No need to fiddle around with gcc toolchains, makefiles and whatnot.

This is one of the reasons I enjoyed developing with Visual Basic in Windows, and Gambas in Linux... I didn't have to muss around with Make files, etc... The system handled all that for me in the background.

I've switched to almost exclusively developing for the web now.

Yeah, it's odd. I'm asking myself why there are so much Java courses for students, but only a very few for C#. The .NET ecosystem is the best thing I have seen so far: Very well documented, very few bugs, runs on different platforms (ARM, x86, PPC..) and operating systems. Must be because Visual Studio wasn't always free. On the other hand, mono got its own compiler for many, many years now.

.NET is Windows centric and not appropriate to teach at university. It's also not nearly as common as Java. It's a good system for sure, but it is not academically apropos. Java is far from the only good option, but .NET is only appropriate as a side elective and as university should not be focusing on specifics, it's not really appropriate at all. If you learn Java, C# is a few days of work away from you.

.NET isn't so Windows centric anymore. Large parts of the framework are open source now and mono became a very good runtime today. In fact, I'm doing lots of stuff in C# on my ARM boards. Visual Studio is free for students and small companies. MonoDevelop is also ok. Not comparable in any way, but ok.

That's extremely recent and it's not really ported yet and Mono is... weak. I have high hopes, as I love C# and F# (heck, I wrote the certification tests for C#!!) will get wide adoption. But I'm not holding my breath.

You did? Hell, maybe I should get one just to see your test 😉

Yes, only one, not the entire series. One of the Previsor ones. I've written about a dozen certification exams over the years. I once had a job require me to take my own test in an interview. They were idiots. I told them ahead of time that I wrote it and then they nearly shit themselves when I scored the highest core ever. I wasn't sure if they thought that I was an idiot and could not pass my own test or if they thought I was lying. In either case, I wasn't too impressed.

I guess that I wouldn't want to work there anyway. I've always refused to take any test myself. "Thanks for the coffee, but no, bye". Got an offer from MS once, they sent me a test in a wordfile with some very, very stupid questions like "How many windows do you see when you open this developer tool?" REALLY, WHO CARES? Anyway, told them that if they send me that test by mail and I'm given like 4 hours for it to complete, I can easily cheat them by just using Google (or Yahoo). The lady on the other side didn't understand that.

Well I had to be somewhat impressed that they were paying hundreds of dollars per candidate to basically have me evaluating their candidates. But it also meant that I was way, way above what they were prepared to be working with. They wanted someone for a position that I would be hiring and mentoring. But you have to give them some credit for picking me as the person that they wanted evaluating people, even if indirectly 😉

Sounds basically where we are all aspiring to be one day

I didn't say introducing the #3 server caused this - I just mentioned that after I added #3 to the pool a while back, it had a similar event. The first time it happened, I let it slide, waiting to see if it would do it again. Yesterday at 10am, it had the same type of problem (isolated itself and rebooted) so today I decided I'd better pull it so that it wouldn't do that during business hours. At the time it only had two VMs running on it, and they weren't at all taxing the system.

They are all identical systems - Dell R610's with the same CPUs, the only difference is that #3 uses 48GB of RAM while the other two are 96 GB. I even upgraded all of them to the exact same firmware revisions before putting them into production and after testing them. #3 is just a bad egg. Not sure what the problem is, but it's powered off right now and I'll take a look at it if I get time to this week.

@BRRABill said in Linux: Symbolically Linking Files:

So to confirm, if I had first removed the /var/log folder, that command would have worked as I wanted it to, correct?

Correct. Since /var/log is a mount point for you, though, that is not as simple as deleting or renaming. You have to stop it mounting first. Then you can rmdir /var/log. Then you can symlink.

@Danp said in Stopping XenServer From Writing To A USB Boot Drive:

Here's one to watch from the Citrix forums: http://discussions.citrix.com/topic/379454-booting-xenserver-off-usb-safe/

P.S. Which one of you guys wrote this? 😉

That was me.

Those guys know the nuts and bolts of XS, though they aren't real responsive to threads all the time.

On ML that would have have 500 posts already and been forked 6 times. 🙂

Picked up my copy today.

So I haven't done this with XS7 as of yet.

The guide I followed on XS6.5 can be found here, everything is performed through the console.

Xen Orchestra has a guide that just uses the web console to create a local ISO SR.

@stacksofplates said in Best Syslog Server?:

I had an ELK server set up. I switched to Graylog. You don't need a specific forwarder, rsyslog just works. And you can get a pre-built VM to use. Kibana is an awesome tool, but just takes so much time to learn.

I prefer the agents. Much easier and more powerful.

It should be mentioned because it is an important approach, that for most of us, any talk of needing WordPress, cPanel and generic PHP web hosted would send us to providers like A Small Orange (that's who we use at NTG) to handle that for us. Fully hosted, full support and already tuned for around $5 - $10/mo. You get all of the load balancing, tools, cPanel licensing and such included. Hard to beat.

The FBI are not known for being very bright. Or technical.

They managed to get into the iPhone. Totally without the help of anyone else. Just imagine the party.

Except they hired someone else to do it 😉

@thwr That does work, I've done it many a time.

I miss my

Yeah, I like a dead OS 😕

Love you guys 😉

C? Maybe I should just **call_you_back? 🙂

@prcssupport said in Xfinity (Comcast) is rolling out a metered connection trial in Chicagoland and I am part of it:

I'm involved in a project in my town to start and expand a municipal network. Do you have any more info, links and stuff to help with that?

I was not directly involved in the planning or implementation of HCS (the second link above), but I participated in the community meetings and talked to voters and such to get it passed on the ballot. At the time I worked for one of the towns larger employers and was sick and tired of the poor service choices available.

I am sure you can contact HCS and eventually get put in contact with someone that was part of it all to give you more information.

Edit: Highland, IL is a bit unusual due to the fact that until deregulation forced it, the only place to buy electricity was from the city. Most towns do not maintain their own utilities. The benefit this provided to the fiber project was that the city already had rights to poles and easements to run the fiber.

Edit 2: Highland, IL was severely under served for internet. For telephones service, the ILECs kept selling the town around until it eventually ended up with Verizon, and they don't want it. The infrastructure was never upgraded over the years nor was the CO equipment. There is not not even any 15 year old DSL available, because there is no equipment in the CO for it.
For cable service, the town did get cable internet from Charter back in late 1999 along with all the other towns in the area. But like the phone companies, never upgraded the network afterwards. In 2007/2008 when the HCS project was still in meetings with residents trying to decide a path forward, Charter sent people to tell the residents what a huge mistake it was and waste of taxpayer money. But for some reason, the next month the town was swamped with Charter vehicles working on the lines and within months DOCSIS 2 level of service was finally available.

Just updated the cluster to 7.1

Option #1 up and running. Now to work on the OpenVPN part of the equation... 🙂

I have set this up but then ran into the problem of the OpenVPN port being blocked. Slightly hard to change once out in the wild.

On which end?

The remote end obviously. As I have full control of the server side.

@Dashrender said

So you never enter the key? and Windows 10 wasn't previously upgraded on this machine and then rolled back? i.e. Windows 10 has NEVER been installed on this machine before?

Hmmm, now that you mention it, maybe I did install Win10 on it before.

But I think I have done it before. On my own machine in fact.

I will retract until I am 100% sure. 🙂

I had a reason to set up a new VM today, and used a Windows 8 key to do a fresh install of Windows 10.

So I think it does indeed work.

It works as long as your Windows 10 media is r1511. Prior versions would not work or activate on an old key until updated to r1511.

Look in /etc/fstab and you'll see where the mount details are coming from. Pretty sure that your RAID array just has LVM on it.

All operating systems, including Windows, include the base kernel, shell(s) and support applications and, in some cases, extra stuff like Solitaire and such.

Each Linux distro is the same. It is a full operating system on its own and includes all the same kinds of things.

@BRRABill said in Remotely Accessing Desktop of GUI-based Linux Clients:

@scottalanmiller said

Linux Mint is a full distro, like CentOS, Fedora, OpenSuse Leap, Ubuntu, etc. It is a distro that focuses on desktop usage rather than server or mixed. But it is a distro. The desktop of Mint is Cinnamon, Mate, LXDE, etc.

How does a distro "focus on desktop usage", exactly?

Well, for example, it includes an office suite instead of a NoSQL database. It has a desktop instead of only a command line. Testing is done of desktop usage rather than server usage.

How do you test a limo differently from a tractor trailer?

@thwr Correct 🙂
