Digital Insights: Computer Tips & Tricks

So you have a word document that has a blank page after table on the previous page. If you place your cursor on that page and press backspace several times but nothing happens it means you have a paragraph mark inserted after table which lies on the bottom paragraph preventing you from deleting that page.

To see whether an empty page has paragraph mark activate pilcrow menu (see below)

Paragraph mark looks like this

Select this paragraph mark (it should be highlighted) and start reducing font size from let’s say 11pt to 1pt. This trick makes paragraph mark smaller on the empty page and by some point it should jump back on the previous page under the table. When this happens empty page in word 2007 disappears

If this doesn’t help try one more trick. Select paragraph mark like previously and right click select paragraph properties. Indentation and spacing should be set to 0pt

Write in the comments if this helped you to delete the annoying empty page in word document.

You have to be careful when placing javascript objects in a webpage. Latest Google doodle buckyball has a major impact on CPU load when you try to spin it. Bellow is a screenshot showing average load on one of the core of my i7 CPU. It uses more than half core power to animate.

i7 cpu load

After a while firefox RAM usage skyrocketed to more than 1,5Gb all thanks to this buckyball. I wonder how badly older computers that don’t have powerful processors will be slowed down. Not so long ago another Google’s doodle with pacman game also caused a lot of trouble for people who just wanted to use plain search and nothing more.

It would be nice from Google to have the option of opting out from such doodles in the future.

If you check your site DNS parameters with intodns.com and see error with Recursive Queries that says:

I could use the nameservers listed below to performe recursive queries. It may be that I am wrong but the chances of that are low. You should not have nameservers that allow recursive queries as this will allow almost anyone to use your nameservers and can cause problems. Problem record(s) are:

If you have your own VPS and Bind installed you can fix this issue by doing those steps:

1. Login to your webmin and go to Servers->BIND DNS Server
2. Select Miscellaneous options and there tick “Do full recursive lookups for clients?” to NO
3. Apply configuration or just restart Bind for changes to take effect

You can also disable recursive queries by manually editing /etc/named.conf file, just put directive “recursion no;” without quotes in options part:

Restart Bind server and reload intodns.com to check your site again and see that now it is correct.

Pretty much every site where you have to register using email declares that “we hate spam too”, “we promise not to spam you” and similar promises. But your email inbox is still full of fake cialis offers (I don’t even bothered to search the google what it is used for). So it’s almost impossible to identify which sites are collecting your email or selling to spammers because of course they never use the domain name on where your registered.

But here are the good news for Gmail users. Gmail does pretty good job identifying spam emails but I’m about to tell you 1 trick how to identify spammers. It’s interesting to know which sites are using spam methods or selling your email. For example if you detect that new online shop use your email for spamming then you will know it’s better to keep your money for other e-shop. Read the rest of this entry »

Different hosting providers have different speed. Site loading speed is very important factor because of 2 reasons:

1. Hosting speed directly correlate with people’s patience. Do not expect someone to wait until your site opens after 20 seconds. Many visitors will not want to look around your site because your pages are loading too slow.
2. SEO. This one is quite fresh. Google announced that in 2010 loading speed will be one of the factors that determine your position in Search Engine Results Page. So those websites from overselling hosting providers will suffer from slow loading speed.

How to compare hosting speed?

There is one quick tip to measure the speed of the website. You don’t need any programs to install. Read the rest of this entry »

Writing important essay or other text and want to autosave? Word 2007 has this feature. Unfortunately default autosave time is set to 10 minutes. It could be not enough for some people so it’s better to increase autosave frequency.

• Open new Word 2007 document and go to STart->Word Options

• Go to save tab and here you should see the field to input desired time in which Word2007 would auto save your opened documents.

In  this window you can also change autosave folder location to desktop. It would be easier to find instantly the recovered document.

Finding good freeware software can be tricky sometimes, because many shareware programs position themselves in search engines as “Free to download” and you can download only trial version of the program which has limited features.

Recently I had to download a couple entire websites for offline browsing (because they were shutting down) and was searching for a decent program that can download all website html and other type of files making original file structure. I searched in Google for a bit and found “SurfOffline Professional 2″ which could download entire site in a simple wizard style process. However there is a price tag from $39.95 to $120. And it’s no use spending money on software that you will use once. Read the rest of this entry »

Today various sources reports of a massive hotmail login information leakage on the web. The number of exposed hotmail accounts rise from 20.000 to even 30.000.

How to know if your hotmail account is hacked? Well there’s no universal technique to know that, but keep in mind that the infamous list contains primarily if not all accounts beginning with letters a and b. So it seems only a part of this list leaked into public.

Accounts ararat973@hotmail.com and blando2713@hotmail.com where the first and last usernames in a list.

Having in mind that it was not a hack in Hotmail system but more likely some gathered login  information via phishing or other web 2.0 applications which ask to enter your email address and password in order to do something (e.g. check who has blocked you in msn messenger and so on).

Another good thing would be to change the password to be on the safe side and not loose your privacy. Also don’t forget to check in Google your full email with quotes: “your@email.com” as it may show the locations where your email name is exposed and one of them might be that list with hacked Hotmail accounts.

Just a quick note to myself and others who experience a problem of WordPress showing only one entry (post) in category view.

At first I thought it was related to my theme, because I often edit in for various performance tweaks, but even changing through default WordPress themes the problem persisted and only one entry was showing in category although it obvously had more than one post in it.

So I started looking in my WordPress configuration and found that in Settings-> Reading sub panel it was an option called ” with value equal to 1. So I changed it to 5 and refreshed the category page. Sure enough it was it, now there was 5 entries displaying in my category.

So if someone else is experiencing this issue, at first check that parameter in your wordpress backend to save some time searching for problem in theme files.

By the way, the problem was on my other blog, but you can check some categories on this blog too :)

Today after coming back from summer holidays to my dorm room I encountered strange WordPress login problem where I couldn’t login to all my WordPress instalations on Hostgator hosting (404 error after providing valid login credentials). My first thought was that someone hacked the admin directory because there where no styling in login screeen,t just plain “cssless” login forms.

After searching for help on the internet I found nothing helpfull to my problem  so I decided to reinstall WordPress by uploading fresh files from clean WordPress setup folder and suddenly I saw .htaccess file in my wp-admin folder. Took a look and to my surprise I saw these lines:

deny from all
allow from xx.xx.xxx.xxx

A flashback came to my mind and the whole wp login problem dissapeared. These lines mean a WordPress admin folder protection. Nobody can access admin interface except user with the allowed ip. I have forgotten that I installed this security system on my blogs and paid an hour to solve that. Read the rest of this entry »
