PS: You may want to read up on "detox" - see this for a brief explanation. (quick google search for "unschool detox"
I'm not just shouting from a bridge - the type of education I discuss is often called "unschooling" or "child-led" education. It's radically different, and surprisingly effective. It's public school turned 180 degrees - and results are simply incredible.
So, are you saying that you aren't willing to learn the things you need to learn?
Children are PEOPLE lacking in experience. Give them the power, give them the appreciation for their role in life, give them the choice to take part in it, and they will stand up to it!
It's a foreign concept that's hard to grasp in today's top-down, authoritarian culture, but it's real, and it really works!
When a student has made a goal, eg: 'I want to be a microbiologist" or 'I want to be a naturalist', or 'I want to be a hair stylist', then the conversation easily migrates to 'what do you need to do to get there?'.
And this is where the student WILLINGLY does homework, WILLINGLY learns calculus, where YEARS of education get done in a matter of weeks, depending on the goal.
Are you really so incapable that you are unwilling to learn what you need to?
I think you missed the whole point. So, I'll try again:
I'd say you're part of the problem.
You're entitled to your opinion. What experience do you personally base it on?
You can't assume a child is going to be willing to learn things they need to learn.
Because... why is that? When you want to do something, (say, go bowling) can you not be trusted to find out how to bowl?
Provide the need, and the kids will step up to the plate!
"In my experience, children who learn math when they want to..." Really? And when have you ever seen a child want to do long division, let alone calculus.
It's not the calculus that the kids want to learn. It's the thing they'll use calculus for. Knowledge is a tool to solve a problem. When a kid decides to solve X, and X involves calculus, you'd do best to just get out of the way. I've seen this time and time again.
(Yes, my own 2 oldest children, age 16, now honors students in college, furiously working their way towards microbiology, have indeed done large amounts of Mathematics, entirely of their own accord!)
"No, teaching irrelevant information at schools is ruining the kids! " and "And of course, that fancy, embossed paper is proof that there is nothing more to learn than what you know, right? " And just how do you judge irrelevence?
I won't pretend to judge relevance for YOU. YOU determine what's relevant, and what's not. (see above) The fact that the kids have determined its irrelevance is the problem.
Can you by chance claim you've gone through an accredited university's teaching program?
Since my basic platform is that the educational system is a miserable failure, why would I want to be accredited in it? I *might* consider some collegiate work (where education is much more optional and "student led", but the elementary grades are just the pits)
I have years of experience with education, including my own children. I've talked to large numbers of other parents through organzations such as the Homeschool Association of California My profession is in the educational area. The difference between a classroom-based child and a comparable homeschooled one at 16, 18, or 21 is stark.
Have you read research material on how kids best learn? Have you studied the best way to teach children for years? No? Then you're not qualified to tell us how to best teach anyone but your own children.
I can provide *REAMS* of such material, if you are actually interested. There are thousands of websites a mere Google search away. As I've stated above, I've studied and worked in the educational sector with teachers and parents for years. And it's clear to me that in most cases, *nobody* is a better expert on children than their parents.
"No, they are simply an acknowledgement that the education system is *failing* to produce children educated to meet today's job requirements." While some alternative schools do seem to be doing a good job, the majority of homeschooling and "alternative" schools seem to be religious people sick and tired of learning science and not biblical "truth".
There are Christian homeschoolers, as there are all kinds of Christians, but (in Northern California) I've seen the most traction for homeschoolers and alternative education in the nonreligeous crowds, typically, squarely in the middle class. Parents (like me) who want something better for their kids.
Public education is stuck in a rut. The pot needs a good stirring. If we can provide several alternative education strategies to all income levels, then we can perform studies that help us identify which method really works.
Dogmatically supporting a system because "it's always been done this way" is just stupid, especially when there's every reason to believe that there is not only a better way, but lots of them!
Funny, as a father of successful, home-schooled kids, I see solutions 180 degrees divergent from yours.
Learning is INTRINSIC to humanity. Not only is it not difficult to educate, it's actually AUTOMATIC if we'd just get out of the !@#@! way! Children are NATURALLY curious! Why do we spend 12 YEARS teaching our children that their "curiousity is irrelevant, shuddup and do the odd problem set on page 122"?
In my experience, children who learn math when they want to, and they're good and ready, will digest YEARS of material in a matter of days or weeks. It's a matter of trusting them. We just have to provide the understanding and the materials when the kids are good and ready for it.
The dereanged idea that it has to have meaning, relevance, etc., or it is worthless is ruining schools.
No, teaching irrelevant information at schools is ruining the kids! If the kids figure there's no point, you're just setting yourself up for an uphill battle, which accounts for much of the failure in public education. Humankind is WIRED to be curious about things that are IMPORTANT. (Heh, look at the tagline up above: "Stuff that matters" would YOU be interested if it said "Stuff that's irrelevant"?) By your logic, teaching children about proper use of buggywhips should never be questioned by the kids being taught!
Part of the process of education is evaluating the relative importance of the experience so you know what to ignore.
alternative learning styles, etc., are ruining basic instruction.
No, they are simply an acknowledgement that the education system is *failing* to produce children educated to meet today's job requirements.
Classroom based education is a system whereby naturally curious, intelligent children are forced to sit in a boring classroom, and forced to stand in line, in preparation for a mundane manufacturing job that won't be there when the children graduate.
Today's workforce requires flexibility and creative thought, not mind-numbed automatons. Beating them with lines, artificial schedules, algorithms, and pointless history dates will not result in creative thought and problem-solving. Having them learn by doing, by participating, and learning where data (which is now a commodity, see Wikipedia for an example) needed to solve a problem can be found.
The rise of independent study, charter schools, and other "alternative" education methods are society's response to the dysmal, dysfunctional failure that is classroom-based public education.
(by the way, I have an MA in Ed. Technology)
And of course, that fancy, embossed paper is proof that there is nothing more to learn than what you know, right? If you aren't too pompous and ossified, you might try checking out some other methods that have clearly proven to work.
The solution is out there, and in my book, you're part of the problem.
A new site's coming, and it seems to be decent... technocrat.net
It's slash-based, seems to have decent content, and you can still get a UID small enough to remember if you register. It's still no match for slashdot in terms of sheer volume, but...
That's not *entirely* true. A turbocharger uses the power from the waste gasses(exhaust) to drive the turbine that then adds boost to the air/fuel mix. So in that sense, the gasoline is used twice;)
Except,that this isn't entirely true, either. A turbocharger uses the difference in pressure from the exhaust of the motor and the outside air. This pressure comes from someplace, and in this case, it's the intake and compression strokes of the motor. If the energy consumed by a turbocharger wasn't pumped back into the intake of the motor, the added drag would kill the motor immediately.
Most of this energy cost is offset, however, by the fact that the turbocharger increases the pressure on the intake. Thus, a turbocharter (quite literally) consumes 90% of the increased pressure to perform its task.
In short, the turbocharger almost equalizes itself, but in the process, leaves an extra 10% which, combined with the more efficient burning of gasoline at higher pressures, is what gives the turbocharged engine that extra kick.
It's *very* hard on engine parts, which is why you can't just bolt on a turbocharger to any old existing motor and expect it to last very long.
Those pesky laws of thermodynamics! There ain't no free lunch, you know...
Now if antimatter becomes a common battery source (say SUV's have 1 millionth of a gram to make it run for the week), how hard would it be to make the ULTIMATE terrorist act?
Technology advances at the erosion of our classic freedoms.
In 1700, the most powerful weapon available was a rifle, which could shoot 1 shot ever 30 seconds or so, and the check against that kind of power was generally immobility (Horse?) and other people with firearms.
However, as time goes by, and technology advances, the tools become ever more powerful, and the controls in place to prevent catastrophe become ever more intrusive.
Personal privacy and personal freedom lose as we gain personal power. We're OK with it! Imagine the intrusion upon your privacy when people all around the world can contact you instantly in your living room! (the telephone)
It's a trend ongoing for 2 hundred years, and it's not likely to stop soon. What kind of controls will have to be in place to support the widespread use of antimatter for energy?
It's like asking "What's better: A semi-truck or a Corvette?" to which the answer is really a question. ("What are you doing?")
If you need to move tons of goods, a 'vette is going to do you very little good. If you want to impress the neighbors, compensate for a little deficiency, and get somewhere fast, a semi is not the way to go.
Each license has it's advantages and disadvantages. Saying that license X is "better for the enterprise" is like saying that "vehicle N is better for the highway".
Doing what? What are you trying to do?
"The enterprise" might mean an aircraft parts manufacturer with a small team of in-house programmers writing internal apps. To these programmers, GPL vs BSD means squat. Who cares?
"The enterprise" might mean a small software company selling vertical solutions to a niche market. GPL vs BSD means lots.
"The enterprise" might mean a large company selling products that include some software, but are primarily hardware. GPL vs BSD means a little, but probably not too much, mostly the annoyance of posting some source code in some obscure (but legally compliant) subdomain of a large, multi-gigabyte website.
The article is a troll, and I'm biting. Dang nabbit!
1) We're a small software company, and we're *VERY* mobile. I joke that my office is my laptop, but it's not much of a joke. we can (and do) work almost anywhere we have power + 'net connection.
2) We need to have a common file store primarily for backups, but also so that we can share files and documents easily.
3) WebDAV is close. Windows support for WebDAV falls short of actually mounting the drive. (EG: with a drive letter) This creates lots of little headaches copying files, some programs won't open files directly from a DAV folder, etc...
4) I found a utility put out by Novell, a free download, called "NetDrive" that lets you mount a WebDAV share as a drive on the local system. Google for NetDrive
5) This, combined with Apache/WebDAV/Mod_SSL makes an easy, reliable, secure, mountable drive that mounts anywhere an HTTPS connection is allowed. (which almost *ALL* firewalls allow)
I'm not using LDAP authentication. There are only 5 of us, and we don't hire/fire all that often.
sometimes the most functional things are the most beautiful. Lamborghini, Ferrari, Aston-Martin, Rolls-Royce, Bentley, XB-70 Valkyrie, SR-71 Blackbird, Concorde. Very functional machines, designed to perform very different functions, for very different people. And all very beautiful.
Have you ever actually *seen* a Lamborghini? They look great on posters - but on the freeway, they look like a shoebox that's been stepped on.
If you'd have said "BMW Z4" or "Mazda Miata", then I'd be agreeing with the whole "very beautiful" thing. But a Lamborghini? It's sole claim to fame is the fact that after doing 0-60 in less time than a late-model Corvette, it can do it again (to 120 M.P.H.) in even LESS time...
But beautiful? Don't equate price tag with "beatiful", eh?
Our work on EROS has ceased, because we came to realize that there was important stuff we had missed. The first steps towards a successor, Coyotos, can be found at <a href="http://www.coyotos.org./">http://www.coyotos.org./</a> My hope is that some early version of Coyotos will be running quickly, as we aren't trying to do much fundamental research on the kernel architecture per se, but it's been slow going so far.
Irony is when I call 411 on my not-cheap SBC copper telephone line, in order to resolve an issue with the DSL circuit on said phone line, only to reach some guy in India, with a strong, almost unintelligible accent, made all the worse for having a craptacular VOIP telephone with insufficient bandwidth/latency to pull off a phone call that doesn't go something like this:
Me: There is a routing problem with the DSL circuits, and my two branch offices won't connect with each other.
Him: Diz yoo tly to rabute the marmen?
Me: I'm sorry, can you try again?
Him: Dickt do try to rownon the mfarfen?
Me: You know, I'm not making heads or tails of this - can you please try again?
Him: Did joo tly to rnoof za noden?
Me: I think you are asking me if I tried to reboot the modem. Is that what you are asking me?
Him: Ysh
Me: Yes. I also rebooted both computers, and the hub and router. I still have the same problem...
(BTW: The above conversation went on for some 20 minutes, before "Him" told me that the problem was not on his end, and to contact our "Network Administrator". After very clearly(!) telling him that's who I was, and the problem was NOT ON MY END and could I PLEASE TALK TO SOMEBODY WHO COULD HELP ME, I was forwarded to somebody with a clear phone line, who spoke English as a primary language, who, after about 3 minutes, said: "How's this?" and everything worked fine after that. I wish I was exaggerating)
This is necessary because mod_php runs scripts as the same user who started httpd, usually "nobody", so any files you want your PHP scripts to write to has to be world-writable. The problem would go away if mod_php could just run PHP scripts as their owners, instead of as the user running httpd!
There's an answer for this - Metux MPM and it allows Apache to run as any user that owns the site with minimal performance degredation. (Obviously, there is SOME degredation!)
Unlike SuPHP, which runs a separate process for each site hit, this runs separate apache child processes, each child behaving in much the same was as Apache would, anyway, only per UID rather than per server.
This results in more child processes hanging around, but providses good performance when a particular user's site gets hit hard.
It supports chroot jails. This is the feature for which I will *finally* move to Apache 2.0, once I complete my migration testing!
You've obviously never tried to write a program that communicates using TCP/IP over the net...
I've written quite a few. Everything from shell scripts/Expect and telnet, to ssh autologin with RSA keys, to TCP sockets managed in Perl or PHP. I manage a distributed, 20 GB database, with about 500 users, with TCP socket calls written in PHP-GTK. It's built so that each installation of my software checks for the most recent version, and auto-updates. Rolling out software updates to everybody literally takes just minutes!
No, I didn't write TCP wrappers - but I don't have to. I still maintain that the Internet works just *fine* but that software vendors will be spending the next 5-10 years coming to terms with what a global, broadband, frictionless digital network really requires.
I see many posts here about how we need to "mandate" this and "require" that and blah blah blah...
But the Internet, by design, is lasse faire! There is no "mandating" ANYTHING! Anybody can hook up to their neighbor, who hooks up to some guy across town, who is hooked up to a couple other folks...
The Internet is DECENTRALIZED and OPEN. The closest it gets to mandating anything is the much-disputed RBLs. I, for example, block all email from most Asian countries - nothing personal, but it sure drops the SPAM load with virtually no complaints. But, I can't mandate what the Chinese or Koreans do with their network - I can only mandate what they do with respect to MY networks.
The Internet is merely a commonly agreed upon set of standards for communications across disparate networks, and it's performing the task of connecting networks the world over with grace and flair.
Don't tell me that just because Windows systems get infected in 12 minutes, that the Internet is broken. Sorry. The Internet is working fantastically. It's Windows that's broken. It's not up to the task of functioning on a globally accessable network.
So far, every significant "problem" I've heard with the Internet hasn't been with the Internet, but with the systems at its fringes. SPAM. zombies. Worms. Viruses. Exploits. All are simply side effects of a "zero friction network" as espoused by the all-knowing Bill Gates in his 90's book, "The Road Ahead", combined with systems not able to cope with the ramifications.
Bill Gates, Larry Ellison, Scott McNealy, Linus Torvalds, and all the others are learning now what that truly means, and over the next decade or so, we'll see major advances in developing the kind of security needed to handle this frictionless network.
In short: the Internet is doing just fine, people! It's the systems hooked up to it that have problems!
Because that wouldn't look suspicious at all if they ever found it.
It's HIS stuff. HIS box. HIS wall. Having computers in the wall is not illegal (not sure, it may be against the building code in some areas, but it'd be a stretch)
What's to be suspicious of? I've considered putting one or two of my main (home-based) systems in an obscure cabinet (that looks like an Air Conditioner) in the cellar instead of out in public view, just to deter theft.
Also, you'd be doing drywall and paint work every time the stupid thing ate a disk.
That'd blow. I'd suggest the obscure cabinet in the cellar, first.
You're forgetting that the licensing is per developer. If it's hard to understand, just imaging not receiving a paycheck for one month. Now go and rethink your post.
That changes almost nothing. Remember the "years" part of my post. It's not atypical for such a programming framework to save much, much more than a month in a 2 year project, and then there's maintenance after the fact.
Sorry. If you think that $6600 is unreasonable, you are lacking in experience.
Depending on the economics of your business, it may be worth the money, but "very affordable" it ain't.
If you think $6600 to allow for the productive development of software on all three major platforms, simultaneously, is EXPENSIVE, you are lacking in experience.
$6600 is a midline wage for a single coder for one month. Any decent sized project goes on for YEARS, and usually involves at least 2-3 coders.
$6600 is a drop in the bucket if it saves even 5% of developer costs over the long haul! A single sale can pay WAY MORE than $6600 when you are talking about custom, vertical apps, and that sale might well be made on the back of "*nix/Mac/Win compatable"...
Really, it's only the great works of artistry that need to be retained and remained, sustained and maintained. Historically, it's interesting to catalogue art, but politics? The everyday communications that lead up to the horrible decisions that lead our politicians to make the mistake of the daily business? We want records of this?
Absolutely, yes!
History is often taught as "Charlamagne took over Constantinople in the year 12xx" as though military feats really mattered to the average Joe. But, the truth is, America was colonized by people who thought that, however bad it might be in a virgin land, it was BETTER than their lives in Europe.
One of the key failures in public education today is to communicate the understanding that history is comprised mostly of PEOPLE doing ORDINARY things in their time to make life better for themselves and their families. They loved, worked, got bored, and cracked jokes at the expense of their leaders, just like we do today.
History doesn't consist of battles, anymore than history consists of artworks. Capturing more detail in the average, everyday lives of people gives a much better understanding to the cultural norms, and the ideals to which people aspired.
The pyramids of ancient Egypt provide a clear, artistic monument to their culture, yet we have an only modest understanding of their day to day cultures. Similarly, we have Stonehenge as a clear monument to the grooved-ware people of the English isles, but almost NO understanding of who they were and what they felt was important. How much would a true historian give to understand the day-to-day culture of these mysterious "grooved-ware" people of ancient?
Those memos and IMs comprise that understand of people today.
IMHO, 9 times out of 10, knowing somebody will get you farther than another bullet point on a resume
Yeah. If you're any good, don't spend time in class, spend time getting to know people! Put in some volunteer time at the local school. Hit the streets - get in touch with businesspeople through your local Chamber of Commerce.
Getting the good stuff, where they like you, appreciate you, and thank you as they hand you your check comes down to who you know.
The good stuff comes over dinner between two executives, or on the golfing green, or in a Saturday afternoon phone call, as in "my tech guy is leaving next month, who do you know?".
If you can be the name that slips those lips, you're in for some good quality work!
When you have a good rapport with somebody with some clout, ask them who they know that might need your services! Be friendly, and offer them a 5% or 10% kickback so that they can feel good about refusing the money. (and will see how important they are to you!)
Most everybody loves to help out, if it costs them nothing.
What what you do is take put your ISP's mail server in your DNS records for SPF, since the ISP's mail server is obviously considered an authoritative host to relay for your domain(s). (tough, huh?)
PS: You might want to avoid casual use of profanity - swear words are "power" words and excessive use reduces their power to create an effect. The end result? They fail to add power to your words, and make you look like low-class scum, or at the very least, just a kid who hasn't figured this out, yet.
I mean, go for it if that's the effect you want to create, otherwise...

If you need to move tons of goods, a 'vette is going to do you very little good. If you want to impress the neighbors, compensate for a little deficiency, and get somewhere fast, a semi is not the way to go.
Each license has it's advantages and disadvantages. Saying that license X is "better for the enterprise" is like saying that "vehicle N is better for the highway".
Doing what? What are you trying to do?
"The enterprise" might mean an aircraft parts manufacturer with a small team of in-house programmers writing internal apps. To these programmers, GPL vs BSD means squat. Who cares?
"The enterprise" might mean a small software company selling vertical solutions to a niche market. GPL vs BSD means lots.
"The enterprise" might mean a large company selling products that include some software, but are primarily hardware. GPL vs BSD means a little, but probably not too much, mostly the annoyance of posting some source code in some obscure (but legally compliant) subdomain of a large, multi-gigabyte website.
The article is a troll, and I'm biting. Dang nabbit!
Here's the problem I had, and how I solved it:
1) We're a small software company, and we're *VERY* mobile. I joke that my office is my laptop, but it's not much of a joke. we can (and do) work almost anywhere we have power + 'net connection.
2) We need to have a common file store primarily for backups, but also so that we can share files and documents easily.
3) WebDAV is close. Windows support for WebDAV falls short of actually mounting the drive. (EG: with a drive letter) This creates lots of little headaches copying files, some programs won't open files directly from a DAV folder, etc...
4) I found a utility put out by Novell, a free download, called "NetDrive" that lets you mount a WebDAV share as a drive on the local system. Google for NetDrive
5) This, combined with Apache/WebDAV/Mod_SSL makes an easy, reliable, secure, mountable drive that mounts anywhere an HTTPS connection is allowed. (which almost *ALL* firewalls allow)
I'm not using LDAP authentication. There are only 5 of us, and we don't hire/fire all that often.
sometimes the most functional things are the most beautiful. Lamborghini, Ferrari, Aston-Martin, Rolls-Royce, Bentley, XB-70 Valkyrie, SR-71 Blackbird, Concorde. Very functional machines, designed to perform very different functions, for very different people. And all very beautiful.
Have you ever actually *seen* a Lamborghini? They look great on posters - but on the freeway, they look like a shoebox that's been stepped on.
If you'd have said "BMW Z4" or "Mazda Miata", then I'd be agreeing with the whole "very beautiful" thing. But a Lamborghini? It's sole claim to fame is the fact that after doing 0-60 in less time than a late-model Corvette, it can do it again (to 120 M.P.H.) in even LESS time...
But beautiful? Don't equate price tag with "beatiful", eh?
Secure, Convenient, Cheap.
Pick any two.
(General rule, but it does generally follow)
It seems to me that a tremendous amount of SPAM comes from Florida, USA! So, when will the US decide to sign a similar pact to deal with it?
Irony is when I call 411 on my not-cheap SBC copper telephone line, in order to resolve an issue with the DSL circuit on said phone line, only to reach some guy in India, with a strong, almost unintelligible accent, made all the worse for having a craptacular VOIP telephone with insufficient bandwidth/latency to pull off a phone call that doesn't go something like this:
Me: There is a routing problem with the DSL circuits, and my two branch offices won't connect with each other.
Him: Diz yoo tly to rabute the marmen?
Me: I'm sorry, can you try again?
Him: Dickt do try to rownon the mfarfen?
Me: You know, I'm not making heads or tails of this - can you please try again?
Him: Did joo tly to rnoof za noden?
Me: I think you are asking me if I tried to reboot the modem. Is that what you are asking me?
Him: Ysh
Me: Yes. I also rebooted both computers, and the hub and router. I still have the same problem...
(BTW: The above conversation went on for some 20 minutes, before "Him" told me that the problem was not on his end, and to contact our "Network Administrator". After very clearly(!) telling him that's who I was, and the problem was NOT ON MY END and could I PLEASE TALK TO SOMEBODY WHO COULD HELP ME, I was forwarded to somebody with a clear phone line, who spoke English as a primary language, who, after about 3 minutes, said: "How's this?" and everything worked fine after that. I wish I was exaggerating)
This is necessary because mod_php runs scripts as the same user who started httpd, usually "nobody", so any files you want your PHP scripts to write to has to be world-writable. The problem would go away if mod_php could just run PHP scripts as their owners, instead of as the user running httpd!
There's an answer for this - Metux MPM and it allows Apache to run as any user that owns the site with minimal performance degredation. (Obviously, there is SOME degredation!)
Unlike SuPHP, which runs a separate process for each site hit, this runs separate apache child processes, each child behaving in much the same was as Apache would, anyway, only per UID rather than per server.
This results in more child processes hanging around, but providses good performance when a particular user's site gets hit hard.
It supports chroot jails. This is the feature for which I will *finally* move to Apache 2.0, once I complete my migration testing!
Just the other day we were being told that the Internet was broken and needed replacing. Then, we find that it is growing very nicely, only to have this article confirm it...
I mean, is this where I toot my own horn and say: I told you so!!?!?
You've obviously never tried to write a program that communicates using TCP/IP over the net...
I've written quite a few. Everything from shell scripts/Expect and telnet, to ssh autologin with RSA keys, to TCP sockets managed in Perl or PHP. I manage a distributed, 20 GB database, with about 500 users, with TCP socket calls written in PHP-GTK. It's built so that each installation of my software checks for the most recent version, and auto-updates. Rolling out software updates to everybody literally takes just minutes!
No, I didn't write TCP wrappers - but I don't have to. I still maintain that the Internet works just *fine* but that software vendors will be spending the next 5-10 years coming to terms with what a global, broadband, frictionless digital network really requires.
Guys, guys GUYS!
I see many posts here about how we need to "mandate" this and "require" that and blah blah blah...
But the Internet, by design, is lasse faire! There is no "mandating" ANYTHING! Anybody can hook up to their neighbor, who hooks up to some guy across town, who is hooked up to a couple other folks...
The Internet is DECENTRALIZED and OPEN. The closest it gets to mandating anything is the much-disputed RBLs. I, for example, block all email from most Asian countries - nothing personal, but it sure drops the SPAM load with virtually no complaints. But, I can't mandate what the Chinese or Koreans do with their network - I can only mandate what they do with respect to MY networks.
The Internet is merely a commonly agreed upon set of standards for communications across disparate networks, and it's performing the task of connecting networks the world over with grace and flair.
Don't tell me that just because Windows systems get infected in 12 minutes, that the Internet is broken. Sorry. The Internet is working fantastically. It's Windows that's broken. It's not up to the task of functioning on a globally accessable network.
So far, every significant "problem" I've heard with the Internet hasn't been with the Internet, but with the systems at its fringes. SPAM. zombies. Worms. Viruses. Exploits. All are simply side effects of a "zero friction network" as espoused by the all-knowing Bill Gates in his 90's book, "The Road Ahead", combined with systems not able to cope with the ramifications.
Bill Gates, Larry Ellison, Scott McNealy, Linus Torvalds, and all the others are learning now what that truly means, and over the next decade or so, we'll see major advances in developing the kind of security needed to handle this frictionless network.
In short: the Internet is doing just fine, people! It's the systems hooked up to it that have problems!
Because that wouldn't look suspicious at all if they ever found it.
It's HIS stuff. HIS box. HIS wall. Having computers in the wall is not illegal (not sure, it may be against the building code in some areas, but it'd be a stretch)
What's to be suspicious of? I've considered putting one or two of my main (home-based) systems in an obscure cabinet (that looks like an Air Conditioner) in the cellar instead of out in public view, just to deter theft.
Also, you'd be doing drywall and paint work every time the stupid thing ate a disk.
That'd blow. I'd suggest the obscure cabinet in the cellar, first.
You're forgetting that the licensing is per developer. If it's hard to understand, just imaging not receiving a paycheck for one month. Now go and rethink your post.
That changes almost nothing. Remember the "years" part of my post. It's not atypical for such a programming framework to save much, much more than a month in a 2 year project, and then there's maintenance after the fact.
Sorry. If you think that $6600 is unreasonable, you are lacking in experience.
Depending on the economics of your business, it may be worth the money, but "very affordable" it ain't.
If you think $6600 to allow for the productive development of software on all three major platforms, simultaneously, is EXPENSIVE, you are lacking in experience.
$6600 is a midline wage for a single coder for one month. Any decent sized project goes on for YEARS, and usually involves at least 2-3 coders.
$6600 is a drop in the bucket if it saves even 5% of developer costs over the long haul! A single sale can pay WAY MORE than $6600 when you are talking about custom, vertical apps, and that sale might well be made on the back of "*nix/Mac/Win compatable"...
Cross-Platform is a selling feature again!
Really, it's only the great works of artistry that need to be retained and remained, sustained and maintained. Historically, it's interesting to catalogue art, but politics? The everyday communications that lead up to the horrible decisions that lead our politicians to make the mistake of the daily business? We want records of this?
Absolutely, yes!
History is often taught as "Charlamagne took over Constantinople in the year 12xx" as though military feats really mattered to the average Joe. But, the truth is, America was colonized by people who thought that, however bad it might be in a virgin land, it was BETTER than their lives in Europe.
One of the key failures in public education today is to communicate the understanding that history is comprised mostly of PEOPLE doing ORDINARY things in their time to make life better for themselves and their families. They loved, worked, got bored, and cracked jokes at the expense of their leaders, just like we do today.
History doesn't consist of battles, anymore than history consists of artworks. Capturing more detail in the average, everyday lives of people gives a much better understanding to the cultural norms, and the ideals to which people aspired.
The pyramids of ancient Egypt provide a clear, artistic monument to their culture, yet we have an only modest understanding of their day to day cultures. Similarly, we have Stonehenge as a clear monument to the grooved-ware people of the English isles, but almost NO understanding of who they were and what they felt was important. How much would a true historian give to understand the day-to-day culture of these mysterious "grooved-ware" people of ancient?
Those memos and IMs comprise that understand of people today.
There is no theoretical upper limit on text compression as far as I know
Which is obviously some hot gas coming from your posterior. Otherwise: 1 (the Holy bible, heavily compressed)
The amount of compression possible in a given string of numbers is inversely proportional to the amount of randomness in the input.
IMHO, 9 times out of 10, knowing somebody will get you farther than another bullet point on a resume
Yeah. If you're any good, don't spend time in class, spend time getting to know people! Put in some volunteer time at the local school. Hit the streets - get in touch with businesspeople through your local Chamber of Commerce.
Getting the good stuff, where they like you, appreciate you, and thank you as they hand you your check comes down to who you know.
The good stuff comes over dinner between two executives, or on the golfing green, or in a Saturday afternoon phone call, as in "my tech guy is leaving next month, who do you know?".
If you can be the name that slips those lips, you're in for some good quality work!
When you have a good rapport with somebody with some clout, ask them who they know that might need your services! Be friendly, and offer them a 5% or 10% kickback so that they can feel good about refusing the money. (and will see how important they are to you!)
Most everybody loves to help out, if it costs them nothing.
What what you do is take put your ISP's mail server in your DNS records for SPF, since the ISP's mail server is obviously considered an authoritative host to relay for your domain(s). (tough, huh?)
PS: You might want to avoid casual use of profanity - swear words are "power" words and excessive use reduces their power to create an effect. The end result? They fail to add power to your words, and make you look like low-class scum, or at the very least, just a kid who hasn't figured this out, yet.
I mean, go for it if that's the effect you want to create, otherwise...
