Did the cryptocoin bubble burst?

I mentioned a little while back that you can still get into cryptocoin/cryptocurrency mining by using MinerGate, and mining alternative coins. The question now is, should you hold off on mining for a while?

Back when I wrote that, Bitcoin and Ethereum, two of the biggest cryptocoins available were at all time highs! People who got in at the ground level, and left their money in saw incredible returns and probably ended up as millionaires! It now looks like that bubble might be bursting.

I'm no expert of course, but looking at these charts from Coinbase, certainly doesn't look good to me!

This is Bitcoin's loss since last month:


This is Ethereum's loss since last month:




Litecoin has gone up a little since last month:


However, Litecoin has dropped since last week:



Again, I'm no expert, but it seems that if you haven't already been on the cryptocoin boom boat, chances are you've missed it. If you are looking to get into cryptocoin investing, you may want to wait until after the market bottoms out first, and buy when it's really cheap.

What do you think about this? Are you a financial expert? Do you agree? Do you think that these numbers are nothing to be concerned about? Let us know in the comments.

Goodbye Photobucket! Hello Imgur!

Some of you may not have realized it. I mean, I just learned of it myself a few days ago, but if you host any of your images on the legendary image hosting site, Photobucket, chances are your web pages are all messed up right now! That is because Photobucket is no longer allowing free accounts to embed images on third party websites!

From The Register:
Photobucket is cracking down on people embedding on third-party websites images it hosts, until now, for free. 
The photo-slinging internet elder now says that anyone who wants to use its service to display photos it hosts on other pages – such as signature banners in forum posts – will now need to open up their wallets and plop down $399.99 a year for a subscription plan. 
The new policy will be particularly annoying to longtime users who have relied on Photobucket's 14-year-old service to host the images they use to place images on forums or in blog posts. 
Cheaper plans, including the free account option, will no longer have an option to allow third-party hosting.

If you have visited Bauer-Power, or my other blog Bauer vs Wild in the past view days, you have seen this annoying image plastered all over the place!



Of course the image above doesn't tell you that in order to get third party image hosting working again, you need to fork over $400! That is completely ridiculous, especially for private bloggers like me. I don't even make $400 a year with this little hobby. There is no way I'm going to pay that just to host images.

If they had said they wanted $20 per year, I might have considered it, but $400? They can shove their service up their ass! I'm not going to pay that!

I've decided to move the small amount of pictures I was hotlinking from Photobucket over to Imgur. Now my site doesn't look like complete shit! If you are looking for an alternative to Photobucket, you should check out Imgur too. You can even login with your Facebook, Twitter, Google or Yahoo accounts!

Besides just having really cool free image hosting, Imgur is also a pretty fun community to be a part of, where people share news stories, memes, jokes and all sorts of stuff. Here is a little history on Imgur from their About Page:
Imgur was founded in 2009 by Alan Schaaf in his Ohio University dorm room as a simple, no-limits platform to share images online. 
With the launch of the homepage gallery, Imgur gave its community the power to refine its many images into a showcase of the freshest, most interesting and popular images on the web. These images can be hilarious, cute, inspiring and informative. From stories of personal transformation to current events, pop culture, memes and more, Imgur has an image for everyone. Of course, there are plenty of cute puppies, too. 
Each month, images on Imgur are viewed across the Internet billions of times. It is currently ranked one of the top 50 largest websites worldwide.
Some people have complained about not being able to get their images off of Photobucket. I didn't have an issue myself. When I clicked on my images within Photobucket, it was replaced with the above disabled 3rd party hosting image. However, when I pasted the direct link URL for the image in the browser, the original picture shows up, and I was able to right click on it and download it. From there I could upload it to Imgur.

Suck it Photobucket!



Did you get screwed over by Photobucket's business decision too? Did you switch to a new image hosting service? If so, which one? Let us know in the comments!

Coming Soon: FREE Wildcard SSL Certificates!

I was just made aware of some really awesome news for those of you that value your online privacy! I wrote in the past about free named SSL certificates from StartCom. That was pretty cool, and I have used plenty of their free SSL certificates, but another group is about to "one up" them!

Let's Encrypt announced that they will begin offering FREE wildcard SSL certificates starting in January of 2018!

From their press release:
Let’s Encrypt will begin issuing wildcard certificates in January of 2018. Wildcard certificates are a commonly requested feature and we understand that there are some use cases where they make HTTPS deployment easier. Our hope is that offering wildcards will help to accelerate the Web’s progress towards 100% HTTPS. 
Let’s Encrypt is currently securing 47 million domains via our fully automated DV certificate issuance and management API. This has contributed heavily to the Web going from 40% to 58% encrypted page loads since Let’s Encrypt’s service became available in December 2015. If you’re excited about wildcard availability and our mission to get to a 100% encrypted Web, we ask that you contribute to our summer fundraising campaign
A wildcard certificate can secure any number of subdomains of a base domain (e.g. *.example.com). This allows administrators to use a single certificate and key pair for a domain and all of its subdomains, which can make HTTPS deployment significantly easier.

This is kind of a big deal. If you want to secure more than one website or service with TLS/SSL then getting a bunch of named certificates can be a pain to manage. Plus, many certificate authorities charge a pretty penny for wildcard certificates, so it prices many small businesses and groups out of the encryption market!

Having a non-profit group, like Let's Encrypt, issuing free wildcard SSL certificates encourages more people to use encryption, and makes it easy!

What do you think about this? Are you going to give Let's Encrypt a shot? Let us know in the comments!

What is SNI?

I felt like writing this post because I deal with this question quite a bit at my company. What is SNI? Well, in short, SNI is an acronym that stands for Server Name Indicator, or Server Name Indication. Wikipedia describes it as:
Server Name Indication (SNI) is an extension to the TLS computer networking protocol by which a client indicates which hostname it is attempting to connect to at the start of the handshaking process. This allows a server to present multiple certificates on the same IP address and TCP port number and hence allows multiple secure (HTTPS) websites (or any other Service over TLS) to be served by the same IP address without requiring all those sites to use the same certificate. It is the conceptual equivalent to HTTP/1.1 name-based virtual hosting, but for HTTPS. The desired hostname is not encrypted, so an eavesdropper can see which site is being requested.
In a shorter, more concise explanation, SNI lets us bind multiple SSL certificates to one IP address. In the past, we used to have to bind an SSL certificate to a single IP address, and any additional SSL certificates would require their own IP address.

This is a real problem when you can see that IPv4 is running out of addresses! It also became a problem if you wanted to host multiple websites on a single web server. One web server might need eight or nine IP addresses to server up eight or nine different websites!

The reason I get asked about this a lot is we have several clients whose applications don't support SNI, and when they try to connect to our API that requires SNI, they get some sort of SSL error. We have a workaround for those clients, but I still find myself having to explain this to many of the people I work with (Often several times over).

The reason the clients that don't support SNI get SSL errors is that their application isn't smart enough to tell the web server which website they are trying to connect to by using the hostname at the start of the handshake process. Because they can't tell the web server which site they are trying to connect to, they are presented with whatever is the default certificate, which doesn't match the hostname, so they get a handshake error.

I see this a lot with Java based applications, but occasionally I see this with custom .Net applications as well. I guess this depends on if the developers have taken into account SNI or not.

I also see this a lot with DataPower/WebSphere clients, but DataPower can be configured for SNI. Check out this video:




All modern browsers support SNI, and in my opinion, all modern applications should too. If your application does not support it, then I would suggest lighting a fire under your development team's collective ass, and have them update your application to support it!

How To Get Rid of Boxelder Bugs... Seriously!

This isn't really technology, computer or software related, but I thought I'd share this with you anyway since it is something that has literally been "bugging" me for the last two years. That is that I've had a huge issue with Boxelder bugs all over the front of my house! They weren't there when I moved in three years ago, but they took up residence last year and never left apparently!

Looking on YouTube, I found this video that tells you to use liquid dish soap and water on your siding because the Boxelder don't like it apparently:




Well, this technique did get them off the siding, it did NOT get them off my sidewalks or bushes around the front of my house. It did not solve the problem!

Well, today I had enough and decided to get something that would solve the problem. I bought some Spectracide HG-95830 Triazicide Insect Killer for Lawns & Landscapes Concentrate, Ready-to-Spray and attached that sumbitch to my garden hose!

I let loose a torrent of water and death all over the front of my house, on my sidewalks and in the plants around the front of of my house. Hordes of Boxelder bugs were covered in the Triazicide spray and slowly met their inevitable doom!

The ready to spray version is the best in my opinion because it hooks to your garden hose and allows you to spray a large area quickly.

The Spectracide website even lists Triazicide as one of their solutions to kill Boxelder bugs! Boom! Suck on that you nasty bugs!

If you have Boxelder bugs all over the front of your house, ditch the dish soap, grab a hose and hook up a bottle of Triazicide to it and unleash hell! You can thank me later!

mdadm: /etc/mdadm/mdadm.conf defines no arrays.

One of the most annoying things about Ubuntu 16.04 LTS server edition is that every time you go to run updates, you almost inevitably get hit with this message:
mdadm: /etc/mdadm/mdadm.conf defines no arrays.
It turns out that this message is completely benign and you can ignore it, but that doesn't make it any less annoying right? Hopefully they get that worked out in Ubuntu 18.04 LTS next year. Until then, there is a quick way to fix it.

Just open /etc/mdadm/mdadm.conf with your favorite text editor and add the following lines at the bottom.
ARRAY devices=/dev/sda
Save the file, and that's it. No more stupid error.

If you didn't know, mdadm is the Linux software RAID software. If you are running Ubuntu in a VM though, chances are it is not going to have a software RAID to manage.

Get into cryptocurrency mining the easy way with MinerGate!

You may be asking what is cryptocurrency. Well, Wikipedia describes it as:
A digital asset designed to work as a medium of exchange using cryptography to secure the transactions and to control the creation of additional units of the currency. Cryptocurrencies are a subset of alternative currencies, or specifically of digital currencies.
Bitcoin was the first one out, and if you didn't know, as of the time of this writing Coinbase is reporting that 1 Bitcoin is currently worth $2,277.22! That's a lot of money, and it's value has only gone up over the last few years.

If you are unfamiliar with Bitcoin, I made this Tech Chop video a few years ago to talk about it:



So now you get the idea right? Well, Bitcoin isn't the only name in the cryptocurrency game. There are tons of other ones like Monero, Litecoin, FantomCoin etc. Almost too many to count. The problem with Bitcoin, even though it's the most mainstream of them is that mining it has really lost it's profitability. In the early days it was fairly easy to mine Bitcoins, and therefore the guys that got in early have made a ton of money by now, but that ship has sailed. That being said, since there are other cryptocurrencies, those of us late to the game still have a chance!

Introducing MinerGate!

From their page:
MinerGate is a mining pool created by a group of cryptocoin enthusiasts.

It is the first pool which provides service for merged mining. This means that while mining on our pool you can mine different coins simultaniously without decrease of hashrate for major coin
With MinerGate, you can easily mine other types of cryptocurrencies and transfer them to a digital wallet that you can use to cash out to dollars, or exchange for other cryptocurrencies like Bitcoin.

A great free online wallet, that supports many cryptocurrencies that I recommend is Cryptonator. Cryptonator also lets you easily trade between currencies. If you are in Europe, it's also good to cash out to fiat currency like Euros.

If you are in America, I recommend converting your alternative cryptocurrencies to Bitcoin or Litecoin with Cryptonator, then transfer that to your free Coinbase account when you are ready to withdraw your money to dollars. I say that because a lot of foreign Bitcoin exchanges don't play well with American banks, but Coinbase does!

If you are new to cryptocurrency/cryptocoin and want to try out mining and see if it's right for you, then in my opinion there is no easier way of doing it than with MinerGate.

For those of you that have been doing this for a while, what other mining tools or programs do you recommend? Do you use MinerGate yourself? Do you like it? Let us know in the comments.

[EDIT] I found that it's actually easier to transfer your mined currency from MinerGate directly to your Coinbase account using Changelly! With Changelly, you can transfer any type of supported crypto-coin directly to any other type of crypto-coin. For instance, I just transferred my XMR (Monero) to my Litecoin wallet on Coinbase! Boom! Easy!
