My Way to Linux Certification [LFCS]

Valuable Tips & Help

Prior Register for Linux Exam & Tips

If you are complete beginner, I recommend to read some eBooks and take some online courses to pass the beginner’s level, and after Register for exam and then take more advanced online courses/eBooks especially for the Exam.

Exam done online [From your home/office room] from Chrome browser, embedded Terminal plugin … LF [Linux Foundation] setup a remote Linux server [CentOS 7 or Open SUSE 42 or Ubuntu 16.04 choice is yours/mine]…

I preferred Register for LFCS Administrator Exam of Linux Foundation because:

You do exam from Home without need to go to Exam center, but required have your PC screen monitored and having an external camera for monitoring room, by your exam proctor …etc . Also room must be quite and you/I being alone in the room…

I you want save some money: Register week LAST FRIDAY OF JULY – this day called System Admin day and MANY OFFERS EXIST for buying exam or bundles Exam + LFS201 Essentials of System Administration course… I saved $200 by purchasing an (offer) bundle 24 July 2017… I have one year to sit in my room online the exam…. and I have got a Linux course LFS 201 in the bundle… but I recommend you find and some other eBooks and courses … this never hurts.

You have one year to give the exam. Date/Time you/I define it. If you fail first time you have a second free retry…

Before register of exam or before get training from course LFS201 Essentials of System Administration, make sure you take and finished the Free course:

LinuxFoundationX: LFS101x Introduction to Linux

https://courses.edx.org/courses/course-v1:LinuxFoundationX+LFS101x+1T2017/course/

Exam is practice/performance based. You are given a server and a list of tasks to do on it… After you graded by automated system that checks the server you practiced on… after 3 days you get the result Pass or Not. To pass you need 74% score… During exam are permitted only server itself help resources like man(manual) pages, info pages and –help pages… you can Not surf the web for help nor have notes in the desk you work in your PC… during the exam.

From FAQ [extracts from LF Site]

6. How long does the exam last?

Once you launch the exam, you will have two (2) hours to complete the certification exam.

8. How can I study for Exams?

The Linux Foundation’s Certification Exams are performance-based, which means the only way to ‘study’ for them is to practice, practice, practice. The Overview of Domains and Competencies – listed in the Exam Details section of the webpage for each Certification (LFCS and LFCE) – provides guidance on the topics covered in an Exam. Candidates are encouraged to gain as much hands-on experience as possible in order to build mastery using the command line (since the Exam terminal does not use a Graphical Interface). Be sure to check out our Free Certification Prep Guide for more help.

Scoring and Notification

A score of at least 74% must be earned to pass the Exam.

Upon completion, exams are scored automatically and a score report will be made available within three (3) business days. If a passing score is achieved and other applicable requirements for Certification have been fulfilled, a notification indicating the Candidate has been successfully Certified will follow the score report.

Other Tips – https://www.linux.com/learn/tips-how-study-your-linux-certification-exam

There are different learning styles, and you’ll be more effective if you study in the way that suits you.

Taking the test immediately after the course it vital, he says. “Retention is a big factor.”

But if you’re going at it on your own, should you take the core competencies one at a time or look through them, then focus on your weakest areas? Again, that depends on your personal style.

Powers advises looking through the course material to determine whether you have the proper background. Then you can decide how to proceed.

He puts the success rate at about one in five for people who study on their own; at two or three in five for those who use online training courses that have to be completed in a set time period; and at 90 to 100 percent for structured training courses.

How to configure XAMPP to send mail from localhost?

lse June 2nd, 2017

How to configure XAMPP to send mail from localhost?

You can send mail from localhost with sendmail package , sendmail package is inbuild in XAMPP. So if you are using XAMPP then you can easily send mail from localhost.

for example you can configure C:\xampp\php\php.ini and c:\xampp\sendmail\sendmail.ini for gmail to send mail.

STEPS

in C:\xampp\php\php.ini find extension=php_openssl.dll and remove the semicolon from the beginning of that line to make SSL working for gmail for localhost.
2

in php.ini file find [mail function] and change

SMTP=smtp.gmail.com
smtp_port=587
sendmail_from = my-gmail-id@gmail.com
sendmail_path = “\”C:\xampp\sendmail\sendmail.exe\” -t”
3

Now Open C:\xampp\sendmail\sendmail.ini. Replace all the existing code in sendmail.ini with following code

[sendmail]

smtp_server=smtp.gmail.com
smtp_port=587
error_logfile=error.log
debug_logfile=debug.log
auth_username=my-gmail-id@gmail.com
auth_password=my-gmail-password
force_sender=my-gmail-id@gmail.com
4

ESPECIALLY For gmail please check https://support.google.com/accounts/answer/6010255 to allow access from less secure apps

SO AS GMAIL TO WORK IN THIS CASE… OTHER THAN GMAIL MAY OR MAY NOT HAVE [SIMILAR] SECURITY NEEDED SETUP.
5
Now you have done!! create php file with mail function and send mail from localhost.

PS: don’t forgot to replace my-gmail-id and my-gmail-password in above code. Also, don’t forget to remove duplicate keys if you copied settings from above.
6

For example comment following line if there is another sendmail_path : sendmail_path=”C:\xampp\mailtodisk\mailtodisk.exe” in the php.ini file

7
Also remember to restart the server using the XAMPP control panel so the changes take effect.

I can provide sample working XAMPP php.ini & sendmail.ini – download and compare if you have problems sending email….with XAMPP using gmail… cost 5$ [PayPal] send email to mymac@poliscarhire.com and lsepolis123@gmail.com …

Send email SAMPLE scripts:

<?php

$email = "USERNAME3@gmail.com";

$to = "{$email}";

Arranging Boot Order in BIOS

lse February 20th, 2016

Note Boot Order in my PC: In my PC a HP Compaq 8200 Elite Micro Tower PC , On startup PC Press(press many times the …) just prior Windows 10 logo appear:

F9 – temporary choose Boot Device (Disk) – without changing/entering the BIOS setup

F10 – enter Bios setup to set Boot Order Permanently, till you change it again

===============

Set Boot Order

To arrange boot order in BIOS so can boot from desired location/media/disk you setup Bios temp or permanently so the desired is the first booting device e.g. DVD (1) > USB stick/Disk (2) > HDD (3) … meaning boot from DVD if you have bootable CD or DVD, (if not) boot from USB if you have Bootable USB Stick or USB HDD… etc.

To boot from DVD Or USB bootable media:
1. If you use a USB flash drive as a bootable media, plug it into the USB port.
2. Turn your computer on. During the Power-On Self Test (POST), you will see the key combination that you need to press in order to enter BIOS.
3. Press the key combination (such as, Del, F1, Ctrl+Alt+Esc, Ctrl+Esc, in my PC is F10). BIOS setup utility will open. Note that BIOS may differ in appearance, sets of items, names, etc.
Some motherboards have a so called boot menu opened by pressing a certain key or key combination, for instance, F12. The boot menu allows selecting the boot device from a list of bootable devices without changing the BIOS setup [in my PC this is F9].
4. If you use a CD or DVD as a bootable media, insert it in the CD or DVD drive.
5. Make your media (CD, DVD or USB drive) device the first booting device:

1. Navigate to the Boot order setting by using the arrow keys on your keyboard.
2. Place the pointer on the device of your bootable media and make it the first item in the list. You can usually use the Plus Sign and the Minus Sign keys to change the order.

boot order in Bios

6. Exit BIOS and save the changes that you made. The computer will boot from bootable media if present.
If the computer fails to boot from the first device, it tries to boot from the second device in the list, and so on.

Free Tools for Mac users – most are for Windows/Linux as well

lse April 27th, 2015

File Vault, Time Machine & Cloud Storage etc cool Mac tasks that not cost you a dime
Free Tools for Mac users – most are for Windows/Linux as well

==============================

Note:

This article aimed for Mac users or developers using a Mac, and is about the free tools you can use for development, or the basic Mac computer tasks make you safer or more productive user/developer.
Mac tricks makes you a better User.

File Vault – encrypt your drive

With File Vault (read more below) enabled you can encrypt your Mac SSD or HDD Drive so every time you switch on your Mac you insert a pass phrase to use it. Even your Disk drive removed from your Mac and used elsewhere your data are still Not accessible without the secret pass phrase. Pass phrase can be your Apple ID password in new Macs. You can disable/re-enable it if you like or if you do Not want it any more.

Anti-Virus

As of Anti-virus I use the Free AVG for Mac Anti-Virus [note: Viruses are very rare on Macs].

Time Machine & Cloud Storage – two(2) different backup methods, required both

Time Machine backups – if the File Vault is enabled – require pass phrase so in other words backup is encrypted and protected. Time Machine backup – you can restore even OS, Apps and Data with it – is done by me every 2-3 months since I have and Windows PCs and use Mac 2-4 times a week only. During backup I exclude my Parallels Virtual Machines since do not use a lot and backup separately every year Ubuntu OS, Chrome OS & Windows Vista OS.

I also use for instant backup Cloud Storage from many cloud storage providers (all free plans 5GB-15GB) namely iCloud Drive(Apple), Google Drive, One Drive(Microsoft), Dropbox Drive. If for example I create a mock-up, doc, ppt, xls or other file, I save it to cloud, that way is on my machine and cloud and can also access from other devices including mobile (connected to the cloud/internet). So I feel secure and impossible to loose data and any file… All for free.

Write, Keynote, Numbers, Apple Mail

What I also like about (new) Macs is that come pre-installed with Write, Keynote, Numbers Apps and also Apple Mail.

Mac OS Server App

I also installed Mac OS Server App (by Apple that cost below 20$ – the only expense as of software) that make the Mac a server[web server, mail server, … Etc] and I am experimenting with it…

Web/Mobile Developer/Designer Applications – mostly free and open source

As an web/mobile developer/designer I build mobile apps and responsive sites so, I installed – free mostly given, tools by Mobile OS mfg like Google, Apple & MicroSoft – SDKs for Android and iOS, Xcode, Eclipse, JDeveloper, Android Studio, Intel XDK IDE, Brackets web code editor, NetBeans, Cordova CLI tools, NodeJs, all freeware. Basically I find that I need nothing else for my work except Adobe Fireworks or PhotoShop (paid both) but you can install the freeware GIMPShop that just do the same.
Note: all the tools in this paragraph exist also for Windows(not Xcode/iOS-SDK) and some for Linux.
Addition: I recently installed VMWare Fusion Pro 8 and run Windows 10 Pro VM and added Visual Studio 2015 Community IDE for Windows Development on the Mac.

Conclusion

With these tools you can become an advanced & safer user/developer at almost no cost.

The benefits of education will only be online, nationally and internationally, from digital devices of now and the future

lse March 18th, 2015

The benefits of education will only be online, nationally and internationally,
from digital devices of now and the future

In fact the proliferation of only online education should make public schools and governments more involved in online virtual world and I think should bring many benefits in addition to benefits brought by the involvement of Internet today.

There will be many accurate and free online academic and other resources from government agencies, making the web a better place. This should influence all Internet workforce but mainly online learners, researchers and students. Also government agencies should develop more and better and free online learning tools helping more the online web workers, students and learners to learn what they want easily and accurately.

Also not optional online education will make offline education limited to only practical sessions required in some educational fields. In a few years with this setup, required online education should self-develop to the level could not make any further progress, so the world will reach a peak in technology and education development. This will make the most people to achieve the skills in their target subject or subjects easily.

Online education means learning without distractions, at your comfort or your own environment. You no longer will have to travel to school or buy books or other school materials. In other words costs and time should be saved and used for other activities that bring more skills and learning than it’s offline counterpart.

The technology tools for permanent online education I think should be the same as today’s online education, the Computer, Tablet, and Phone, and the Network, as of hardware. The development of software connected to Internet should make a lot of progress and development with gov agencies involved. Books should be in electronic format in digital libraries either governments’ public online libraries or schools online libraries.

Communication will increase but stay to the level of today with email, and chat text, voice, video, notifications and alerts, and social networks communication. This via Wi-Fi and cellular 3G and 4G technologies.

In conclusion I think governments should enforce required online education, and by the year 2020 all countries’ education should be online. All walks of life will reach top development by then.

Tablets in schools and universities

lse July 12th, 2014

Author: Leonidas Savvides, @lwdlse

Computing in class: Desktop: 1990-2000, Laptop: 2000-2010, Tablet: 2010+
Main Tablet OS: Google Android, Apple iOS, MicroSoft Windows 8/10

Two decades ago and particularly from 1990-2000 desktops were de facto standard for students. A decade ago and particularly from 2000 to 2010, laptops started transforming the college experience; today and from 2010, tablets have become a necessity and a way to reduce costs and to become more efficient in all our productivity and more.

Tablets complement Smart Phones although there are many uses exclusively to each.

As an essential to student success Tablets will become this year (2014-2015) the tool of every student, in other words no student can do without one. These smart screens provide tactile, intuitive experiences that are perfect for hands-on learning and social interaction. Given that books and friends are college students’ primary priorities, the tablet is a great tool for achieving academic and social success.

With so many Apps for Tablets is hard to imagine a task you cannot do without.

Tablets represent efficiency in the classroom. They allow for faster, more fluid learning in both lectures and seminars, as the tablet enables quicker note taking. Easy access to apps in class allows students to engage with new information and contribute relevant material to the class conversation. That means that info is instantly accessible, so that students can instead concentrate on critical thinking.

The physical dimensions and nature of Laptops are done them unsuitable for classroom or at least not like their successors Tablets; this for the face to face professor-student or student-student communication.

Financially, tablets reduce the costs in the long run. They offer additional savings through e-books—a cheaper, lighter alternative to expensive textbooks. Also you have the ability to keep your eBooks intact and annotate digitally a copy of them, and keep them both in Tablet or Computer where easy access and no non-found problems. Also eBooks take no space in your room any number to have.

Personally I believe the more you know about Apps and Tablet usage the more benefit you will have from it. College students should benefit more from High School students and from Primary Pupils. Gaming I think goes more for non-college users.

I think Tablets should be introduced to schools of all levels by law and special education (and guides published) about their usage should be provided appropriately. Also students must be given special treatment not to spent most of their time in non-education matters such watching video or playing games, rather concentrate first on their courses and if there is spare time to do concentrate on some other activity.

The benefits and drawbacks of modern technology

lse September 5th, 2011

When someone refers for today’s modern technology, surely he refers to the 21st century, Information Age and the Internet as the communication media of the new millennium. Of course this 17 year history of the Internet brought indirectly many significant advances in other Science and Technology fields. Without doubt Internet changed our lives for ever decisively and absolutely.

Today, just with a PC and an internet connection, without additional costs you can send instantly and receive instantly messages(emails) from the other corner of the world just not long before ago you have to await letter to get to recipient in about 7 days if not lost in transit and other so the reply to return to you. Now you can find almost any piece of info with a web browser and chat (eg.Skype), again freely using text, audio or even video.

Another area of technology bring change to us, is Mobile Communications. We are NOT away from the fact each individual, will posses a mobile phone for fun or for business, anywhere he is in the world, anytime. Today exists such services in the mobile world as talking, Small Message Service (SMS), Multimedia Message Service (MMS), or chatting with text, and also accessing the Internet from mobile phone using either wifi access point or 3G cellular internet, and hence you may browse or send email or use some other service of the Internet, anywhere and anytime. Coming is Mobile video calling.

Of course Mobile Communications is very closely related to the Internet, both networks belonging to Electronic Age Revolution of computers in general. This top edge of technology brings us many benefits as well as drawbacks too.

Benefits include fast and more accurate communications and business. Now for example in case of danger eg car accident away from the town, you can use your mobile to call the emergency number immediately and authorities to find automatically using cellular network services, your position on the map you call from, so help come accurately and immediately.

Internet makes us more Socialable people in all steps of life, Social Internet Networks are on rise these days. Now our time is better spent, and use efficiently. Rather use snail mail now we are using email, rather use standard telephone network call now we are using chatting via text, audio, video and file transfer. Almost now any info can get accessed via a web browser using an Internet search engine.

Chatting etc services brings fun, work and education too. Leaning online is a consequence of all these. Now universities provide part or full degrees online. This use of internet technology tools and cost is only from university fees. Also language learning can be taken with technology and resources of the Internet. All these are a click away.

As of security now when you are away, you can watch your office or home via security cameras through the internet. Also when you plan a trip domestic or international, on the Internet you can plan and book everything for it. Also, your Bank can accessed via internet banking with a web browser, so as access accounts, transfer money, order replacements etc.

On the other hand beyond these benefits, Internet Age brings and some subtle drawbacks.

Now when you are online your Internet PC without even know it can get compromised by bad guys, that can stole anything from company data to credit card numbers covering their tracks. The attacks can be done on Internet Servers as well, making services unavailable, may be in emergency sometimes. Banks are on instant danger for example, a bad guy may change account data and more.

Of course many anti-criminal tools exist like anti-virus tools, anti-malware, anti-spyware and so on, that must be considered by any Internet user.

Of course as internet makes us smarter, so does smarter the street thieves too. So we must be careful in using all of our possessions, and especially credit cards in front of cameras in all steps of life. Thieves continue to discover new ways, to draw your attention, and so on and so forth.

Finally I think new technology has brought many advantages and drawbacks. People behind the internet and technology think well before they create it, so as to advance our lives and NOT to degrade it. So in my opinion I believe, modern technology has brought more goods to us, rather than drawbacks. In case of drawbacks exist always an anti solution. Technology is going to advance, but as we proceed this is going more slowly, and it will stay good for us, in all its way.

Leaflet: Security of your Possessions while you are traveling

lse September 5th, 2011

When you plan to travel abroad you must take actions, “Before you go” as well as “During your stay” and also “On your return”.

Here are the most important actions you must take care of:

A) Before you go

Money & ID matters

Make two photocopies of your Passport, ID card, Drivers License, Credit Cards, and Airline or Sea Tickets. Also note your Laptop and Mobile phone S/Ns etc id numbers and characteristics so can identified in case found after lost. Keep one copy in your home and the other in your suitcase not near your valuables.

Do NOT take with you, all your credit cards, Social security card but only the necessary ones. Do not keep all cards or valuables in one place but in two places.

Better take with you an old mobile phone or old laptop without important data on them like passwords, you may just want to access with this laptop your bank account over the internet, but only in secure places like your hotel, but not in internet cafes.

After contact your Bank saying you plan to travel in the particular country for any advice tips has and can give. Ask in case of lost or theft of money possessions like cards or cash how to cancel and how to replace them anywhere in the places you plan to travel taking all possibilities. Learn phone numbers or web sites you can disable cards in case of lost or order new ones along with cash. Keep these along photocopies above and on your mobile phone. Also keep emergency numbers in the visited country like Hospital, Police, Fire, Hotel, Taxis, and your embassy of course.

Country profile

First read country profile, and learn about laws & customs, criminality, maps, transport routes, internet criminality, and recent news. All can found online.

General

Also it is good if, in a country where English is spoken in a small scale, to learn some local language words/phrases and bring with you a Language-to-Language Dialogs pocket-book, this could be used anywhere in your trip.

Laptop & Mobile Phone (wifi/3G/Roaming)

Find out on your trip places and stays where could you have safe internet connection (May for internet banking) and also arrange with your cellular and internet provider in your home country, roaming costs and plans for the visited country. You may consider buying a Roaming Data plan for your internet connections, for one month from your cellular provider.

Notify some family members or some friends only of your trip, and say for example if not on the phone every 2-3 days something happened.

B) During your stay

Hotel

While you are going out of your hotel get with you 2 credit cards and some cash only, rest leave the in hotel safe along with all other ID materials. Keep the pre-referred photocopies in your suitcase.

Lock always the hotel room.

Transportation

Take only authorized taxis.

On trains, trams or buses you may drugged and robbed while sleeping. Avoid long waits in terminals; hence pickpockets, thieves, and violent offenders are common in such areas.

Laptop theft is common in Airports.

Laptop & Mobile Phone (wifi/3G/Roaming)

Use wifi or Ethernet internet connection of your Hotel, but not in internet cafes hence they are more secure. Bad guys may compromise your connection at times and steal private info or install malware in your laptop.

Do not attach Devices in your laptop like USB memory sticks.

Do Logon to company network only from company’s laptop.

If you lost your Laptop or/and Mobile Phone immediately report it, to local authorities and to your consulate with your photocopies and ID numbers.

Money Matters

If you lose your wallet (all or part of your possessions) immediately report it, to local authorities and to your consulate along provide your photocopies. Also call your bank’s staff for this purpose, so as to cancel credit cards and send replacements to your hotel or consulate.

Before you depart for your home country

Just when everything went ok and ready for departure, in your hotel, compare/check/count all your possessions and ID Documents with photocopies like credit cards, traveler’s checks left, Passport, Driving License. If something is missing notify Authorities or Bank immediately.

C) On your return

On your return compare/check/count all your possessions and ID Documents with photocopies like credit cards, traveler’s checks left, Passport, Driving License. If something is missing notify Authorities or Bank immediately.

Also just on arrival home and too thereafter 1 or 2 months, check your Bank Accounts and credit cards statements online from your online bank account, for any malware activity. If you detected anything, you should contact your bank immediately to cancel the credit card(s).

Learn A New Language – via Internet

lse January 31st, 2011

Today is the best time for new Language, learners. Of course, I mean today Internet technology. Learning of course, has to make the big effort for it. Of course if you know 2-3 languages to learn another must be easier, also language are categorized by difficulty
http://en.wikibooks.org/wiki/Language_Learning_Difficulty_for_English_Speakers.
I write this as a Russian learner, for my blog. I choose Russian as, the language has/use 20% of Greek and English words (eg robot=робот=ροπότ). Also Russian is an important language for science and technology. According to a recent study, the number of publications in the sciences is highest for English, with Russian second (link).

The major teaching communication (with distance teacher) tool I use is the free Skype Internet messager [www.skype.com], of course you may use similar free chat/messager tools like GoogleTalk, MSN, …etc but you must use identical tool with teacher. With Skype you may have teacher to student or, teacher to students (group talk), free voice/text/video chat or even screen sharing (Skype 5). With Skype you may also send files to your talking partner… Email client programs also are used widely for communication and homework submit.

You can find a teacher easily online using special websites like
http://language-school-teachers.com and http://skype-language.com/. Here you register free as a teacher or as a student saying the languages you speak and the current interested language to learn. Teachers then look for you, or you(as student) may search/browse for teachers by the language they teach, country they are located, and so on. If you want group lessons which I do not like (by one to one talking you gain more and teacher has to do only with you, although cost is bigger in this case, not as in a group which cost is shared) you may find friends locally or classmates or friends online (facebook,…etc) to learn with you.

Surely exist online websites offering ready online classes with students from around the world, not have to setup yourself the environment…
www.mgu-russian.com/programms/online-russian-course/en
www.primelanguageservices.com
(these also offer one to one Lessons).
Of course, exist for other languages identical Sites, just search for “skype online french lessons” or search the language-school-teachers.com or similar site.

Considering the vast number of sites available today, there is more than enough good information to learn/read about grammar, most common words/verbs, starter points in a language,…etc, in text, voice, or video sometimes, and also quizzes, exercises to practice on, all is free. Also you may find online, some complete ebooks in PDF format, I found 7 in “Learn Russian” (in English) but not all in beginning level. Ebooks are paperbacks in electronic format.

As of real paperback books, there are teach yourself materials or teacher assistance materials for any language online, just search your online bookstore or google eg. “teach yourself Russian books”, or “Learn French books”. You may also find story books (eg novels or short stories) in your target language or search for books in a bookstore in that country language is spoken eg in a Russian bookstore if you look for Russian books, where also you may find all kind of books, from science to technical to social science and so on. If you have difficulty with the language you may try Google Translate to translate whole page to eg Russian->English, also if you click a link next page translated automatically. You may also request from a friend or teacher search a book for you or, even send you some books… The latter may be required for your language studies.

Online also you will find free access to online live or on demand, radio or TV station programs, just search eg “Russian online radio stations”, or any other language. Of course, you must pass the beginner level for this. There are also online newspapers and magazines in any field in your target language, just always search eg. “Russian newspapers”. Sometimes preferred find a website with a list of all newspapers by country like
www.world-newspapers.com. Same applies to magazines/journals although they may be listed together along with newspapers sometimes. You may also like this for Russian http://onejournal.ru/.

As you know on the Internet you can find almost anything, so here is some Learn a language Tips guides
www.wikihow.com/Learn-Any-Language
http://how-to-learn-any-language.com (there’s and multi-language forum too here)

At end, if you have questions and need answer but you do not know where get it, you may post your question in a forum of your target language, just search Google “Russian language forum” register/confirm-Your-Email and post it to appropriate category. Just remember choose “email me upon reply” or you may have to return in forum/myPosts to check for a reply manually.

Other Sites:
www.languageguide.org Have categories of similar items/icons with icon and spelling/pronunciation (voice)
http://imtranslator.com Text-to-speech voice in 10 languages, virtual-keyboards in many more languages, dictionaries, spell Checker, and some others
www.forvo.com All the words in the world pronounced
http://translate.google.com/#ru|en| Translation Gadget with pronunciation (voice)
http://russianpodcast.eu

Please visit my blog to read this online, or browse through the listed resources, as I say before for my target language:Russian.
