"Attention required | cloudfare.... one more step," what is it???
In the past few days, when I try to open some pages from google search, it leads me to the correct url but it first shows a page that says ATTENTION REQUIRED | CLOUDFARE
One more Step
Please complete the security check to access www.athriftymrs.com ... which was the website i was trying to visit.
and then it asks me to fill the captcha and something with a yield icon that says what can i do to prevent this in the future and it gives me a tip that I should use a malware scanner.
This is the link i tried to visit http://www.athriftymrs.com/2013/11/how-to-make-your-towels-fluffy-again.html
I never proceeded to enter the captcha but I really want to know what is going on. Because on windows, it supposedly means that you have malware and you should delete or change some host files.... but Im not really sure with the mac os X 10.7.5 tho.
HELP! btw, this happened on a couple of other websites too...
Well! I am not a tech guy. I am just a tech enthusiast and an end user of Apple products. I am a doctor but I do like to play with software, hardware and networking stuff that I get exposed to.
When I replied to for the first time, as above, I'd suggested you guys to use safari extensions to detect whether any website is a problematic one or not. After that (or maybe even before that reply), I personally have encountered cloudflare.com for many times. I think until now, I didn't realize what you guys were actually wanted to ask, in regards to cloudflare.com.
Before today, this thing didn't flash in my mind because of the following 2 reasons.
1. Even though, I've encountered cloudflare.com for at least 20/30 times in the past 2 months, I've never seen it as a problem (as you guys did). The reason behind me encountering that site (asking me to verify if I was human through a captcha) was too obvious to me after my 1st or 2nd encounter with cloudflare. Why? ... I am going to explain that below.
2. The cloudflare.com link that somebody have posted above, leads to the homepage of the cloudflare.com. And it is not the same page that we encounter while going to some other websites, e.g. athriftymrs.com link posted by @mh2khin above.
These 2 mistakes above, kept me away from understanding you guys' real concern.
SOLUTION to your problem (I've discovered this though my own encounters and don't know if this is posted elsewhere).
This website is not a threat to your security. It is not a malicious software or a survey loop or a website that wants to sell you something.
Actually, the website sees you guys as threat to the security and services of its own and its clients. And that's the reason behind cloudflare.com asking you to enter captcha solution to confirm that you are a human and not a bot.
Just google cloudflare.com and you will know what it is and what services it provides.
I really don't know the proper tech terms but, what I've understood by myself from the first/second encounter with the website is that coludflare.com is a web hosting service. It is a cloud based server or something of that sort. So, when you want to visit a website that is hosted on cloudflare.com servers, it is cloudflar.com's responsibility to protect the data and service of cloudflare and its clients. Also, by asking the captcha thingy, cloudflare.com security is trying to avoid automated traffic attack though bots.
Ok, now I understood that the website is just trying to protect itself.
But, BIG QUESTION: WHY ME ? (in you guys' cases ME = you)???
Well, I have a sure-hot answer for "WHY ME" (ME= TimbukTrue)? And most likely, it is also the case when ME= mh2khin or dipakcg, etc.
It is because I was experimenting with VPNs or Proxy server bypasses or a TOR Browser, when I encountered the problem.
As I've tried to explain above, the cloudflare.com is a web hosting service. It is trying to protect itself and its clients.
Even though, VPN / Proxy server / TOR are highly secure services that protect my identity, their exit IPs are limited in numbers. While the number of subscribers they carry could be any number. It is most certain that the IP address that cloudflare.com getting signals from (via VPN/Proxy/TOR) is used by thousands of people around the world everyday. Thus, cloudflare.com's safety mechanism sees it as a threat and wants you to prove yourself as an alive human before letting you in and increasing incoming and outgoing traffic as well as accessing data stored on their servers.
Sorry for this big essay, but, as I've mentioned earlier, I am not a tech guy. So, I couldn't keep it short and sweet.
Anyways.
I can say for sure that cloudflare.com is safe and good website. In my above post, I have mentioned a safari extension named 'WOT' (Web Of Trust). I have attached a picture of WOT rating of cloudflare.com to support my belief that cloudflare.com is safe to visit.
Check the reputation of cloudflare.com at https://www.mywot.com/en/scorecard/cloudflare.com
If you still don't want to see cloudflare.com on your way to your desired website, try to go thru a unique end user IP (e.g. home broadband connection) and not through a professional bypass service (e.g. VPN, Proxy, TOR etc.).
I hope this helps you guys.

Append one more page in old spool number
Hi friend's,
I'm having a script for pick list, now my problem is, if igive the production order for 2nd time, the first spool number has append one more page. what is the solution?
Thanks in Advance.
Vallamuthu.MHi,
I guess your application uses a Smartform or a Sapscript form to create spools.
For sapscripts, when the application call the function module you can useparameters ITCPO-TDNEWID and ITCPO-TDFINAL. For smartforms when you call the function module of the Smartform, you can set 'OUTPUT_OPTIONS-TDDEST' and 'OUTPUT_OPTIONS-TDNEWID'.

I am trying to copy more or less 30G from my MacbookPro to an external hard drive and it is stuck in the "preparing to copy" step. But that for more than one hour. What should I do to make it faster? Thanks a lot in advance!
Thanks Shootist007, by blockd files I mean files that I have changed to blocked and when I tried to move then for the first time, I had to unblock again. I am trying to backup my pictures, my songs and other files like word documents and excel tables. First I put all of them as blocked, what caused the first problems on trying to move them. Then, I've unchecked the block option and if I try to move one by one, there is no problem. The issue is to move all together, because it gets stuck in the preparing to copy files step. Anyway, if I cannot do all by once, I'll do it one by one, event though that was not suposed to happen if we are talking about technology, right? Anyway, I thank you again for trying to help me!

I tried following the steps in this article. When I attempt to delete iTunes, it says “iTunes” can’t be modified or deleted because it’s required by Mac OS X. What other steps could I take to get my MacBook Air to recognize my iphone again? Neither iTunes nor iPhoto recognize my phone any longer.
iTunes can't be deleted because it comes with OS X. In order to delete it, open Terminal and copy:
sudo rm /Applications/iTunes.app
This will remove iTunes, so then you can reinstall iTunes -

One more person who can't send mail but can receive
I sent mail last night and woke up this morning not being able to send mail.
I can receive, but can't send. I can send to my self, but can't reply to others or create new.
The email time out message say's the authentication is on. How that changed over night? Not sure.
Under Mail preferences, Account information, outgoing server settings-
I've been using 2525 with no authentication for over a year. I noticed someone suggesting 465 and 587... didn't work.
I went into advanced and saw where it IS asking for authentication (using password) but in the drop down list it doesn't give the word 'none' just like the account option had to select.
I used the connection Doctor and I have connection...
what else can I do?
Thank you for the help
ChelleThe standard TCP-port for SMTP is 25. If this doesn't work, try to authenticate to the SMTP-server with the credentials of your POP3-login. Maybe your ISP reconfigured his SMTP-servers to use aSMTP.
Some other ISP use a method called "SMTP-after-POP3". This means, that you must fetch your mail using POP3 first. After doing this, you have a specific period of time (at most ISPs 5 to 15 minutes) to send mail from the same IP-address as you have POPed before. This is for additional security.
One more reason could be that your configured SMTP-server is simply "dead" or offline for system maintenance. To check if the machine is alive, go to terminal and
ping nameofyourserver
and see if it responds. If so, try connecting on the SMTP port by typing
telnet nameofyourserver 25
These steps can provide additional information to find the cause for your problem. -
Count of windows in Safari returns one more than actual
First of all I'm completely new to Applescript.
What I do at the moment is to search for scripts that might do something similar to want I want and then modify them to suit my particular requirements.
I have been trying to use a script that searches for a particular URL in Safari.
Here is an excerpt from the script:-
tell application "System Events"
tell application "Safari"
set windowCount to count of windows
repeat ...
end tell
end tell
The problem is that the value returned by "set windowCount to count of windows" returns a value which is one more than the actual number of Windows that are open.
Can anyone tell me why it is going wrong?
Many Thanks
I'm using Script Editor 2.7(176), AppleScript 2.4 on a late 2008 MacBook running Yosemite 10.10.2 and Safari Version 8.0.3 (10600.3.18)Hi,
Try this (don't use this script in the 'tell application "System Events"' block) :
set tUrls to {}
tell application "Safari"
repeat with thisWind in (get windows whose its document is not missing value)

set t to URL of thisTab
if t contains "search string" then set end of tUrls to t

One more dumbshit generics question...
Is there a way to do this without the warnings or the @SuppressWarnings({"unchecked"})
* Returns the index of the last occurrence of the specified element in this
* list, or -1 if this list does not contain the element.
//@SuppressWarnings({"unchecked"})
public int lastIndexOf(Object object) {
int i = 0;
int last = -1;
for(Node<E> node=this.head.next; node!=null; node=node.next) {
if (node.item.equals((E) object)) {
last = i;
i++;
return(last);
produces the warning
C:\Java\home\src\linkedlist\LinkedList.java:313: warning: [unchecked] unchecked cast
found : java.lang.Object
required: E
if (node.item.equals((E) object)) {
^... remembering that List specifies +public int lastIndexOf(Object object);+ as taking a raw Object, not E element, as I would have expected.
Thanx all. Keith.
PS: Crossposted from the tail of http://forum.java.sun.com/thread.jspa?messageID=10225418�
which nobody has answered, I presume because the thread is marked as "answered".I'm not sure you understood or if I made myself clear. Or perhaps I'm missing a vital detail in your implementation.
I'm talking about the cast to E in this line:if (node.item.equals((E) object)) {Object.equals() takes a parameter of type Object. So the cast to E is superfluous. That cast is what's causing the warning. You remove the cast => no more warning => you can remove the SuppressWarnings annotation.
Unless your E's have an overloaded equals() that takes an argument of type E. In that case you'll have to live with it.
