  • How I Work: Staying Productive Whilst Traveling

    - by BuckWoody
    I travel a lot. Not like some folks that are gone every week, mind you, although in the last month I’ve been to: Cambridge, UK; Anchorage, AK; San Jose, CA; Copenhagen, DK, Boston, MA; and I’m currently en-route to Anaheim, CA.  While this many places in a month is a bit unusual for me, I would say I travel frequently. I’ve travelled most of my 28+ years in IT, and at one time was a consultant traveling weekly.   With that much time away from my primary work location, I have to find ways to stay productive. Some might say “just rest – take a nap!” – but I’m not able to do that. For one thing, I’m a very light sleeper and I’ve never slept on a plane - even a 30+ hour trip to New Zealand in Business Class - so that just isn’t option. I also am not always in the plane, of course. There’s the hotel, the taxi/bus/train, the airport and then all that over again when I arrive. Since my regular jobs have many demands, I have to get work done.   Note: No, I’m not always focused on work. I need downtime just like everyone else. Sometimes I just think, watch a movie or listen to tunes – and I give myself permission to do that anytime – sometimes the whole trip. I have too fewheartbeats left in life to only focus on work – it’s just not that important, and neither am I. Some of these tasks are letters to friends and family, or other personal things. What I’m talking about here is a plan, not some task list I have to follow. When I get to the location I’m traveling to, I always build in as much time as I can to ensure I enjoy those sights and the people I’m with. I would find traveling to be a waste if not for that.   The Unrealistic Expectation As I would evaluate the trip I was taking – say a 6-8 hour flight – I would expect to get 10-12 hours of work done. After all, there’s the time at the airport, the taxi and so on, and then of course the time in the air with all of the room, power, internet and everything else I needed to get my work done. I would pile up tasks at home, pack my bags, and head happily to the magical land of the TSA.   Right. On return from the trip, I had accomplished little, had more e-mails and other work that had piled up, and I was tired, hungry, and unorganized. This had to change. So, I decided to do three things: Segment my work Set realistic expectations Plan accordingly  Segmenting By Available Resources The first task was to decide what kind of work I could do in each location – if any. I found that I was dependent on a few things to get work done, such as power, the Internet, and a place to sit down. Before I fly, I take some time at home to get all of the work I’d like to accomplish while away segmented into these areas, and print that out on paper, which goes in my suit-coat pocket along with a mechanical pencil. I print my tickets, and I’m all set for the adventure ahead. Then I simply do each kind of work whenever I’m in that situation. No power There are certain times when I don’t have power available. But not only that, I might not even be able to use most of my electronics. So I now schedule as many phone calls as I can for the taxi/bus/train ride and the airports as I can. I have a paper notebook (Moleskine, of course) and a pencil and I print out any notes or numbers I need prior to the trip. Once I’m airborne or at the airport, I work on my laptop. I check and respond to e-mails, create slides, write code, do architecture, whatever I can.  If I can’t use any electronics, or once the power runs out, I schedule time for reading. I can read at the airport or anywhere, actually, even in-flight or any other transport. I “read with a pencil”, meaning I take a lot of notes, which I liketo put in OneNote, but since in most cases I don’t have power, I use the Moleskine to do that. Speaking of which, sometimes as I’m thinking I come up with new topics, ideas, blog posts, or things to teach in my classes. Once again I take out the notebook and write it down. All of these notes get a check-mark when I get back to the office and transfer the writing to OneNote. I’ve tried those “smart pens” and so on to automate this, but it just never works out. Pencil and paper are just fine. As I mentioned, sometime I just need to think. I’ll do nothing, and let my mind wander, thinking of nothing in particular, or some math problem or science question I’m interested in. My only issue with this is that I communicate tothink, and I don’t want to drive people crazy by being that guy that won’t shut up, so I think in a different way. Power, but no Internet or Phone If I have power but no Internet or phone, I focus on the laptop and the tablet as before, and I also recharge my other gadgets. Power, Internet, Phone and a Place to Work At first I thought that when I arrived at the hotel or event I could get the same amount of work done that I do at the office. Not so. There’s simply too many distractions, things you need, or other issues that allow this. Of course, Ican work on any device, read, think, write or whatever, but I am simply not as productive as I am in my home office. So I plan for about 25-50% as much work getting done in this environment as I think I could really do. I’ve done some measurements, and this holds out to be true almost every time. The key is that I re-set my expectations (and my co-worker’s expectations as well) that this is the case. I use the Out-Of-Office notices to let people know that I’m just not going to be 100% at this time – it’s hard for everyone, but it’s more honest and realistic, and I’d rather they know that – and that I realize that – than to let them think I’m totally available. Because I’m not – I’m traveling. I don’t tend to put too much detail, because after all I don’t necessarily want to let people know when I’m not home :) but I do think it’s important to let people that depend on my know that I’ll get back with them later. I hope this helps you think through your own methodology of staying productive when you travel. Or perhaps you just go offline, and don’t worry about any of this – good for you! That’s completely valid as well.   (Oh, and yes, I wrote this at 35K feet, on Alaska Airlines on a trip. :)  Practice what you preach, Buck.)

  • Failed 12.04 installation

    - by Rob Sayer
    I tried installing Ubuntu 12.04 today. Not an upgrade, a new installation. It didn't work. My computer specs: Computer: Compaq presario CQ-104CA OS: Windows 7 Home 64 bit CPU: AMD V140 BIOS: latest Graphics: amd m880g with ati mobility radeon hd 4250 Wireless: atheros ar9285 Internal HD:SATA I wasn't connected to the internet at the time ... I know of a number of people who have installed ubuntu unconnected and just updated later. It seemed to go normally until I got to the part where I chose to install dual boot linux/windows. Then, the screen went black and the following test appeared (I left out the [OK]'s): checking battery state starting crash report submission daemon stating cpu interrupts balancing daemon stopping system V runlevel compatibility starting configure network device security stopping configure network device security stopping cold plug devices stopping log initial device creation starting enable remaining boot-time encrypting devices starting configure network device security starting save udev log and update rules stopping save udev log and update rules stopping enable remaining boot-time encrypted block devices checking for running unattended-upgrades acpid: exiting speech-dispatcher disabled: edit /etc/default/speech-disorder At this point, the CD is ejected. Then nothing. If I press the return key, it boots Windows. I don't think that's what's supposed to happen. Thinking the cd media or dvd drive may have been faulty, I downloaded the .iso again and made a bootable USB stick, as per your instructions. This time there was no cryptic crash screen. It just booted windows. I can't find any log files it may have left. Thinking the amd64 version may have been the wrong one, I tried downloading the x86 version. Same thing, both from cd and usb drive. Note I downloaded both files twice. I doubt it was a corrupted d/l. This is supposed to be a simple, transparent install. I went to the time and trouble of looking up my devices and drivers re ubuntu beforehand, and was prepared to do some configuration, though I know someone who has the same wireless device and his worked righted out of the box. But I spent over 3 hours trying to install it with only the above to show for it.

  • Is it okay to call exception-triggered debugging "post-mortem debugging"?

    - by cool-RR
    I heard the term "post-mortem debugging", and Wikipedia says it's debugging done after the program has crashed. I often debug Python apps using a debugger that stops execution once an important-enough exception has been raised. Then I can use the debug probe to investigate. Does this count as "post-mortem debugging"? Because the program doesn't really crash. EDIT: If the answer is no, then what name would you use for the kind of debugging that I described?

  • Can't sync music on Nexus 4 with rhythmbox

    - by luca992
    My LG Nexus 4 phone running Andriod 4.4.3 will not sync music with rhythmbox, banshee, or clementine with my laptop running Ubuntu 14.04. When attached via USB2 or USB3 I can mount the file system on the phone without issue and can manually transfer files but attempting to sync my nexus with any of the three music players I listed causes them to crash. I realize it is probably some mtp issue. But I cannot figure out why the music players cannot connect to my nexus and nautilus has no problem doing so.

  • Wubi no longer supports install to fakeraid?

    - by Ryan
    About a week ago I used wubi to install ubuntu onto one of my two raid1 devices in windows 7. I tried to do the same this week on the same mobo/drive combo and now I can't get it to install. It gives me first an "invalid prefix" during the install and then says "completing install" followed by a crash into busybox with a warning that the raid can't be mounted because it already was mounted. Has there been a change in wubi or something in the recent past?

  • HTG Explains: Why Do So Many Apps Want to Send Usage Statistics, and Should I Let Them?

    - by Chris Hoffman
    Many programs want to send usage statistics, error logs, and crash reports — data about how you use the application and what problems occurred — to their servers. Some people disable these options, but should you? We’ll look at the exact types of data applications want to send, what developers do with it, whether any sensitive personal data is being passed along, and the advantages and disadvantages to enabling these options.

  • High traffic chat - how to check if there is new message and show it for all users

    - by user2633999
    I already had question about this but obviously it was not accepted very well, apparently too long when it's actually more information so you could have given me better answer. Ok, I will be much clearer now. Best possible logic to develop scalable chat in terms of stability, storing/reading messages on chat, updating chat on new message for all users etc.? I have most of this developed, the logic I think I miss is -- check if there is new message and show it for all users. I have this implemented but it crashes the site due to its traffic of 300k-400k people, so that's my main question. The chat is PHP based and uses Pusher (www.pusher.com) for instant messaging but it lacks what I need because it's more like a websocket. I'm using hardcoded files to keep messages (want to avoid database as much as possible). It's a no extension type of file, I'm sure you know. I'm getting crash with $fp = fopen(..., "w"); // pretend ... is the path and filename fwrite($fp, $msg); //hardcode the message fclose($fp); where $msg is the message itself. I'm having 1 file per message. I show last 150 messages = 150 file accesses and reads, yeah it's too much I guess. I have better logic now which I'm pursuing and that is 1 file with last 50-100 messages at all time. Sure it should be much better. How does it crash, that's the trickiest part because everything seems ordinary, believe me it is difficult to determine what exactly crashes the site, but in like 5 minutes when I try to open the site it's gone, then I put the old content without chat and is back online again. I'm having jquery post every 1 second to check if there is new message. I'm using timestamp in a special file where I keep the time last message was sent and if ((time() - time in file) <= 2) = reload last 150 messages including the last one. Too much input/output, write/read or however to say it I think is what crashes the site.

  • How do I downgrade rhythmbox v2.98?

    - by fossfreedom
    I've been testing out the new WebUpd8 PPA for Rhythmbox which I used to upgrade from Rhythmbox v2.97 to v2.98. However, when I added this PPA, when using my favourite plugins replaygain and coverart-browser, Rhythmbox crashes with a segmentation fault. Worse, when this crash happens, my Unity desktop becomes unstable, with various applications failing to start with similar segmentation faults. Does anybody know the reason for this - but more importantly how to resolve this?

    I have just installed Ubuntu 11.10 (did a fresh install and erased 11.04). After the reboot it appeared a log on the screen, saying all the starting services on the left and [OK] on the right. However, two particular entries, starting automatic crash report installation and starting restore sound card(s') mixer state(s) were set on [FAIL]. After that, Ubuntu did not boot. Is there any way that i can skip those two entries and boot Ubuntu?

  • Requring static class setter to be called before constructor, bad design?

    - by roverred
    I have a class, say Foo, and every instance of Foo will need and contain the same List object, myList. Since every class instance will share the same List Object, I thought it would be good to make myList static and use a static function to set myList before the constructor is called. I was wondering if this was bad, because this requires the setter to be called before the constructor? If the person doesn't, the program will crash. Alternative way would be passing myList every time.

  • SQL SERVER – Introduction to Extended Events – Finding Long Running Queries

    - by pinaldave
    The job of an SQL Consultant is very interesting as always. The month before, I was busy doing query optimization and performance tuning projects for our clients, and this month, I am busy delivering my performance in Microsoft SQL Server 2005/2008 Query Optimization and & Performance Tuning Course. I recently read white paper about Extended Event by SQL Server MVP Jonathan Kehayias. You can read the white paper here: Using SQL Server 2008 Extended Events. I also read another appealing chapter by Jonathan in the book, SQLAuthority Book Review – Professional SQL Server 2008 Internals and Troubleshooting. After reading these excellent notes by Jonathan, I decided to upgrade my course and include Extended Event as one of the modules. This week, I have delivered Extended Events session two times and attendees really liked the said course. They really think Extended Events is one of the most powerful tools available. Extended Events can do many things. I suggest that you read the white paper I mentioned to learn more about this tool. Instead of writing a long theory, I am going to write a very quick script for Extended Events. This event session captures all the longest running queries ever since the event session was started. One of the many advantages of the Extended Events is that it can be configured very easily and it is a robust method to collect necessary information in terms of troubleshooting. There are many targets where you can store the information, which include XML file target, which I really like. In the following Events, we are writing the details of the event at two locations: 1) Ringer Buffer; and 2) XML file. It is not necessary to write at both places, either of the two will do. -- Extended Event for finding *long running query* IF EXISTS(SELECT * FROM sys.server_event_sessions WHERE name='LongRunningQuery') DROP EVENT SESSION LongRunningQuery ON SERVER GO -- Create Event CREATE EVENT SESSION LongRunningQuery ON SERVER -- Add event to capture event ADD EVENT sqlserver.sql_statement_completed ( -- Add action - event property ACTION (sqlserver.sql_text, sqlserver.tsql_stack) -- Predicate - time 1000 milisecond WHERE sqlserver.sql_statement_completed.duration > 1000 ) -- Add target for capturing the data - XML File ADD TARGET package0.asynchronous_file_target( SET filename='c:\LongRunningQuery.xet', metadatafile='c:\LongRunningQuery.xem'), -- Add target for capturing the data - Ring Bugger ADD TARGET package0.ring_buffer (SET max_memory = 4096) WITH (max_dispatch_latency = 1 seconds) GO -- Enable Event ALTER EVENT SESSION LongRunningQuery ON SERVER STATE=START GO -- Run long query (longer than 1000 ms) SELECT * FROM AdventureWorks.Sales.SalesOrderDetail ORDER BY UnitPriceDiscount DESC GO -- Stop the event ALTER EVENT SESSION LongRunningQuery ON SERVER STATE=STOP GO -- Read the data from Ring Buffer SELECT CAST(dt.target_data AS XML) AS xmlLockData FROM sys.dm_xe_session_targets dt JOIN sys.dm_xe_sessions ds ON ds.Address = dt.event_session_address JOIN sys.server_event_sessions ss ON ds.Name = ss.Name WHERE dt.target_name = 'ring_buffer' AND ds.Name = 'LongRunningQuery' GO -- Read the data from XML File SELECT event_data_XML.value('(event/data[1])[1]','VARCHAR(100)') AS Database_ID, event_data_XML.value('(event/data[2])[1]','INT') AS OBJECT_ID, event_data_XML.value('(event/data[3])[1]','INT') AS object_type, event_data_XML.value('(event/data[4])[1]','INT') AS cpu, event_data_XML.value('(event/data[5])[1]','INT') AS duration, event_data_XML.value('(event/data[6])[1]','INT') AS reads, event_data_XML.value('(event/data[7])[1]','INT') AS writes, event_data_XML.value('(event/action[1])[1]','VARCHAR(512)') AS sql_text, event_data_XML.value('(event/action[2])[1]','VARCHAR(512)') AS tsql_stack, CAST(event_data_XML.value('(event/action[2])[1]','VARCHAR(512)') AS XML).value('(frame/@handle)[1]','VARCHAR(50)') AS handle FROM ( SELECT CAST(event_data AS XML) event_data_XML, * FROM sys.fn_xe_file_target_read_file ('c:\LongRunningQuery*.xet', 'c:\LongRunningQuery*.xem', NULL, NULL)) T GO -- Clean up. Drop the event DROP EVENT SESSION LongRunningQuery ON SERVER GO Just run the above query, afterwards you will find following result set. This result set contains the query that was running over 1000 ms. In our example, I used the XML file, and it does not reset when SQL services or computers restarts (if you are using DMV, it will reset when SQL services restarts). This event session can be very helpful for troubleshooting. Let me know if you want me to write more about Extended Events. I am totally fascinated with this feature, so I’m planning to acquire more knowledge about it so I can determine its other usages.
