes  |  more than 6 years ago

Went to the SGVLUG general meeting last night.

Had a great presentation on WINE, the windows compatibility softare, running on a recent Ubuntu.

Then went to Burger Continental to pig out. Had a garlic chicken pita, salad bar, and chocolate cake with cherry ice cream and a Dr.Pepper.

3000 calorie nirvana.

Was great fun.


Debian PC back up after hardware failure

Yay to my fellow members of the sgvlug.

The power supply on my Debian PC failed a few months ago.

A sgvlug member donated a 400w ATX power supply this weekend. Installed it, and now my little workstation is back!

yayness - karma feels good sometimes.
