• Security Alert For CVE-2010-4476 Released

  - by eric.maurice

  Hello, this is Eric Maurice again. Oracle just released a Security Alert with a fix for the vulnerability CVE-2010-4476, which affects Oracle Java SE and Oracle Java For Business. This vulnerability is present in Java running on servers as well as standalone Java desktop applications. Its successful exploitation by a malicious attacker can result in a complete denial of service for the affected servers. While only recently publicly disclosed, a number of Internet sites have since then reproduced details about this vulnerability, including exploit codes, which may result in allowing a malicious attacker to create a denial of service condition against the targeted system. Oracle therefore strongly recommends that affected organizations apply this fix as soon as possible. Please note that a fix for this vulnerability will also be included in the upcoming Java Critical Patch Update (Java SE and Java for Business Critical Patch Update - February 2011), which will be released on February 15th 2011. Note that the impact of this vulnerability on desktops is minimal: the affected applications or applets running in Internet browsers for example, might stop responding and may need to be restarted; however the desktop itself will not be compromised (i.e. no compromise at the desktop OS level). Oracle therefore recommends that consumers use the Java auto-update mechanism to get this fix. This will prompt them to install the latest version of the Java Runtime Environment 6 update 24 or higher (JRE), which includes the fix for this vulnerability. JRE 6 update 24 will also be distributed with the Java SE and Java for Business Critical Patch Update - February 2011. For More Information: The Critical Patch Updates and Security Alerts page is located at http://www.oracle.com/technetwork/topics/security/alerts-086861.html The Advisory for Security Alert CVE-2010-4476 is located at http://www.oracle.com/technetwork/topics/security/alert-cve-2010-4476-305811.html More information on Oracle Software Security Assurance is located at http://www.oracle.com/us/support/assurance/index.html Consumers can go to http://www.java.com/en/download/installed.jsp to ensure that they have the latest version of Java running on their desktops. More information on Java Update is available at http://www.java.com/en/download/help/java_update.xml

• Security Alert for CVE-2010-0886 and CVE-2010-0887 Released

  - by eric.maurice

  Hi, this is Eric Maurice again! Oracle just released a Security Alert to announce the availability of fixes for two vulnerabilities (CVE-2010-0886 and CVE-2010-0887) affecting Oracle Java SE and Oracle Java For Business. Both vulnerabilities only affect Java when running in a 32-bit web browser. These vulnerabilities are not present in Java running on servers or standalone Java desktop applications and do not impact any Oracle server based software. The first vulnerability (CVE-2010-0886) affects the Java Deployment Toolkit (version 6 update 10 through 19) on Windows only. The second vulnerability (CVE-2010-0887) affects the Java Plug-in (version 6 update 18 and 19) on Windows, Solaris and Linux. Both vulnerabilities may allow an attacker to run commands on the user's system with the privileges of the user, whose system may have become compromised by visiting a malicious web site. Oracle rated the severity of both vulnerabilities with a CVSS Base Score of 10.0 because many Windows users grant themselves administrative privileges. However, on other platforms, or for Windows users with limited privileges, the CVSS Base Score is only 7.5, because a successful exploitation of these vulnerabilities cannot result in a full compromise of the affected system. Users can quickly determine if they are running vulnerable versions of Java by pointing their browser to http://www.java.com/en/download/help/testvm.xml. Java SE users can visit http://www.java.com and download the most recent release of Java SE to address these vulnerabilities. Because of the criticality of these vulnerabilities, and the publicity they received as a result of their disclosure before the availability of a fix, Oracle recommends that all customers and Java users update their Java installation to the most recent version (6 update 20). For More Information: The advisory for the Security Alert for CVE-2010-0886 and CVE-2010-0887 is located at http://www.oracle.com/technology/deploy/security/alerts/alert-cve-2010-0886.html

• June 2012 Critical Patch Update for Java SE Released

  - by Eric P. Maurice

  Hi, this is Eric Maurice. Oracle just released the June 2012 Critical Patch Update for Java SE.  This Critical Patch Update provides 14 new security fixes across Java SE products.  As discussed in previous blog entries, Critical Patch Updates for Java SE will, for the foreseeable future, continue to be released on a separate schedule than that of other Oracle products due to previous commitments made to Java customers.  12 of the 14 Java SE vulnerabilities fixed in this Critical Patch Update may be remotely exploitable without authentication.  6 of these vulnerabilities have a CVSS Base Score of 10.0.  In accordance with Oracle’s policies, these CVSS 10 scores represent instances where a user running a Java applet or Java Web Start application has administrator privileges (as is typical on Windows XP).  When the user does not run with administrator privileges (typical on the Solaris and Linux operating systems), the corresponding CVSS impact scores for Confidentiality, Integrity, and Availability for these vulnerabilities would be "Partial" instead of "Complete", thus lowering these CVSS Base Scores to 7.5. Due to the high severity of these vulnerabilities, Oracle recommends that customers obtain and apply these security fixes as soon as possible: Developers should download the latest release at http://www.oracle.com/technetwork/java/javase/downloads/index.html    Java users should download the latest release of JRE at http://java.com, and of course  Windows users can take advantage of the Java Automatic Update to get the latest release. In addition, Oracle recommends removing old an unused versions  of Java as the latest version is always the recommended version as it contains the most recent enhancements, and bug and security fixes.  For more information: •Instructions on removing older (and less secure) versions of Java can be found at http://java.com/en/download/faq/remove_olderversions.xml  •Users can verify that they’re running the most recent version of Java by visiting: http://java.com/en/download/installed.jsp   •The Advisory for the June 2012 Critical Patch Update for Java SE is located at http://www.oracle.com/technetwork/topics/security/javacpujun2012-1515912.html

• April 2010 Critical Patch Update Released

  - by eric.maurice

  Hi, this is Eric Maurice. Today Oracle released the April 2010 Critical Patch Update (CPUApr2010),the first one to include security fixes for Oracle Solaris. Today's Critical Patch Update (CPU) provides 47 new security fixes across the following product families: Oracle Database Server, Oracle Fusion Middleware, Oracle Collaboration Suite, Oracle E-Business Suite, Oracle PeopleSoft Enterprise, Oracle Life Sciences, Retail, and Communications Industry Suites, and Oracle Solaris. 28 of these 47 new vulnerabilities are remotely exploitable without authentication, but the criticality of the affected components and the severity of these vulnerabilities vary greatly. Customers should, as usual, refer to the Risk Matrices in the CPU Advisory to assess the relevance of these fixes for their environment (and the urgency with which to apply the fixes). 7 of the 47 new vulnerabilities affect various versions of Oracle Database Server. None of these 7 vulnerabilities are remotely exploitable without authentication. Furthermore, none of these fixes are applicable to client-only deployments. The most severe CVSS Base Score for the Database Server vulnerabilities is 7.1. As a reminder, information about Oracle's use of the CVSS 2.0 standard can be found in Note 394487.1 (My Oracle Support subscription required). Note that this Critical Patch Update includes fixes for vulnerabilities that were publicly disclosed by David Litchfield at the BlackHat DC Conference in early February (CVE-2010-0866 and CVE-2010-0867). 5 of the 47 new vulnerabilities affect various components of the Oracle Fusion Middleware product family. The highest CVSS Base Score for these vulnerabilities is 7.5. Note that the patches for Oracle WebLogic Server are cumulative and this Critical Patch Update therefore also includes a fix for a vulnerability (CVE-2010-0073) that was the subject of a Security Alert issued by Oracle on February 4, 2010. Customers, who have not applied the previously-released patch, should apply today's Critical Patch Update as soon as possible. As stated at the beginning of this blog, it is also noteworthy to highlight that this Critical Patch Update provides 16 new fixes for the Sun product line. With the recent close of the Sun acquisition both security organizations have worked diligently to align Sun's previous security practices with Oracle's. Java users know that Oracle released a Critical Patch Update for Java SE and Java For Business earlier this month (in accordance with the Java patching schedule previously published by Sun Microsystems). Please note that for the first time, the Java advisories included CVSS Scores to help assess the severity of the new vulnerabilities fixed with the advisory. The rapid inclusion of the Solaris product lines in the Critical Patch Update and the extension of Oracle Software Security Assurance to Sun technologies are evidence of the flexibility of Oracle's security assurance programs. These should also result in tangible security benefits for the users of the Oracle hardware and software stack (such as a predictable patching schedule for all Oracle products).

• February 2011 Java SE and Java for Business Critical Patch Update Released

  - by eric.maurice

  Hello, this is Eric Maurice again. Oracle released the February 2011 Critical Patch Update for Java SE and Java for Business today. As discussed in a previous blog entry, Oracle currently maintains a separate Critical Patch Update schedule for Java SE and Java for Business because of commitments made prior to the Oracle acquisition in regards to the timing for the publication of Java fixes. Today's Java Critical Patch Update includes fixes for 21 vulnerabilities. The most severe CVSS Base Score for vulnerabilities fixed in this CPU is 10.0, and this Base Score affects 8 vulnerabilities. Out of these 21 vulnerabilities, 13 affect Java client deployments. 12 of these 13 vulnerabilities can be exploited through Untrusted Java Web Start applications and Untrusted Java Applets, which run in the Java sandbox with limited privileges. One of these 13 vulnerabilities can be exploited by running a standalone application. In addition, one of the client vulnerability affects Java Update, a Windows-specific component. 3 of the 21 vulnerabilities affect client and server deployments. These vulnerabilities can be exploited through Untrusted Java Web Start applications and Untrusted Java Applets, as well as be exploited by supplying malicious data to APIs in the specified components, such as, for example, through a web service. 3 vulnerabilities affect Java server deployments only. These vulnerabilities can be exploited by supplying malicious data to APIs in the specified Java components. Note that one of these vulnerabilities (CVE-2010-4476) was the subject of a Security Alert released on February 8th. Finally, one of these vulnerabilities is specific to Java DB, a component in the Java JDK, but not included in the Java Runtime Environment (JRE). As usual, because of the severity of the vulnerabilities fixed in this Critical Patch Update, Oracle recommends that Java customers apply it as soon as possible. The Critical Patch Advisory provides more details about the vulnerabilities addressed in the Critical Patch Update as well as instructions on how to install the fixes and where to get them. Home users should use the Java auto-update mechanism to install the latest version of the Java Runtime Environment 6 update 24 or higher (JRE), which includes the fix for this vulnerability. For More Information: The Critical Patch Updates and Security Alerts page is located at http://www.oracle.com/technetwork/topics/security/alerts-086861.html More information on Oracle Software Security Assurance is located at http://www.oracle.com/us/support/assurance/index.html Consumers can go to http://www.java.com/en/download/installed.jsp to ensure that they have the latest version of Java running on their desktops.

• Security Alert for CVE-2012-4681 Released

  - by Eric P. Maurice

  Hi, this is Eric Maurice again! Oracle has just released Security Alert CVE-2012-4681 to address 3 distinct but related vulnerabilities and one security-in-depth issue affecting Java running in desktop browsers.  These vulnerabilities are: CVE-2012-4681, CVE-2012-1682, CVE-2012-3136, and CVE-2012-0547.  These vulnerabilities are not applicable to standalone Java desktop applications or Java running on servers, i.e. these vulnerabilities do not affect any Oracle server based software. Vulnerabilities CVE-2012-4681, CVE-2012-1682, and CVE-2012-3136 have each received a CVSS Base Score of 10.0.  This score assumes that the affected users have administrative privileges, as is typical in Windows XP.  Vulnerability CVE-20120-0547 has received a CVSS Base Score of 0.0 because this vulnerability is not directly exploitable in typical user deployments, but Oracle has issued a security-in-depth fix for this issue as it can be used in conjunction with other vulnerabilities to significantly increase the overall impact of a successful exploit. If successfully exploited, these vulnerabilities can provide a malicious attacker the ability to plant discretionary binaries onto the compromised system, e.g. the vulnerabilities can be exploited to install malware, including Trojans, onto the targeted system.  Note that this malware may in some instances be detected by current antivirus signatures upon its installation.  Due to the high severity of these vulnerabilities, Oracle recommends that customers apply this Security Alert as soon as possible.  Furthermore, note that the technical details of these vulnerabilities are widely available on the Internet and Oracle has received external reports that these vulnerabilities are being actively exploited in the wild.    Developers should download the latest release at http://www.oracle.com/technetwork/java/javase/downloads/index.html   Java users should download the latest release of JRE at http://java.com, and of course   Windows users can take advantage of the Java Automatic Update to get the latest release. For more information: The Advisory for Security Alert CVE-2012-4681 is located at http://www.oracle.com/technetwork/topics/security/alert-cve-2012-4681-1835715.html  Users can verify that they’re running the most recent version of Java by visiting: http://java.com/en/download/installed.jsp    Instructions on removing older (and less secure) versions of Java can be found at http://java.com/en/download/faq/remove_olderversions.xml

• Haskell web frameworks survey

  - by Phuc Nguyen

  There are several web frameworks for Haskell like Happstack, Snap, and Yesod, and probably a few more. In what aspects do they differ from each other? For example: features (e.g. server only, or also client scripting, easy support for different kinds of database) maturity (e.g. stability, documentation quality) scalability (e.g. performance, handy abstraction) main targets Also, what are examples of real-world sites / web apps using these frameworks? Many thanks.

• Ur/Web new purely functional language for web programming?

  - by Phuc Nguyen

  I came across the Ur/Web project during my search for web frameworks for Haskell-like languages. It looks like a very interesting project done by one person. Basically, it is a domain-specific purely functional language for web programming, taking the best of ML and Haskell. The syntax is ML, but there are type classes and monad from Haskell, and it's strictly evaluated. Server-side is compiled to native code, client to Javascript. See the slides and FAQ page for other advertised advantages. Looking at the demos and their source code, I think the project is very promising. The latest version is something 20110123, so it seems to be under active development at this time. My question: Has anybody here had any further experience with it? Are there problems/annoyances compared to Haskell, apart from ML's slightly more verbose syntax? Even if it's not well known yet, I hope more people will know of it. OMG this looks very cool to me. I don't want this project to die!!

• Avoid SEO loss after URL structure change

  - by Eric Nguyen

  We recently re-wrote our site from Umbraco to WordPress. This has been done by third-party developers. I have been the project manager and it is my mistake that I haven't notice the change of URLs that affect SEO until now. New site was launch last Thursday. The old URL for a "place" (a WordPress custom post type, in case you're WordPress expert and want/ need to point me to another discussion on WP Stackexchange) page is as follows: ourdomain.com/singapore/central/alexandra/an-interesting-place Now it has been changed to ourdomain.com/places/an-interesting-place I have already requested the third-party developers to work rewriting the URLs to emulate the old URL structure. However, it's taking quite a lot of time (we have multiple custom post types e.g. events etc. so it might be complicated; the developers seem quite by blur when I first mentioned rewriting URLs for the custom post types) In the meantime, I wonder if there is a quicker work around for this 1) Use .htaccess to rewrite ourdomain.com/singapore/central/alexandra/an-interesting-place to ourdomain.com/places/an-interesting-place This should avoid 90% loss of the search traffic. I suppose I can learn how to do this quite quickly but no harm mentioning it here 2) Use rel="canonical" to indicate that ourdomain.com/places/an-interesting-place is the exact duplicate of ourdomain.com/singapore/central/alexandra/an-interesting-place I will definitely go for both approaches (and also I'm changing 404 page to cater for this temporary isue) but I wonder if 2) is even feasible and if I have missed anything. Is there anything else you could recommend me in this situation. Let me know if my question is not clear anywhere. Clarifications The old website is on a Windows Server EC2 completely separated from the Linux EC2 instance on which the new site is running. In addition, the same domain "ourdomain.com" is used here (an A record is used to point to an EC2 Elastic IP). Therefore, the old server is completely inaccessible at the moment, unless you we use the IP address to old server (which doesn't help me at all in this case). Even if the old server is accessible, I can't see where one can put the .htaccess or a HTML file to do 301 redirect here. Unless I'm successful with my approach 1) or the developers can rewrite the URLs with coding, 404 page is really a choice for me.

• How To Build An Enterprise Application - Introduction

  - by Tuan Nguyen

  An enterprise application is a software which fulfills 4 core quality attributes: Reliability Flexibility Reusability Maintainability Reliability is the ability of a system or component to perform its required functions under stated conditions for a specific period of time. Because there are no ways more than testing to make sure a system is reliability, we can exchange the term reliability with the term testability. Flexibility is the ability of changing a system's core features without violating unrelated features or components. Although flexibility can helps us to achieve interoperability easily but the opposite is not true. For example, a program might run on multiple platforms, contains logic for many scenarios but that wouldn't mean it was flexibility if it forces us rewrite code in all components when we just want to change some aspects of a feature it had. Reusability is the ability of sharing one or more system's components for another system. We should just open a component's reusability in the context in which it is used. For example, we write classes that implement UI logic and deliver them to only classes which implementing UI. Maintainability is the ability of adding or removing features to a system after it was released. Maintainability consists of many factors such as readability, analyzability, extensibility therein extensibility is critical. Maintainability requires us to write code that is longer and complexer than normal but it doesn't mean we introduce unneccessarily complex code. We always try to make our code clear and transparent to everyone. An application enterprise is built on an enterprise design which consists of two parts: low-level design and high-level design. At low-level design, it focuses on building loose-coupled classes or components. Particularly, it recommends: Each class or component undertakes only single responsibility (design based on unit test) Classes or components implement and work through interfaces (design based on contract) Dependency relationship between classes and components could be injected at run-time (design based on dependency) At high-level design, it focuses on architecting system into tiers and layers. Particularly, it recommends: Divide system into subsystems for deployment. Each subsytem is called a tier. Typical, an enterprise application would have 3 tiers as illustrated in the following figure: Arrange classes and components to logical containers called layers. Typical, an enterprise application would have 5 layers as illustrated in the following figure

• Transfer .com domain to GoDaddy - websites running on same domain - 3 weeks left until expiration, 2 days left web hosting

  - by Eric Nguyen

  Our company purchased this abc.com domain from a local registrar. The domain will expire in about 3 weeks. We have our main websites running on this abc.com domain and they cannot be down for too long. The web hosting service will end in 2 days. Our websites are already hosted and they are up and running on Amazon EC2. We would like to transfer the domain to GoDaddy now or as soon as possible. (since we have many other domains there and we belive GoDaddy will be better in long-term considering the prices and the features it offers) There are many questions on the decision to transfer the domain to GoDaddy: 1) Cost and time required to move out of our local registrar? This is currently unknown as I'm still trying to retrieve the agreement we have with them 2) How does the 3 week time left until expiration of the domain matters here? Should we wait until the domain expires and then purchase in through GoDaddy? How long would such process take as I suppose our websites will be down during that time? Any other drawbacks? 3) What can I do to ensure our websites will continue functioning regardless of the domain transfer process? It seems the actual registrar here is enom.com and the local registrar here just partners with it I suppose I should then park the abc.com domain with enom.com and make changes to DNS settings so that our websites can continue to be hosted on EC2 as normal. How long does it normally take the domain to be transferred to GoDaddy completely? Is it even possible at all to keep our websites are up and running during the whole domain transfer process? Apologies that I'm throwing many questions at the same time here. It's rather last minutes and I suddenly realised there are too many unknown risks.

• Economical DNS hosting separate from local registrar for country specific TLDs - email or web hosting not required

  - by Eric Nguyen

  Our company owns many country specific top level domains (TLDs; .sg, .my). We will purchase more for other countries in all South East Asia. These domains are associated with our websites hosted on Amazon EC2. The DNS records are currently hosted on a dedicated server that will shut down tomorrow. (The name servers are set to the ones of a web hosting company) Therefore, I will need to host the DNS records somewhere else. Hosting the DNS records with the local registrar costs SGD18 a year per domain in addition to the domain price (which is already very expensive but we have no choice). It would be convenience to host DNS recors for all the country specific TLDs we have using a single service, separate from the local registrars from which we bought the domains. A few searches prompted examples like Amazon Route 53 and dnsmadeeasy.com and the likes. However, since I'm only concern about the country specific TLDs, not .com 1) Is it really economical to host DNS records of all domains in 1 single place as described above? (Have the relevant countries and/or the local registrars done something to keep their monopoly and always charges ridiculous prices for their country specific TLDs?) 2) I would imagine I will need to tell the local registrars to update the name servers to those of the DNS hosting service provider e.g. dnsmadeeasy.com here. Am I correct about how it works here? 3) Will I be able point the TLDs themselves to IP addresses I desire (the EC2 instances where my websites are) or will I only able to do so with the subdomains? 4) Are there any drawbacks that I should know here? Background about our needs: We need the websites associated with the country TLDs to be up and running all the times Also, we'll need to be able to add/edit A and CNAME records We use Google Apps for Business for internal email so I will need to be able to add/edit MX records and TXT records

I also have Windows XP running on the machine. Best. @Eric, if you are online, I could use your help (or anybody's else). I installed the package for non-pae unit and I still get the same error. Any suggestions? Thanks

• Okular can't read pdf files

  - by hoang anh Nguyen

  I recently have installed Okular on my Ubuntu 14.04. The problem is when I open pdf files, okular gives me the error "Can not find a plugin which is able to handle the document being passed." When I ran Okular by Terminal, this is the message I get. okular(14100)/kdeui (KIconLoader): Error: standard icon theme "oxygen" not found! okular(14100)/kdeui (KIconLoader): Error: standard icon theme "oxygen" not found! okular(14100) KPixmapSequence::Private::loadSequence: Invalid pixmap specified. okular(14100) KPixmapSequence::Private::loadSequence: Invalid pixmap specified. okular(14100) KPixmapSequence::frameSize: No frame loaded okular(14100) KPixmapSequence::Private::loadSequence: Invalid pixmap specified. okular(14100) KPixmapSequence::frameSize: No frame loaded okular(14100) KPixmapSequence::Private::loadSequence: Invalid pixmap specified. okular(14100) KPixmapSequence::frameSize: No frame loaded okular(14100) KPixmapSequence::Private::loadSequence: Invalid pixmap specified. okular(14100) KPixmapSequence::frameSize: No frame loaded okular(14100) KPixmapSequence::Private::loadSequence: Invalid pixmap specified. okular(14100) KPixmapSequence::frameSize: No frame loaded okular(14100) KPixmapSequence::Private::loadSequence: Invalid pixmap specified. okular(14100) KPixmapSequence::frameSize: No frame loaded okular(14100): No ksycoca4 database available! okular(14100)/kdecore (trader) KServiceTypeTrader::defaultOffers: KServiceTypeTrader: serviceType "okular/Generator" not found okular(14100)/kdecore (KConfigSkeleton) KCoreConfigSkeleton::writeConfig: okular(14100)/kdecore (KConfigSkeleton) KCoreConfigSkeleton::writeConfig: okular(14100)/kdecore (KConfigSkeleton) KCoreConfigSkeleton::writeConfig: okular(14100)/kdecore (KConfigSkeleton) KCoreConfigSkeleton::writeConfig: okular(14100)/kdecore (KConfigSkeleton) KCoreConfigSkeleton::writeConfig: okular(14100): No ksycoca4 database available! okular(14100)/kdecore (trader) mimeTypeSycocaServiceOffers: KMimeTypeTrader: mimeType "application/pdf" not found okular(14100): No ksycoca4 database available! okular(14100)/kdecore (trader): KMimeTypeTrader: couldn't find service type "okular/Generator" Please ensure that the .desktop file for it is installed; then run kbuildsycoca4. okular(14100)/okular (app) Okular::Document::openDocument: No plugin for mimetype '"application/pdf"'. okular(14100): Couldn't start knotify from knotify4.desktop: "KLauncher could not be reached via D-Bus.

• URL masking with .htaccess

  - by Michael Nguyen

  I need a hardcore programmer to help me with URL masking. So this is my situation. My website www.michaelfotograf.dk/blog/ is the main site that needs to be configured. I have another website/webhotel called www.umagepar.dk www.umagepar.dk is redirected to www.michaelfotograf.dk/blog/ The blog is an ongoing project where i post a lot of stuff to get my ranking higher on google. www.umagepar.dk which redirect to www.michaelfotograf.dk/blog/ is also a project on is own, so I do not want people to know, that it is a blog connected with www.michaelfotograf.dk/blog/ I therefore need to mask www.michaelfotograf.dk/blog/ so it will be called www.umagepar.dk in the URL in the searchbar at all times! What I need is a programmer that can do this for me. Name your price, and I'll see if I can affort it. Michael

• Is there a more intelligent way to do this besides a long chain of if statements or switch?

  - by Harrison Nguyen

  I'm implementing an IRC bot that receives a message and I'm checking that message to determine which functions to call. Is there a more clever way of doing this? It seems like it'd quickly get out of hand after I got up to like 20 commands. Perhaps there's a better way to abstract this? public void onMessage(String channel, String sender, String login, String hostname, String message){ if (message.equalsIgnoreCase(".np")){ // TODO: Use Last.fm API to find the now playing } else if (message.toLowerCase().startsWith(".register")) { cmd.registerLastNick(channel, sender, message); } else if (message.toLowerCase().startsWith("give us a countdown")) { cmd.countdown(channel, message); } else if (message.toLowerCase().startsWith("remember am routine")) { cmd.updateAmRoutine(channel, message, sender); } }
