set default DISK$DATA:[OS.EOL]

Seeing the news the other day of HP is discontinuing OpenVMS brought back some memories. Mostly of all the different operating system’s I have used that are no longer around or have changed a lot. Back in my undergrad days, one of the first OS’ we used to program on was OpenVMS on a VAX. It was for an engineering class and we had to use Fortran 77. I remember our quota’s used to be about 5MB in size, which at the time was “huge”.

So to list some of the other OS’ I have seen gone by the way side (and other computer related items that had a huge effect on where I am at today.)

1. OpenVMS (used it between 1994 and 1999)

2. VM/ESA (not really gone, now called zOS, but haven’t touched it since about 2001)

3. Gopher (this is the “original” web…)

4. IRIX (SGI’s UNIX platform. I still have 2 SGI Indy’s and a copy of 5.3 and I believe 6.5, but haven’t had them on in years, maybe a vacation project some time.)

5. SunOS (not Solaris, but the old BSD based SunOS 4.x) my things have changed in the 19 years that I have been doing Solaris work

6. mSQL (mini sql). Not really gone, but surpassed by other’s (mysql, mariadb, etc). I used msql as my first PHP/FI + DB + Apache installation on a Solaris 2.6 box. I wrote a network management application that controlled DNS, DHCP, etc for university dorm connection management.

7. Trumpet Winsock, for the good old Windows 3.1 days when you needed a way to do TCP/IP over modem or ethernet.

8. NCSA Mosaic, the web browser that is credited with popularizing the WWW. Used to use this on some old SGI and DEC machines.

9. ULTRIX, DEC’s version of UNIX. It was on a lot of DECstations in the Engineering department and one computer in the CS department. Used to have a teacher that made us make sure everything compiled on it vs the Solaris or Linux hosts.

10. AltaVista, Search engine to use before Google came around. Now it is just a “front end” to Yahoo search 🙁

11. Atari 400, used to have one of these at the grandparents house to tinker on.

12. Commodore 64, used to have a couple of these when I lived at home. We I learned some BASIC programming. (Later went on to try Visual Basic programming on Windows 3.11 on a 80486 DX4-100 AMD PC.)

13. BeOS, was a really neat idea, excellent media support, unfortunately it was around the time of the PC vs Mac battle so getting buy in was hard.

 

This all also brings back memories how of rudimentary computers were back then and the lack of security. There was no SSH, everything on the VM, OpenVMS and UNIX machines was done through telnet. There was no SSL, and people didn’t think twice about typing in a credit card number on a web site.

I also remember doing web surfing with Lynx on various UNIX systems. And what goes along with Web browsing then email, the first GUI email client I remember using was Pegasus Mail on a Novell Netware based mail system. Once people started doing POP3 mail, people switched over to Eudora Mail. Which I used for a while, but not a lot. I for some reason stuck with Pine a text based mail reader, mostly because I used it on the server that received all the mail.  (And to totally geek out, there were times were I would telnet in to the POP3 port on the mainframe and read my mail by issuing the pop commands by hand.)

As for personal computers, I have had quite a few since my first one. My first computer only had a 40MB hard drive in it. It was a KLH brand 80386 SX 16 that I bought from Phar-Mor. I think I had it maxed out a 4MB of Ram which at the time was huge. I remember trying to play some game on it (I keep thinking it was SimCity, but may be wrong) and it needed more Video RAM cause it only came with 128K of video ram. So I had to buy more to up it to like I think 384K.

As a list of what I have had or still have, here goes:

  1. KLH 80386SX 16MHz – First, no longer have it, came with a 40MB hd, and a EGA 15inch monitor.
  2. AMD 80486DX4 100MHz – Used this to run Windows 3.11, Linux and later Solaris 2.6. It came with a 320MB hard drive. I later paid close to $300 for a 1.6GB hard drive for it. It had a VESA Local Bus video card and a Sound Blaster 16 sound card. No longer have this computer.
  3. Intel Pentium II 266MHz – Bought this in 1997 from a company called Vektron (who later went out of business, like all fly by night computer places back in the early days). It had 32MB of ram and a 500MB hard drive. It ran Windows 95, Windows NT, BeOS, Solaris and Linux. (I had bought bigger and more hard drives later, just can’t remember what all was in it.) I actually still have this machine, it’s most recent use was as a router for my home network running Solaris 10 with 3 NIC’s (one on Comcast, one on Verizon and one on my home network). The hard drive died in it a couple of years ago, so I turned it off, it is still sitting in a rack thought.
  4. Sun SPARCstation 2 – This was my first “workstation”. I got it second hand from a friend’s company. It was where I cut my teeth on Solaris. It ran Solaris 2.5 when I got it, and over the years I upgraded it to Solaris 7. Ironically it only had a 40MHz processor and 64 MB of ram. It had 2 huge external 800MB disk packs and a freakishly heavy 17 inch Sony monitor that used 13W3 connector with BNC ends. I still have this one, but the disk packs both died, so it hasn’t been on in years.
  5. Sun Ultra5 – 360MHz, 128MB of ram. One of the first “IDE” based lower end workstations from Sun. I still have this, but I think the power supply is bad, as I can’t get it to turn on :(. When it ran, I had Solaris 9 on it.
  6. SGI Indy – 2 of these 133MHz with 96MB of ram. One of the coolest “workstations” I ever owned. I believe they both still run, but haven’t been on in years. One ran IRIX 5.3 and the other ran IRIX 6.5
  7. Dual Intel Pentium III 933MHz – Bought this in probably 2001 I think. It is huge, it was a full tower with onboard IDE raid (which only works with Windows because of driver issues.). Right now it has 1.5GB of ram in it, ~2TB of disk and runs Solaris 10 with 7 zones running on it.
  8. IBM Thinkpad i1100, Celeron 500MHz. This one was given to me as a result of work being done for a company. It was my first laptop, and I still have it today. However it’s stats are very underwhelming by today’s point of view. The monitor is an LCD one, but not TFT, so that means there are all kinds of shadows and the picture isn’t crisp. It also only had a 5GB hard drive in it. Which means after installing Windows 2000 on it, there was only maybe a gig free. It also had no floppy drive, and no network ports. So I bought a Linksys WAP11 back in the day (probably in 2002 when I got this) for upwards of $300 so I could have wireless internet on it.
  9. ThinkPad A22p – 900MHz Pentium III. I bought this one as a replacement of the first. Side by side this one is HUGE, as it has a 15 inch display that runs at 1600×1200. It also had a 30GB hard drive (which was split in to 3 10GB chunks, one for Windows XP NTFS, One for Solaris 10 and one for FAT 32 to share files between the two OS’).
  10. AMD 3600+ – Got this one in 2005. It currently runs a combination of Windows XP and Windows 7. Has about 2.5 TB of disk on it.
  11. Sun X2100 – This server. Currently running Solaris 10, with a surprisingly small 160GB of disk with 4 zones on it.
  12. Apple MacBook Pro 2.0GHZ – This was one of the first Intel based Mac’s that was released in 2006. It had a Dual Core 2.0 GHz processor, 2GB of ram an a 100GB hard drive. It did have it’s issues (mostly battery and power adapter ones), but it ran solid for about 5 years. In the fall of 2011 the logic board “died” and it will no longer run in full “user” mode. (I think it is the graphics part of the board.) Still have it hoping for a price drop of replacement boards some day.
  13. Apple Mac Pro – Dual Quad Xeon 2.8GHz with 10 GB of ram. This is the best desktop I have ever had. It is fast and quiet. Right now I think I have close to 13GB of disk on it (both internal and external). I also dual boot it with MacOSX 10.8 and Windows 7 (for a couple of games)
  14. Apple MacBook Pro 2.8GHz iCore7 – the replacement for the one that died above. It is hands down probably 4 to 8 times faster than the 2.0 one that I had before.
  15. Sun V20z – Used to run VMware ESX 3.5 with a Sun T3 fibre connected Disk array. The V20z is fully loaded with processor (2) and ram (16GB). One loud machine…
  16. IBM X3550 – Dual Quad Xeon with 8GB of ram. Used to run VMware vSphere 5.0. Used it to play around with doing virtualization of my house servers. Unfortunately it is too loud to leave running 24×7, so it is only on when needed.
  17. HP XW8600 workstation – Dual Quad Xeon with 16GB of ram. This is my “production” VMware server at  home. It has 3 TB of disk it in and runs probably 11VM’s all the time. It was used to replace the noisy IBM one, and it is super quiet.

As for a list of operating systems I keep current with, it is many and with VMware it is possible to have “test” versions of everything sitting around which helps a lot. Basically the following is what I keep running:

  1. MacOSX 10.7 and 10.8
  2. Windows XP, 7, 8, 2008, 2008R2, 2012
  3. CentOS 6.3
  4. Solaris 10, 11
  5. OpenIndiana 151
  6. pfSense (freebsd)
  7. OpenBSD
  8. Ubuntu Linux

Well that is about enough nostalgia for tonight. Trying to think of other things to put back on the blog to start updating it more often. If you have any idea’s leave a comment (open for 30 days only to keep the spammers away..)

Home repairs, third edition

As a continuation to my other home repairs (part 1, part 2) this summer was no different. This year it was 2 major projects, the first was to repair the chimney, and the second was a new roof. First some pics of the chimney:

The finish of the chimney is a parge look for now. I will probably paint it some time later. The chimney cap was a poured concrete one as the original had completely deteriorated.

 

Next up is the roof, as you can see in the picture above, or not, there are black streaks going through it. So before it got bad, I replaced with with 30 year dimensional shingles..

 

 

All told it was around another $10,000 in repairs. Totaling over $30,000 in the last 3 years.

X-Plane 10 and the bugs I hate

Right after Microsoft said they would quit development on Flight Simulator, I started looking for a new sim to fly. One that came up was Austin Meyer’s X-Plane. Some key factors were that it ran natively on Windows, MacOS and Linux. Since I switched to using a MacOS Desktop, this was awesome as I didn’t have to keep booting in to Windows to use MS Flight Sim. So I purchased version 9 of it a couple of years or more ago. While it lacked several features that MS Flight Simulator had and I had become used to (I.e. a pretty nice ATC, lots of AI traffic, nice graphics, etc) it did have it’s own pluses, like running a little smoother and a little easier customizable.

One of the “big” things about X-Plane9 was that a full install was nearly 80GB in size. One of the big things I hated was that there was nearly to no airport buildings at the airports, unless you got a third party download where some one had recreated it. Granted this was cool as it allowed people to create some awesome replications (I did one for Morgantown, WV and Waynesburg, PA). But alas, for over 80GB of install you would have thought there would be the basic airport buildings or at least the terminals in it.. So while I still played with X-Plane, I found myself going back to MS Flight Sim just for the buildings and the ATC (sounds hokey, but it seemed “more real”).

So they finally released a new version of X-Plane, version 10 this year. The screenshots on the internet looked almost photo realistic. So I downloaded the demo, and it had one airport (KSEA) and it had buildings and all. So I was happy to see they had done that. There was also promise of a better ATC, which from some quick playing with the demo was better… So I spent the $80 and bought the full game. and about 6 hours later, I had another 80GB of X-Plane 10 installed (so now I have over 160GB just for version 9 and 10). This is where my “fun” left.

So it seams that the only airport that has the terminal and buildings (that I have been to so far in the game) is the KSEA. Every other airport is just the tarmac, runways, apron, and taxiways, no buildings what so ever. Another “peeve” is the AI traffic. It makes no difference where you are (little municipal airport to a international one) it seems like there will always be a 747, a little single or dual engine prop and what ever plane you are flying, and a 747 in the sky. I don’t know how many times I have changed to a new airport and the AI planes spawn directly on top or under me. It is hilarious to see a Boeing 747 try to taxi around KMGW and try to take off on a 5,000 ft runway.

Another stupid bug with the AI traffic is that I can go and file my flight plan (with the some times working ATC) and then start taxing to the runway. Every single time I have done this, there is already 2 planes holding at the runway, however one AI plane is ALWAYS half on the runway and half on the taxi way. This causes problems as it never freaking moves. So when another AI plane tries to land, it is told to go around because of the AI half on the runway. I sat at KJFK one day for over 20 minutes waiting for it to take off and it never did. I finally “drove” through it and took off. This of course pisses the ATC off and it constantly keeps telling you to taxi back to the runway. So much that the only way to stop it is to change the COM channel.

Since I am on a rant about the ATC as well, might as well mention that some ATC’s in some airports are on channels that you can not turn too. That makes it awesome to try to do anything. In addition the ATC never seems to tell you the frequency you are handed off to, which makes it impossible to do a full hand of to any other ATC.

I have also found that if you go to file a flight plan once you have taken off and screw up entering something in the route box, it will completely crash the application and you have to restart the entire program. Which I am not sure what changed between version 9 and 10, but version 10 takes forever to load. My machine is not a slow one either, with dual quad Xeon 2.8GHz processors, 10Gb of ram and a 3GB/s SATA drive with the application on it.

So until there is some more patches to fix some of these I will be going back to X-Plane version 9 and MS Flight SimX.

Blades and the true hidden cost

So as you may know by now, I am not a fan of “blade” technology, and rather despise it. One reason is that they simply are not as “powerful” as some larger systems. So what is this “true hidden cost”. What hardware vendors won’t tell you is that, while they think that their hardware is powerful and “compact form”, is that software vendors will almost rape you on the license cost. So lets look at a good example.

Say you are building a “cloud” (another word I absolutely hate, as it is just a buzz word some one made up, because “network” sounds so simple) for your company. You decided to go with the “all mighty blades” as that is the “current buzz” amongst the IT industry. So I buy a blade chassis from company X which happens to hold 10 blade’s that each hold 4 processors of 8 cores a piece and 128GB of ram (probably fictitious and not a real world blade). You also plan on implementing a virtualization hypervisor on your blades to build your “cloud”. On top of this hypervisor you will be using multiple different operating systems and various middle-ware. Sounds good so far right, just like any typical “cloud” environment. So now lets look at the pricing:

  • For the virtualization layer, we don’t care about CPU’s, just memory in use. So we have to buy enough licenses to support 10x128GB of ram. Again, not too bad, but as you add blades and/or memory your price goes up.
  • For the OS layer, this seems pretty simple, 1 OS license per Virtual Machine. Probably so far the simplest of all
  • For the middle-ware, now this is where the big bucks come to play. Different vendors license their software in different ways so here are some examples:
  1. Per VM, seems pretty simple, 1 license per VM. Easiest
  2. Per User, probably the second simplest algorithm, assuming you have an easy user base, i.e. all users are internal company users, or all are external users, etc.
  3. Per physical host, the most complex and costly. Why so? Well lets look in to this in more depth.

 

So in #3 above I mention that licensing middle-ware per physical host is the most complex and costly. Some people may be thinking that I am absolutely crazy by now but hold on to your seats and watch the money start adding up.

Say we have a fictitious product from vendor Y, the licensing of it is $100 per core of physical server, and the vendor of the software does not “recognize” virtualization.  So if we weren’t doing virtualization to license this product on one of our fictitious blades, that product would cost $3,200, as we would have to pay for all 32 cores in the blade. Still not too bad. But here comes the kicker, say that we created a cluster in our hypervisor that contained all 10 of the blades in our chassis. In addition to this, we have determined by usage that to be able to run Y in our environment, we only really needed a VM with 1vCPU and 2GB of ram. In a physical world, if you could find a server with one CPU, then we would only have to pay $100 for this piece of software. In addition if the vendor  Y supported virtualization you would only have to pay $100 to run it. However vendor Y is all about the money, so to run this one software package on your “cloud”, you would have to pay $32,000.

Wow, $32,000 vs $100 is 320% markup because vendor Y doesn’t “support” virtualization. But you are probably thinking, but hold on a second, I know that VM will only run on one blade at a time, why do I have to pay for all 10? Well because your VM has the possibility of running on any of the 10 blades at any given time. So you have to think of it sort of like auto insurance. Say you have 3 cars, but you can only drive one at a time (because you are only one person). But you still have to pay insurance on all 3, because there is a chance that you could drive any of them.

Does this make sense, hell no… But hold on to your seats because it gets even better. The vendor of product Y also make a hypervisor that does the same thing as another companies hypervisor. But the kicker is that if you use vendor Y’s hypervisor which has less features and abilities that vendor Z’s hypervisor, but does nearly the exact same thing (virtualize an OS instance), they will allow you to only pay for the 1vCPU license to run their product. This is just plain wrong, especially when you have already invested in vendor Z’s platform.

So with “cloud” computing being the current wave of IT, why can’t software vendors recognize that nearly 75% or more of most environments are already virtualized or moving to a virtualized “cloud” environment. If they can’t recognize this, then chances are people are going to go else where for their software needs. Because as your “clouds” get bigger the cost is exponential. To see that just use this as an example, the environment above is for a development. Once we go to production, say we have to have 10 chassis of blades, and there is a possibility of that one application running on any one of the 10 blades on any of the 10 chassis. So now instead of $32,000 you end up paying $320,000 for one little application, that only requires a 1CPU machine to run.

But what the hell does this have to do with blades? Well if you used larger hardware, you could decrease the number of physical servers that were in a particular cluster by consolidating even more. In the simplest term building up vs out. As an example say I could replace all 10 chassis of blades with 6 large servers (large meaning that they could hold 512GB of ram vs my max of 128GB of ram that my “blades” do). Now instead of paying for 100 blades with 4 processors of 8 cores a piece I am only playing for 6 servers of 4 processors of 8 cores a piece, a cost of $19,200, or 6% of the cost of using blades.

I leave it to you to see how much you would save by getting rid of your blades …

What happens in Vegas, should have stayed in Vegas

Last week, I went to VMworld 2011 in Las Vegas. The conference was great, 20,000+ people all there and focused on one thing, VMware and every product they offer. This was my first time at the VMworld conference, and hopefully will get to go again some time in the future. The main reason I went was because of the recently released vSphere 5 and seeing what all it offered and what all was changed. Needless to say, there are many cool new features that were added, I am only going to mention a few here, but the full list is available in this PDF.

The first cool feature is : Auto Deploy. Simply said, (wish they would have chose a different name) it is PXE boot of the vSphere image from a TFTP server, so no local disk is required to “run” vSphere. For example if you have a “shit ton” of blades and don’t want to have to go update and install all of them, just get their MAC address, setup the host in DHCP with a couple of DHCP options to tell it where to boot from and have the blade boot from the network. It will download the image from the TFTP server and run automagically. Once up and running all config is stored in vCenter 5 (a requirement!). So need to upgrade your hosts? Just reboot them after updating the image. A couple of notes for this, make sure you have logging set up to go to your syslog server, and that you set up the Dump Collector incase of a PSOD.

Another cool feature is: vSphere 5 supports Apple Xserve servers running OS X Server 10.6 (Snow Leopard) as a guest operating system. This is because vSphere now supports UEFI “bios”. Now “supposedly” this does not require Xserve’s (since Apple no longer sells them), but it “requires” them because of Apple’s EULA for use of Mac OS X.

There are many other features that have been upgraded, or are new.. Too bad the conference wasn’t a little longer, as the amount of sessions I wanted to go to were greater than the amount of time I had available to go to said sessions. (I.E. only one instance of a session and 2 sessions I wanted to see were at the same time.)

The Hands on Lab area was “freaking huge”. There were over 800 workstations set up where you could do 1 of 16 LABS (you could do more, just had to stand in line, I was only able to do 1 in the week I was there). Ironically each “lab” station was a Wyse “chubby client” that had dual monitors so you could rdesktop to some windows XP and servers to do the work. The HOL area, sort of reminded me of the CTF area at DefCon, a huge big room, with nearly no light what so ever and hundreds of thousands of screens.

The most interesting part of the conference is that they have grown so big, that next year they have to go to San Francisco to host the event, as there is no place in Vegas that is big enough to house them. This year it was at the Venetian with some spill over to Wynn. They also had the Sands Expo hall, which is connected to the Venetian. The “dining” room was 1.5 million sq ft alone, you could barely see from one end to the other.

I will have to say out of the many conferences I have been to by different vendors, I will have to say so far VMware has been the best. Some of the things that has made it stand out from the rest:

  1. Food, while not “the greatest ever” it was far better than I have had at other places. They gave us breakfast and lunch every day. In addition the break periods between sessions had different items every day. One day they had fresh hot made pretzel sticks with cheese and different sauces.
  2. Hang out area: Most conferences if there is “downtime” you usually end up either walking around or going back to the hotel. VMware set up a “hang space” where they had a basketball court, badmitten court, huge chess sets, fake grass to sit on in front of a big screen (like 20+feet) TV. A Twitter vMeetup place, where you could meet other people that you have met on twitter.
  3. Scheduled sessions. While I was skeptical at first on “pre-registering” for the sessions you want to attend, I think in the end it was a good idea, as it “guaranteed” your spot in the session as long as you showed up 3 minutes before it started. (There were gaps between end and start, so you really had no reason not to be there.)
  4. Group Discussion: in some conferences, I have seen “group discussion” be these “huge” groups where it ends up being a more Q&A session. VMware had group discussions, where there were maybe max 30 people in a room, each one had a clicker, and everyone voted on how the session went and it was a free form for questions. One of the best ones was the Oracle on VMware vSphere one. I learned a lot from that session.
  5. P.A.R.T.Y. : By far the best conference / vendor party I have ever been to. First was the food, you name it, they probably had it. I didn’t realize this till I had already ate a couple of slices of pizza. Then I saw a station where they were making fresh cut cheese-steak sandwiches, another was doing fresh made crab cakes. Like I said, name it, and it was probably there. In addition, a huge open bar (not that I drink, but it was there). So now that we got past the food, they had at least 4 different acts during the night. Two people doing fire tricks, then the openers was Recycled Percussion, which I didn’t realize who they were till I got back to the hotel room that night, but they were on the America’s Got Talent show, and previously had a show nightly in Vegas. The headliners were The Killers. They played for an hour and did all the “popular” songs along with some that I hadn’t heard before.
    This part of the party ended around 9PM. Which was the start time to the “after party” which was at the Venetian pool. I did not go to it, but it sounded like people had a bunch of fun there too.

So if you are still reading by now, you are probably trying to figure out the second part of the title “… should have stayed in Vegas”. Well, it seems that some time either on Sunday or early Monday morning I either sprained or got a stress fracture in my left foot. Needless to say, the 30+miles of walking I did, (cause my hotel was 2 miles away from the conference hotel, it is a damn long walk from Planet Hollywood to the Venetian even if you take the monorail when your foot it hurting like a Mofo) did not help it any. By the time I got home it was still hurting and I noticed that the top of my foot started to have some swelling and bruising. I just iced it on Saturday and Sunday, but as of today it was still hurting and didn’t seem to change much, so I ended up going to the doctor to have it X-ray’d. They said it didn’t show any fractures, but thought it was just a really bad sprain or a damaged ligament. So it is more ice, and a ankle air cast for a while. So that is what I “wish that it should have stayed in Vegas.”
