There was broad consensus that the internet is enabling substantial changes in the way we learn and teach. It has always been possible to learn outside of a school setting. The ubiquitous connectivity and very low cost of content production and distribution seems to enable the unbundling of key components of education.

1) The student (and his/her parents) is increasingly going to take control of his/her education including choice of schools, teachers, classes, and even curriculum. That's what the web does. It transfers control from institutions to individuals and its going to do that to education too.
2) Alternative forms of education (home schooling, charter schools, online learning, adult education/lifelong learning) are on the rise and we are just at the start of that trend.
3) Students will increasingly find themselves teaching as well. Peer production will move from just producing content to producing learning as well.
4) Look for technologies and approaches that reduce the marginal cost of an incremental student. Imagine that it will go to zero at some point and get on that curve.
5) The education system we currently have was built to train the industrial worker. As we move to an information driven society it is high time to question everything about the process by which we educate our society. That process and the systems that underlie it will look very different by the time our children's children are in school.
6) Investment opportunities that work around our current institutions will be more attractive but we cannot ignore disruptive approaches that will work inside the existing system. Open courseware, lesson sharing, social networks, and lightweight/public publishing tools are examples of disruptive approaches that will work inside the existing system.
7) Teachers are more important than ever but they will have to adapt and many will have to learn to work outside the system. It was suggested at hacking education that teachers are like bank tellers in the 1970s. I don't agree but I do think they are like newspaper reporters in the 1990s.
8) Credentialing and accreditation in the traditional sense (diplomas) will become less important as the student's work product becomes more available to be sampled and measured online.
9) Testing and assessment will play more of a role in adapting the teaching process. A good example of this is how video games constantly adapt to the skill level of the player to create the perfect amount of creative tenstion. Adaptive learning systems will soon be able to do the same for students.
10) Spaces for learning (schools and libraries) will be re-evaluated. It was suggested that Starbucks is the new library. I don't think that will be the case but the value of dedicated physical spaces for learning will decline. It has already happened in the world of professional education.
11) Learning is bottom up and education is top down. We'll have more learning and less education in the future
-
niche social networks +blogs + rss feeds/filtered web + games/points systems = niche learning community
-
beginners need structured learning. after a basic foundation, though, learning is done through trial and error, conversation, and unstructured patterns. this is one of the biggest problems with school, way too much structured learning. turns you into a robot.
Gojko Adzic » QCon London 2009: Upgrading Twitter without service disruptions

A very interesting observation during the talk was that Twitter started up with a CMS model and that they gradually moved towards a messaging model. I’ve seen this in a few applications so far, including a casino system, where the messaging model seems to fit best an application intended to power massive community of online users, it seems regardless of what the application actually does business wise. Applications start out completely different, but then more and more functionality gets bolted on top of user messaging capabilities that the whole architecture on the end gets refactored to utilise the messaging channels as the core information transport. With Twitter, I’d expect this to be more obvious from the start as it was intended to help people notify each other.
-
The interesting thing, however, was that all the upgrades were done live, without shutting down the system. The changes were always introduced to one node, then regression issues were sorted out, and then the software would be rolled out to the whole cluster. They went as far as building a whole messaging system based on memcached APIs in order to be able to slot in such changes.
-
a write-through vector cache of primary tweet keys with 99% hit ratio, a write-through row cache for tweets and users with 95% hit rate and a read-through fragment cache with rendered versions of different tweets for different clients with 95% hit rate. All these caches are based on memcached.
-
this change allowed them to increase the web server performance from 3.32 requests per second without caching to 139.03 requests per second. Weaver said that API services work about four times faster than the web, which means that the API performance is roughly 550 requests/s [my calculation, not given during the talk].
-
- Web is only 10-20% of the traffic, the rest is through API services
- Web servers are still 50% of the cluster.
- Regular incoming traffic peaks are around 80 tweets per second. I expected this to be a lot more.
- before the upgrades their web servers shipped only 3.32 requests per second!
- For each tweet, message gets inserted for each user which follows a tweet. In average, a user has 120 followers so this comes to about 9600 messages/s at peak times
- Message servers run on three nodes. They decided to write their own messaging software in order to make the protocol memcached-like, and did not evaluate other available solutions.
- During Obama’s inauguration, they peaked at about 350 tweets per second for around five minutes.
- They had a ton of problems with garbage collection but strangelly haven’t looked into JRockit RT or something similar that has predictable GC. Twitter JVM middleware runs on the SUN JVM

Most of the tools used by Twitter are open source. The stack is made up of Rails for the front side, C, Scala and Java for the middle business layer, and MySQL for storing data. Everything is kept in RAM and the database is just a backup.

Update 6: Some interesting changes from Twitter's Evan Weaver: everything in RAM now, database is a backup; peaks at 300 tweets/second; every tweet followed by average 126 people; vector cache of tweet IDs; row cache; fragment cache; page cache; keep separate caches; GC makes Ruby optimization resistant so went with Scala; Thrift and HTTP are used internally; 100s internal requests for every external request; rewrote MQ but kept interface the same; 3 queues are used to load balance requests; extensive A/B testing for backwards capability; switched to C memcached client for speed; optimize critical path; faster to get the cached results from the network memory than recompute them locally.

How do you handle notes and ideas?

I write between ten and a hundred notes each day. Sometimes I add to an existing note or document. I have trouble working with notes, documents, ideas and streams of thought.
Do you recognize this? How do you handle it?<p>Do you keep notes in one place? How do you accomplish that? How do you handle physical notes and non-physical notes? Do you try to gather all notes online? Where and how? -
I don't.
Like you, I probably have about a thousand different ideas and streams of thought during the course of a day. Unlike you, I don't write any of them down.
I do this because there is no way I'd get anything done if I didn't. I don't mind forgetting some key insight, because if it was important or relevant enough, it'll translate into sometime I will write down when the time is right. If not, it's probably something that I shouldn't bother wasting my time with. (That's not to suggest it isn't valuable).
You only have so many hours in the day to work on so many things. People like us need to ignore our own brain 80% of the time to be productive. It's a curse really.
-
Org-mode is nice for two reasons: first, it gives you a way to organize projects and sub-projects and meta-projects. Second, it's a reality check -- if you gave yourself a task that in no way advances any goals you've already stated, org-mode's organization scheme means that you end up either creating a new goal or admitting that a new project isn't worth your time.
-
I wasn't happy with any of the solutions out there so we built our own.
We treat notes as a stream and you categorize notes using hashcodes.
We have an iPhone and Android client so you can easily include pictures in your notes.
We aren't live yet, but will be in a few weeks. =)

jott.com and reqall.com - both have iphone and blackberry apps
-
Thanks, we've looked at those before and they still seems a bit too complex. I do like their audio-text bridge.
We are building something even simpler, a personal syslog synced across phone/web/command line.
-
Fundamentally we view notes as a stream like a log file or Twitter.
You will have one place to easily and quickly dump everything, then be able to grep out the relevant information, and then late bind the decision on what to do with that information.
-
I have 744 "Drafts" to myself in GMail.
-
Ditto. But I manage (somehow) to loosely categorize them: there is an (ever expanding) message with Music, Movies, Books and other media that I want to look at.

EVERNOTE!
I can't say enough good about this program. i use it everywhere (mac, web, macbook, iphone). it's certainly not perfect (auto indent?, the ability to copy check boxes) but it is certainly good. I use a moleskine too, but for searching and loading up data, and keeping task lists, with pictures! Evernote has made me very happy.
this question was asked awhile back on HN and that is how I found out about. I've tried various things in the past, but evernote has worked great for me. evernote.com.
-
I second or third that. Great on the mobile phone for uploading quick notes and pictures.
Evernote is to my memos what dropbox is to my work in progress files.
-
Onenote is great indeed. Possibly underrated because it is a MS product, but it is great for note taking and syncing those notes to pda or mobile phone.
-
Warning, Mac-centric answer:
For task lists, I tried a bunch of things at one point, and only one that stuck was Taskpaper (http://hogbaysoftware.com/products/taskpaper). It's so simple that I actually use it. I've been using it for about a year now on a sustained basis. It has simple emacs keybindings, like other OS X text editors, so that's nice for me too.
For ideas best expressed by complicated freehand drawings, I use pen and paper. I always carry an unruled (no lines) notebook for this purpose.
For a while I was using a small drawing tablet and Curio (http://www.zengobi.com/products/curio/) for drawings, but it didn't stick. The GUI was a little too slow, and plugging in the tablet was too much of an extra step. A tablet Mac would solve this. (Yeah, yeah I could get a PC, but I'd rather avoid it if I can.)
When I take notes at a meeting or a talk, I use TextEdit (again, w/ simple emacs keybindings), and depend on spotlight to help me relocate things. I prepend all filenames with the date in <2 digit year><2 digit month><2 digit day> format, so by default things sort by date across filesystems etc. This is surprisingly useful.
-
Luminotes.com or Google Notebook.
On the go? Moleskine
-
I was in the same boat, taking at least 10 notes in a session, several times a day. I work best by blasting notes in and sorting through them when I come up for air. There wasn't anything that allowed me to work this way very effectively, so I did what any of you would have done - started a startup, of course!
We are live, you can check us out at the link below:
-
I'm currently trying different systems, and to be honest, I'm not 100% happy with any of them.
Started with the lovely and simple Notepad textfiles, but after a bit they are too simple and too hard to maintain, thus not good.
Then I used Google Notebook for a long time, was easy to add stuff, but not so easy to find it later. Plus it's still too simple for my liking, can't categorize ideas too well.
I switched recently to Evernote, which seems to be an improvement over Google Notebook, but for some reason I still don't feel comfortable with it. The fact that I can type offline and sync with different computers or read my ideas online is really welcome and handy, though.
Everytime I fall back to my paper notebook, which is also too simple and not search friendly, but I like handwriting and for some strange reason, ideas flow much better than when I write rather than type them. The real only grudge I have with it is that there is no backspace key and no "insert a new line in the middle of the text" either :(
What do you use to organize your thoughts for a new website or project?
-
balsamiq is great for ui mockup. Other than that I agree with habs, paper works. Although i have recently started using Microsoft One Note 2007. It makes for great brainstorming / idea throwing / white boarding.
-
I like to use mindmaps for planning and concept work like this.
Freemind is a good open source mindmap editor for the desktop.
Or you could try my online, browser-based mindmap app. http://thoughtmuse.com ;)
-
I'm currently on my second project and for both (and everything else) I use two tools:
Xmind Mind Mapping: I paid like 120 bucks for it, now they decided to open source it (that I did not like much, but now you can get it for free!) Their software is amazing.
http://www.xmind.net/MacJournal: Quick notes, texts, transcripts, voice notes, video notes, etc I have in there. They have full screen writing which is amazing.

http://www.balsamiq.com/Final UIs and documentation: Axure Pro (Windows only :( ) (VMWare anyone :) )
http://www.axure.com/Creating manuals, customer support and FAQ: ScreenSteps. (I cannot recommend this software enough! AMAZING)
http://www.bluemangolearning.com/screensteps/Project Management: Merlin. Fantastic software.
http://www.projectwizards.net/en/Sales and CRM: Daylite. Just started using it. Very powerful, but the learning curve is steep.

If you’re like me, you’re working on many things at once. You’re continually developing, doing research, fixing bugs, helping people, etc. When it comes time to do your status report, how do you remember what all you did this week? When you see a bug that looks a lot like one you fixed two months ago, how do you remember what you did to fix it? The solution is simple, and yet I find many developers don’t do it. Take notes. You should take short, but informative, notes as you work, on all the things you work on that day. These notes don’t have to read like the next Great Novel. The purpose of the notes is to trigger your memory into remembering what you were doing when you took the note.
-
This is really all you need. There are some specialized note-taking tools that work well, however. When I’m in a Microsoft Windows environment, the Microsoft OneNote program is excellent. It has facilities for putting notes in folders, within projects, as you would expect; but it adds things like being able take screen shots, and then index the text in that screen shot so that you can search on it later. That’s useful for when an error message pops up in a dialog box and you need to capture its contents. You can highlight text, tag paragraphs, etc. etc. But for 95% of my professional life, I’ve just been grepping text files, and like I said, that’s really all you need. The important thing is that you capture the information.
-
I couldn’t agree more. I’ve been taking notes like this since a couple of years and they have been a real time-saver.
I have never used OneNote, but I’m eager to suggest WikidPad as a great alternative: open source, actively developed, no-nonsense, written in Python and customizable to the bone.
-
I find the Harvest Co-op app (http://coopapp.com) to be ideal for this. It is like twitter for teams, and if you use Harvest for time tracking Co-op allows you to track time, too, by linking to your harvest account. Handy.
Harvest is at http://harvestapp.com
I don’t have anything to do with Harvest, btw, just a happy customer.
-
I started seriously taking notes when I switched from networking to programming in 2005. It took a while to find a tool I liked but I came across Confluence and have been very happy with it since then.
-
I’ve been taking notes like this for about three years now and I have to admit I still haven’t got it perfected yet. In the beginning I took verbose notes detailing everything I did, but after a few months it became unwieldy to go back and manually search through a hundred pages of notes trying to remember where I might find that detail I knew I had seen.
It was a little better when I finally started doing everything on the computer, but invariably it seemed like I was recording a lot of information that I never ever needed again, and spending a lot of time doing so, and when I did need some tidbit of data it wound up being the one thing during the day in question that I had considered unimportant or for whatever reason had not documented.
I’ve sort of had to resign myself to simply keeping a whiteboard with items that really stand out, such as stupid bugs that I fight for half the day only to find there was some tangential solution that really should be unrelated to what I am doing (”oh! my program isn’t working because the router needs to be power cycled!”). -
I’ve been using OneNote for a little while now for tracking daily status for stand-ups, and it’s pretty much what I need - good WYSIWYG editor, search, groups, etc.
Picking the right tool up-front seems pretty key, cause once you have a few months of notes written, it’s tough to switch.
Good post.
-
I’ve been trying to do this for a while. Getting into the habit is the hardest part. I tried a paper notebook a week or two, and then made a Google Docs Spreadsheet with a single entry form. It adds a timestamp to the spreadsheet automatically, and I’ve got it in my toolbar and on my phone home screen, so I can make entries anywhere.
-
I am the sole note-taker in the group which means that I get asked the questions about what we did and when. I use Evernote (non-synced) and record daily activities. I also set up a personal wiki on my server so that other people can access notes that I have taken. I have to use a windows machine at work so I use screwturn wiki (it was tough to get that unblocked!)
Also, time tracking with Rachota is a breeze! I have turned 2 of my 3 co-workers on to it.

The best Web-based task managers. - By Chip Brantley - Slate Magazine
-
For years I've managed to make this clutter work for me. But this spring, I noticed that too many of my to-dos were not getting done. (Take this assignment, for example. Between its official due date and the day I actually filed it, two and a half shameful weeks passed.) With a book to finish, a business to manage, and a big move to make, I decided that it was time to find and commit to a proper system of task management.

I don't think the author did a very good job of making the case that people are thinking less due to the web.
-
I'd rather spend my deduction and imagination time on problem solving than information gathering.
Or to be more specific: I'd rather spend my deduction and imagination time engaged with my peers on solving problems, than sitting in quiet contemplation of information that I do not have convenient access to.
-
Why is your "deduction and imagination" time a fixed quantity? The thrust of the argument in favor of learning through books rather than the internet is that you will spend an equal amount of external problem solving time, but more internal problem solving time as part of the information gathering process.

The simple printed book is much more conducive to promoting thinking than the sophisticated Web. If a book does not provide all the information that one needs, some of the information has to be deduced and some of it has to be imagined. When people do not get answers to their questions by reading one book, they have to read a second or third book to find the answers. The book is also a slow medium. By the time a person buys, borrows or finds another book that has the answer to a question, he or she also has had the time to think about it more thoroughly and perhaps even refine the question. The time spent in thought will in many instances enable a person to generate an answer to the question that aroused his or her curiosity in the first place.Add Sticky Note

As they click on one hyperlink after another, they often forget the initial question to which they were trying to find an answer. This is because the Web offers many distractions to its users in the form of ever changing content, links that are either obsolete or lead to completely new and different Web sites, and pop-ups and banners that advertise goods and services. Often times, as people aimlessly click their way through cyberspace, hyperclick hysteria sets in, and people lose their bearings in cyberspace and have to click their way back to more familiar cyber territories.
-
Long before human beings established a settled way of life, we were wanderers. Deep inside, human beings are still wanderers. The Web provides human beings an opportunity to fulfill their desire for wandering by thoughtlessly clicking and roaming the cyber wilderness. Since new Web pages are created everyday, the Web continuously offers wanderers new territory to explore. As interactions with the Web increase, the clicking and wandering behavior gets more deeply entrenched among human beings. Such aimless cyber wandering eventually becomes a substitute for meaningful thinking.
The Mobile Challenge | Union Square Ventures: A New York Venture Capital Fund Focused on Early Stage & Startup Investing
-
The challenge for startups (and investors!) has been identifying opportunities that are "native" to the new platforms. By "native" we mean opportunities that simply did not exist previously and cannot exist without the phone. For instance, we would not consider delivering breaking news to a mobile a native opportunity, as a startup rarely has a better chance of being "CNN for mobile" than CNN does.
-
We don't know which native applications will emerge as ones that combine these unique capabilities and new behaviors into true breakout services, but here are some categories that we find interesting along with some of the challenges that they face:
* Location-based social networking, such as Loopt, Brightkite and foursquare. The big question in this category is whether these new networks will gain enough scale that they can compete effectively with the mobile offerings of existing social networks, or if the mobile networks differentiation in value proposition will be insufficient to overcome the current gap in scale.
-
* Shopping applications will likely be interesting and there has already been an early exit with SnapTell being acquired by Amazon. Most US-based mobile shopping applications simply supplement the real-world shopping experience with more information (barcode scan sending you to Google, BBB, Consumer Watch info, price comparison, etc...). This behavior contrasts with Asian markets where actual commerce/checkout via mobile is far more prevalent. We're interested in seeing if the unique capabilities of smartphones will accelerate mobile shopping all the way through checkout on the phone.
-
There is a good chance that the truly breakthrough application category is not on this list. It will be obvious in hindsight but a lot harder to anticipate. If you are working on a native application, please tell us about it.
-
In addition to the native categories you listed, I'm interested in the idea of my smart phone as an internet gateway for "dumb", cheap, bluetooth-enabled sensors and devices. The Nike+ iPhone app is an early example of this. It doesn't make sense today for your running shoes to be fully-featured, internet connected gadgets on their own. Instead, you have a cheap, dumb sensor in your shoe that simply transmits data to your phone, then your phone does the more complex work of getting that data onto the web and providing an interface for the experience. I can picture a ton of other businesses emerging from this idea of dumb sensors plus smart phones. I might wear a wristwatch that transmits my heart rate to the web. My car might send maintenance updates to the web via my phone's internet connection. Retail merchants might transmit data and offers to / from my phone when I walk into their stores. I see lots of business opportunities in this area.
-
That's exactly what our solution was designed for. It essentially a mobile app with an Open API. You can attach a sensor to the phone via Bluetooth, transmit that data to our app and then we send that data (you have complete privacy controls) to any web server. The way we do this is to take the meta data and add it to the outgoing HTTP headers. So now all you have to do is read the incoming data at the server. We even have a windows mobile version that you can now access any device side data using JavaScript all from within the mobile browser.
-
Great post. One key "native" functionality I think you forgot to mention was the fact that our mobile devices have access to our contact list. I know in my case my BlackBerry often times contains the most current set of contacts I have (I can't wait until they put Xobni on BB--should be similar to how Palm's WebOS can auto-detect details from Exchange, Facebook and LinkedIN).
It's the intersection of your media assets, location data, contacts list, audio/video/touch inputs and data connectivity that make the mobile device the ultimate "social tool". -
I'm a believer in the intersection of touch & ubiquitous connectivity as the combined killer-feature. It's not just about content consumption- you can do really amazing (rich, detailed, structured, intuitive) human-powered data capture on these devices.
At GameChanger we use the term "User Collected Data" to distinguish that from unstructured UGC. Things that used to require paper input, laptop tabulation, or heavy/expensive/complex recording equipment can now be accomplished on-location with one hand free. -
However the cell phone (mobile phone) is also notable as a notification and billing platform. Mobile platforms have been able to charge for content, where the web has failed miserably (pics, vids, music). Customers don't blink at the idea of paying to send a 140 character message, when email is free for almost unlimited characters.
Put it all together and you have viable business models in paid proximity notification.
Ronan
Locle.com -
Food for thought - it's important to keep in mind that mobile apps do not always require human involvement. The amount of interest in machine-2-machine applications is set to explode. These apps do not need a GUI/browser at all and can be based on net-connected CPUs running from within mobile assets such as trucks, ships, golf carts, etc etc. I expect to see some very interesting apps emerge from this space.
-
I believe one of the key difference of the mobile web is context which can drive impulse behaviour. It is not necessarily a technical difference via fixed web ... but a mental one.
For example, you're at a concert and you want to share the moment with people that aren't there through twitter, pictures and video. Much less interesting the next day through your PC. You want to find your friends at the concert so you use location. You decide to buy a shirt and text a payment so you can just pick up your shirt after the show or have it delivered.
The point is context + impulse is a really big deal and if done right, can be a significant opportunity. At favequest, we're applying these concepts to the events market and are adding such capabilities to our platform.

Five years ago, most newspaper editors would have laughed at the idea that blogs might one day offer serious competition. The minicomputer companies laughed at the early personal computers. New technologies often don’t look very good in their early stages, and that means a straightup comparison of new to old is little help in recognizing impending dispruption. That’s a problem, though, because the best time to recognize disruption is in its early stages.
-
An early sign of impending disruption is when there’s a sudden flourishing of startup organizations serving an overlapping customer need (say, news), but whose organizational architecture is radically different to the conventional approach. That means many people outside the old industry (and thus not suffering from the blinders of an immune response) are willing to bet large sums of their own money on a new way of doing things. That’s exactly what we saw in the period 2000-2005, with organizations like Slashdot, Digg, Fark, Reddit, Talking Points Memo, and many others. Most such startups die. That’s okay: it’s how the new industry learns what organizational architectures work, and what don’t. But if even a few of the startups do okay, then the old players are in trouble, because the startups have far more room for improvement.

产品部门在选人这一点上,可以用四个字概括——以文取人。我们不看重简历上的背景,性别,血型,而是根据他写的产品分析看这个人对于产品和用户的感觉,这些感觉是从文字上可以感觉到的。而判断力是源于自己对于产品和用户的感觉积累,当你读过一千个或者更多的产品分析后,再读到一篇产品分析的时候就会一下子给这个分析打一个准确的分数。另外从产品分析里的方法运用上可以看出这个人发现问题和分析问题的逻辑能力。
-
“以文取人”之后,还要看这个人是否喜欢并能够投入的做这个工作。喜欢的投入,和没有感觉的投入呈现的效果完全是两码事。俞军举了一个赛车的例子,他说,有些人开车,就是开车,把车作为一个工具把自己送到目的地,所以开了一辈子车,还是一样的开车。但是赛车手会琢磨怎样把车开的更好更快,所以也许赛车手开一个月的车,就已经比开一辈子车的人开的好的多了。我们需要选的人,就是喜欢并愿意投入的人,在又酷又炫的搜索引擎领域,这样的人可能并不难找。
-
俞军在总结选人经验时,特别强调了要选择和公司,团队的价值观一致的人,这样会大大提升工作的效率。更应该遵循“宁缺毋滥”的原则,宁可人少,每个人累一点或是少做一些事,也不要盲目扩充人力,种下不良的种子。
-
给他成功与犯错的机会——用人的关键在于授权
选对人之后就要考虑如何用好他(她),培养他(她),不能浪费人才资源,这也是本次讲座的重点和意义,引起了在场同学的广泛关注。俞军说首先的一个大原则就是要——充分授权,目标管理。充分授权能够提高人的主观能动性,而目标一定是协调后达成一致的目标。对于产品部门而言,和不同的产品团队合作,就会做出不同的东西,因此依赖于脑力劳动的工作,能动性是非常重要的。
-
另外就是要营造平等的工作氛围,有试错的心态,并能够不断总结。平等的氛围有助于发挥个人能动性。对于试错的心态,俞军分享自己带团队的经验,他说当自己和团队的成员出现意见不一致的时候,要尽量在把控关键点前提下将“试错”的机会留给团队成员。因为如果这个成员的想法此次被证明是错的,那他(她)就会从“错”中学到最多的经验,从而尽快成长。如果领导的意见被证明是错的,那团队成员将没有机会获得“错事经验值”。最后总结尤为重要,总结要有开放的心态,多总结不好的方面,下次可以得到更好的改善。之后再与团队成员互相分享,整体成长会很快。
-
俞军提到应该“助理比经理更懂,经理比总监更懂”,越专注细致的了解一件事情的人最有发言权。最差的方式就是向上分享,单线汇报。真正需要做的是和自己的团队商量,得出什么样的结论,基于事实本身推出结论。需要培养个人持续否定自我的精神,最终的结论是靠发现更多的不足找到,而不是推销观点,永远站在事实的一边,结论会越来越正确。
用人时一门学问,需要大处着眼,小处着手,就像下一盘棋。人才培养,是一个厚积薄发的过程,需要高瞻远瞩,也正如一盘棋局。培养人才,用好人才,才能赢得这盘棋,做好这个项目。
-
用心培养的人才,应该怎样留住?最后俞军总结了吸引人才最重要的三个条件,一是公司的愿景,是否足够吸引人才留下;二是工作空间,是否能够提供发展和上升的空间;三是个人待遇。对于每一个在百度工作的同学来说,我们其实正在合力做一件非常有意义的事情,做中国最好的搜索引擎,降低人们获得知识的成本,填补人们信息的鸿沟,每一个百度人都有理由骄傲和自豪!
-
两个小时悄然滑过。抓住难得的与俞军可以交流的机会,大家也开始在人才选择培养之外踊跃提问有同学问:“你认为百度成功的原因是什么?”俞军说:“是在正确的时间做了正确的事情,那个时候,如果没有百度,也一定会有另一个中文搜索引擎兴起,而百度在这个最佳的时机选择了这个领域,且做得最好,所以这种成功可以说是天时地利的必然。

Match index types to the type of comparisons you perform.
When you create an index, most storage engines choose the index implementation
they Match index types to the type of comparisons you perform. When you
create an index, most storage engines choose the index implementation they will
use. For example, InnoDB always uses B-tree indexes. MySQL also uses B-tree indexes,
except that it uses R-tree indexes for spatial data types. However, the MEMORY
storage engine supports hash indexes and B-tree indexes, and allows you to select
which one you want. To choose an index type, consider what kind of comparison
operations you plan to perform on the indexed column: -
If you use a MEMORY table only for exact-value lookups, a hash index is a
good choice. This is the default index type for MEMORY tables, so you need
do nothing special. If you need to perform range-based comparisons with a MEMORY
table, you should use a B-tree index instead. To specify this type of index,
add USING BTREE to your index definition. For example:

In computer science, a B-tree is a tree data structure that keeps data sorted and allows searches, insertions, and deletions in logarithmic amortized time. Unlike self-balancing binary search trees, it is optimized for systems that read and write large blocks of data. It is most commonly used in databases and filesystems.
在线软件业三年内难以赚钱_业界_科技时代_新浪网
-
不过,众多软件厂商还是把宝押在了SaaS身上。这个道理非常简单,中国管理软件市场的未来在中小企业,而目前的中小企业仅注册的就有4300万家。“如果每个企业一年使用1000元的服务,那么这个市场将会有多大?”软件行业专家黄建强反问说。
-
杨祉雄算了一笔账,要做一家拥有千万级收入的在线软件服务企业,必须得有10万以上的付费用户。那么涵盖的中国中小企业群体至少也要在200万家以上。
目前即便是在线用户最多的阿里软件也不过拥有30万的用户,这个数字距200万中小企业覆盖面也差得很远。而传统的企业管理软件厂商在之前20年间积累的用户总数还不及这个标准的一半,譬如用友花了22年积累了大约70万用户。
