What is using up all my disk space? (Linux)

Running out of hard disk space is a common problem – Linux is not immune!

To see your hard disk usage, open up a shell (eg: ‘gnome-terminal’) and run:

df -h
(the -h option puts the results in a human readable format. eg: 1.5 G (gigabytes), 147m (megabytes))

Here is a great linux command to quickly see who is taking up all the hard drive space:

/usr/bin/du -Sx | sort -rn | more

On a big hard drive this might take 30 seconds or so.

Or to list the files in one directory in order of size do:
ls -S | more

The first command is so helpful I like to make an alias for it.

To do this edit your /etc/bash.bashrc and create an alias at the bottom of the file:
alias dumega='/usr/bin/du -Sx | sort -rn | more'
(I use ‘vi’ as my command line editor. You could use ‘gedit’, but be careful when running it as root)

Now when you are worried about hard disk space, you can simply run ‘dumega’ from the shell and get a summary.

Ridley Melbourne

The college where I studied my MDiv has changed there name from Ridley Theological College to Ridley Melbourne Mission and Ministry College. They are undertaken a whole change of strategy and vision under the leadership of Peter Adam.

This is a very exciting time for the college. If you are looking for somewhere to study or invest financially in a worthy gospel cause, I couldn’t think of a better place.

Is Google watching your hands or reading your brain!?

I just realised Google even detects when your hands are in the wrong place on the keyboard!

For example, if you are a touch typer, but you accidently have your right hand placed one key too far to the left, then instead of typing “google” you will type “giigke” in your google search. But Google will omnisciently realise your error and suggest the what you intended:

A similar case is if your hands are in the wrong place when you type “Amazon”, instead you will search for anazib. But google will figure it out:

Is it just me or is this impressive? Is there anything Google can’t do?! 🙂

Can anyone else find other examples of Google correcting “touch typing in the wrong start position” words?

Reading: David F. Wells, “No Place For Truth, or, Whatever Happened to Evangelical Theology?”

Protestant evangelical churches have grown numerically in leaps and bounds in the 20th century. But is all growth good? Is there any case to be made that evangelicalism has “sold-out”?

This well-regarded book, over a decade old now, is an analysis of what has happened to (American) evangelical churches in the last 100 years, trying to see how “modernity” has contributed to the theological thinning out of American evangelicalism. It is the first of a series of 4 books on the state of evangelicalism in America. The books are very USA-centric.

Wells argues that modern Western culture has had the effect of diluting or even “banishing theology from its place in the center of evangelical life” (p136). He sees modern evangelicals retreading the path of traditional theological liberalism, a path which has been proven to be spiritually bankrupt.

It is a difficult and challenging book. He seems to slide awkwardly between carefully accumulating evidence to build a case, to simply providing anecdotes to illustrate what he assumes is going wrong. Either way his analysis “feels right”, even from the perspective of Australian evangelicalism. It is a sobering, negative assessment.

I have accumulated below some significant quotes from the book that struck a chord with me:

Website Review: “Whirlpool – Australian Broadband News”

Whirlpool is an amazing establishment. It is basically the place to go if you are interested in the state of broadband in Australia, or anything to do with the internet or computer technology.

If you are interested in finding a broadband service, use the Whirlpool “Broadband Choice” section which helps you compare and contrast broadband plans from different ISPs (Internet Service Providers)

The Whirlpool FAQ’s and WIKI are excellent up to date sources of information. For example, when trying to get DSL broadband to my house, I found the Whirlpool “RIM and Pair Gain FAQ” a great source of technical information about what was happening in the new housing estate I was living in. When I was requesting the service I knew exactly what was going on.

The hidden gem within Whirlpool are the amazing forums on the site. At the time of writing they have over 150,000 memberships. Most forums on the web are lame ducks, but the whirlpool forums are great places to get free technical support or ask questions about the internet/computers/broadband and more.

My favourite part of the forums are the ISP sections. They have sub forums for all the major Australian ISP’s. So you can read threads concerning current user experiences with Bigpond, Optusnet, Internode and more. These are a great place to go if you have a gripe with your ISP, you can probably find out if other people have the same problem. For example, many Optus users, including myself, have experienced very slow international speeds in the second half of 2006. Officially Optus has all but denied these problems. But in the relevant Whirlpool discussions you will find some great technical analysis of the problem from smart people who use Optus. Basically these forums are a great alternative to actually ringing the official tech support of your ISP.

The great thing about Whirlpool is that it is an independent and relatively ad-free site that actually allows the public to pool knowledge and experience. It empowers ISP and technology consumers with information. Love it.

Book Review of Iain H. Murray’s “D. Martyn Lloyd-Jones: The First Forty Years (1899-1939)” and “The Fight of Faith (1939-1981)”

Martin Lloyd-Jones (MLJ) was a Welshman and one of the great preachers of the 20th century. He famously put aside a bright career in medicine to go into Christian ministry without any formal theological training. He went on for over 40 years to powerfully preach the Word of God over 3 times per week. Murray has produced a wonderful two volume biography of this great mans life and ministry.

The Future of Television

I have discovered the future of TV. It is beyond BitTorrent, beyond digital broadcasting.

What if you could achieve the following:

– Watch nearly any TV show at any time in any place
– Only requires a dialup connection, not broadband
– Costs nothing (other than internet costs)
– Has no ads or commercial breaks.
– Allows you to avoid sleazy images.
– Doesn’t break any copyright laws.
– Allows you to enjoy highest definition TV in any room of your house without having to sell your soul for a plasma screen.
– Allows you extra deleted scenes not even on the DVD extras.

Would you believe me?

The answer is: reading TV scripts. Tonight I watched (read) 2 Seinfeld episodes in 20 minutes!!! I also read a whole Lost episode in about 10 minutes. Not much happens in one episode of Lost. Just google search for the TV show name and the word “script”. Really they are just fan transcripts, but on some sites you can find original pdf’s of the scripts used by the producers (with slight differences to what was made).

It works for Seinfeld anyway – it is still funny reading just the Script.

I have seen the future of TV and I call it: “reading”.

Another faddish bandwagon or The End Of The World As We Know It?

I hated the Y2K bug movement. I hated the hype. I laughed at people stocking up on food and water. I worked in the IT industry and everyone in the industry knew it was a joke, albeit a very good money making one. Y2K was a “boogey man” for gullible insecure people.

These past months I’ve been reading about the “Peak Oil” movement. This is the concept that Western energy hogging lifestyle (which is inherently wrong) is about to hit the wall. As oil reserves around the world pass the half-way mark, oil suddenly becomes alot more expensive, the oil wars begin (Iraq anyone?) and the western suburbian lifestyle either becomes a nightmare apocalypse (fast crash) or a serious long term recession/great depression (slow crash). I think a slow crash is more likely for Australia, we have enough local fossil fuels (coal/natural gas/nuclear/the oil we stole from East Timor) for basic survival.

There is a real “Occam’s Razor” style argument to this movement. That is: if they are right, it will be TEOTWAWKI (as they say). If they are wrong we you have nothing to lose (+ you will have a great home vegie garden and be out of debt!).

From a Christian perspective there are interesting twists. In theory, Christians should abhor the rampant selfish materialism of Western suburbia. We should decry the fact that cheap oil has allowed us to enjoy cheap clothing and products all produced in 2nd or 3rd world nations with living standards that are extreme poverty. Problem is Christians in the West are not much less selfish than anyone else. Is “Peak Oil” God’s wake up call? Christians in the West are becoming increasingly invisible and irrelevant. The real numbers in Christianity are in the developing nations anyway. I just bought a copy of Jenkins’ “The Next Christendom, The Coming of Global Christianity”.

Anyways, if you want to read more, here is a recent “State of the Union” address from a Peak Oil leader.

Helen and I recently watched “The End of Suburbia”, a great documentary on the subject.

Maybe it’s time to retrofit the suburbs? How can Christians and Christian communities show leadership in the face of all this?

One of the ironies of the whole preparedness movement is that you have to keep buying stuff in order to escape the consumeristic lifestyle. I’m off to buy some bags of rice, and jerry cans, and survival manuals, and home vegetable gardening books, and …

Colin Gunton on the Trinity

These days everyone is writing about the doctrine of the Trinity. It is very popular. I have been reading some Colin Gunton, who is a great exponent of classical Trinitarian theology (ala Nicene-Constantinople Creed), without drifting off into the confusing wonderland of other significant 20th century theologians (names withheld to protect the guilty!).

The two books I have been reading are, “The Promise of Trinitarian Theology” and “Father, Son and Holy Spirit”. Sadly Gunton died in 2003 and was unable to complete a major project in Trinitarian theology.

Here are some notes that I found helpful and interesting from Gunton’s books…

Sermon Series “On Being Human”

This church series is called “On Being Human”. The title (not content) was inspired (stolen) from a series of AFES talks by Philip Jensen.

The idea was to lift up peoples estimate of what it means to be a human – as an image bearer, and the significance of God’s Son taking on our humanity forever.

The series is probably less about what it means to be a human (all applied preaching and Bible teaching is about this!) and more asking the question: “What is the worth of a human being?” or “Where does my worth come from?”.

I was inspired by this quote from Calvin:
“It is certain that man never achieves a clear knowledge of himself unless he has first looked upon God’s face, and then descends from contemplating him to scrutinize himself”
(Institutes I.I.2)

As I read this quote I think I failed to come close to achieving what I set out to do: help people see who they are by looking their maker and looking at Jesus Christ as the perfect human and by seeing we are God’s property by virtue of creation and salvation (especially). It was worth the attempt!

If I had more talks to add, I would add one on “The Future of Humanity”. And possibly one on the entry and effects of sin in the world.

The talks were produced under heavy time pressure, and preaching topical is not my main style of preaching, but it still worth putting them online for feedback. hint hint!

Mini Review of Google Print

Is there anything Google can’t do? They keep doing amazing things.

I already love Google Print.

It allows you to do full text searches on books, real paper books!

e.g.: Do you want to find a quote from Peter Adam’s book “Speaking God’s Words”? Type in the book title into Google Print, click on the book and you can search within the book!

Imagine you are doing some thinking about “eternal punishment” and know that John Stott had some significant views. You can do a search on “John Stott eternal punishment” and find 15+ references to books discussing his position! (this would be great for theology students)

This is a great tool for the preacher and pastor. Especially those who cannot afford large libraries. Even for those who can it is a great time saver.

Imagine what a resource this is for the pastor or missionary in a developing country?!

Currently there are some small problems:

  • The interface is clunky and not as usable and simple as other Google pages. This should improve over time.
  • Some books have not given permission to be part of the project. This is annoying, but Google still has them in their system and will still give you the page numbers for the results! (I’m guessing in time all authors + publishers will realise the benefits of allowing the full text to be shown)
  • There are lots of books not yet in the system, but somewhere Google have machines (or people) madly scanning books in.

You might ask, how do Google make money off this? Well they have links to book sellers where you can actually by the books, and they also show ads for you to click on.

OpenOffice.org 2.0 is out!

Don’t pay money for bug-ridden Microsoft Office!

Use OpenOffice.Org 2.0! It fully supports Microsoft formats. It can automagically export to PDF format! (Microsoft have announced they are copying this feature in the next version of Office).

OpenOffice.org has a word processor, spreadsheet and powerpoint equivalent. There is no Access replacement though.

It runs on Microsoft Windows, Mac and Linux. The easiest way is to run a system like Ubuntu Linux, which comes with OpenOffice prebuilt and ready to go.

OpenOffice is what used to be called Star Office. In fact Sun still release a $$$ version of Star Office but it is not worth it. OpenOffice will do the same thing.

OpenOffice is not without problems. It is somewhat slow and bloated itself. I still have a soft spot in my heart for AbiWord and Gnumeric.

Ubuntu Breezy

I have been using Ubuntu Linux 5.10 (Breezy Badger) on my PC for a few weeks now.

Ubuntu is nice. I switched from Fedora Linux to Ubuntu Linux in the search to stop my pc crashing, which turned out to be a hardware problem.

Now that I am on Ubuntu I can’t really go back. The packages available for it are wonderful – sometimes they are a bit dated but it is better than the Fedora updates mess. I still get some Debian nightmares using it though.

Ubuntu supports rt2500 cards in the kernel. The installer didn’t set it up for me, but at least I didn’t have to compile the kernel module. I was able to use the nvidia driver out of the repos which was nice and easy.

Note: if you can’t get your usb sticks or mass storage devices to work: you need to edit the file /etc/group and add yourself to the group called plugdev. I dunno why this is so, it is quite annoying. You also need to add yourself to the scanner group for similar reasons.

I even noticed today all the pc’s in the Ridley library have Ubuntu on them!

Ubuntu supports my intel 915P chipset sound card, my digital camera, mp3 player, scanner, printer. When installed it has my office software, web browser, email client, podcast client, rss reader, bittorrent client, music player, photo editor, sound editor, basically everything I want – plus more creative linux only things like the Tomboy notes editor which I use for my daily ToDo lists etc.

All of this is Free Software. Amazing.

Has post-modernism self-destructed yet?

Some web sites make me wonder whether the inevitable self-destruction of post-modernism has begun.

The first is the “Postmodern essay generator”. Just keep clicking reload on this page to get a different randomly generated post-modern essay. Funny.

The second was reading about the Alan Sokal “Social Text” hoax article in 1996. Alan Sokal is a physicist who was concerned that the trendy postmodern academic world of literary and social studies was pointless – so he submitted a fairly blatant nonsense article to a peer reviewed academic journal, which got accepted!

The third would be all the new Christian trends and movements embracing postmodern substance or style. A sure sign that its faddish value is gone.

Stott gems on the motivations for world mission

Another Stott gem on an important topic:

“How then, can Christians justify the continuance of world evangelization? The commonest answer is to point to the Great Commission, and indeed obedience to it provides a strong stimulus. Compassion is higher than obedience, however, namely love for people who do not know Jesus Christ, and who on that account are alienated, disorientated, and indeed lost. But the highest incentive of all is zeal or jealousy for the glory of Jesus Christ. God has promoted him to the supreme place of honour, in order that every knee and tongue should acknowledge his lordship. Whenever he is denied his rightful place in people’s lives, therefore, we should feel inwardly wounded [like Paul in Acts 17:16], and jealous for his name.”
John Stott, “The Message of Acts”, IVP, p279.

What are our motivations for world and local evangelistic mission? Obedience, compassion but most of all jealousy for the honor of Jesus Christ.

The Lord Jesus Christ is both the “subject and object, source and goal, of evangelism, we have to repent of all self-centred, self-confident concepts of Christian mission”. Stott, “The Message of Acts”, IVP, p204.

Heavenly Father, show us the unsearchable riches of Jesus Christ and give us the joy of seeing those riches discovered by peoples all over the world and by those closest to us. In Jesus’ name, Amen.

Sermon: “Turning to the Goodness of the Living God” Acts 14:8-20

A new sermon in our church series on Acts.

“Wayne Schuller – ‘Turning to the Goodness of the Living God’ Acts 14-8-20 11-11-2005 10 30am”

I now have a cheapo ebay Asian mp3 player and recorder so it’s easier to make recordings.

Note to friends #1: I’m thankful for any feedback you could give – I want to be more faithful in this important part of my job. (email is probably better than blog comments)

Note to friends #2: Some of you have signed up for “notifications” of updates to this site. This doesn’t really work well from my end of things. So you won’t get emails reminders of updates on this site anymore. If you want to get automatically reminded of updates, you can subscribe to my RSS feed – there are special programs that do this, but I think Firefox can do it with it’s live bookmarks feature.

Sermon: Ephesians 6:10-20 Power in Prayer

A new sermon preached at our church on a series on prayer.

“Ephesians 6:10-20 Power in Prayer”

The audio quality is not great. I hope to get an mp3 player/recorder soon so I would like to post more sermons.

I would appreciate feedback and thoughts. I have some way to go both in terms of clarity and courage.

(Credits: There are a few Stott phrases and quotes from his BST commentary and some influence from a John Piper sermon on the same text)

Preaching With Clarity and Courage

John Stott on Ephesians 6:
“Clarity and courage remain two of the most crucial characteristics of authentic Christian preaching. For they relate to the content of the message preached and to the style of its presentation. Some preachers have the gift of lucid teaching, but their semrons lack solid content; their substance has become diluted by fear. Others are bold as lions. They fear nobody, and omit nothing. But what they say is confused and confusing. Clarity without courage is like sunshine in the desert: plenty of light but nothing worth looking at. Courage without clarity is like a beautiful landscape at night time: plenty to see, but no light by which to enjoy it. What is needed in the pulpits in the world today is a combination of clarity and courage, or of ‘utterance’ and ‘boldness’. Paul asked the Ephesians to pray that these might be give to him, for he recognized them as gifts of God. We should join them in prayer for the pastors and preachers of the contemporary church”.
Stott, “The Message of Ephesians”, Bible Speaks Today Series, p286.

Heavenly Father, help preachers today to proclaim the infinite worth of Jesus Christ with great clarity and fearless courage. To your glory and for our joy, Amen.

Strength for perseverance

I was encouraged by the observations and insights of John Piper in “The Roots of Endurance”:
“One of the pervasive marks of our times is emotional fragility. It hangs in the air we breath. We are easily hurt. We pout and mope easily. We blame easily. We break easily. Our marriages break easily. Our faith breaks easily. Our happiness breaks easily. And our commitment to the church breaks easily. We are easily disheartened, and it seems we have little capacity for surviving and thriving in the face of criticism and opposition… we are surrounded by, and are part of, a society of emotionally fragile quitters.” (p79-80).

These hard words ring true of my experience of Australian culture, including Christians. In one way, I am glad it is not just me. Only by comparing ourselves with Christians from other ages can we see this spotlight on ourselves.

John Piper’s suggestion is to watch people closely who are good at persevering in gospel commitment through emotional turmoil. That is why he wrote his book surveying the lives of Newton, Simeon and Wilberforce. I think this is good, and part of the answer.
