Error on a Youtube Page Shows Joking Programmers at Work

Instead of the usual 500 error, here’s what I got on an old Youtube upload page in my browser….

500 Internal Server Error

Sorry, something went wrong.

A team of highly trained monkeys has been dispatched to deal with this situation.
If you see them, show them this information:

Well it made smile, at least.


A very similar programming mindset to the one in Firefox if you type “About:config” into the address bar…

Automatic Metric Solves Wireless and Ethernet Network Issues

Automatic Metric: Windows 7 Laptop Will Only Connect to Huawei E5372 on UK Three Network, OR the Wired Home Network

Windows 8 Computers Work Fine Though!

Connecting Win7 to wireless and ethernet networks simultaneously

Problem link is shown in red

Automatic Metric is the place to be!

I have two networks essentially:

  • The “normal” wired network (gigabyte ethernet) that links all computers and printers through the Cisco Router.
  • The temporary mobile network that allows the PCs to connect to the internet while we are in temporary accommodation.  It’s a Huawei E5372.

The Issue

After setting up WiFi on the PCs, access to the Ethernet network disappeared – but only for the Windows 7 computer!!!

This meant that file transfers, backup etc between the machines, ceased, as well as access to the wired printer.   The printer worked fine when connected through its USB connection.  It has no WiFi.

In the same way, disconnecting the wireless enabled connectivity to the wired home network (Ethernet).

I searched and many forums had similar “fixes”, none of which worked. e.g.

  • Remove IPv6 leaving just IPv4 on the network adapters.
  • Remove network devices completely and re-install.
  • Try new or updated drivers.
  • Reboot each time.

However, two very small items appeared and worked for me!!  They are network settings, deeply buried and that I’ve never set before.

The Fix(es)

It’s the same in both Win 7 & 8.  Maybe even Vista, but as we know, Vista Means Death.  I did two places that got the Win7 machine to connect to the web through the Mobile WiFi dongle and to the home, wired and routed, network.

  1. Adapters and Bindings
  2. Automatic Metric

So Adapters and Bindings…

Network Adapters And Bindings

Network Adapters And Bindings (as seen in Win8)

  • Network and Sharing Center
  • Change Adapter Settings
  • Advanced on the menu. (Alt+N)
  • Advanced Settings
  • Adapters and Bindings tab
  • Set WiFi at the top

Oh Woe Is Me Again!

At this point, connectivity was still not restored, but it was an interesting setting, totally hidden in Win8!

 And Automatic Metric…

This is the killer setting that worked!!!  You need to do this twice:

  1. once for the Wireless network adapter
  2. and again for the wired Ethernet adapter
Here’s how
  • Network and Sharing Center
  • Network Adapter Wireless - Automatic Metric

    Network Adapter Wireless (Win 7)

    Click the first adapter, the one I need windows to use first.  i.e. The Wireless adapter.

  • Click Properties
  • Scroll down to “Internet Protocol Version 4 (TCP/IPv4) and select it.
  • Click Properties
  • Click Advanced
  • Uncheck Automatic Metric and put a low number (say 1) in the “Interface Metric” box
  • Click OK to save the settings changes.

Now do the second, Ethernet adapter.  Follow the previous method.  However, this time,

  • Network Adapter Ethernet - Automatic Metric

    Network Adapter Ethernet (Win 7)

    Uncheck Automatic Metric and put a high number (say 5000) in the “Interface Metric” box

  • Click OK to save the settings changes.

Conclusion

One commenter on the forum I saw (link to be done) said that just setting the order to 1,2,3 etc wasn’t sufficient.  Setting a large gap between interface metrics did the trick, which is what I did.

What Is Automatic/Interface Metric?

Well, you can do this search, or probably the best answer comes from Microsoft, here.

It sets the priority of network interface access, lowest number first, on an individual machine.

In my case, weirdly, the Windows 8 machines had no difficulty.  The single Windows 7 laptop fell over and caused me immense hair loss until I stumbled across the settings which I have never, ever touched in 17 years of computing and the web!

 

 

Windows Experience Index – in 8.1 – Where is it?

Strangely post on September 25th, 2013
Posted in Technology Tags: , , , , , , , , , , , , , ,

Introduction

Win8 Experience Index (also in Win7)

Win8 Experience Index (also in Win7)

Recently Microsoft announced  a bit of a climb down over its release of Windows 8.1 to MSDN developers (like me).  Their previous stand was for developers to get 8.1 at the same time as commercial release.

So I’ve had a look, installing it into a VirtualBox environment…

The focus of this article is on one difference, the Windows Experience Index, mine is shown in the screenshot in the top right.

Differences?

Win8 Control Panel

Win8 Control Panel

Well yes and no.  Apart from the much talked about “start” button (not) re-instatement, the control panel throws out some differences for sure (see screenshots)…

Win8.1 Control Panel

Win8.1 Control Panel

….. notably the Windows Experience Index (or Performance Indicator) (or Assessment), a Microsoft gauge of the “goodness” of your machine.

Well in Win 8.1, it’s gone!  See highlight…

Or Has It?

WinSat Usage

WinSat Usage -not all shown!

Actually, it’s still there under the command line…  All you need to do is add a switch (I chose ‘formal’ as it does the lot).

The actual file that does the work is called winsat.exe and it’s in the System32 folder.  Give it a ? switch from the command prompt and all it’s inner options and usages are revealed!  (see left)

So fire up your command line and run:

C:\Windows\system32\winsat.exe formal

…then watch the process stream past.

Results

There no nice GUI web report, of course.  The results are still there, tucked away (as they always were) as a set of XML files in the Windows directory.  Go to:

C:\Windows\Performance\WinSAT\DataStore

Win8.1 System Assessment Files (cmd process finished in background)

Win8.1 System Assessment Files (cmd process finished in background)

..to find them.  The screenshot right shows the files I’ve just created and you’ll see that the process has just finished in the Command Line window and that it took 2min 49.59 secs to run all the tests.

Examining Results

WinSat Win8.1 CPU Results

WinSat Win8.1 CPU Results

Running all assessments has produced 7 files.

The screenshot here on the left shows the end of the CPU one.

The time it took is plainly visible along with the plainly poor CPU assessment (well it is in a virtual environment after all!!)

Conclusion

Windows Performance Index is not dead and buried in the new Windows 8.1 – it’s only been buried.

Synology – Better Than Most Backup Solutions for Me!

What is the Best Backup for Windows in a Small Home or Office?  (SOHO)

This is the question I asked myself over two years ago.  At the time I recommended the SynologyDS210j and I still would if they made it!

It’s now been replaced by the DS212j, that’s it on the left.

This though, is essentially the same as my old one and in fact, in appearance it’s the same.  My DS210j has functioned perfectly for well over two years.  It just sits there, quietly doing its own thing and has never let me down.

I’ve uprated the internal operating system (called DSM) several times and it now stands as version DSM 4.2-3202.  Synology have said that this will be the last incarnation of this software and that there’ll be no further versions for me on this hardware beyond version 4.

If I was buying now, I’d just buy the latest version.  It does everything anyone would want, is quiet and reliable.

New Kid? The D-Link ShareCenter 2 Bay….

Well nearly, but it’s not for me.

My friend has just bought a D-Link ShareCenter 2 Bay Cloud Network Storage Enclosure since they didn’t want to spend so much…

It’s less than half the price of the Synology and tomorrow evening, I get to set it up!

The specifications, included software, and operating system functionality are almost identical to my Synology.  You know, stuff like media server, web server, iTunes server, backup drive, security camera monitoring, the list goes on..!

  • The reviews, however, say that it is noisy, though my friend says this isn’t an issue since it’s going in a cupboard with the router and internet gateway. It does seem to have a smaller fan than my little white cutie, so that could be it.
  • Some reviewers had difficulty setting it or its software up.  Well actually, I’ve had a few difficulties myself with the DSM software from Synology – if you’ve not done things like this before, it can be difficult and confusing.  It’s not Windows after all!

So, watch this space.  I’ll get back later when it’s all done.

Akismet and Jetpack Issues, Stop Spammers and CloudFlare Save the Day

My Web Host Penalised Me Yet Helped Speed Up My Site

Introduction

shared web hosting

shared web hosting

This site used to be hosted on Site5, in Texas.  I had a shared web host account, about the cheapest there is on Site5 though by no means the cheapest around (I’ve had experience of really cheap hosts….).  It worked alright, site management was good.  Then, I got hit by spammers.  Twice.  Big time.

Each time, this slowed the site down, made life hell for other shared accounts, especially when I introduced WordPress plugins to counter this.

Naturally, Site5 advised me to stop the hits or they’d pull my account (they’d already temporarily disabled it).  They advised me to cut the plugins, using GoDaddy’s plugin testing tool, WordPress Plugin Performance Profiler (P3).  So I did this, and after some trial and error, got the running processes down.  Of course, I lost a bit of neat functionality.

Testing Times

Apart from internal WordPress testing, it pays to test your site as if you are someone else somewhere else.  Pingdom have a set of tools that does just this, testing from various global locations and I can recommend it.

Result!

I used an iterative approach, testing various combinations of plugins and systems to end up as being in the top 8% sites for speed in the world!  Not bad for free is all I can say!   You’ll see in the screenshot above, that 92% of websites are slower than mine….   So is it really free?  Here goes…..

Paid For:
  • Web Hosting.  Shared.
  • My domain registration.
Free:
  • WordPress and all the LAMP functionality
  • WordPress plugins
  • CloudFlare

Automattic Issues

WordPress (which this site uses) is built by the Automattic team and naturally have expanded over time.  I’ve used their plugins for many years, Akismet from the off, which is a comment spam blocking system.  Latterly, they came out with Jetpack, where they say,

Supercharge your WordPress site with powerful features previously only available to WordPress.com users.

Jetpack is a WordPress plugin that supercharges your self-hosted WordPress site with the awesome cloud power of WordPress.com.

P3 Selected Output

P3 Selected Output

This is all well and good, except when I tested it using the P3 plugin profiler, Jetpack was the biggest drag on everything!   The worst part of it, was that actually, I was only using a small part of its features and it was still the biggest suck on performance.

  • I didn’t use Carousel for photos since I had an old solution, NextGen Gallery, that I’m loathe to change.
  • The comments system mucked up all other comment plugins, grabbing all for itself (a bit like Microsoft here!)
  • I used the stats, and that was about all, yet they were very slow and not that informative, actually.
  • Nearly all the other stuff I looked at, tried and ditched for similar reasons.

So much for the awesome cloud power.  On top of this, you’re now supposed to pay for parts of Automattic’s offerings, like Akismet, the comment spam blocker while a major offering of theirs was actually slowing my site right up!

What Did I do?

Change host!

Well not initially, actually, though the heavy-handed Site5 approach got my ire a bit I must admit.  I did do loads of tests with a host of caching, anti-spam and page load improvement plugins first…

Vidahost

Vidahost

I now use Vidahost in the UK.  The site is faster to manage (along with my others) since the servers are in the UK with me, and it’s cheaper, providing almost the same functionality and tools as Site 5.  I took the opportunity to clean out a few dead files in the process, but essentially, all was moved, database and files.  The lot.  Just twiddled config.php and the .htaccess file a bit.

did worry that my American visitors, who are actually in the majority, would  suffer slower speed and thus I’d get hit in Google rankings, but hey, wait for later…!

I got it all working and as part of the whole “thinking” process since the very first warnings from Site 5, I’d been looking for better things.

Looking at Things Closely

  • I like Related Posts.   Related Posts plugins do just that.  I love the idea of pulling out meta-data relevant stuff from a website.  Site 5 had said, as have others on the web, that this sort of plugin makes big hits on a site.  Some of them really do!  I use  YARPP, with a limited subset of features enabled which cuts down processing.
  • I also like Andrew Ozz’s Shutter Reloaded which shows images nicely.   I also like his post editor, TinyMCE Advanced, it being the best of many I’ve tested over the years.
  • I like NextGEN Gallery having used it since before WordPress got all image fancy.  I haven’t got time to fiddle with thousands of photos now…
  • I’d like some statistics within WordPress.
  • I’m not that interested, any-more (though I was) in Social Networking sharing features.  Truth be told, if someone wants to share, they will.
  • I’ve read a lot on image improvements.  I’ve always shrunk images manually before uploading using the excellent IrfanView application.  But during this enforced research, other things like sprites and delayed image loading popped into the equation.

So I like certain plugins or functionality.  I try and use the one that works best for me.  Too many plugins make a big hit on the server and thus website loading.

Caching

A way round this is caching.  e.g. If a post is created and has related posts clagged on the bottom using YARPP, then the post is cached and YARRP is only running once.  How and where the caching is done is the crux of the issue…

Site 5 suggested W3 Total Cache as a better alternative to Wp Super Cache,  which I’ve used for years.    Naturally, I’ve tested this and my conclusion was that it could be fast, and it was fast for a while, but over time on each of my sites I got issues around lock-ups and the huge and complex caching system around files, databases and sprites.  This list is long.

I’ve also tested various database query caching plugins likewise over the years.  W3 Total Cache incorporates this method too, but ultimately, it made too much work for not a lot of difference IMHO, since I’m lazy.

However, it did point me to one thing!  CloudFlare.

CloudFlare

CloudFlare Admin1

CloudFlare Admin1

Ah.  The power of the cloud is back!

Not only that – it works!

CloudFlare Admin2

CloudFlare Admin2

You re-direct your DNS at your domain registrar (joker.com in my case) to CloudFlare’s DNS servers, set up the site malware protection level you want – then after a few hours your whole site is cached and protected.  Best of all, it’s free for a little site like this!

In fact, using CloudFlare speeded everything up even before I got caching going again…

Further Plugin Work

Now, I went back to Wp Super Cache from Doncha and it all works fine.  Site speed good.  I then ditched Jetpack after testing it again.  It really does interfere with all comment plugins, and I really like this comment one as do people who comment here:

  • U Extended Comment

It works great and does everything I want.  So Jetpack, it’s bye bye.  Take all your fancy commenting system, your stats, your social media and fancy image handling.

But What About Comment Spam?

Stop Spammer Results2

Stop Spammer Results2

Stop Spammer Results1

Stop Spammer Results1

I’ve found the best solution is a plugin called Stop Spammer Registrations Plugin.  It needed a bit of fine tuning and a re-activation of Akismet to whip out a few wisps of spammer, but it works and seems to trap and report more spammers than ever Akismet did alone.  Akismet, by itself, does the commenting bit in tandem with the plugin, rather well.

Registration Spam

SABRE Results

SABRE Results

Unfortunately, during testing, a few unwanted visitors managed to register on the website.  They can’t do real harm since I use the lowest role level at registration time.  So I re-enabled SABRE and since then, no more unwanted visitors.  I’ve tested SABRE as a visitor and the settings I’ve chosen are just about right – I’ve had issues with it previously when it blocked registration!  But reducing the feature set and re-uploading a clean plugin fixes that.

CloudFlare and the CDN Issue

I toyed around getting a CDN to host images.  But they (can) cost and anyway, I’ve gone off Amazon and others because of their anti-Wikileaks actions plus they don’t pay UK tax…

Delayed Image Loading

However, in the course of my reading, I found that images can be loaded just as the page comes into view, which speeds up page loading, and as a consequence the perceived nippiness of a site.  The plugin BJ Lazy Load does this for me and works brilliantly.  Check this last post about Australia which has a lot of medium sized images to see them pop into view!

Delayed Javascript Loading

I use two plugins that handle this end of the issue around JavaScript.

Statistics

WP SlimStat1

WP SlimStat1

Well, Jetpack is gone.  I won’t be using it unless some serious improvements are made, it being the prime reason for the server load that brought me to this position in  the first place.  As soon as I disabled it (and simultaneously blocked all comments to the site, which isn’t the best thing, this being a blog after all), all server loads went away.

I now use SlimStat and it works very well.  I’ve tried many over time, including Google’s analysis tools, my webhost’s stats tools, Wassup and more, but for now, this is it.

Conclusion

My site works pretty fast and is pretty protected from the bad guys.  I actually still use more plugins than what is usually recommended – 50 is a huge lot according to web gurus and sages.  Currently there are 31 in active operation with 8 inactivated.  I love trying new ones, it’s like that, that’s just the way it is.

The delayed image loading is particularly apparent on a post with a lot of images, say this recent one.  The post loads fast and you see the first images load, and as you scroll down you’ll see other images appear with a slight delay.

All the other stuff is incremental improvement, with the biggest, by far, being the free CloudFlare service which I cannot recommend highly enough.  It’s a no-brainer, go and do it?

My Full List?

These are the plugins currently running that help my site work.  Many are for security, which demonstrates the state of play versus the bad internet guys full well.
