Passwords

Author: Steve Martin

If you are anything like me, you have dozens of different web sites that you are required to log into in order to access information. These may include your e-mail accounts, shopping web sites, banking web sites, credit card web sites, school sites, even blogging requires a password to get in and write new posts. These sites require passwords for good reason. You wouldn’t want someone jumping into your Amazon account and buying lots of stuff on your card would you? Or, think about the headaches of someone getting into your banking account. I know some people personally that have had people get into their ebay account and change pricing on their listed auctions.

You may have noticed my post (two before this one) called “Protected: Highly Confidential (Password Protected Post)“. Well, I guess I have some pretty curious siblings because two of them decided they were going to “hack” into that post (and they were successful). I don’t really care who gets into that post which is why I gave it a VERY simple “password”. But, it brings about the question of how important secure passwords are. Think about the password (s) you use for the various sites you visit. Are they just a single word? Not good as any dictionary tool could crack it. Are any of your passwords just a important date? Not good as anyone that knows you probably knows any important dates in your life or could easily find them out. Does your password contain letters AND numbers? Better. At a minimum, I would suggest using letters and numbers. You may want to throw in some unusual characters like % or & or #. Make your passwords at least 8 characters in length. The idea is to make it VERY difficult for anyone to guess.

So, if you have easy to guess passwords, I would suggest you start changing them to something a bit more difficult to guess…..because my siblings are on the loose and may hack in at any time.

$40 off 1TB Hard Drive

Author: Steve Martin

This is a great deal. I haven’t seen a 1 TB hard drive this cheap ever. So, I thought I would share it with anyone in the market for a bigger hard drive or an extra hard drive. For those that don’t know, 1 TB is 1,000 GB. That equals a lot of room for data. It is a deal from Dell and is $40 off 1TB SATA Barracuda 7200.11 Internal Hard Drive! Coupon Code: 9BPJP5C2PHKMMC. That coupon code is important. Use the link above and add the item to your cart and then apply the coupon code and it will take off the $40. Shipping is very decent too.

This is my list of technologies that you should never use or you will be in for it. The problem with these technologies is that they are too nice to be without once you have tried them. So, you can either take my word for it and stay far away from these technologies or try them and forever be hooked. They are in no particular order.

Cell Phone – I got my first cell phone back in 1998 when Sprint had a promotion for 100 minutes at only $10 per month. What a deal! I was going to finally have a cell phone and it was going to be so cheap. That is until you find out how long 100 minutes really is. You go through 100 minutes in no time at all. Especially because they didn’t offer any evening weekend minutes or Sprint to Sprint minutes. It was 100 minutes total. When I would check my voicemail, it used up minutes too. I was very careful with my minutes at first, and then I just had to have more so I upgrade my plan and am now up to a family plan with 3,000 minutes shared among 6 phones with unlimited evening weekend and Sprint to Sprint. I also have a Sprint datacard for my laptop. So, while Sprint gave me such a great deal up front, they have probably made plenty of money since. Good marketing Sprint. So, be warned, if you get a cell phone, you will not be able to not have a cell phone.

DVR – A DVR (Digital Video Recorder) changes the way you watch TV. The brand of DVR that you probably know the best is Tivo. They revolutionized the concept and made it so simple for anyone to use. Most of the major manufacturers of electronic equipment have some type of DVR available and you almost can’t subscribe to satellite without them throwing in a free DVR. I am stationed in the Microsoft camp for my DVR using a Windows XP Media Center PC. I find that having a computer be the DVR, I can utilize it for so many other things as well. The concept is very simple, a DVR has a schedule of all of the programs available from your TV provider (you tell it which provider you use). You run through the schedule and tell it what to record and whether to record it just that once or to continue to record that same show whenever it airs. Then you forget about it. When you are ready to watch your show, you go into your recorded shows and push play. You can then fast forward, pause, and rewind that show and keep it as long as you have the space on the DVR. DVRs are also great for live TV as you can hit pause whenever you want and take a potty break (something we have to do frequently for our kids or they’ll wait too long and….). Anyway, you get the idea. You can read about our DVR withdrawals when I fried the TV tuner in the computer. We are now back up and running but it was rough to be without the DVR.

Computers/Internet – Yes, there are still people that have not really used a computer. My mother-in-law is one of them. She actually refuses to use one. I think she’s afraid that if she were to learn to use a computer, that her husband would put her to work. She doesn’t understand that if she were to use one, she could do so much more for herself. Computers are about the most useful and time saving devices that exist. If I can ever get my mother-in-law to actually use one, there’s no going back. She does not understand this. I know that once you learn the basics of the computer your life is forever changed and you are able to do so much more than you could without one. The Internet makes a computer about 1,000 times more useful and time saving. There is nothing that even compares with the Internet with the vast amounts of information at your disposal once you get connected. So this one is kind of a two part technology to never use, a computer with the Internet. You can do a lot with a computer but you can do SO much more with a computer connected to the Internet.

GPS – When I would travel to a place that I had never been to before and try to navigate new streets and find desired destinations, I would get nervous, stressed and frustrated. Even when I would map out my itinerary ahead of time, it was difficult to follow the map and try to keep my eyes on the road. Missing turns and going the wrong way was common back then. Now, I have GPS and won’t be able to be without it. It is a stress reliever. When we bought our van, we chose to get the model with GPS built in and let me tell you, it is so nice to have. I use it more than I ever need to. I turn it on first thing when I get in the van even if I know where I’m going. There’s something about seeing that little red arrow tracking my every movement that gives me comfort. Even if I have no idea where I am, it does. It can find restaurants and stores and gas stations for me. It calculates the best route to any destination I can throw at it. If I miss a turn, it re-calculates the new best route from my new “missed turn” position. Recently Sprint upgraded the firmware on my cell phone and now I get GPS directions on it too. Since I always have my phone with me, I always have GPS. I love it. Travelling will never be the same once you have experienced a GPS unit. One of the best things about it is that once you have purchased the actual GPS unit, it is completely free to use.

Texting – For the longest time, I didn’t see the big deal of texting. I thought it was stupid. I already had several e-mail accounts, what did I need texting for? I touted it as a fad of the younger generation that I must have just barely missed. Well, we just upgraded our Sprint family plan and we now have unlimited texting on all the phones in the plan. I still don’t send a lot of texts but I must admit that there are times when sending a text is the perfect thing. Sometimes you don’t have time or you just don’t want to have a big conversation with someone just to get a tidbit of info from them. A text allows you to get the info you need quickly and unobtrusively. Most people carry their cell phone with them everywhere (except my wife, it drives me crazy). So, when you send someone a text, chances are they will read it very shortly after you sent it. So, you can ask a quick question, make a quick comment or even update your facebook status via a simple text. I do feel there are times when it is NOT appropriate to text in place of an actual phone call. The current high school and college students might not agree but I don’t feel that it is appropriate to send a text message to ask someone out on a date. In fact, this is a technology that should not be abused by replacing real conversations. Many of the young people of today talk more via texting than they do with their mouths. But, it can be fun to be with a group of people and be able to say something to a person there without anyone else knowing what you said. Whispers can be overheard and everyone knows you said something secretive, but if you send a person in the room a text, nobody will necessarily know it was from you, it could have been from anyone anywhere. So, if you do get into texting, text responsibly.

And there you have it. My top 5 technologies that you should never use or you’ll not be able to stop using them. I look forward to future technological developments that we should not take part in so that I can be hooked even more. If you haven’t tried some of the above techologies, think twice before you check them out because once you do, you can’t go back.

Returning the Cell Ranger

Author: Steve Martin

I recently used the Cell Ranger on our first vacation in about 5 years. We went to Disneyland and had such a fun time. We might have to make this vacation thing a regular event. I am still not sure what to think of the Cell Ranger. That is why I am returning it. If it did anything to improve my cellular reception, it wasn’t really enough to notice much of a difference. If I am going to use and promote a product, it has to be a great product. Mediocre products do not receive my endorsement.

So, I have contacted the manufacturer and requested a refund. It’s too bad because I would have loved to have endorsed the product and sold a ton of them. Oh well. Hopefully something even better will come along. If it does, I’ll test that out too and let you know how it goes.

I am currently in our mini van on the way to California from Utah. I was excited to test out the Cell Ranger on this trip and see if it improved my cellular and data card reception. I have the antenna magnetized to the roof. Now it is a little difficult to say if it is the Cell Ranger or just an improved Sprint network but the connectivity has been great. Right after St. George is a big canyon that always had horrible reception in the past. It has been about a year since I have been through it. This time the data signal from the data card only dropped once. I was amazed. But again, I don’t know if Sprint just improved their coverage through there or if the Cell Ranger is actually doing what it claims it can do. For now I am going to believe it was the Cell Ranger. Maybe on the drive back I’ll turn off the Cell Ranger and see how long I stay connected.

Cell Ranger

Author: Steve Martin

This is a product I have recently stumbled across. It is a cellular signal enhancer for those of us that suffer from cellular signal dysfunction. No, it isn’t blue. It is a very simple device and comes in two version for power purposes. One is the USB version and can plug into any USB port to receive it’s power (pictured). The other uses a standard 12V cigarette plug for power.

I would recommend the USB version because you have a lot more flexibility in where you can use it. They make cheap little 12V and regular power adapters that have a USB plug on them to power up any USB device without needing to use the ones in a computer. You could is one of these adapters to power up the Cell Ranger as well as any other USB powered devices you may use.

Anyway, you simply plug this little device into a USB port and it starts boosting the cellular signal around it for about 6 feet. It claims it will boost the signal by about 2-3 bars, thus improving clarity and preventing dropped calls. It actually has a microprocessor in it that takes the cellular signal and repeats it at a low level right around the antenna. It works for both cell phones and data cards on any network (except for some Legacy iDEN Nextel signals also used by some Canadian cellular providers). 

The unit costs $150 plus shipping. It can be used anywhere to give your cellular signal a little boost. Currently, I have never actually used a Cell Ranger but I intend to change that. I have one ordered and plan to test it out on an upcoming trip to Disneyland. I figure that it might be useful in the car on the way down and back up and will hopefully improve the signal I get from my hotel room. You have to think about your ability to connect and work while on vacation when your company consists of you and only you. When I have some more experience with the Cell Ranger I will give an update on its claims. If I like it, I will become a reseller and be able to sell the device at a discount. For now, you can get more info by visiting their website directly at www.getcellranger.com.

Hard Drive Crash? Try Drobo.

Author: Steve Martin

I believe that it is a fact that all hard drives will eventually crash. This is why I make sure that I setup some kind of a backup for my clients. It is extremely important to have some kind of a regular backup in place. If you are manually backing up your data, make sure you do it regularly. DON’T FORGET! It would be best to setup your backup to automatically happen on a regular schedule. This will save you all kinds of pain, frustration, time, financial loss, blood, sweat, and tears. As soon as you start using a computer, start backing up your data. I have seen the hard drives of some clients last years and years. But, The hard drives in two different servers lost a RAID 5 hard drive (this means that no data was lost as we just needed to replace the missing drive in the array) after about 2 years. another client’s hard drive lasted about 4 years (not in a RAID 5 array) before it died. He luckily had most of a backup and lost very little data. I have also had a couple of workstations lose a hard drive after only a couple of months. In the workplace users will typically save their data to the server which is backed up and therefore we don’t backup the individual workstations. So, while these two workstations didn’t really lose much data, it could have been much worse.

I recently had one of my movie storage hard drives fail. It was a 500 GB external hard drive and it was pretty much FULL of movies. Did I have this hard drive backed up? Nope. In this particular case, the data was not all that valuable as I can easily redo the movies since I still have all the original DVDs. But, it will cost me a lot of time to redo all of them. It is a very good time to reflect on my backup practices though.

A while back, I ran across a very unique product targeting backup, although it may be reliable enough to use for everyday file usage and storage. It is called drobo and is short for “Data Robot”. It is basically an intelligent external hard drive.

It is a small box that can hold 4 Sata hard drives of any capacity. It has a unique new proprietary kind of RAID protection built in. It makes sure that if one of the hard drives inside it fails, your data stays completely in tact. And, not only that, but it lets you continue to work as if nothing happened. It alerts you by the lights on the front that something is wrong. You would then simply replace the failed hard drive with a new Sata drive of any capacity and it re-adjusts to provide you the additional space of the newly inserted drive.

I have known about the drobo since the first version and held off buying one for a few reasons:

  • First, price. This little baby costs $500 without any hard drives in it. While that isn’t a ton of money for this kind of protection (it’s actually kind of cheap when you look at the inferior competitors) it is enough to make you think twice about whether or not you really need this device instead of a couple of standard (stupid) external hard drives.
  • Second, version one was a bit slow in reading and writing to the device. If I am going to use this for daily use of files, I need it to be decently fast. They fixed this in version two. Reading and writing are now approximately twice as fast as version one. (If you just want to use the drobo as a backup device, you can still pick up version one for around $350 while they close them out.)
  • Third, I wanted a network attached storage device so that I didn’t have to leave a computer on in order to access the files. I could simply attach it to the network via a network cable and my files would be available to any of the devices on my network. Droboshare took care of this. Droboshare is a small attachment with an Ethernet port that connects to the drobo via a USB cable. It then makes all of the files on the drobo available to the other network devices. This also means a bit more expense though.

 

So, because of my crashed drive, I am going to purchase a drobo to test it out. I may start with just the drobo and add the droboshare later. I will start out with my existing hard drives and add more as my capacity needs grow. The second generation drobo can handle as much as 16 TB of data (first generation could handle up to 4 TB) so, it may be a while before I reach those kinds of capacities. If I fill all of the drive bays with drives and find that I need more capacity, I simply remove the smallest drive and replace it with a larger capacity drive. Drobo works in the background to re-configure everything so that my data is safe and I can begin using the extra capacity. This is not possible with standard RAID 5 configurations on other devices as the replacement drive must be the same size as the lost drive or the RAID array will not recognize the new drive.

I will let you know whether I like the drobo or not once I have one in my hot little hands to test. I plan on putting it through it’s paces to make sure it is a valuable investment. I may become a reseller of theirs if I am pleased with the results. Either way, backing up your data is crucial. If you haven’t thought about backing up your data, why don’t you go get started right now. You never know when your hard drive will crash.

Post Control in WordPress

Author: Steve Martin

I have setup a bunch of WordPress blogs for family and friends and have actually had several people abandon these blogs because they could not control who sees them. Some might be a little paranoid but still. They would like to be able to control who can see which posts. I know it is possible to make a blog private by requiring a user account and make it all or nothing but I would like to see more control than that.

When you write a post, on the right you have a checkbox to make the post private. That is great but I think we should add several more checkboxes such as Everyone (anyone visiting can see that post without having to log in), Family (Only logged in users that have been marked as family can read these posts), Friends (Only logged in users that have been marked as friends can read these posts), Co-Workers (Only logged in users that have been marked as Co-Workes can read these posts), etc. The group names could be customizable but you get the point. You should be able to mark a post for multiple groups unless one of those groups is Everyone or Private. These two would trump anything else. Private posts would remain visible to the author of that post and admins only.

These groups are completely different than the user rights currently in WordPress as these would only control who could READ individual posts. The ones currently in Wordress control user rights and what they can DO in Worpress.

For me, I don’t care who reads what, but I have been asked about setting something like this up for several users and have not found any plugin that can do this. It seems very simple but I am no code guy and I actually do not think this should be a plugin but actually part of the WordPress core. Although I personally wouldn’t really have a need for it. I can definitely see the benefits of such abilities and can see how some of my clients and family and friends could utilize it.

For example, if you have a WordPress blog setup in a business environment, you could allow only certain departments to read certain posts. You may want to setup your groups as Accounting, HR, PR, Manufacturing, Sales, etc. That way, each department head can write things specific to their department and only their department would be able to read it when they were logged in (saves other departments having to wade through a bunch of irrelevant info to find info pertaining to them too). Any post aimed at everyone in the company would be marked with all the departments checked. They could mark anything they want the general public to be able to see as Everyone. So, it could be used for both internal and external visibility.

I guess this is more of a post control wish than user control. Each user in WordPress would then have to be put into one or more post category group. Users could be in more than one post category group but typically they would probably be in just one. A CEO would probably be in every post category group.

Anyway, that is my BIG feature request for the WordPress developers. If you like my idea, vote for it here.
