Must have software on freshly installed windows – Essential Software after fresh Windows install

Install-update-multiple-programs-applications-at-once-using-ninite

If you're into IT industry even if you don't like installing frequently Windows or you're completely Linux / BSD user, you will certainly have a lot of friends which will want help from you to re-install or fix their Windows 7 / 8 / 10 OS. At least this is the case with me every year, I'm kinda of obliged to install fresh windowses on new bought friends or relatives notebooks / desktop PCs.

Of course according to for whom the new Windows OS installed the preferrences of necessery software varies, however more or less there is sort of standard list of Windows Software which is used daily by most of Avarage Computer user, such as:
 

I tend to install on New Windows installs and thus I have more or less systematized the process.

I try to usually stick to free software where possible for each of the above categories as a Free Software enthusiast and luckily nowadays there is a lot of non-priprietary or at least free as in beer software available out there.

For Windows sysadmins or College and other public institutions networks including multiple of Windows Computers which are not inside a domain and also for people in computer repair shops where daily dozens of windows pre-installs or a set of software Automatic updates are  necessery make sure to take a look at Ninite

As official website introduces Ninite:

Ninite – Install and Update All Your Programs at Once

Of course as Ninite is used by organizations as NASA, Harvard Medical School etc. it is likely the tool might reports your installed list of Windows software and various other Win PC statistical data to Ninite developers and most likely NSA, but this probably doesn't much matter as this is probably by the moment you choose to have installed a Windows OS on your PC.

For Windows System Administrators managing small and middle sized network PCs that are not inside a Domain Controller, Ninite could definitely save hours and at cases even days of boring install and maintainance work. HP Enterprise or HP Inc. Employees or ex-employees would definitely love Ninite, because what Ninite does is pretty much like the well known HP Internal Tool PC COE.

Ninite could also prepare an installer containing multiple applications based on the choice on Ninite's website, so that's also a great thing especially if you need to deploy a different type of Users PCs (Scientific / Gamers / Working etc.)

Perhaps there are also other useful things to install on a new fresh Windows installations, if you're using something I'm missing let me know in comments.

Increase tomcat MaxThreads values to resolve Tomcat timeout issues and sort

Increase_Tomcat_MaxThreads_values_to_resolve_Tomcat_timeout-issues-and-sort

Thanks God, we have just completed (6 months) Migration few Tomcat and TomEE application servers for PG / PP and Scorpion instances from old environment to a new one for a customer.

Though the separate instances of the old environment are being migrated, the overall design of the Current Mode of Operations (CMO) as they use to call it in corporate World and the Future Mode of Operations (FMO) has differences.

The each of applications on old environment is configured to run in Tomcat failover cluster (2 tomcats on 2 separate machines with unique IP addresses are running) and Apache Reverse Proxy is being used with BalanceMember apache directive in order to drop requests to Tomcat cluster to Tomcat node1 and node2. On the new environment however by design the Tomcat cluster is removed and the application request has to be served by single Tomcat instance.

The migration completed fine and in the beginning in the first day (day 1) and day 2 since the environment went in Production and went through the so-called "GoLive", as called in Corporate World- which is a meathor for launching the application to be used as a production environment for customer, the customer reported TimeOut issues.

Some of the requests according to their report would took up to 4 minutes to serve, after a bit of investigation we found out, that though the environment was moved to one Tomcat the (number) amount of connections to application of end clients did not change, thus the timeouts were caused by default MaxThreads being reached and, we needed to to obviously raise that number. Here is the old Apache RP config where we had the 2 Tomcats between which the RP was load balancing:
 

BalancerMember ajp://10.10.10.5:11010 route=node1 connectiontimeout=10 ttl=60 retry=60
BalancerMember ajp://10.10.10.5:11010 route=node2 connectiontimeout=10 ttl=60 retry=60

ProxyPass / balancer://pool/ stickysession=JSESSIONID
ProxyPassReverse / balancer://pool/


As we needed a work around, we come to conclusion that we just need to increase Timeout on RP first so on Apache Reverse Proxy we placed following httpd.conf Virtualhost ProxyPass (directive) configs :

 

ProxyPass / ajp://10.10.10.5:11010/ keepalive=On timeout=30 connectiontimeout=30 retry=20
ProxyPassReverse / ajp://10.10.10.5:11010/

ProxyPass / ajp://10.10.10.5:11010/ keepalive=On timeout=30 connectiontimeout=30 retry=20
ProxyPassReverse / ajp://10.10.10.5:11010/


and following Apache Timeout directives options:

 

Timeout 300
KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 15


Even though the developer tried to insist that the problem was in Reverse Proxy timeout config, they were wrong as I checked the RP logs and there was no "maximum connections reached" errors..

As you could guess what left to check was only Tomcat, after quick evaluation of server.xml, it turned out that the MaxThreads directive on old clustered Tomcats was omitted at all, meaning the default MaxThreads Tomcat value of 200 maximum connections were used, however this was not enough as the client was quering the application with about 350 connections / sec.

The solution was of course to raise the Maxthreads to 400 we were pretty lucky that we already had a good dedicated Linux machine where the application was hosted (16GB Ram, 2 CPUs x 2.67 Ghz), thus raising MaxThreads to 400 was not such a big deal.

Here is the final config we used to fix tomcat timeouts:
 

<Connector port="11010" address="10.10.10.80" protocol="AJP/1.3" redirectPort="8443" MaxThreads="400" connectionTimeout="300000" keepAliveTimeout="300000" debug="9" />


One note to make here is the debug="9" options to Connector directive was used to increase debug loglevel of Tomcat, and address="" is the local network IP on which Tomcat instance runs. As you see, we choose to use very high connectionTimeouts (because it is crucial, not to cut requests to applications due to timeouts) in case of application slowness.

We also suspected that there are some Oracle (ORA) database queries slowly served on the SQL backend, that might in future cause more app slowness, but this has to be checked seperately further in time as presently we were checking we did not have our Db person present.

 

12 разбойников / Жило 12 разбойников – Руская православно-народная песен

Monday, November 19th, 2012

12 разбойников / Жило 12 разбойников – Руская православно-народная песен On the Church service in Nijmegen in the Serbian Orthodox Church today, there were Rusian priest guests invited by on e Dutch orthodox person who sings in Russian Orthodox Church choire in Nijmegen. The priest came from saint Peterburg Russia. The serving priest was father Sergii, he came with a deacon. The usual Saint John of Crysostom holy liturgy was served by the Russian priest Father Sergii, who was also with a deacon (I think also from st. Peterburg). The church service as every Church service was a great experience for all orthodox. After the end of service in the traditional way as they do it here, all brothers from the Church had a sort of Agape small meal together. I traveled to Nijmegen with Father Dushan who was kind enough to take me with his car Wolkswagen to the Byzantine Capel Church in Nijmegen. As the serving priest and the deacon was guest priests, father sergii asked them to sing a traditional Russian-Church folklore song called 12 Robbars (Burglars)
I hear the song for a first time, and I found it quite beautiful and decided to reshare for people. It seems 12 Разбойников is a song well known by Russians, but maybe less known among non-Russians. Enjoy 🙂

Иван Ребров – Жило двенадцать разбойников Jilo 12 Razboinikov is a song telling a story about 12 Burglars, who killed a lot of Christian and stole a lot of treasures while stalking in the woods. But a big change happened in them as they repented and become monks and prayed to God asking for forgiveness of their sins and asking for mercy of them and the whole world. Really nice piece of Spiritual Song.

By the way the Spiritual Living of the Parohija (as Serbians call their parish) headed in Nijmegen here by Father Dushan is quite rich. Just two weeks ago there was a great deal happening as two Serbian Church Bishops came for the feast of birth of Saint Constantine and Remembrance of saint Constantine and Helena (which took place in Nish nowdays Serbia (ex-Yugoslavia).

I heard from Father (Hieromonk) Dushan who is serving in the 3 Serbian Orthodox Churches here in Holland (in Breda, Nijmegen and Amsterdam), that next month (December 2012) here in Serbian Orthodox Church Nijmegen a guest priest will come from Syriac orthodox Church (belonging to Antiochian Patriarchy) to serve a Holy Liturgy in Arabic! Will be interesting to see.

How to set applications (programs) Autorun on XFCE in Xubuntu Linux

Monday, January 16th, 2012

I needed to set TeamViewer to autorun, each and every startup on one Xubuntu Linux

Xubuntu is running by default with Xfce 4 . Xfce is a sort of a very liteweight GNOME like graphical environment.

In Gnome the way that is through invoking the gnome-session-manager .

In Xfce the command is almost analogous doing changes is done by running:

user@xubuntu:~$ xfce4-session-manager

XFce session manager Xubuntu Linux screenshot
Further on simply use the Add button to add applications to load each time user (opens xfce session) / logs in.
Cheers 😉

The Tuesday in Holland and a Sunday shock in Protestatant Church

Wednesday, October 29th, 2008

Well I haven’t blog for a while so I decided to give a shot. And Glorify God! Again!At Monday I had my defense of the the Change Management project we handed in inMr. Vinke’s pigeon box. I trusted to God and prayed fervently. The Monday wentjust flawless Glory be to the Holy Trinity (The Father, The Son and the Holy Spirit)! Amen!Everything went quite well during the Management Meeting. Each 3 who constructed my groupwere able to partake at the right moment. I was really calm and peaceful during the whole meeting!Cause of God’s mercy and power who was helping me and helping us. Our teachers who pretended to bea Managers in a company gave their point on our Change Management Plan. They tried to squeezeus with unfortable questions. Happily we had a reasonable answers on most of them. What’s left now is to fix few minor things about the plan and then hand it in to the teachers.Afterwards I hope if everything is ok, each one of 3 of us will receive an individual task andwill start working on it. Am let me recall some memories from the day before. Max (a black guy),who happens to be my neighbor and a Christian also invited me to join his protestant presbetyrianChuch he attend. I accepted since I feel a need to be in the Church and the Orthodox Church missesme so much.. Well we went to a building with a hall in which the protestant Church gathered together.The reason I accepted to join that Church was that they preach in English there.I was quite stunned when I found out that the pastor is actually a female (a black one).They started with a sort of entry speech or at least it looked like this to me.The service continued as the pastor went out preaching. Oh boy, Oh boy what a preach it was,I couldn’t believe on my eyes. The pastor acted completely like a general she was screamingpassages of the Holy Bible, stressing out on some of the things. Blaming the pplthat they fail to understand the Bible she asked them that the ppl ask God for enligthmenton what this passages red. Then the service moved by as a few individuals were invitedto share testimonies of what God has done for them during the week.. A little laterthere was a sort of prayer session where everybody was praying with different prayer,it was like an uncontrolled crowd in which each one of them acted completely different.Some of them were screaming hysterically at moments I was scared to be honest.Then the pastor took the bottle of oil and started laying hands upon some of the pplof the Church, Oh God they were shaking falling down on the ground, screaming makinggrimaces, it was an awful things to see .. I was not aware if the people were pretendingor this is real. The pastor was Chasing away demons out of the ppl, or at leastshe told me later that this is what she does. It was such bad place to be I was eageringto be out of this place as fast as possible as the ppl (Church) acted like a sect.The Pastor wanted to lay hands on me either but I rejected the proposition with the words,”No, No, I’m Orthodox”. Later I tried to explain to some of the ppl my concernsabout what is wrong in this church according to me. And a woman (a real piggy one),started arguing with me with the arguments that I quote her here “i’m God”, was likeshit this guys are even blasphemous. Luckily some of the other members of the Churchcorrected the questionable lady that she is wrong although she was unwilling to acceptthe fact. Later I had a little chat with the pastor and her husband plus onemore lady. Let’s say that their belief was closer to the Faith reality than the rest.But still I was really shocked from the experience … I don’t know if they’re wrong or rightall I know and want is that God have mercy over them and me and guide us to know his truth completely.About today: Well let’s say a peaceful they it was, except the fact that one of the webservershad died. And was not acceptable for around an hour and a half. As soon as a colleagueinformed me I restarted the failed apache. I could say I haven’t done much from middaytill the early afternoon I spend in the University accompanied by Ina. We had fewtalks about stuff and so on and so on. When I came back “home” to the dorm.I worked a bit. I spend some time learning some english words in an effort to enrich my vocabulary.Since there is a Adobe Flash Player 10 for Linux for already a few weeks. I decided to installit on my laptop. Well it took me some time until I installed it correctly. Now I haveAdobe Flash 10 on my Debian machine! It seems this version of Flash includes a possibilityto use cameras with flash. I was curious about how does this new release of flash performscomparing to the old Adobe Flash 9. According to a Benchmarking made on Linux and Macit is said that Flash 10 tend to be less CPU hungry and in general peforms better than it’spredecessor. The whole article could be red on the here . Let me conclude that post with a cool thing. A friend of mine has referred me to the following “Virtual Barbershop” check it out here link . Be sure that you listen it on headphones otherwise you won’t be able to fully enjoy it! :)END—–

Opera!

Saturday, May 10th, 2008

Yesterday I and Alex went to an Opera. We watched Opera by Giuseppe Verdi called “La Traviata”.It’s the second time I see this opera, the first time was when I was still a puppil.Pretty awesome opera the actors were really good. And this classic music! Awesome!After the Opera performance I phoned to Ivo a.k.a. (Order)we went to a sort of pub which wasextremely cheap considering the fact it was near the center and the food and drinks were really good.After all this we had a walk around in Varna and hitted the road back to Dobrich.Kimmo My finish colleague is leaving for Finland and was organizing farewell party.Unfortunately because of the Opera I was unable to go to the party. Yesterday was a really niceday considering that nice opera show. The bad news for me yesterday was that I didn’t passedthe written exam in German and I have to go to the re-sit at Tuesday. With the Lord’s helpI hope I would pass it 🙂 Also I’m going to start for the Accounting exam because It’s at Monday.END—–

My cousin’s Marriage – Impressian from Burgas (Bulgaria) marriage and Kamenartzi herbal healer

Sunday, March 9th, 2008

kamenar-near-burgas-herbal-healing-bai-Dimitar-natural-healear-who-was-healing-cancer
We (Me and My Family) had to stand up early in the morning around 4:30 in Saturday and we traveled to Burgas. First we had to go to a herbman to prescribe me some Herbs. The herbamn is called “bai Dimitar” where bai is a bulgarian specific title for a man on age after the middle age he is located in Kamenartzi village (a small village near Bourgas). He is a sort of strange guy and is speaking very strange things. I hope this herbs will help me. I have to boil them and drink them five times a day. After that we went to Bourgas in my aunt Galia and uncle Galen’s apartment. Everything was a sort was going smooth, Gergana my cousin which was going to merry dressed with a bride dress and waited for his future man (son-in-law). The guy appeared with a limosine and an orchestra. Some ordinary Bulgarian rituals were followed after that the ceremony continued in the council house. Where they became man and wife officially (in front of Bulgaria). After that it followed a celebration in a Bourgas Hotel called “Bulgaria”. The celebration of the marriage included again different traditional Bulgarian dances, guest also danced and ofcourse the Bulgarian familiar horos. I did eat a lot of food and drinked a lot of the meaningless of marriage and all this vanity into celebrity and a lot of empty words spokened there I also convinced myself that I would NEVER EVER allow to have a marriage celebration like this. Some 20 or 30% of the music was Chalga which ofcourse drived me mad. In somewhere 05:00 in the morning we traveled back by car with my father driving. My father is driver from some few months and I definetely can’t say he is an experiencable type of driver which may allow himself to drive with speed higher than the maximum allowed, anywayz he did and I just tried to make him aware that he is braking the driver codex rules. He instead of taking my notes which I made with the idea that I would like to be home back ALIVE, nagged him and he started yelling at me and telling me to stop to complain. That ended in again making me hate him and regret I have parents like this which was a expected to happen since I was angry at all the stupidity and the low intelectual level of most of the ppl who were invited into the Marriage ceremony (although most of them were businessman and a ppl with a high degrees, education). The thing that irritated me the most that the had a marriage ceremony in a orthodox Church and they probably did this just because this is the ordinary way most ppl in Bulgaria does. PFF.. I have slept just for a hour or two today so I probably will go to sleep soon. But first I intend to go for a Liturgy in St. George’s orthodox church. This is after 20 minutes from now. Well thats most of how I spend my saturday on “nothing”. The good thing from all that was that Niki, a.k.a. Nomen’s brother has given me his PSP for the weekend. So I had the time to examine it and generally play with it. I even used a free wifi access in the restaurant where we were and did a bit of browsing :)END—–

Geri’s Birthday

Friday, January 18th, 2008

The day before yesterday, I was in a pretty bad mood and decided to went out. I went to the Mino’s coffee and accidently it happened that Geri a friend of mine had a birthday it was refreshing to spend some timewith real people even thought I thought about all’s behaviour and particularly “how hipocrity they are”.I drinked two glasses of wine for which Miro (Geri’s husband) said it smells like socks. Good heavens my nose was stalled. Yesterday I was out for a coffee with Lily :). 

The weekend was a sort of peaceful.Servers and everything runs fine thanks to the Lord! (ofcourse). I’ll end the post with a quote fromthe bible through the small program called “verse”.

Here is the quote” “For the eyes of the LORD run to and fro throughout the whole earth, to show himself strong in the behalf of them whose heart is perfect toward him…” II Chronicles 16:9 :)END—–

One more day passed

Thursday, November 29th, 2007

One more day passed. I have pains and I scream to God for guidance and help. I’m not sure where am going to as usual. Today we had to have German. I wentto the college only to find out that the German lesson is removed from the schedule. A friend of mine who is in germany Shaltev has sent me a Video of his band.The band is called viamala, here is there website http://viamala.org. I really liked there music btw. Tomorrow I have Dutch. The day was a sort of quite for me thanks and Praise be to the Lord creator. By the way my health is not well. I have pains in different organs sometimes. You know life is hard. I’m loving more and more the FreeBSD :). I watched Ice Age and currently I’m watching Ice Age 2. Great anime (I’m having fun with it. I often think of becoming a monk. Life is such a vanity.END—–
