Diary of a Network Geek

No, seriously!

Okay, so as we approach Christmas, I tend to think of gifts for people and I’ll no doubt post about them.  Okay, so, mostly, these are things I wouldn’t mind getting, but, still, I have good taste, so you’ll enjoy them, too.
So, clearly, you can tell that I’m no web designer from the way this site looks, right?  Well, believe it or not, I used to code all the pages for this site in HTML, by hand, using nothing more than a text editor!  Okay, all you design people can stop laughing at me now, thanks.
Anyway, when I saw this book, HTML for Babies, I was delighted!  Finally, I can start training my two-year-old godson to code compliant HTML so that he’s ready to take over managing my websites by the time he’s in Middle School!  You think I’m kidding?  Then hit the link and you’ll see that, no, I’m serious.  This is a book filled with properly coded HTML and simple, positive messages perfect for any toddler learning to read.  It really is baby’s first HTML training manual!

So, go ahead and start your geek young!  The perfect stocking stuffer for your budding web developer!

There are a lot of Linux distributions.

No, really, I mean there are literally hundreds, if not thousands, of Linux distributions out there.
Frankly, it can get a little overwhelming sometimes.  But, I think about them and what they all are and what they do.  I think about them because it’s my job, and because I’m always thinking about what’s coming next in the IT industry.  So, what Linux installs do I think about?  Funny you should ask….
I think about Android.  Yeah, that’s right, the operating system that runs those Droid phones is a kind of Linux.  That’s kind of amazing to me, really, but there it is.  And, I think about it because Android seems to be on more and more devices these days.  Everything from phones to tablets to who knows what next in the consumer market.  But, I try to pay attention to Android because so many people at my office have Android based phones and they all expect me to help them figure their phones out.
I think about Fedora, which is the open source version of Red Hat, which enjoyed pretty good market penetration when they first got going.  They’ve got a lot more competition today, but, still it’s in an IT professional’s best interests to be at least familiar with Fedora.
That goes for openSUSE, too.  openSUSE was bought out by Novell some time ago, so there’s no telling where it’s going to end up with all the buying and selling around Novell’s bits and pieces these days, but it’s still a pretty heavily installed Linux distribution.  My brief experience with it was good, though, I have to admit, that was on older hardware for a personal project, not a corporate gig.
If you’re an Oracle shop, you’ll probably know about Oracle Linux, which is basically Red Hat Linux after Oracle has made modifications to it.  Oh, and jacked the price up.  Still, if you work with Oracle a lot, it’s probably worth looking into.
Eweek recently ran a slidwshow about these, and several other, versions of Linux under the title 10 Linux Distros Every IT Manager Should Know.  Obviously, I agree with some of their listing, but clearly not all.  And, I think they left some off.

For instance, what about the live CD editions?
Two I think anyone in IT should know are Ubuntu and Knoppix.  Knoppix has been around a longer, but Ubuntu has a slicker interface and, I think, is a little better at detecting hardware than Knoppix.  Also, you can install Ubuntu from the live CD media, if you would like, and plenty of people do run it as a desktop.  The real plus is that there’s a pretty healthy community around these two installations, especially Ubuntu.  So, if you need help with either one, there are a lot of resources on the internet to answer your questions.
I use these two all the time to recover data of damaged installs of Windows.  I even used one to build a PC imaging system before I started using Clonezilla, which is also, incidentally, based on Linux.

If you’re worried about security, Linux can help with that, too.
For quite some time, the National Security Agency has sponsored SELinux, which is a pretty secure, hardened version of Linux.  They designed it to be reasonably secure right as a default, since an insecure default install is usually where security problems start.  Of course, you may not trust the NSA.  And, while this is “sponsored” by them, it’s not actually an official US Government Linux install.
For that, you have to go to the US Airforce.  Their Lightweight Portable Security distro is the first official US Linux distribution.  I haven’t actually tried it myself, but ZDNet has a pretty good review of it.

So, as you can see, if you haven’t looked into Linux much before, there are a lot of things to investigate.  And, as a computer professional, I DO recommend that you check out at least some flavor of Linux.  It’s so prevalent and so flexible and handy to have that if you haven’t bumped into it yet, you will.  So before you need to know it, investigate it some on your own.  You’ll be glad you did.
(And, I’m sure every seasoned IT pro has their favorite distro, like Debian, but there are too many to list them all.  If you have opinions about any, please, leave comments!)

Looks like they’re about to go up.

And, if what I’m reading in the media is any indication, by quite a lot.
I know I mentioned this a couple weeks ago, but the tech media seems to just be really catching on to this.  The folks over at ExtremeTech, who are really into their hardware, have a great article about what’s going on with drive prices.  And, perhaps more importantly, what they think is going to happen to drive prices.  In short, it’s not good.
Seagate is expecting shortages in their supply chain for “several quarters”, and that, of course, translates to a higher demand.  And, for all of  you who slept through your basic Economics course in school, higher demand on a limited supply results in higher prices.

Of course, this is all due to the terrible flooding in Thailand, where key components are made for a number of electronic systems.  I’d expect that shortly after Christmas, a number of things will go up in price.  Anything that relies on a drive for a key component, like PCs or laptops or network attached storage, will clearly cost more.  But, I expect a lot of different cameras and similar electronics to go up in price, too.
This is the downside of a global economy.  And, it’s also why we should be concerned with the welfare of our fellow humans on the far side of the globe.  We’re all interconnected, now more than ever.  I hate to equate such an enormous disaster with our creature comforts and the price of consumer goods, but, well, it’s the only way some people can get their mind around how important it all is.
The world is so interconnected now, what happens in any one country, no matter how small, has far reaching effects on the entire world.

There is one, apparently.

So, it seems someone has figured out the answer to an old question which has often plagued IT professionals: How long are your skills good?  According to Eric Bloom, over at IT World, longer than you think.  He claims that the tech skills you have now will be half as marketable in two years.  If you read Slashdot, you’ve seen this article and the comments that followed.  Here are my thoughts, though.

First, I think it depends on the skills involved.
For example, if you’re working on Windows Server, your skills will probably translate fairly well and that two-year half-life is about right.  For Unix, maybe a bit longer than that.  For Novell, well, sadly, I’m not sure who actually uses that old warhorse any more, as much as it makes me sad to write it.  For other, less vendor oriented skills, I think two-years may be a bit short-sighted.  Take routers, for instance.  Now basic routing hasn’t really changed in quite a long time.  Even Cisco routers, the creme-de-la-creme of enterprise routers, haven’t really changed that much on the inside in the last 15 years.  I was in one the other day and I have to admit I was shocked at how quickly the skills came back to me after quite literally years of disuse.  Far more than two years, I might add.
Also, skills that are a little harder to quantify certainly stay “fresh” longer than those hypothetical two years.  Things like troubleshooting and the so-called soft skills involved with user support are something that I think are deeply engrained in someone.  They’re part of a work ethic.  So the customer service skills I learned more than 20 years ago when I worked for Hyatt Hotels are certainly still more than “good”.

Secondly, Mr. Bloom is talking about marketability, not actual utility.
So, the fact that, for instance, I don’t have a Cisco certification, even though I’m clearly capable of configuring a Cisco router, means that quite probably was never what he would have considered a “marketable skill”.  In fact, based on what many recruiters may have felt about the marketability of my skills, I should be farming beets right now, not working as the Lead Tech/IT Manager of a fairly prosperous design and manufacturing company.  Instead, of course, all through my career, I’ve managed to talk my way through the door and then show the people in charge that versatility and adaptability, not to mention mad Google-query-crafting skills, are far more important than any specific past experience or certification.

So, what about you, gentle readers?  What do you think?  How long are tech skills “good”?  And does working on legacy systems harm your future employability?

Getting ready for a job interview?  Be prepared!

I’m an old Boy Scout, an Eagle Scout, in fact, so I’m always thinking about “being prepared”, whether it’s a trip to the zoo for photography or a job interview.  Scouts taught me, among other things, to think about situations long in advance of being in them, so I can prepare for what I might need and what I might need to do if things go wrong.  There are thousands of ways this applies to being a professional geek, but, today, I’m going to focus on one way in particular: job interviews.

DICE ran an article back in November of last titled Interview Questions for Network Managers.  It’s good.  If you either are a Network Manager of some kind or plan to interview one, go read that article.  Seriously.  Of course, when I’ve been the interviewer in these situations, how the candidate got to the answer mattered to me as much as the answer itself.  The point of questions like these, for interviewer and candidate, is to display how the potential network manager thinks.  How we think about our networks and solve problems on them matter a whole lot.  I remember working with one guy who, basically, tried things randomly over and over until something worked or he broke it completely.  He never did understand the concept of changing one thing at a time to find out what was wrong so we could stop it from happening again.

In any case, I know a lot of my IT comrades are out of work out there and interviewing, so I thought I’d remind them of this resource to help prepare for future job interviews.
Good luck out there!

Okay, a bit more than a word…

“Content is king”, they used to say. The idea was if you wrote enough compelling material for your blog or website, then the readers, and search engines, couldn’t help but find you and rank you well. Sounds like a great idea, right? Then why do so many people write such bad content?

I don’t know either.
What I do know is that everyone and their brother have an idea about how to write good, compelling content for your blog or website. Take SEO Book, for instance, who ran a post about writing better blog posts back in December of 2008. They, in turn, referenced Seth Godin and a book titled [amazon_link id=”0060891548″ target=”_blank” ]On Writing Well[/amazon_link].
Now, I’ll grant you, I tend to share links to other resources, offering an opinion about them usually, but not as much original content as I’d like.  But, still, I think that even those posts are written reasonably well.  And, I think it’s worth taking the time, even on a blog, to write well.  Not to improve my rankings in search engines, but because writing well, communicating clearly, is a worthy pursuit.  It may not always be obvious here, but I actually worked quite hard to become a competent writer well beyond things like English class in high school.  One way or another, I’ve written for years and take pride in my ability to write clearly, concisely and in an entertaining manner.

You see, the thing is, as much as we love video and photos and graphics and the like, in the end, we use words to actually communicate.
The next time you’re driving down the street in whatever town you live, notice how many signs have writing on them.  Or, better yet, notice how many signs are, in fact, themselves, writing.  Words, and writing, is still the medium we use to express ourselves, even on the web.  How we write is an expression of how we think.  Writing well is an essential skill that displays our intelligence and our education.  Writing poorly, with sloppy grammar and with “text message” abbreviations, subtly tells people that we are not as smart as we claim to be, and not to be trusted or believed.  Writing well, on the other hand, assures our reader that we are smart, trustworthy and competent enough to be relied upon.  Our writing, especially on the internet, can be, as they say at Google and Wikipedia, considered “authoritative”.
I have argued with people via e-mail and comments who, when they found themselves in metaphorical quicksand, insisted that they would argue circles around me in person.  I questioned how that would be possible if they couldn’t write sufficiently to defend their position when they had all the time they needed to consider the argument at hand and edit their work before replying.

Which brings me to the real point of this little screed; editing and revision.
I know the web is a fast and furious place and that fresh content is the most important thing, but, I do think we have the time to edit and revise articles, even short ones, before making them public.  And, we can all use spellcheck now.  In fact, the version of WordPress that I’m currently running has spellcheck and grammar check built into it.  I would think more people would take advantage of this feature, as well as the ability to save posts in a draft format for later review before posting.
Granted, not every post is going to garner that sort of care and attention, but shouldn’t more of them get it rather than less?  If we are our words on the internet, shouldn’t we care more how we sound and what we say?  I think so.

I think it’s worth writing fewer words, or even writing fewer entire posts, so that a certain minimal attention may be paid to the content and style.
In short, I think if it’s worth saying, then it’s worth saying well.

No, seriously, it is.

If it makes you feel any better, most people’s passwords are too weak.
I suppose you think it doesn’t matter how “strong” your Gmail (or Hotmail or whatever free email you use) password is, right?  Well, you’d be wrong.  I recently read an account about how one person’s Gmail account was hacked and used to spam and try to get her friends to send the hacker money, all posed as her.  Of course, that was after deleting more than 4 Gigabytes of stored messages and photos.  You can read that account, as told by her husband, over at the Atlantic, in an article titled “Hacked!”  It’s worth reading, especially if you’re not in the IT business.  And, frankly, even for a fellow professional computer geek, it might be eye-opening to see how hacked email accounts are being used these days.  I have to admit, I was a little surprised that the attacker in question actually used the account personally to try and con money out of the victim’s friends and family.

I was not, however, all that shocked to see how many accounts are compromised on a regular basis.  Think the thousands.  Daily.
Right, so thousands of email accounts on which people depend are hijacked, used and abused on a daily basis.  If it hasn’t happened to you, it’s probably only a matter of time.  So, how do they do it?  Shared, easily guessable passwords.
Yes, it’s that easy.
Stop for a minute and think about how many passwords you use on a regular basis.  How many are the same?  How many accounts do you have for things like bank accounts and credit cards and medical records that use the same password as your email?  And how many of those accounts use that same email address as the username?
Getting the picture?

So, what do you do?
First, stop reusing passwords.
Second, make more secure passwords.  And, don’t think that the old way of replacing “L” with the numeral one or the letter “O” with the numeral zero and that kind of thing will work, either.  The hackers are on to that.  It’s better to use words that are not in the dictionary.  So, yes, made up words.  Or, even better, phrases, which is what I’ve recommended for some time.  Having a hard time coming up with one?  Try using one generated randomly for you at passphra.se, a random passphrase generator which was inspired by an XKCD comic.  The comic explains the reasoning behind the passphrase idea and the generator.  Also, XKCD is pretty funny and if you’re geeky like me at all, it’s well worth checking out.

In today’s world, we’re way too interconnected and digital and reliant on those systems to have relaxed security.  It doesn’t matter if you’re a geek or not.  Please, think about your passwords and how easily they might be compromised.  Then think about what that might mean to your life, digital and otherwise.
Now, if you’ll excuse me, I have to go change some passwords…

Dearest Search Engine Optimization Experts:

Please stop e-mailing me unsolicited requests to “help” me with my search engine placement.  You found me via a search engine, because I’m damn good at SEO, so I don’t really need your help.  Nor do I want your “help” cluttering up my blog with scripted, canned, generic posts written, no doubt, by starving college students and/or starving IT workers displaced by the economy.  Nothing against them, or your services, I’m sure both are brilliant, but this is kind of what I do.  Also?  It’s kind of how you found me in the first place.  So, you know, logic dictates that if you could find me to fill my inbox with unsolicited advertising, then people who actually matter to me can find me, too.

I understand that I’m not really your regular market, so maybe you were trying something new with me.  Well, please, stop.  It’s not working.  I don’t want to hear from you or know about you or have to delete your pitch for whatever internet snake oil you’re selling today.  Really.  I don’t need it and I’m not buying.

So, really, thanks for thinking of me, but, please, go away.
I don’t need advice about adding keywords to my titles or headers or what metatags I should include in my code.  I don’t really need someone to write articles designed to pump up my Google juice.  I can do that myself.  All of that.  (Also?  Metatags haven’t mattered for years now.  Honest.)
Anyway, your offer was very nice, and what little bit I read seemed well written enough, but, honestly, no thanks.  I’ll just stick to what works, what helped you and your snake-oil-selling brethren to find me in the first place: I’ll just write relevant articles and continue to produce the personalized content that only I can produce.

Thanks!

(P.S.  Also?  No, I don’t want to make extra money writing for you and your internet snake oil business!  Now, stop sending me the damn email!)

No, that’s not candy.

Though, I have to admit, sometimes the industry treats them like candy!
No, I’m talking about technical certifications, which are, I think, the bane of the IT industry now.  Folks over at TechRepublic are talking about tech certs and their relative value.  Personally, I don’t think they are that valuable any more.  Oh, back in the day, I think they were and, to a degree, they solve certain problems for hiring managers, but, I don’t think they matter as much any more.  Of course, maybe that has something to do with where I am in the industry and job market, too.  I am, frighteningly enough, a seasoned professional.  So, my work history and experience count for a lot more than the handful of certifications I have.  (For the record, I’ve been Novell certified since 1994 and Linux certified since 2003.)
As far as I’m concerned, the only thing my certs are good for any more are getting past a Human Resources person acting as a firewall to the hiring manager.  Usually, if I’ve done all my homework like I should before even applying for a job, once I get to the hiring manager, I’m pretty much in.  And, honestly, they don’t normally care about my certs.  They care about my ability to execute.

So, what do you think?  Are professional certifications like this worth the paper they’re printed on any more?

I recently finished reading [amazon_link id=”0307465357″ target=”_blank” ]4-Hour Work Week[/amazon_link] by Tim Ferriss.

I have to admit, I like the idea of working four hours a week and then pursuing my own interests the rest of the time.  You may not know it from how little I’ve posted here lately, but I do have interests beyond working a lot and high-tech geekery.  Realistically, because of how I do what I do, an actual four hour work week would be pretty difficult.  Of course, the book advocates doing something all-together different than a “regular” job.  Naturally, one of my major concerns as a cancer survivor is health insurance.  The book doesn’t talk too much about dealing with the health insurance issue.  However, it does talk about alternative revenue streams and different ways of generating income.  At least, generating income enough to live in an entirely different way than most of us “9-to-5-ers” do currently.  Or, for people, like me, unwilling to give up their “regular” job and the security it represents, Tim talks about working remotely and having flexible office hours and availability.
Personally, I’d be thrilled with getting out of debt and have some more flexible hours.

In fact, in my industry, things like remote work or flextime are quite the buzzword lately.
Now, keep in mind I mean “data technology and networking” as my industry, not the company I currently work for, who builds cranes.  In the networking world, we’re often asked to provide solutions of varying scales to let people work remotely, whether from home or elsewhere in the world.  For example, even though we’re a “little” company that makes great, big cranes, we still have people in multiple permanent locations on two continents.  Well, at least, several locations here in the States and one in the U.K.  But, I have service people who might be literally anywhere in the world.  Our cranes are pretty much in every off-shore oil-field now, so I may have people who’d like to get to a central server from almost anywhere.
And, besides the people who travel for work, I know that there are certain circumstances where people would like to work from home.  For instance, our Sales department is pretty tiny, so they’re always working.  And, if they have a big project, their day could easily stretch into more than ten hours or bleed over into the weekend.  I’m sure they’d love to be able to work from home sometimes.  Not to mention the engineers or draftsmen who might have a family emergency.
Or, even me, on occasion.  A lot of what I do I could probably do remotely or over the phone.

But, here’s the thing; not everyone feels that way.
I know from at least the anecdotal evidence in Tim’s book that people can be more efficient and productive working away from an office.  Certainly, with fewer distractions, I seem to be able to accomplish more.  And, when I get more done, I’m happier!  But, according to Baseline Magazine on-line, there are “risks” involved in flextime.  Frankly, I question their methodology for data collection.  For instance, they list several of the negative consequences of flextime, and by extension remote working, as “negative comments from supervisors”, “unfavorable job assignments” and “denial of promotions”.  But, those are pretty damn subjective and rely on opinions of workers who are using flextime, not actual facts.  Another “criticism” of flextime is that managers think that the best employees should be available 24/7 to handle whatever comes up and that the fewer personal commitments an employee has the more productive they are!  Well, of course!  The ideal employee is a robot who exists to work without ever taking a break!
Frankly, this sounds like someone pumping up junk research to make an article out of it.

Most people I’ve known who work from home actually put in more hours than they would at the office.  And, clearly, a lazy employee who needs structure to perform well is not going to produce when working remotely without someone to micromanage them.  Clearly, this won’t work for everyone, since lazy people will be just as lazy at home as anywhere else, but I don’t think that’s a valid criticism of the entire concept!

Well, in any case, I know that I’ll be looking into ways for people to work remotely that are low-cost or free.  If anyone knows of a free open source equivalent to Citrix, please, let me know!  I may start to look at the free OpenVPN as a possibility, too.  If anyone has any experience with that, I’d love to hear it!
