Reason #… I’ve lost count…not to use Microsoft.

Welcome all windows, and samba users. Please read badlock.org for why poor decisions have led to this day.

There is a known vulnerability with samba, please read the site listed. If time permits I will update this article with better info.  However, if you are running Samba the shame on you… especially the old version. I have not “had to run samba”, for anything in several years now.

Please read my article on using AFPd in linux to use it as a time machine  backup.  Works great! Or my preference is NFS on a LAN. 

Either way, I  hope this helps a few people. Please share the article if it helped.  There is a patch with CVE on the way according to their site.

Sincerely,
M

10yrs of Waiting! Finally got my Grados!

As many of my friends know, I am a bit of a audiophile. Not extreme, but I appreciate quality. I have had many headphones, from many manufacturers. Some very expensive, some very cheap.

I really like these headphones, as they give the best sound hands down; and they are very inexpensive.  Of course with anything you can spend more if you want.

So here are the Pros/Cons:

SR60e

 

Pros:

  • Amazing Sound
  • Low power Requirement
  • Comfortable

 

Cons:

  • Not the headphones you need if you are concerned about others hearing you.  It is very loud externally.
  • They are not what I would call “Pretty”, but I honestly consider that a Pro 🙂

 

Thanks to the family at Grado for an amazing product.  I am always willing to review any other of your products.

Be Careful with LetsEncrypt!

 

I must say, like a lot of people I love the idea of a free SSL Certificate.  So I thought this would be great for my site.  So I downloaded the LetsEncrypt package on to an Ubuntu 15.10 box.  The server was running Apache2, and was pretty much stock.  When I applied the cert to the site, it was super easy.  I was very impressed with the ‘–apache’ option.  I then updated my URLs in WordPress to HTTPS.  That’s it I was up and running in a few min.  I was pretty happy at this point.

Then, I realized it broke all of the other services I had on the machine that were public facing.  I had several.  Even ones with their own certs were breaking.  So I decided to remove it…. After removing it from Apache completely I noticed an issue.  All of my users that had been to the site; were getting redirected still.  Somehow it is keeping the redirct with the cert/data that is installed when the cert is installed from visiting the site.

Long story short, I had many people that thought my site was down.  I even moved servers; and it still happened. I tried clearing browser cache, DNS Cache on my MAC, from another IP. Finally after a reinstall (probably not needed, but quicker); I was able to actually load my site without the redirect.  I am sure there is something here I am not seeing; but to be honest I didn’t feel like spending all my time dealing with browser settings.

If anyone would like to let me know how they get around this I would like to know.

I hope this helps those who are thinking of trying out LetsEncrypt.  I am not saying its a bad product; or idea.  I love the install and the idea of it.  However, the practical implementation is not there yet.  For those reading this keep in mind that it is still in Beta as of this article.  So this might eventually go away.

P.S. – To those on the LetsEncrypt project, I appreciate all the work; and I hope you take this criticism positively. A good uninstall path is needed before I think this will go mainstream on monolithic boxes.  Maybe its ok with a 12 factor applications.

Sincerely,

Matthew Curry

Projects Page Added!

As requested, I have created a place for my projects on my site.  Please feel free to follow me as I work through them.  They are not projects that I am taking on professionally. They are completely for fun, and with no expectation or time limits.  That being said, I am a huge supporter of open source.

So in that spirit, I will be posting all functional code when I feel its ready to be used.  I am always open to ideas/suggestions.  Feel free to contact me via my Contacts page any time.

Quick Tip of the Day.

Not that I have them daily, but I might if I get a good response.

Have you ever tried logging into an SSH server, and get a weird error:

/.ssh/config: line 22: Bad configuration option: 342200202

This is a very simple issue but it can be a huge PITA if you can’t fix it quickly.  This is especially true for those of us that have to use an enormous amount of keys in our daily lives.  I know, I have a fairly simple config for SSH, but I still ran into this issue when I pasted a block of text in  ~/.ssh/config.  I opened the file with VI, and NANO. I was only able to get it to work when I removed the spaces before each line it complained about.  I then just put them back as normal, and saved.

It turns out, that copying from another place can have the spaces not interpreted properly. They are tabbed indentations actually.  Once manually removed they are replaced by a normal “space” in the code and it should work properly.  I hope this saves some time for some people.

 

Thanks,
Matthew D. Curry

 

Thank you all for the support

As many of you may know, my wife and I were hospitalized a day apart.  This was completely unrelated, and unexpected.  Luckily, I had family that was able to come help us out while we were in the hospital.  That, in conjunction with the many others that have shown support, and the hospital staff that helped us while we were there made it possible to keep us healthy, and together as a family.  I can’t show enough gratitude for everyone’s help.

Also, to my employer Welltok, who has been extremely supportive throughout the ordeal.  You have my deepest thanks, and I am forever grateful; and yours as an employee.

Again; thank you to everyone, even those not mentioned  (You know who you are).

 

Sincerely,

Top 10 Most Powerful Computers in the World!

As some people may know; I like to use the example of  “Out of the top 500, how many supercomputers in the world do you think  use [your OS here]?”.  I use this example for a reason.  Unlike conjecture, theories, and even “gut feelings”; it shows that the OS was chosen, and serious money and time were poured into it.  This shows that is it at least a player in the field, and can handle the serious levels of computing needed.  It also shows things like, tune-ability, flexibility with change, and a few other things that only the people working with their own projects will be able to tell.  We are not concerned with that, just that they are on the list; and why if it sticks out as odd to see why.

I am using the TOP500 Project for this information, and it does get re-evaluated often.  However, I will say this; just like in nature there will always be a pretty clear delineation when it comes down to who is the “Winner” in this space.  Or the most efficient/successful like in nature.

The reason I write this article is to show a certain group of people an example of the difference in reality versus what advertisements, rumors, and self-perception have molded in their minds.  I think it is a good exercise to show the affects of the budgets used to change our perceptions. A good example is the budget used by companies like Microsoft (over $2,000,000,000); and Apple (over $1,000,000 in 2013/2014).  This is just money, and perception however.  This will never affect real life numbers on performance, math doesn’t lie. Results and time are my favorite sources of information.  Its a simple concept, there are 1000s of ways to move items.  However, in our lives in this age of technology the wheel is still very much in use.   Its the best solution at the time…. (a small but powerful statement).

So in lieu of keeping you away from the data pron you came to look at:

 

Top 10 Super Super Computers - Nov 2015

Top 10 Super Super Computers – Nov 2015

 


 

Here is the actual breakdown by OS (as of Nov 2015), as I know that is what most people are interested in:

List_Statistics___TOP500_Supercomputer_Sites

 

I know some people are wondering where is Windows, or IOS.  If you will notice; even in the breakdowns by OS they are pretty much all Linux/BSD [Windows isn’t even a filter option on their site as of right now].  This list is more a list of flavors of Linux with a few BSD machines in the list.  You will notice, like in most of the lists done in the past; there is not a single Microsoft product on the list.  This is a very simple, and very important fact that way too many people make.  This includes everyone from the guy that fixes your desktop all the way up to the VP of Infrastructure.  They are all swayed by what they own, and the amount of advertising spewed forth at them non-stop. Keep in mind these people are generally more connected than the rest of the populous.  Thus, affected even more so by the ads.  Combine that with sales people/calls/pressures on support/etc, and you get smart companies ( I didn’t say large), that make really bad technology decisions.  I exclude myself from that ad loop; and look purely at statistical performance.   This is great for business; since you can eliminate a TON of costs; and licensing fees/etc that you would have if you went with something not on this list.
